摘要:

目的:研究龙胆科(Gentianaceae)獐牙菜属狭叶獐牙菜(Swertia angustifolia Buch.)的化学成分。方法:采用硅胶柱层析
和Sephadex LH-20柱层析分离纯化化合物,依据理化性质和现代波谱技术进行结构鉴定。结果:从乙酸乙酯部分分离鉴定了
7个单体化合物,分别为香草酸(vanillic acid,1)、1,3,8-三羟基-5-甲氧基口山酮(1,3,8- trihydroxy-5-methoxy xanthone,2)、
5,7,4′-三羟基二氢黄酮(5,7,4′-trihydroxy flavanone,3)、1-羟基-3,5,6-三甲氧基口山酮(1-Hydroxy-3,5,6-trimethoxy xan?
thone,4)、3,4-二羟基苯甲酸甲酯(methy -3,4-dihydroxy-benzoate,5)、邻苯二甲酸二异丁酯(diisobutyl phthalate,6)、1,8-二羟
基-3,5-二甲氧基口山酮(methyl-bellidifolin,7)。结论:化合物1~7 均为首次从狭叶獐牙菜中分离得到。

Abstract:

Objective: To explore the chemical constituents of Swertia angustifolia Buch. Methods: Compounds were separated and
purified by silica gel and Sephadex LH- 20 column chromatography and their structures were elucidated on the basis of
physicochemical properties and spectral analysis. Results: Seven monomeric compounds were obtained from ethyl acetate extract of S.
angustifolia, which were characterized to be vanillic acid(1), 1,3,8-trihydroxy-5-methoxy xanthone(2), 5, 7, 4′-trihydroxy flavanone
(3), 1-Hydroxy-3, 5, 6-trimethoxy xanthone(4), methyl -3, 4-dihydroxy benzoate(5), diisobutyl-phthalate(6), methyl-bellidifolin
(7). Conclusion: All seven compounds were obtained from S. angusifolia for the first time .

Key words: Swertia angustifolia Buch. , chemical constituents, separation study
