摘要: 目的:研究番木瓜果肉的糖类成分,以寻找活性化合物。方法:干燥的番木瓜干经95%乙醇提取,石油醚萃取脱脂后的水相采用聚酰胺、MCI、ODS、ODS-AQ柱层析进行纯化,并通过MS和NMR鉴定。结果:从番木瓜果肉乙醇提取物中分离并鉴定出4个糖的衍生物,分别为乙基α-D-果糖苷(Ⅰ)、乙基β-D-果糖苷(Ⅱ)、苄基β-D-葡萄糖苷(Ⅲ)、2-O-β-D-葡萄糖苷-3,6-二羟乙基-5-苯基-1,4-二氧已基-2-醇(Ⅳ)。

关键词: 番木瓜, 果糖苷, 葡萄糖苷

Abstract: Objectives: To separate, purify and identify sacchrides in Carica papaya flesh. Methods: Dried Carica papaya flesh was subjected to 95% ethanol extraction, petroleum ether defatting, and sequential chromatographic separation on polyamide, MCI, ODS and ODS-AQ columns. Quantitative identification was carried out by MS and NMR. Results: Four compounds Ⅰ-Ⅳ were obtained and identified as ethylα-D-fructoside(Ⅰ), ethylβ-D-fructoside(Ⅱ), benzylβ-D-glucoside(Ⅲ), and 2-O-β-D-Glu-3,6-bis(hydroxythyl)-5-phenyl-1,4-dioxan-2-ol(Ⅳ), respectively.

Key words: Carica papaya, fructoside, glucoside
