“…Calystegines B1 and B2 (16 and 17) that are potent inhibitors of rat lysosomal β-glucosidase besides A3, B3 and the alkaloid 2α, 7β-dihidroxinortropano were identified in the roots of I. batatas (Schimming et al, , 2005a). Study in rats has shown that I. batatas leave are a good source of polyphenols, antioxidants and displayed vascular relaxing properties.…”

Approximately 600-700 species of Ipomoea, Convolvulaceae, are found throughout tropical and subtropical regions of the world. Several of those species have been used as ornamental plants, food, medicines or in religious ritual. The present work reviews the traditional uses, chemistry and biological activities of Ipomoea species and illustrates the potential of the genus as a source of therapeutic agents. These species are used in different parts of the world for the treatment of several diseases, such as, diabetes, hypertension, dysentery, constipation, fatigue, arthritis, rheumatism, hydrocephaly, meningitis, kidney ailments and infl ammations. Some of these species showed antimicrobial, analgesic, spasmolitic, spasmogenic, hypoglycemic, hypotensive, anticoagulant, anti-infl ammatory, psychotomimetic and anticancer activities. Alkaloids, phenolics compounds and glycolipids are the most common biologically active constituents from these plant extracts.

“…F. repens is a small, prostrate, often matted, perennial herb, whereas A. malvacea, also widespread from western tropical Africa to eastern Africa, is a perennial subshrub. Both genera have not been investigated yet phytochemically apart from the detection of calystegins, hydrophilic nor-tropane derivatives in F. repens [5].…”

An unusual and complex tropane alkaloid pattern has been detected in the root bark of Astripomoea malvacea and in the whole plant of Falkia repens (Convolvulaceae) by GC-MS analysis. The specific profile of both species is characterized by the presence of aliphatic 3-acyloxytropanes/-nortropanes (exclusively in A. malvacea; predominantly in F. repens in cooccurrence with a few aromatic as well as arylalkyl acyl congeners). The principal alkaloid of A. malvacea, astrimalvine A N-oxide [3β -(3-tigloyloxy-2-methylbutyryloxy)tropane N-oxide], isolated and structurally elucidated by detailed spectroscopic analysis, represents the first N-oxide of a 3β -tropanol derivative in the Convolvulaceae. Its minor tertiary congener astrimalvine B [3β -(3-hydroxy-2-methylbutyryloxy)tropane] turned out to be a metabolite of both convolvulaceaous species. This is the first phytochemical report on the African genera Astripomoea and Falkia.
