摘要
目的 :研究中药白及极性部位的化学成分。 方法 :用多种层析方法分离正丁醇部分的萃取物 ,根据理化性质和波谱分析 ,鉴定化合物结构。 结果 :分离并鉴定 5个化合物结构 ,分别是 m ilitarine(1) ;7-羟基 - 4-甲氧基菲 - 2 -β- D-葡萄糖苷 (7- hy-droxy- 4- m ethoxyphenanthrene- 2 - O-β- D- glucoside) (2 ) ;4-甲氧基菲 - 2 ,7- O-β- D-二葡萄糖苷 (4 - methoxyphenanthrene- 2 - 7- O-β- D - diglucoside) (3) ;7-羟基 - 2 ,4-二甲氧基菲 - 3- O-β- D-葡萄糖苷 (7- hydroxy- 2 ,4- dimethoxyphenanthrene- 3- O-β- D- glucoside)(4 ) ;3′-羟基 - 5 -甲氧基联苄 - 3- O-β- D -吡喃葡萄糖苷 (3′- hydroxy- 5 - m ethoxybibenzyl- 3- O-β- D- glucopyranoside) (5 )。 结论 :化合物 1和 5首次从该植物中分离得到。
Objective:To study the polar chemical constituents of Blettila striata(Thunb.) Reichb.f. Methods:The constituents in N-butanol moiety were separated and purified by column chromatography with silica gel and SephadexLH-20, and were identified by spectral analysis. Results:Five compounds were identified as: militarine(1);7-hydroxy-4-methoxy-phenanthrene-2-O-β-D-glucoside(2);4-methoxyphenanthrene-2,7-O-β-D-diglucoside(3);7-hydroxy-2,4-dimethoxyphenanthrene-3-O-glucoside(4);3′-hydroxy-5-methoxybibenzyl-3-O-β-glucopyranoside(5). Conclusion:Compound 1,5 were isolated from this plant for the first time.
