Hippophae is the genus of sea buckthorns, deciduous shrubs in the family Elaeagnaceae. The name sea buckthorn may be hyphenated [1] to avoid confusion with the unrelated true buckthorns (Rhamnus, family Rhamnaceae). It is also referred to as sandthorn, sallowthorn, [2] or seaberry. [3] It produces orange-yellow berries, which have been used over centuries as food, traditional medicine, and skin treatment in Mongolia, Ladakh, Russia, Ukraine, and northern Europe, which are its origin regions. [4]
They are exceptionally hardy plants, able to withstand winter temperatures as low as −43 °C (−45 °F). [4] Because Hippophae species develop an aggressive and extensive root system, they are planted to inhibit soil erosion and used in land reclamation for their nitrogen fixing properties, wildlife habitat, and soil enrichment. [5] Hippophae berries and leaves are manufactured into various human and animal food and skincare products. [4]
The shrubs reach 0.5–6 m (1 ft 8 in – 19 ft 8 in) tall, rarely up to 10 metres (33 ft) in central Asia. The leaf arrangement can be alternate or opposite. [6]
Hippophae is a small genus of Elaeagnaceae having a terminal taxon with seven species recognized, as of 2002. [6] Hippophae rhamnoides is a highly variable species with eight subspecies. [6]
In ancient times, leaves and young branches from sea buckthorn were supposedly fed as a remedy to horses to support weight gain and appearance of the coat, leading to the name of the genus, Hippophae derived from the Greek hippo (horse), and phaos (shining). [4]
Hippophae rhamnoides , the common sea buckthorn, is the most widespread of the species in the genus, with the ranges of its eight subspecies extending from the Atlantic coasts of Europe across to northwestern Mongolia, northwestern China and Northern Pakistan. [4] [9] In western Europe, it is largely confined to sea coasts where salt spray off the sea prevents other larger plants from outcompeting it. In central Asia, it is more widespread in dry semi-desert sites where other plants cannot survive the dry conditions.
In central Europe and Asia, it also occurs as a sub-alpine shrub above the tree line in mountains, and other sunny areas such as river banks where it has been used to stabilize erosion. [4] They are tolerant of salt in the air and soil, but demand full sunlight for good growth and do not tolerate shady conditions near larger trees. They typically grow in dry, sandy areas.
More than 90% or about 1,500,000 ha (3,700,000 acres) of the world's natural sea buckthorn habitat is found in China, Mongolia, Russia, and most parts of Northern Europe. [4]
Sea buckthorn USDA hardiness zones are about 3 through 7. [4]
In some areas it is considered invasive, due to its ability to outcompete smaller native species. [10]
During the Cold War, Russian and East German horticulturists developed new varieties with greater nutritional value, larger berries, different ripening months and branches that are easier to harvest. Over the past 20 years, experimental crops have been grown in the United States, one in Nevada and one in Arizona, and in several provinces of Canada. [11]
A study of nuclear ribosomal internal transcribed spacer sequence data [12] showed that the genus can be divided into three clades:
A study using chloroplast sequences and morphology, [9] however, recovered only two clades:
The fruit is an important winter food resource for some birds, notably fieldfares.[ citation needed ]
Leaves are eaten by the larva of the coastal race of the ash pug moth and by larvae of other Lepidoptera, including brown-tail, dun-bar, emperor moth, mottled umber, and Coleophora elaeagnisella .
Sea buckthorn berries are edible and nutritious, though astringent, sour, and oily [13] unless bletted (frosted to reduce the astringency) and/or mixed as a drink with sweeter substances such as apple or grape juice. Additionally, malolactic fermentation of sea buckthorn juice reduces sourness, enhancing its sensory properties. The mechanism behind this change is transformation of malic acid into lactic acid in microbial metabolism. [14]
When the berries are pressed, the resulting sea buckthorn juice separates into three layers: on top is a thick, orange cream; in the middle, a layer containing sea buckthorn's characteristic high content of saturated and polyunsaturated fats; and the bottom layer is sediment and juice. [4] [15] The upper two layers contain fat sources applicable for cosmetic purposes and can be processed for skin creams and liniments, whereas the bottom layer can be used for edible products such as syrup. [15]
Besides juice, sea buckthorn fruit can be used to make pies, jams, lotions, teas, fruit wines, and liquors. [4] The juice or pulp has other potential applications in foods, beverages, or cosmetics products such as shower gel. [4] Fruit drinks were among the earliest sea buckthorn products developed in China. Sea buckthorn-based juice is common in Germany and Scandinavian countries. It provides a beverage rich in vitamin C and carotenoids. [4] Sea buckthorn berries are also used to produce rich orange-coloured ice-cream, with a melon-type taste and hints of citrus. [16] [17]
For its troops confronting low winter temperatures (see Siachen), India's Defence Research and Development Organisation established a factory in Leh to manufacture a multivitamin herbal beverage based on sea buckthorn juice. [18]
The seed and pulp oils have nutritional properties that vary under different processing methods. [19] Sea buckthorn oils are used as a source for ingredients in several commercially available cosmetic products and nutritional supplements. [4]
Sea buckthorn may be used as a landscaping shrub with an aggressive basal shoot system used for barrier hedges and windbreaks, and to stabilize riverbanks and steep slopes. [4] They have value in northern climates for their landscape qualities, as the colorful berry clusters are retained through winter. [4] [5] [20] Branches may be used by florists for designing ornaments.
