摘要:
采用高效液相色谱法(HPLC),对桂林产的白花丹茎中不同月份的白花丹醌含量进行了测定。结果表明:在流动相为甲醇水(70∶30),检测波长为254 nm的条件下,白花丹醌在0.00048~0.0240 mg·mL1之间线性关系良好;回收率为96.9%~100.0%,白花丹茎中白花丹醌含量10月份最高,这时也是白花丹茎生物产量的高峰期,说明10月份是白花丹茎的最佳采收期。
Abstract:
The plumbagin content in stems of Plumbago zeylanica was determined during different months in Guilin,China,using RPHPLC,methanol and H2O (70∶30) as mobile phase and UV detection at 254 nm. Linear range over 0.00048-00240 mg·mL1 of plumbagin was obtained. Recovery rate was within 969%-1000%. The content in stems of P.zeylanica was the highest in October when the plant was the most thriving and biggest in size. It was therefore considered that October was the best time for collecting stems.
