Abstract

OBJECTIVE

To study the chemical constituents of Lysidice brevicalyx.

METHOD

Various chromatographic techniques were used to isolate and purify the constituents such as column chromatography on silica gel, Rp-silica gel, Sephadex LH-20 and HPLC. The structures were elucidated by chemical evidence and spectroscopic methods.

RESULT

Seven compounds were isolated from the 95% ethanol extract of the leaves of L. brevicalyx and these compounds were elucidated as 2-0-[1-(3-methylbutyryl)phloroglucin-ol]-beta-D-glucopynanoside (1), 3-beta-D-glucopyranosyloxy-4, 5-dimethoxy-benzoic acid (2), benzyl alcohol O-beta-D-glucopyra noside (3), polydatin (4), quercetin-3-alpha-L-rhamnopyranoside (5), ethyl gallate (6), benzyl 6-O-alpha-L-arabinofurano syl-beta-D-glucopynanoside (7).

CONCLUSION

All Compounds were isolated from this plant for the first time. Compounds 2, 3, 5-7 were obtained from this genus for the first time.

摘要

目的

研究短萼仪花的化学成分。

方法

采用多种色谱技术进行分离纯化，如硅胶柱色谱、反相硅胶柱色谱、葡聚糖凝胶LH - 20柱色谱及高效液相色谱等。通过化学方法和光谱手段鉴定结构。

结果

从短萼仪花叶的95%乙醇提取物中分离得到7个化合物，分别鉴定为2 - O - [1 - (3 - 甲基丁酰基)间苯三酚醇] - β - D - 葡萄糖苷(1)、3 - β - D - 吡喃葡萄糖氧基 - 4,5 - 二甲氧基苯甲酸(2)、苄醇O - β - D - 吡喃葡萄糖苷(3)、白藜芦醇苷(4)、槲皮素 - 3 - α - L - 鼠李糖苷(5)、没食子酸乙酯(6)、苄基6 - O - α - L - 阿拉伯呋喃糖基 - β - D - 吡喃葡萄糖苷(7)。