In northwestern China, sea buckthorn shrubs have been planted on the bottoms of dry riverbeds to increase water retention of the soil, thus decreasing sediment loss. [4] Because of increased moisture conservation of the soil and nitrogen-fixing capabilities of sea buckthorn, vegetation levels have increased in areas where sea buckthorn have been planted. [21] [22] Sea buckthorn was once distributed free of charge to Canadian prairie farmers by PFRA to be used in shelterbelts. [23]
Sea buckthorn has been used over centuries in traditional medicine. [4] Although sea buckthorn fruit extracts are under preliminary research for their pharmacological effects, there is no high-quality clinical evidence for the ability of Hippophae products to lower the risk of human diseases. [24] As of 2022, no sea buckthorn products are approved as prescription drugs by any national regulatory agency. [24]
Berry oil from seeds or fruit pulp, either taken orally as a dietary supplement or applied topically, is believed to be a skin softener or medicine, but there is inadequate clinical evidence of its effectiveness. [24] There have been no systematic studies of toxicity and safety for any Hippophae product. [24]
The International Seabuckthorn Association, formerly the International Center for Research and Training on Seabuckthorn (ICRTS), was formed jointly in 1988 by the China Research and Training Center on Seabuckthorn, the Seabuckthorn Office of the Yellow River Water Commission, and the Shaanxi Seabuckthorn Development Office. From 1995 to 2000, ICRTS published the research journal, Hippophae, which appears to be no longer active.
In 2005 - 2007, the "EAN-Seabuck" network between European Union states, China, Russia and New Independent States was funded by the European Commission to promote sustainable crop and consumer product development. [25]
In Mongolia, there is an active National Association of Seabuckthorn Cultivators and Producers. [26]
Cranberries are a group of evergreen dwarf shrubs or trailing vines in the subgenus Oxycoccus of the genus Vaccinium. In Britain, cranberry may refer to the native species Vaccinium oxycoccos, while in North America, cranberry may refer to Vaccinium macrocarpon. Vaccinium oxycoccos is cultivated in central and northern Europe, while Vaccinium macrocarpon is cultivated throughout the northern United States, Canada and Chile. In some methods of classification, Oxycoccus is regarded as a genus in its own right. Cranberries can be found in acidic bogs throughout the cooler regions of the Northern Hemisphere.
Citrus is a genus of flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including crops such as oranges, lemons, grapefruits, pomelos, and limes. The genus Citrus is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion ; and to the Middle East and the Mediterranean via the incense trade route, and onwards to Europe and the Americas.
A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a stone or pit, although many pips or seeds may be present. Common examples of berries in the culinary sense are strawberries, raspberries, blueberries, blackberries, white currants, blackcurrants, and redcurrants. In Britain, soft fruit is a horticultural term for such fruits.
The blackcurrant, also known as black currant or cassis, is a deciduous shrub in the family Grossulariaceae grown for its edible berries. It is native to temperate parts of central and northern Europe and northern Asia, where it prefers damp fertile soils. It is widely cultivated both commercially and domestically.
The Elaeagnaceae are a plant family, the oleaster family, of the order Rosales comprising small trees and shrubs, native to temperate regions of the Northern Hemisphere, south into tropical Asia and Australia. The family has about 60 species in three genera.
Passiflora edulis, commonly known as passion fruit, is a vine species of passion flower native to southern Brazil and Peru. It is cultivated commercially in tropical and subtropical areas for its sweet, seedy fruit. The fruit is a pepo, a type of berry, round to oval, either yellow or dark purple at maturity, with a soft to firm, juicy interior filled with numerous seeds. The fruit is both eaten and juiced, with the juice often added to other fruit juices to enhance aroma.
