摘要 从墨西哥落羽杉(Taxodium mucronatum)枝叶中首次分离得到10个化合物,通过MS与NMR等方法将它们分别鉴定为quercetin 3′-methoxy-3-O-β-D-galactopyranoside(1),quercetin 3′-methoxy-3-O-β-D-arabinopyrano-side(2),quercetin 3′-methoxy-3-O-α-L-arabinofuranoside(3),quercetin(4),avicularin(5),quercetin 3-O-β-D-ga-lactopyranoside(6),(7′S,8′R)-4,7′-epoxy-3,3′-dimethoxy-4,9,3′,4′,9′-lignanepentol-4′-O-β-D-glucopyranoside(7),(7′S,8′S)-3,3′-dimethoxy-9,4′,9′-trihydroxy-4,8′-oxyneolignan-7′-O-β-D-glucopyranside(8),methyl shikimate(9)和β-sitosterol(10)。 Ten known compounds were isolated from the leaves and branches of Taxodium mucronatum for the first time. On the basis of MS and NMR data, they were identified as quercetin 3′-methoxy-3-O-β-D-galactopyranoside (1), quercetin 3′-methoxy-3-O-β-D-arabinopyranoside ( 2), quereetin 3′-methoxy-3-O-α-L-arabinofuranoside ( 3 ), quercetin ( 4 ), avieularin ( 5 ), quercetin 3 -O-β-D-galaetopyranoside ( 6 ), ( 7′S, 8′R) -4,7′-epoxy-3,3′-dimethoxy-4,9,3′, 4′, 9′-lignanepontol-4′-O-β-D-glucopyranoside (7), (7′S,8′S) -3,3′-dimethoxy-9,4′ ,9′-trihydroxy-4,8′-oxyneolignan-7′-O-β-D- glueopyranside (8), methyl shikimate (9) and β-sitosterol ( 10 ).
