| Abstract: | Two sterols have been isolated from the chloroform extract of Melothria
purpusila and are widely used in Manipur for curing jaundice, as
ergosta-7.22-dien-3 ,5 ,6-triol 1 and 3-O--D-glucopyranosyl-ergosta-7,22-dien-5 ,6-diol 2. The n-butanol
extract fractionated from methanol extract yields flavonol glycosides 3-5
after eluting with solvents of different polarities. These compounds have been
identified as quercetin 4'-O-β-D-galactoside 3, kaempferol 3-O--D-glucosyl (1→2)--D-glucoside
4, and quercetin 3-O--D-glucosyl (1→2)--D-galactoside
7-O--D-glucoside
