摘要
通过对比10种红景天属植物气相色谱发现:蔗糖和峰A存在于所有19个样品中,且含量较高。而公认有效成分红景天甙,仅在5种植物中的含量高于0.3％。有5种植物中含有百脉根甙,以狭叶红景天中含量最高。红景天甙和百脉根甙的含量,随产地和种的差异变化较大。
The comparison of the components in 10 species of Rhodiola by GC method showed that sucrose and peak A, a unknown constituent, exist in all of 19 samples collected in the east area of Qinghai Province and in high quantities. However, salidroside, a known active component from the genus, is found from only 5 species with the quantity of more than 0. 3%. There are 5 plants containing lotaustralin, a known oral toxic compound, and with the highest quantity in the plant of Rh. kirilown. The content of the two compounds above varies as plants and habitats are different.
