摘要
用反相高效液相色谱法测定藏药生等心材中墨沙酮的含量。浸泡和超声提取相结合，ＯＤＳ柱，甲醇水（２８∶７２），内含００５ｍｏｌ／Ｌ磷酸二氢钾（ｐＨ４）为流动相，ＵＶ２９０ｎｍ检测。回收率为９８９％。墨沙酮含量为１０２％。
A reversed phase HPLC method was developed for the determination of maesopsin, a fiavonoid, in the xylem parts of the traditional Tibetan medicinal herb Shengdeng (Rhamnella gilgitica). An ODS column was used and the mobile phase was methanol water (28∶27) with 0.05 mol/L KH 2PO 4(pH4). The detection wavelength was UV 290nm. The recovery was 98.9% (RSD=2.1%,n=6) and the content of maesopsin in Shengdeng was 1.02% (RSD=0.52%,n=3).
