Abstract
Nineteen compounds were isolated from the 95 % EtOH extract of the whole plants of Porandra scandens for the first time. On the basis of spectral data or by comparison with authentic samples,they were identified as(2S,3S,4R)-2-[ (2R)-2-hydroxyheneicosanoylamino]- 1,3,4-cheneicosanetriol(1), ( 2 S, 3 S, 4 R)-2-tetracosanoylamino- 1,3,4- octadecanetriol (2), daucosterol(3), β-sitosterol(4), (20S, 22E, 24R )-5α, 8α-epidioxy-ergosta-6,22-diene-3β-ol (5), 6β-hydroxystigmast- 4-en-3-one ( 6 ), 2,3-dihydroxypropyl hexadecoate( 7 ), betulinic acid (8), emodin (9), 2,3-dihydroxypropyl docosoate ( 10 ), p-hydroxybenzaldehyde( 11 ) ,2,3-dihydroxypropyl heptadecoate(12), aurantiamide acetate(13 ), 2,3-dihydroxypropyl nonadecoate ( 14 ), palmatic acid (15), (E) -p-coumaric acid ( 16 ), (22E, 24 S)-24-methyl-5α-cholesta-7,22-diene-3β, 5α, 6β-triol (17), 2-deoxycrustecdysone(18), and auranamide(19).关键词
