目的对细梗香草全草甲醇部分进行分离和化合物结构鉴定。方法通过大孔树脂纯化,Sephedax LH20和聚酰胺分离;利用多种波谱技术并结合酸水解方法鉴定其化学结构。结果分离鉴定了3个黄酮苷和1个三萜皂苷,分别为槲皮素-3-O-(2,6--αL-二吡喃鼠李糖基)-β-D-吡喃半乳糖苷(1),capilliposide I(2),capilliposideⅡ(3)和candidoside(4)。结论化合物4为首次从细梗香草中分离得到。 Objective To isolate and identify the structures of the methanol fractions from the herbaceous stems. Methods The macroporous resin was used to purify Sephidax LH20 and polyamide. The chemical structures were identified by several spectroscopic techniques combined with acid hydrolysis. Results Three flavonoid glycosides and one triterpene saponin were isolated and identified. They were quercetin-3-O-(2,6-αL-dipyrhamnosyl)-β-D-pyranogalactan. Glycosides (1), capilliposide I (2), capilliposide II (3) and candidoside (4). Conclusion Compound 4 was isolated for the first time from the fine-stemmed herbs.
