摘要
采用RP-HPLC方法研究不同生长年份的栽培何首乌药用部位中蒽醌类物质的动态变化规律,来确定何首乌的最佳采收年份,为青海栽培何首乌作为药用提供科学依据。试验结果表明:不同采收年份的栽培何首乌药材中蒽醌类物质以8年生的含量最高。
RP-HPLC method was used to study the yearly dynamic variation of anthraquinones contents in Polygonum multiflorum collected by its growth time in Qinghai, and deciding optimum harvesting time. Meanwhile ,it can offer scientific foundation. The results showed that the total contents of anthraquinones in eight-year-old Polygonum multiflorum cultivated in Qinghai were the highest. The Polygonum multiflorum cultivated in Qinghai could take place of the wild one as useful medical plant, and the time for which a cultivated Polygonum multiflorum had grown could be Preliminarily determinated by the contents of anthraquinones.
