Abstract:
Sixteen compounds were isolated from the aerial parts of Euphorbia sikkimensis by means of various chromatographic techniques such as silica gel, Sephades LH-20 and RP-18, and their structures were elucidated as naringenin (1), kaempferol (2), quercetin (3), kaempferol-3-O-alpha-L-arabinopyranoside (4), quercetin-3-O-alpha-L-arabinopyranoside (5), quercetin-3-O-(2"-galloyl)-alpha-L-arabinopyranoside (6), 5alpha, 8alpha-epidioxy-(22E, 24R)-ergosta-6,22-dien-3beta-ol (7), stigmast-5-ene-7-one-3beta-ol (8), 3beta-hydroxy4a, 14alpha-dimethyl-5alpha-ergosta-8, 24(28)-dien-7-one(9), beta-sitosterol (10) , 10-cucurbitadienol( 1) , scopoletin(12) , ethyl gallate(13), p-hydroxybenzaldehyde (14), 3 betahydroxybenzeneethanol( 15) ,and 2,4-dihydroxy-6-methoxy-acetophenone (16) on the basis of spectroscopic data analysis. All the compounds are isolated from this plant for the first time, and compounds 1, 4-8, 15 are obtained from Euphorbia species for the first time.
