Ipomoea tricolor

Plate 1. Ethnobotany and Background. Convolvulaceae, the botanical name for the morning glory family, derives from the Latin convolve, referring to its growth of intertwining vines (A Heavenly blue, Ipomoea tricolor). The purgative properties of the Mexican roots were readily accepted in Europe when introduced in the sixteenth century, since pre-Christian folk tradition had already proclaimed the virtues of skammonia as found in Dioscorides work De Materia Medica, ca. 50-68 a.d.

Taxonomically, the genus Ipomoea is extremely difficult. The binomial Ipomoea tricolor has already crept into the limited literature that has groyrn up in connection with this second kind, of ololiuqui. Inasmuch as some confusion may result in the use of two names— ipomoea tricolor and I. violacea- we should point out that, after a study ofplant material and the taxonomic history of these binomials, I am in agreement with the American specialist in the Convolvulaceae, H. D. House (House, H. D. The North American species of the genus Ipomoea in Ann. N.Y. Acad. Sci. 18 C19083 259), that both names actually refer to one polymorphic species. In this case, then, the older name is Ipomoea Violacea L. Sp. Pl. (1753) 161, which should be used in preference to its synonym I. tricolor Cav. Ic. Pl. Par. 3 (1794) 5, t. 208.

Tricolorin A (46) and G (47) are prototype members of this class of amphiphilic glycoconjugates (24). They constitute the allelochemical principles of Ipomoea tricolor Cav., a plant used in traditional agriculture in Mexico as a cover crop to protect sugar cane against invasive weeds. Their molecular mechanism of action likely involves the inhibition of the FT-ATPase of the plasma membrane, an enzyme that plays a crucial role in plant cell physiology. Moreover, 46 acts as a natural uncoupler of photophosphorylation in spinach chloroplasts. This compound also displays general cytotoxicity against several...

A facile synthesis of two naturally occurring 3-deoxyanthocyanidins from 2,4,6-triacetoxybenzaldehyde has been described <03S1878>. A one-step route to pyranoanthocyanins, molecules that have been found in red wine <03TL4887>, involves initial reaction under aqueous conditions of cinnamic acids at the electrophilic 4-position of anthocyanins followed by an intramolecular cyclisation and decarboxylation <03TL7583>. A tri-( )-caffeoyl anthocyanin present in the blue petals of morning glory, Ipomoea tricolor, is resistant to ,Z-isomerisation by UV-B irradiation, a property that may be important in plant survival <03TL7875>.
