摘要
研究了人工种植的大花红景天醇提物的化学成分。采用溶剂法和柱色谱法分离纯化,通过波谱分析鉴定其化合物的结构。结果表明,从70%乙醇提取物中分离得到4个化合物,分别鉴定为3,5,7,8-四羟基-黄酮4′-氧-α-L-鼠李糖吡喃甙(1)、草质素-7-0-(3''-0-β-D-葡萄糖基)-α-L-鼠李糖苷(2)、酪醇(3)、红景天苷(4)。而且化合物Ⅰ为首次从该种植物中分离得到。人工种植的大花红景天其主要成分与野生相同,药材质量与野生的相似.可以相互替代使用。
The chemical constituents of the ethanol extracts of an artificial planted herb, Rhodiola Crenulata.H were studied. The chemical constituents were isolated and purified by column chromatography and structurally elucidated by spectrum analysis. Results showed that four compounds were obtained and identified as 3,5,7,8 - tetrahydroxyl flavone 4′- O - α- L - rhamnopyranoside（1）, rhodiosin（2）, tyrosol（3）, and Salidroside（4）, among which compounds 1 was firstly isolated from this kind of plant. We may conclude that the main chemical constituents and the quality of the artificial planted Rhodiola Crenulata.H were similar to those of the wild.
