目的研究红毛丹Nephelium lappaceum果壳的化学成分。方法采用硅胶柱色谱与Sephadex LH-20凝胶柱色谱进行分离纯化,并运用波谱方法对分离的化合物进行结构鉴定。结果从红毛丹果壳醋酸乙酯提取物中分离鉴定了14个化合物,经波谱解析鉴定为邻苯二酚(1)、4-甲氧基甲苯(2)、没食子酸乙酯(3)、3-(3,4-二甲氧基苯基)-2-丙烯醛(4)、异莨菪亭(5)、麦角甾醇(6)、滨藜叶分药花苷(7)、常春藤皂苷元(8)、二氢山柰酚(9)、山柰酚(10)、kaempferol-3-β-D-(6-O-trans-p-coumaroyl)-glucopyranoside(11)、山柰酚-3-α-L-吡喃鼠李糖苷(12)、山柰酚-3-O-(6-O-咖啡酰基)-β-D-吡喃葡萄糖苷(13)、β-谷甾醇(14)。结论所有化合物均为首次从红毛丹果壳中分离得到。
Objective To study the chemical constituents of Nephelium lappaceum husk. Methods The compounds were separated and purified by silica gel column chromatography and Sephadex LH-20 gel column chromatography. The structures of the isolated compounds were identified by spectroscopic methods. Results Fourteen compounds were isolated and identified from the ethyl acetate extracts of rambutan husk and identified as catechol (1), 4-methoxytoluene (2) and ethyl gallate (3) by spectral analysis. (4), scopolamine (5), ergosterol (6), Atriplex (7), ivy (11), kaempferol (8), dihydro-kaempferol (9), kaempferol (10), kaempferol-3-β-D- (6-O-trans-p-coumaroyl) (12), kaempferol-3-O- (6-O-caffeoyl) -β-D-glucopyranoside (13), β-sitosterol 14). Conclusion All the compounds were isolated from the rape shell for the first time.
