Aristotelia chilensis, known as maqui or Chilean wineberry, is a tree species in the Elaeocarpaceae family native to South America in the Valdivian temperate forests of Chile and adjacent regions of southern Argentina. Limited numbers of these trees are cultivated in gardens for their small edible fruits. Wild-harvested fruits are commercially marketed.
The species has drawn attention for its forensic potential as it is reported to be among the first plants to grow around pig carcasses, which are experimental substitutes for human corpses, in southern Chile. [2]
Aristotelia chilensis is a small dioecious evergreen tree that can reach 4 to 5 metres (13 to 16 ft) in height. Its divided trunk has a smooth bark. Its branches are abundant, thin and flexible. Its leaves are simple, opposite, hanging, oval-lanceolate, naked and coriaceous, with serrated edges. The leaf venation is highly visible, and the leaf stalk is a strong red color.
In the beginning of spring, the tree sheds the old leaf cohort, which is used as a carbohydrate source to form the new leaves and flowers. [3]
When A. chilensis flowers at the end of spring, the white flowers are unisexual and small, eventually yielding a small edible fruit. The small purple-black berries that form are approximately 4 to 6 millimetres (0.16 to 0.24 in) in diameter and contain 4 to 8 angled seeds. A seven-year-old tree can produce up to 10 kilograms (22 lb) of berries per year. With fruit that tastes similar to blackberries, the species is known as the Chilean wineberry, and locally in Spanish as maqui or maque.
The maqui was first scientifically described by Juan Ignacio Molina in 1782, who named it Cornus chilensis. In 1914, Stephen Conrad Stuntz assigned it to the genus Aristotelia that had been erected by Charles Louis L'Héritier de Brutelle in 1786, and made the new combination A. chilensis. [4]
Aristotelia chilensis is native to Chile and Argentina near the southwest coast of South America. [1] It is found naturally in Chilean rainforests. Its native range spans the area between the Coquimbo and Aysén regions of Chile, and is 170,000 hectares (420,000 acres) in total. [5]
Maqui berries are a favored food for birds at the end of summer. Deforestation of the Valdivian temperate forests in Chile suppresses seed dispersal by birds and leads to inbreeding depression. [6]
The berries of A. chilensis are collected from wild plants from December to March of each year by families, mainly Mapuche, who collect their harvest near the Andes Mountains. The harvesting process involves collecting the side branches of trees, shaking them to separate the berries and leaves from the branches, and then employing a mechanical process to separate the berries from the leaves.
The stored fruits are sold in local markets, with prices ranging from $6.5 to $15 per kilogram ($2.9 to $6.8/lb). The average area yield is about 220 kilograms (490 lb) per hectare annually, with an estimated yearly total of only 90 short tons (180,000 lb),[ citation needed ] due to remote access and difficulty of transportation.
Aristotelia chilensis is planted in home gardens and is not grown on an orchard scale. Most of the fruits on the market have been gathered from the wild. Maqui is frost sensitive and fairly tolerant of seaside conditions. It prefers a well-drained soil in full sun, with some protection against cold, drying winds. The soil should be slightly acidic, with moderate fertility. [7]
Aristotelia chilensis can be planted in USDA zones 8 to 12. It is cultivated in Spain, and in milder, moister areas of Britain, where winter freezes cause dieback, thereby stimulating growth of more shoots in spring. [8]
Seeds of A. chilensis germinate without cold stratification. In zones with the possibility of frost, it is recommended to sow in spring in a greenhouse. If they have grown enough, by autumn, the new plants can be planted into individual pots . The potted plants should stay in the greenhouse for the first winter.
The following year, after the last expected frost in spring, the plants can be planted out into their final positions. In their first winter outdoors, some type of frost protection is required. [9] For further propagation, vegetative propagation is possible: cuttings of wood with a length of 15 to 30 centimetres (5.9 to 11.8 in) can be planted into pots. These cuttings normally root, and can be planted out in the following spring. [10]
Polyphenol research on maqui berries showed anthocyanin content to include eight glucoside pigments of delphinidin and cyanidin, with the principal anthocyanin being delphinidin 3-sambubioside-5-glucoside (34% of total anthocyanins). [11] [12] [13] The average total anthocyanin content was 138 milligrams (2.13 gr) per 100 grams (3.5 oz) of fresh fruit, or 212 milligrams (3.27 gr) per 100 grams (3.5 oz) of dry fruit, [13] ranking maqui berries low among darkly pigmented fruits for anthocyanin content (see table at anthocyanins). One study found that anthocyanins are also present in maqui leaves. [14]
Other phytochemicals extracted from the leaves of A. chilensis were the alkaloids aristoteline, aristoquinoline, and aristone. [15]
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, red currants, white currants and blackcurrants. In Britain, soft fruit is a horticultural term for such fruits.
The blackberry is an edible fruit produced by many species in the genus Rubus in the family Rosaceae, hybrids among these species within the subgenus Rubus, and hybrids between the subgenera Rubus and Idaeobatus. The taxonomy of blackberries has historically been confused because of hybridization and apomixis, so that species have often been grouped together and called species aggregates. For example, the entire subgenus Rubus has been called the Rubus fruticosus aggregate, although the species R. fruticosus is considered a synonym of R. plicatus.
