对野生何首乌块根(野生品)与栽培何首乌块根(栽培品)中的总蒽醌(Ⅰ)、游离蒽醌(Ⅱ)、结合蒽醌(Ⅲ)、二苯乙烯苷(Ⅳ)、磷脂(Ⅴ)、金属元素(Ⅵ)的含量进行了测定,并对二者的醇提物质进行了薄层层析比较。结果表明,野生品与栽培品中Ⅰ、Ⅱ、Ⅲ和Ⅳ的含量基本相同,栽培品中Ⅳ和Ⅴ的含量稍低于野生品,栽培何首乌基本可以代替野生何首乌药用;并应注意药材的采收期。

[Abstract]
The effective components,total anthraquinones (Ⅰ),free anthraquinones (Ⅱ),bonded an thraquinones(Ⅲ), stilbenes (Ⅳ), phosphatides (Ⅴ) and meta1 elements (Ⅵ) in both wild Radix Polygonum multiflorum (WRPM) and the cultivated variety (CRPM) were determined.The alcohol extracts from WRPM and CRPM were compared by TLC. The results showed that their contents of Ⅰ, Ⅱ,Ⅲ and Ⅵ were similar to each other and so did their TLC graphs. Only the contents of Ⅳ and Ⅴ in CRPM were slightly less than those in WRPM. Thus,CRPM could be used instead of WRPM in clinical practices. On the other hand, the contents of all the substances varied with the time of collection.
