布渣叶中三萜和黄酮类成分的研究

Triterpenoids and Flavonoids from the Leaves of Microcos paniculata

摘要:

从布渣(Microcos paniculata L.)叶中分离得到10个化合物。通过光谱和波谱分析，分别鉴定为无羁萜(1)、阿江榄仁树葡糖苷Ⅱ(2)、山柰酚-3-O-β-D-[3,6-二-(对羟基桂皮酰)]-葡萄糖苷(3)、山柰酚-3-O-β-D-葡萄糖苷(4)、异鼠李素3-O-β-D-葡萄糖苷(5)、异鼠李素3-O-β-D-芸香糖苷(6)、牡荆苷(7)、佛来心苷(8)、异佛来心苷(9)、异牡荆苷(10)。10个化合物均为首次从布渣叶中分离得到。

Abstract:

Ten compounds were isolated from the leaves of Microcos paniculata L. On the basis of spectral data, they were identified as friedelin (1), arjunglucosideⅡ (2), kaempferol-3-O-β-D-[3,6-di-(p-hydroxycinnamoyl)]-glucopyranoside (3), kaempferol-3-O-b-D- glucopyranoside (4), isorhamnetin-3-O-β-D-glucopyranoside (5), narcissin (6), vitexin (7), violanthin (8), isoviolanthin (9) and isovitexin (10). All these compounds were obtained from this plant for the first time.
