The bioassay-guided fractionation of the extracts of Plumeria rubra barks also proved to be a successful strategy, leading to the isolation of eleven substances, of which eight were iridoids. In this context, the aqueous extract of Plumeria rubra bark has iridoids such as the epimers, a-allamcidin and (l-allamcidin, which were resolved by preparative TLC on Si-gel G plates (20 x 20 cm, 250 pm, Merck ), using chloroform/ethyl acetate/methanol (3 3 1) as solvent system [44]. [Pg.162]

According to [44] the iridoids fulvoplumierin, allamandin, a- and jl-allamcidin, plumieride, 15-demethylplumieride, 13-O-trflMS-p-coumaroylplumieride and plumericin are present in extracts of Plumeria rubra. For isolation of these iridoids, the stem bark (2.5 kg) was successively extracted with petroleum ether and methanol followed by bioguided fractionation to investi-... [Pg.164]

The iridoids, plumericin, isoplumericin, plumieride and fulvoplumierin, were present in the extracts of Plumeria rubra bark. After maceration of the powdered bark (3.5 kg) with dichloro-methane/methanol (1 1) and pure methanol, the combined extracts were partitioned between water and ethyl acetate. To isolate the four iridoids, the organic layer was chromatographed twice in a column using silica gel and gradient of increasing polarity with hexane and ethyl acetate, ethyl acetate and methanol, and then pure methanol. The amounts of the compounds isolated were not reported [75]. [Pg.165]

The flowers of Plumeria rubra L. cv. acutifolia can provide plumericidine, as described by [97]. The ethanol (95%) extract, obtained from 2.9 kg of flowers, was successively parhhoned with petroleum ether, ethyl acetate and butanol. The ethyl acetate fraction was sequentially submitted twice to column chromatography using silica gel and gradient of chloroform/ methanol as mobile phase. Chromatography on a Sephadex LH20 column yielded 20 mg of plumericidine. [Pg.166]
