海南国产沉香的化学成分研究

Study on the Chemical Constituents from Chinese Eaglewood in Hainan

摘要:

从国产沉香(Aquilaria sinensis)的95%乙醇提取物中分离得到6个化合物，经波谱数据分析，分别鉴定为3,3´-(3-hydroxypropane-1,2-diyl)diphenol (1)、guaiacylacetone (2)、6-羟基-2-(4´-羟基-2-苯乙基)色酮 (3)、6-羟基-2-(2-羟基-2-苯乙基)色酮 (4)、6-羟基-2-(2-苯乙基)色酮 (5)和5α,6β,7α,8β-四羟基-2-(4´-甲氧基-2-苯乙基)-5,6,7,8-四氢色酮 (6)。其中化合物1为新化合物，化合物3为首次从国产沉香中分离得到。

Abstract:

Six compounds were isolated from the 95% ethanol extract of Chinese eaglewood (Aquilaria sinensis). On the basis of spectroscopic data (NMR, MS, etc), they were identified as 3,3´-(3-hydroxypropane-1,2-diyl)diphenol (1), guaiacylacetone (2), 6-hydroxy-2-[2-(4-hydroxy-phenyl)ethyl]chromone (3), 6-hydroxy-2-(2-hydroxy-2-phenylethyl)chromone (4), 6-hydroxy-2-(2-phenethyl)chromone (5), and 5α,6β,7α,8β-tetrahydroxy-2-[2-(4-methoxy-phenyl)ethyl]- 5,6,7,8-tetrahydrochromone (6). Among them, compound 1 was a new compound and compound 3 was isolated from Chinese eaglewood for the first time.
