木麻黄根乙酸乙酯部位化学成分研究

Chemical Constituents of Ethyl Acetate Extract of Casuarina equisetifolia Roots

摘要:

为阐明木麻黄（Casuarina equisetifolia）的化学成分，采用有机溶剂提取、萃取及多种分离技术，从其根中分离得到14个化合物。经光波谱分析，其结构分别鉴定为5-hydroxy-3-methoxyphenyl-6-O-syringoyl-β-d-glucopyranoside （1），高良姜苷A （2），heterophylloside C （3）、6'-O-vanilloylisotachioside （4）、3，4，5-trimethoxyphenyl-6-O-syringoyl-β-d-glucopyranoside （5）、香草醛（6）、丁香醛（7）、3，4-二羟基苯甲醛（8）、齐墩果酸（9）、桦木酸（10）、胡萝卜苷（11）、胡萝卜苷亚油酸酯（12）、（±）-lyoniresinol 2-O-a-rhamnoside （13）和（-）-9-acetyl-isolariciresinol 9'-O-a-l-rhamnopyranoside （14），其中化合物14为新的木脂素。

Abstract:

To clarify the chemical constituents in Casuarina equisetifolia, fourteen compounds were isolated by organic solvent extraction, fractionation, and a variety of chromatographic separation techniques. Based on spectroscopic data, their structures were identified as 5-hydroxy-3-methoxyphenyl-6-O-syringoyl-β-d-glucopy-ranoside (1), alpinoside A (2), heterophylloside C (3), 6''-O-vanilloylisotachioside (4), 3,4,5-trimethoxyphenyl-6-O-syringoyl-β-d-glucopyranoside (5), vanillin (6), syringaldehyde (7), 3,4-dihydroxybenzaldehyde (8), oleanolic acid (9), betulinic acid (10), β-sitosterol glucoside (11), daucosterol-6'-linoleate (12), (±)-lyoniresinol 2-O-a-rham-noside (13), and (-)-9-acetyl-isolariciresinol 9'-O-a-l-rhamnopyranoside (14). Among them, compound 14 is a new lignan derivative.
