炮制方法对巴戟天有效成分水晶兰苷含量的影响

目的:测定巴戟天炮制品中水晶兰苷的含量。方法:采用HPLC法。色谱条件:Krom alsil C18柱(150 mm×4.6 mm,5μm);甲醇-0.4%磷酸水溶液(5∶95→28.8∶71.2,15 min)为流动相;流速1 ml/min;检测波长231 nm;柱温25℃。结果:巴戟天不同炮制品中水晶兰苷含量与生品比较有较大差异,生巴戟天、巴戟肉、盐巴戟天、制巴戟天中水晶兰苷的平均含量分别为13.92 mg/g、9.10 mg/g、9.21 mg/g、12.86 mg/g。结论:不同炮制方法使巴戟天炮制前后水晶兰苷的含量发生改变。

Determination of Monotropein in Radix Morindae from Different Processed Products by HPLC

OBJECTIVE: To determine the contents of monotropein in the different processed Products of Radix Morindae. METHODS: Conditions: Kromasil C18 (150 mm x 4. 6 mm,5 micorm) column; The mobile phase was methol-0.4% phosphate solution (5:95-->28.8: 71.2, 15 min); The velocity of flow was 1 ml/min; The detection wavelength was at 210 nm; And column temperature was 25 degrees C RESULTS: There were obvious differences between the crude and kinds of different processed products of monotropein in the Radix Morindae, The contents of monotropein from the different processed products (crude drugs, removed from wood, processed with salt, prepared) were 13.92 mg/g,9.10 mg/g, 9.21 mg/g, 12.86 mg/g, respectively. CONCLUSION: The different processing methods can make the contents of monotropein in the Radix Morindae.
