【摘要】 目的优选桂枝甘草汤方药成分提取时药材的最佳组合方式。方法将方药分成混煎组和桂枝、甘草单煎混合组,用半仿生提取法提取,提取液作甘草次酸、肉桂酸、总黄酮、挥发油、干浸膏的含量测定及50%乙醇精制液的HPLC指纹图谱比较。结果除干浸膏2种组合提取液含量相近外,其余4个指标成分含量混煎液均明显高于单煎混合液;2种组合提取液的HPLC指纹图谱无明显差异;HPLC梯度洗脱总积分面积及主要特征峰峰面积:混煎液>单煎混合液。结论桂枝甘草汤方药成分提取时以桂枝与甘草混煎为佳。更多还原

【Abstract】 Objective To optimize the best ingredients combination of Guizhi Gancao Decoction. Method The prescription was put into two groups, and extracting by semi-bionic extraction. The contents of Glycyrrhetinic acid, Cinnamic acid, total flavones, volatile oil and dry extract in the each extract were determined, and HPLC fingerprint of the refined by 50% ethanol was compared. Results Except the similar content of dry extract in two kinds of combinations, the other four index components in mixed extract is significantly higher than individual extraction. Two kinds of combinations extract fingerprints of the HPLC had no significant difference. HPLC gradients eluting total score area and main characteristic peak area in mixed extract were higher than individual extraction. Conclusion It is better that Guizhi Gancao Decoction extracted with Guizhi and Gancao mixed.更多还原
