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.

Contents

Description

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]

Distribution and habitat

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).

Chemistry

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]

Flower color

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]

Toxic treatments

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 Common name for more than 1,000 species of flowering plants in the family Convolvulaceae

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:

It is an herbaceous annual or perennial twining liana growing to 2–4 m (7–13 ft) tall. The leaves are spirally arranged, 3–7 cm (1–3 in) long with a 1.5–6 cm long petiole. The flowers are trumpet-shaped, 4–9 cm (2–4 in) in diameter, most commonly blue with a white to golden yellow centre.

<i>Digitalis purpurea</i> Toxic flowering plant in the family Plantaginaceae

Digitalis purpurea, the foxglove or common foxglove, is a poisonous species of flowering plant in the plantain family Plantaginaceae, native to and widespread throughout most of temperate Europe. It has also naturalised in parts of North America and some other temperate regions. The plant is a popular garden subject, with many cultivars available. It is the original source of the heart medicine digoxin. This biennial plant grows as a rosette of leaves in the first year after sowing, before flowering and then dying in the second year. It generally produces enough seeds, however, so that new plants will continue to grow in a garden setting.

<i>Hydrangea macrophylla</i> Species of flowering plant in the family Hydrangeaceae

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, penny mac 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'.

Cyanidin Anthocyanidin pigment in flowering plant plant petals and fruits

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.

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.

Anthocyanin Class of chemical compounds

Anthocyanins 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.

<i>Ipomoea lacunosa</i> Species of flowering plant

Ipomoea lacunosa, the whitestar, white morning-glory or pitted morningglory, is a species that belongs to the genus Ipomoea. In this genus most members are commonly referred to as "morning glories". The name for the genus, Ipomoea, has root in the Greek words ips and homoios, which translates to worm-like. This is a reference to the plant's vine-like growth. Lacunosa comes from a Latin word meaning air spaces, correlating with the venation of the leaves. Ipomoea lacunosa is native to the United States and grows annually. The flowers of this species are usually white and smaller than most other morning glories.

Basics of blue flower colouration

Blue flower colour was always associated with something unusual and desired. Blue roses especially were assumed to be a dream that cannot be realised. Blue colour in flower petals is caused by anthocyanins, which are members of flavonoid class metabolites. We can diversify three main classes of anthocyanin pigments: cyaniding type responsible for red coloration, pelargonidin type responsible for orange colour and delphinidin type responsible for violet/blue flower and fruits coloration. The main difference in the structure of listed anthocyanins type is the number of hydroxyl groups in the B-ring of the anthocyanin. Nevertheless, in the monomeric state anthocyanins never show blue colour in the weak acidic and neutral pH. The mechanism of blue colour formation are very complicated in most cases, presence of delphinidin type pigments is not sufficient, great role play also the pH and the formation of complexes of anthocyanins with flavones and metal ions.