Aronia is a genus of deciduous shrubs, the chokeberries, in the family Rosaceae native to eastern North America and most commonly found in wet woods and swamps. The genus Aronia is considered to have 3 species. The most common and widely used is Aronia melanocarpa which emerged from Eastern North America. The lesser known Aronia arbutifolia and the hybrid form of the abovementioned species called Aronia prunifolia were first cultivated in Central and Eastern North America. In the eighteenth century, the first shrubs of the best-known species Aronia melanocarpa reached Europe where they were first cultivated in Scandinavia and Russia.
Rhamnus is a genus of about 140 accepted species of shrubs or small trees, commonly known as buckthorns, in the family Rhamnaceae. Its species range from 1 to 10 m tall and are native mainly in east Asia and North America, but found throughout the temperate and subtropical Northern Hemisphere, and also more locally in the subtropical Southern Hemisphere in parts of Africa and South America. One species, the common buckthorn, is able to flourish as an invasive plant in parts of Canada and the U.S., where it has become naturalized.
Goji, goji berry, or wolfberry is the sweet fruit of either Lycium barbarum or Lycium chinense, two closely related species of boxthorn in the nightshade family, Solanaceae. L. barbarum and L. chinense fruits are similar but can be distinguished by differences in taste and sugar content.
The açaí palm, Euterpe oleracea, is a species of palm tree (Arecaceae) cultivated for its fruit, hearts of palm, leaves, and trunk wood. Global demand for the fruit has expanded rapidly in the 21st century, and the tree is cultivated for that purpose primarily.
Frangula is a genus of about 35 species of flowering shrubs or small trees, commonly known as alder buckthorn in the buckthorn family Rhamnaceae. The common name buckthorn is also used to describe species of the genus Rhamnus in the same family and also sea-buckthorn, Hippophae rhamnoides in the Elaeagnaceae.
Lycium barbarum is a shrub native to China, with present-day range across Asia and southeast Europe. It is one of two species of boxthorn in the family Solanaceae from which the goji berry or wolfberry is harvested, the other being Lycium chinense.
Hippophae rhamnoides, also known as sea-buckthorn, is a species of flowering plant in the family Elaeagnaceae, native to the cold-temperate regions of Europe and Asia. It is a spiny deciduous shrub. The plant is used in the food and cosmetics industries, in traditional medicine, as animal fodder, in horticulture, and for ecological purposes.
Palmitoleic acid, or (9Z)-hexadec-9-enoic acid, is an omega-7 monounsaturated fatty acid (16:1n-7) with the formula CH3(CH2)5CH=CH(CH2)7COOH. It is a rare component of fats. It is a common constituent of the glycerides of human adipose tissue. It is present in all tissues but, in general, found in higher concentrations in the liver.
Vaccinium myrtillus or European blueberry is a holarctic species of shrub with edible fruit of blue color, known by the common names bilberry, blaeberry, wimberry, and whortleberry. It is more precisely called common bilberry or blue whortleberry to distinguish it from other Vaccinium relatives.
In botany, a berry is a fleshy fruit without a stone (pit) produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines), persimmons and bananas, but exclude certain fruits that meet the culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more carpels from the same flower. The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as Capsicum species, with air rather than pulp around their seeds.
Sea buckthorn oil is a red-orange oil derived from sea buckthorn plants. The most commonly used species for this purpose is Hippophae rhamnoides. Species belonging to this genus accumulate lipids in the mesocarp, so the oil can be extracted from either the seeds or the pulp.
Rhamnus cathartica, the European buckthorn, common buckthorn, purging buckthorn, or just buckthorn, is a species of small tree in the flowering plant family Rhamnaceae. It is native to Europe, northwest Africa and western Asia, from the central British Isles south to Morocco, and east to Kyrgyzstan. It was introduced to North America as an ornamental shrub in the early 19th century or perhaps before, and is now naturalized in the northern half of the continent, and is classified as an invasive plant in several US states and in Ontario, Canada.
Frangula alnus, commonly known as alder buckthorn, glossy buckthorn, or breaking buckthorn, is a tall deciduous shrub in the family Rhamnaceae. Unlike other "buckthorns", alder buckthorn does not have thorns. It is native to Europe, northernmost Africa, and western Asia, from Ireland and Great Britain north to the 68th parallel in Scandinavia, east to central Siberia and Xinjiang in western China, and south to northern Morocco, Turkey, and the Alborz in Iran and the Caucasus Mountains; in the northwest of its range, it is rare and scattered. It is also introduced and naturalised in eastern North America.
Iris goniocarpa is a plant species in the genus Iris, it is also in the subgenus of Iris and in the section Pseudoregelia. It is a rhizomatous perennial, from China, India, Burma and Bhutan. It has yellow green to dark green, long leaves, slender stem and, one flower between blue, lavender-blue, lilac, blue-violet or blue-purple. It is cultivated as an ornamental plant in temperate regions.