Morus, a genus of flowering plants in the family Moraceae, consists of diverse species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. Generally, the genus has 64 subordinate taxa, three of which are well-known and are ostensibly named for the fruit color of the best-known cultivar: white, red, and black mulberry, with numerous cultivars and some taxa currently unchecked and awaiting taxonomic scrutiny. M. alba is native to South Asia, but is widely distributed across Europe, Southern Africa, South America, and North America. M. alba is also the species most preferred by the silkworm, and is regarded as an invasive species in Brazil and the United States.
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.
Bilberries or blueberries are a primarily Eurasian species of low-growing shrubs in the genus Vaccinium, bearing edible, dark blue berries. The species most often referred to is Vaccinium myrtillus L., but there are several other closely related species.
The raspberry is the edible fruit of a multitude of plant species in the genus Rubus of the rose family, most of which are in the subgenus Idaeobatus. The name also applies to these plants themselves. Raspberries are perennial with woody stems. World production of raspberries in 2020 was 895,771 tonnes, led by Russia with 20% of the total.
Ripening is a process in fruits that causes them to become more palatable. In general, fruit becomes sweeter, less green, and softer as it ripens. Even though the acidity of fruit increases as it ripens, the higher acidity level does not make the fruit seem tarter. This effect is attributed to the Brix-Acid Ratio. Climacteric fruits ripen after harvesting and so some fruits for market are picked green.
Vitis vinifera, the common grape vine, is a species of flowering plant, native to the Mediterranean region, Central Europe, and southwestern Asia, from Morocco and Portugal north to southern Germany and east to northern Iran. There are currently between 5,000 and 10,000 varieties of Vitis vinifera grapes though only a few are of commercial significance for wine and table grape production.
Amelanchier alnifolia, the saskatoon berry, Pacific serviceberry, western serviceberry, western shadbush, or western juneberry, is a shrub with an edible berry-like fruit, native to North America.
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.
Aristotelia serrata, commonly known as wineberry or in the Māori language makomako or just mako, is a small tree in the family Elaeocarpaceae, in the genus Aristotelia, found in the North Island, South Island and Stewart Island of New Zealand. It is a small deciduous fast-growing tree or shrub. The tree can reach up to 10m tall, with a trunk diameter up to 30 cm. The bark is pale brown, smooth and patterned with flat lenticels. Branches are long, slender and spreading, branchlets have a reddish-brown color when pubescent.
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.
Delphinidin is an anthocyanidin, a primary plant pigment, and also an antioxidant. Delphinidin gives blue hues to flowers in the genera Viola and Delphinium. It also gives the blue-red color of the grape variety Cabernet Sauvignon, and can be found in cranberries and Concord grapes as well as pomegranates, and bilberries.
The garden strawberry is a widely grown hybrid species of the genus Fragaria, collectively known as the strawberries, which are cultivated worldwide for their fruit. The fruit is widely appreciated for its characteristic aroma, bright red color, juicy texture, and sweetness. It is consumed in large quantities, either fresh or in such prepared foods as jam, juice, pies, ice cream, milkshakes, and chocolates. Artificial strawberry flavorings and aromas are also widely used in products such as candy, soap, lip gloss, perfume, and many others.
Schisandra chinensis, whose fruit is called magnolia berry or five-flavor fruit, is a vine plant native to forests of Northern China, the Russian Far East and Korea. Wild varieties are also found in Japan. It is hardy in USDA Zone 4. The fruits are red berries in dense clusters around 10 centimetres (3.9 in) long.
Lonicera caerulea, also known by its common names blue honeysuckle, sweetberry honeysuckle, fly honeysuckle, blue-berried honeysuckle, or the honeyberry, is a non-climbing honeysuckle native throughout the cool temperate Northern Hemisphere regions of North America, Europe, and Asia.
Autumn leaf color is a phenomenon that affects the normally green leaves of many deciduous trees and shrubs by which they take on, during a few weeks in the autumn season, various shades of yellow, orange, red, purple, and brown. The phenomenon is commonly called autumn colours or autumn foliage in British English and fall colors, fall foliage, or simply foliage in American English.
Anthocyanins, also called anthocyans, are water-soluble vacuolar pigments that, depending on their pH, may appear red, purple, blue, or black. In 1835, the German pharmacist Ludwig Clamor Marquart gave the name Anthokyan to a chemical compound that gives flowers a blue color for the first time in his treatise "Die Farben der Blüthen". Food plants rich in anthocyanins include the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black. Some of the colors of autumn leaves are derived from anthocyanins.
The phenolic content in wine refers to the phenolic compounds—natural phenol and polyphenols—in wine, which include a large group of several hundred chemical compounds that affect the taste, color and mouthfeel of wine. These compounds include phenolic acids, stilbenoids, flavonols, dihydroflavonols, anthocyanins, flavanol monomers (catechins) and flavanol polymers (proanthocyanidins). This large group of natural phenols can be broadly separated into two categories, flavonoids and non-flavonoids. Flavonoids include the anthocyanins and tannins which contribute to the color and mouthfeel of the wine. The non-flavonoids include the stilbenoids such as resveratrol and phenolic acids such as benzoic, caffeic and cinnamic acids.
Myrtillin is an anthocyanin. It is the 3-glucoside of delphinidin. It can be found in all green plants, most abundantly in black beans, blackcurrant, blueberry, huckleberry, bilberry leaves and in various myrtles, roselle plants, and Centella asiatica plant. It is also present in yeast and oatmeal. The sumac fruit's pericarp owes its dark red colour to anthocyanin pigments, of which chrysanthemin, myrtillin and delphinidin have yet been identified.
