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254nm的条件下,白花丹醌在0.00048～0.0240mg.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。
The plumbagin content in stems of Plumbago zeylanica was determined during different months in Guilin, China,using RP-HPLC. methanol and H2O （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.
