采用二氯甲烷：石油醚（３＋４）混合液浸泡，经高速分散器分散后离心提取，经ＰＴ—硅镁吸附剂型色谱预处理小柱净化，用岛津ＬＣ—５Ａ高效液相色谱仪测定。以甲醇、水（７５＋２５）为流动相，Ｃ１８反相柱为固定相，岛津ＳＰＤ—２ＡＭ紫外检测器在２５４．０ｎｍ波长...
The samples were soaked in a mixture of dichloromethane and petroleum ether (3 + 4), dispersed in a high-speed disperser, centrifuged, and purified by a PT-silica-magnesium adsorbent chromatographic pretreatment column and measured with a Shimadzu LC-5A high performance liquid chromatograph. Methanol, water (75 +25) as mobile phase, C18 reversed-phase column as the stationary phase, Shimadzu SPD-2AM UV detector at 254.0nm wavelength ...
