气相色谱法测定红景天属植物中红景天甙及百脉根甙的含量

Quantitative Analysis of Salidroside and Lotaustralin in Rhodiola by Gas Chromatography

采用硅醚化方法，用甘露醇丙酰化物作内标物，建立了红景天植物药材中红景天甙和百脉根甙的气相测定方法。测定了青海省产１０种红景天共１９个样品。红景天甙和百脉根甙的回收率分别为１００．０５％，９７．８５％。

The contents of salidroside and lotaustralin in 10 species of Rhodiola genus were determined by GC method with propionylated mannitol as internal standard compound under the condition of silylation with hexamethyl disilazane:trimethyl chlorosiland (2∶1).The recoveries are 100.05% (salidroside) and 97.85% (lotaustralin).
