从白粉藤(Cissus repensLank)地上部分分离得到5个木脂素和8个三萜,其中一个木脂素是新化合物,它的结构通过波谱分析和碱水解的方法鉴定为:(+)-异落叶松树脂醇-9′-(2-对-香豆酰)-O-β-D-吡喃木糖苷(1)。其余化合物分别是:(+)-异落叶松树脂醇-9′-O-β-D-吡喃木糖苷(2),(+)-Lyoniside(3),(─)-开环异落叶松树脂醇-9-O-β-D-吡喃木糖苷(4),(7′R,8′S)-4′-hydroxy-3′,5-dimethoxy-7′,8′-dihydro-benzofuran-1-propanolneolignan-9′-O-β-D-xylopyranoside(5),木栓酮(6),表木栓醇(7),蒲公英赛醇乙酸酯(8),熊果酸(9),2α-羟基乌索酸(10),积雪草酸(11),Niga-ichigoside F1(12),羽扇豆醇(13)。这些化合物都是首次从该植物中分离得到。
Five lignans and eight triterpenoids were isolated from aerial parts of Cissus repens Lank. One of the lignans was a new compound. Its structure was identified by spectral analysis and alkaline hydrolysis: (+)- Larch resin alcohol-9′-(2-p-coumaryl)-O-β-D-xylopyranoside (1). The remaining compounds are: (+)-Isevera larch resin alcohol-9’-O-β-D-xylopyranoside (2), (+)-Lyoniside (3), (-)-open ring larch Resin alcohol-9-O-β-D-xylopyranoside (4), (7′R,8′S)-4′-hydroxy-3′,5-dimethoxy-7′,8′-dihydro-benzofuran 1-propanolneolignan-9′-O-β-D-xylopyranoside (5), thromboxane (6), epiphen alcohol (7), dandelion acetate (8), ursolic acid (9) , 2α-hydroxyuronic acid (10), Asiatic acid (11), Niga-ichigoside F1 (12), lupeol (13). These compounds were isolated from the plant for the first time.
