The compounds 1-6 were isolated from the heartwood of Plumeria rubra, following bioactivity-directed fractionation. Plumericin 1 and isoplumericin 2 displayed molluscicidal, cytotoxic and antibacterial activity, 4-hydroxyacetophenone 3 was weakly cytotoxic, whereas the remaining glycosidic isolates
Four new iridoids viz., plumeridoids A, B, and C and epiplumeridoid C were isolated from the stem bark of Plumeria rubra Linn. together with twenty-four known compounds viz., 1-( P-hydroxyphenyl)propan-1-one, isoplumericin, plumericin, dihydroplumericin, allamcin, fulvoplumerin, allamandin,
In search of a new potent as an antioxidant from natural sources, plumieride-an iridoid isolated from the methanol extract of the bark of Plumeria bicolor (family Apocynaceae) was evaluated for its antioxidant potential against CCl₄-induced peroxidative damage in liver of rats. The antioxidant
By bioactivity-directed fractionation, six cytotoxic constituents have been characterized from the bark of Plumeria rubra collected in Indonesia. Three iridoids, fulvoplumierin [1], allamcin [2], and allamandin [3], as well as 2,5-dimethoxy-p-benzoquinone [4], were found to be active constituents of
Ethnopharmacological relevance: Plumeria rubra L. (Apocynaceae) is a deciduous, commonly ornamental, tropical plant grown in home premises, parks, gardens, graveyards, because of its beautiful and attractive flowers of various colours and
