Ipomoea purpurea | |
Ipomoea purpurea, the common morning-glory, [2] tall morning-glory, [3] or purple morning glory, is a species in the genus Ipomoea , native to Mexico [4] and Central America.
Like all morning glories, the plant entwines itself around structures, growing to a height of 2–3 m (6 ft 7 in – 9 ft 10 in) tall. The leaves are heart-shaped and the stems are covered with brown hairs. The flowers are trumpet-shaped, predominantly blue to purple or white, and 3–6 cm (1.2–2.4 in) in diameter. [5]
The plant is predisposed to moist and rich soil, but can be found growing in a wide array of soil types. [6] It is naturalized throughout warm temperate and subtropical regions of the world. Although it is often considered a noxious weed, I. purpurea is also grown for its attractive purple and white flowers, and has many cultivars. Common cultivars include I. purpurea 'Crimson Rambler' (red-violet blossoms with white throats), 'Grandpa Ott's', 'Kniola's Black Knight', 'Star of Yelta' (blossoms in varying shades of deep purple with white or pale pink throats), and 'Milky Way' (white corolla with mauve accents).
The triangular seeds have some history of use as a psychedelic; they, like I. tricolor , may contain LSA. [6] Effects are reported to be somewhat similar to those of LSD. [7]
Acylated cyanidin glycosides can be isolated from violet-blue flowers of I. purpurea. These anthocyanins were all based on cyanidin 3-sophoroside-5-glucoside, acylated with caffeic acid and/or p-coumaric acid. [8]
Acylated pelargonidin glycosides can be isolated from the red-purple flowers of I. purpurea. The acylated anthocyanins were all based on pelargonidin 3-sophoroside-5-glucoside, acylated with caffeic acid and/or glucosylcaffeic acid. [9]
Commercial morning glory seeds are commonly treated with toxic methylmercury, which serves as a preservative and a cumulative neurotoxic poison that is considered useful by some to discourage their recreational use. The US has no legal requirement to disclose to buyers that seeds have been treated with a toxic heavy metal compound. [10] According to the book Substances of Abuse, in addition to methylmercury, the seeds are commonly coated with a chemical [ which? ] that cannot be removed with washing that is designed to cause unpleasant physical symptoms, such as nausea and abdominal pain. The book states that this chemical is also toxic. [11]
Morning glory is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose current taxonomy and systematics are in flux. Morning glory species belong to many genera, some of which are:
Anthocyanidins are common plant pigments, the aglycones of anthocyanins. They are based on the flavylium cation, an oxonium ion, with various groups substituted for its hydrogen atoms. They generally change color from red through purple, blue, and bluish green as a function of pH.
Ipomoea is the largest genus in the plant family Convolvulaceae, with over 600 species. It is a large and diverse group, with common names including morning glory, water convolvulus or water spinach, sweet potato, bindweed, moonflower, etc. The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual and perennial herbaceous plants, lianas, shrubs, and small trees; most of the species are twining climbing plants.
Ipomoea tricolor, the Mexican morning glory or just morning glory, is a species of flowering plant in the family Convolvulaceae, native to the tropics of the Americas, and widely cultivated and naturalised elsewhere.
Hydrangea macrophylla is a species of flowering plant in the family Hydrangeaceae, native to Japan. It is a deciduous shrub growing to 2 m (7 ft) tall by 2.5 m (8 ft) broad with large heads of pink or blue flowers in summer and autumn. Common names include bigleaf hydrangea, French hydrangea, lacecap hydrangea, mophead hydrangea, and hortensia. It is widely cultivated in many parts of the world in many climates. It is not to be confused with H. aspera 'Macrophylla'.
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.
Cyanidin is a natural organic compound. It is a particular type of anthocyanidin. It is a pigment found in many red berries including grapes, bilberry, blackberry, blueberry, cherry, chokeberry, cranberry, elderberry, hawthorn, loganberry, açai berry and raspberry. It can also be found in other fruits such as apples and plums, and in red cabbage and red onion. It has a characteristic reddish-purple color, though this can change with pH; solutions of the compound are red at pH < 3, violet at pH 7-8, and blue at pH > 11. In certain fruits, the highest concentrations of cyanidin are found in the seeds and skin. Cyanidin has been found to be a potent sirtuin 6 (SIRT6) activator.
Paeonia lactiflora is a species of herbaceous perennial flowering plant in the family Paeoniaceae, native to central and eastern Asia from eastern Tibet across northern China to eastern Siberia.
Malvidin is an O-methylated anthocyanidin, the 3',5'-methoxy derivative of delphinidin. As a primary plant pigment, its glycosides are highly abundant in nature.
Peonidin is an O-methylated anthocyanidin derived from Cyanidin, and a primary plant pigment. Peonidin gives purplish-red hues to flowers such as the peony, from which it takes its name, and roses. It is also present in some blue flowers, such as the morning glory.
Ipomoea indica is a species of flowering plant in the family Convolvulaceae, known by several common names, including blue morning glory, oceanblue morning glory, koali awa, and blue dawn flower. It bears heart-shaped or three-lobed leaves and purple or blue funnel-shaped flowers 6–8 cm (2–3 in) in diameter, from spring to autumn. The flowers produced by the plant are hermaphroditic. This plant has gained the Royal Horticultural Society's Award of Garden Merit.
Ipomoea hederacea, the ivy-leaved morning glory or Kaladana, is a flowering plant in the bindweed family. The species is native to tropical parts of the Americas, and has more recently been introduced to North America. It now occurs there from Arizona to Florida and north to Ontario and North Dakota. Like most members of the family, it is a climbing vine with alternate leaves on twining stems. The flowers are blue to rose-purple with a white inner throat and emerge in summer and continue until late fall. The leaves are typically three-lobed, but sometimes may be five-lobed or entire. Flowers occur in clusters of one to three and are 2.5–4.5 cm long and wide. The sepals taper to long, recurved tips and measure 12–24 mm long. The species shares some features with the close relative Ipomoea purpurea, and is almost identical in appearance to wild forms of I. nil.
Ipomoea nil is a species of Ipomoea morning glory known by several common names, including picotee morning glory, ivy morning glory, ivy-leaf morning glory, and Japanese morning glory. It is native to the tropical Americas, and has been introduced widely across the world.
Pelargonidin is an anthocyanidin, a type of plant pigment producing a characteristic orange color used in food and industrial dyes.
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 named a chemical compound that gives flowers a blue color, Anthokyan, 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.
Phenolic compounds—natural phenol and polyphenols—occur naturally in wine. These 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.
Chrysanthemin is an anthocyanin. It is the 3-glucoside of cyanidin (kuromanin).
Sambubiose is a disaccharide. It is the β-D-xylosyl-(1→2)-β-D-glucose.
Violdelphin is an anthocyanin, a plant pigment, has been found in the purplish blue flower of Aconitum chinense, in the blue flowers in the genus Campanula and in the blue flowers of Delphinium hybridum. It is a flavenoid natural product, incorporating two p-hydroxy benzoic acid residues, one rutinoside and two glucosides associated with a delphinidin.
Blue flowers are rare in nature, and despite many attempts, blue roses, carnations and chrysanthemums in particular cannot not be produced by conventional breeding techniques. Blue colour in flower petals is caused by delphinidin, a type of anthocyanin, which are a class of flavonoids.
