摘要:

目的:研究番木瓜果肉的化学成分,寻找活性物质。方法:用85% 乙醇提取,大孔吸附树脂、ODS、MCI 柱层析进行分离,NMR 波谱法鉴定化合物的结构。结果:从番木瓜果肉乙醇提取物中分离到3 种化合物,分别为2β,3β - 二羟基- 乌苏酸(Ⅰ)、3-O- 葡萄糖- 甾苷(Ⅱ)、薯蓣皂苷元-3-O- β -D- 吡喃葡萄糖基(1 → 3)- β -D- 吡喃葡萄糖基(1 → 4)-[α -L- 吡喃鼠李糖基(1 → 2)]- β -D- 吡喃葡萄糖苷(Ⅲ)。

Abstract:

Objectives: To investigate bioactive compounds from Carica papaya pulp. Methods: Chemical components in Carica papaya pulp was extracted using 85% ethanol and purified by marcoporous resin adsorption followed by ODS and MCI column chromatography. The structures of these compounds were elucidated through NMR spectroscopic analysis. Results: Three compounds were isolated from Carica papaya pulp and their chemical structures were identified as 2β, 3β-dihydroxy-ursolic acid (Ⅰ); 3-O-glycoside-sterol (II); diosgenin-3-O- β-D-glucopyranosyl(1 → 3)- β-D-glucopyranosyl(1 → 4)-[α-Lrhamnopyranosyl(1 → 2)]- β -D-glucopyranoside (III), respectively. Conclusion: To the best of our knowledge, this paper is the first one that reports compounds I - III obtained from Carica papaya pulp.

Key words: Carica papaya, isolation, ursolic acid, glycoside-sterol, steroidal saponin
