摘要:

运用多种色谱法进行分离纯化,并通过理化性质和波谱数据对化合物进行结构鉴定,研究葫芦茶地上部分的化学成分。结果表明:从葫芦茶地上部分分离并鉴定了13个化合物,分别为山柰酚(1)、山柰酚-3-O-α-L-鼠李糖苷(2)、山柰酚-3-O-β-D-葡萄糖苷(3)、山柰酚-3-O-β-D-芸香糖苷(4)、槲皮素-3-O-α-L-鼠李糖苷(5)、山柰酚-3-O-α-L-鼠李糖(1→6)-β-D-半乳糖苷(6)、槲皮素-3-O-β-D-葡萄糖苷(7)、槲皮素-3-O-α-L-鼠李糖(1→6)-β-D-半乳糖苷(8)、芦丁(9)、间苯三酚-O-β-D-葡萄糖苷(10)、对羟基桂皮酸(11)、RoseosideⅡ(12)、儿茶素(13)。其中化合物2、4、5、6、8、9、10、12为首次从该植物中分离得到。

Abstract:

Compounds were separated by various chromatographic techniques to study the chemical constituents of the air part of Tadehagi trquetrum. Their structures were identified by analyzing their physicochemical properties and spectral data. The results showed that thirteen compounds were purified and determined as kaempferol(1),kaempferol-3-O-α-L-rhamnoside(2),kaempferol-3-O-β-D-glucoside(3),kaempferol-3-O-β-D-rutinoside(4),quercetin-3-O-α-L-rhamnoside(5),kaempferol-3-O-α-L-rhamnoside(1→6)-β-D-galactopyranoside(6),querceitin-3-O-β-D-glucopyranosi(7),quercetin-3-O-α-L-rhamnoside(1→6)-β-D-galactopyranoside(8),rutin(9),phloroglucinol-1-O-β-D-glucopyranoside(10),naringenic acid(11),roseosideⅡ(12),(+)-catechin(13). Compounds 2, 4, 5, 6, 8, 9, 10, 12 were isolated from Tadehagi trquetrum for the first time.
