摘要
目的:考察道地产区不同品种怀地黄中梓醇及毛蕊花糖苷的含量。方法:采用高效液相色谱法,甲醇回流提取梓醇及毛蕊花糖苷,Dikma Diamonsil C18色谱柱(4.6 mm×250 mm,5μm),流速1.0 mL.min-1,柱温30℃,梓醇流动相为乙腈-0.1%磷酸(1∶99),检测波长210 nm,毛蕊花糖苷流动相为乙腈-0.1%醋酸(16∶84),检测波长334 nm。结果:道地产区不同品种怀地黄中梓醇及毛蕊花糖苷含量不同,鲜地黄与生地黄中梓醇及毛蕊花糖苷的含量也不相同。结论:怀地黄品种品质不一,有必要进行种质资源优选。
Objective: To investigate the content of catalpol and acteoside in Rehmannia glutinosa with different varieties from genuine producing area. Method: Catalpol and acteoside were reflux extraction with methanol and determined by HPLC. The chromatographic column was Dikma Diamonsil C18 (4.6 mm × 250 mm, 5 μm) ; the flow rate was 1.0 mL .min-2 ; the column temperature was kept at 30 ℃ ; the mobile phase consisted of aeetonitrile-0. 1% phosphoric acid solution (1:99) and the detection wavelength was set at 210 nm for catalpol; the mobiles phase consisted of acetonitrile-0. 1% acetic acid solution (16:84) and the detection wavelength was set at 334 nm for acteoside. Result: The content of catalpol and acteoside was different in different varieties from genuine producing area and the differences also exist in the fresh and dried R. glutinosa. Conclusion: The quality of varieties of R. glutinosa was different and it was necessary to screen the optimal variety.
