-methylgallic acid. 9-(β- d -Glucopyranosyloxy)-tetrahydroalstonine, (+)-5,5′- dimethoxy -9-O- (β- d -glucopyranosyl)lariciresinol , (−)-2α-O- (β- d -glucopyranosyl)-lyoniresinol and 3-O-(β- d -glucopyranosyl )-5-O- methylgallic acid are described for the first time. Structural determination is based on spectroscopic studies and/or on comparison with authentic compounds. Some of the isolated substances
摘要 从 Tabernaemontana cymosa (= T.psychtrifolia) 的种子中分离出 17 种吲哚生物碱和 6 种木脂素糖苷,此外还有三酰甘油、9,12-十八碳二烯酸、羽扇豆醇、(+)-lyoniresinol、obtusifoliol 和 3-sweroside O-甲基没食子酸。9-(β-d-吡喃葡萄糖基氧基)-四氢黄酮,(+)-5,5'-二甲氧基-9-O-(β-d-吡喃葡萄糖基)落叶松树脂醇,(-)-2α-O-(β-d-吡喃葡萄糖基) )-lyoniresinol 和 3-O-(β-d-吡喃葡萄糖基)-5-O-甲基没食子酸是首次被描述。结构测定基于光谱研究和/或与真实化合物的比较。一些分离的物质表现出显着的抗真菌和/或细胞毒性作用。
