摘要:

研究藏药狭叶红景天的化学成分, 应用硅胶、ODS和Sephadex LH-20 凝胶柱色谱以及反相HPLC等多种技术进行分离和纯化, 应用波谱技术确定化合物的结构。从藏药狭叶红景天乙醇提取物中分离鉴定了11个化合物, 其中4-羟基-苯乙基-(4'-甲氧基-苯乙基) 醚 (1) 和 β-D-葡萄糖苷-2-羟基-2-甲基-丁酸酯 (2)为新化合物; 对乙氧基苯乙醇乙酯 (3), 对羟基苯甲酸乙酯 (5), 对羟基苯甲醛 (7), R(-)-mellein (8), 对甲氧基苯乙醇 (10) 5个化合物为首次从红景天属植物中得到, 对羟基苯乙酮 (4), 对羟基苯甲酸 (6), 豆甾醇 (9), 3,4,5-三羟基苯甲酸甲酯 (11) 4个化合物为首次从狭叶红景天中得到。

Abstract:

Chemical constituents of the whole herb of Rhodiola kirilowii (Regl) Maxim. were investigated. The separation of the constituents was achieved by using a combination of various chromatographic techniques including column chromatography over silica gel, ODS, Sephadex LH-20 and reversed-phase HPLC. Their structures were elucidated by spectroscopic techniques including 1D and 2D NMR spectroscopy. Eleven compounds were obtained and identified as 4-[2-[(4-methoxyphenyl)ethoxy]ethyl]phenol (1), 1-(2-hydroxy-2-methylbutanoate)-β-D-glucopyranose (2), 4-ethoxy-phenylethanol acetate (3), p-hydroxyacetophenone (4), p-hydroxy-benzoic acid ethylester (5), 4-hydroxybenzoic acid (6), 4-hydroxybenzaldehyde (7), R(-)-mellein (8), stigmasterol (9), 4-methoxy-phenylethanol (10), and methylgallate (11). Among them, 1 and 2 are new compounds; compounds 3, 5, 7, 8, and 10 were isolated from Rhodiola genus for the first time; and compounds 4, 6, 9, and 11 were isolated from Rhodiola kirilowii (Reg1) Maxim. for the first time.
