基于标准汤剂的竹节参配方颗粒质量标准研究

Quality standard for Zhujieshen Formula Granules based on standard decoction

目的基于标准汤剂建立竹节参配方颗粒质量标准。方法HPLC法测定标准汤剂、配方颗粒中人参皂苷Ro、竹节参皂苷Ⅳa含量,计算转移率。建立标准汤剂HPLC特征图谱,并进行聚类分析、主成分分析。再建立配方颗粒HPLC特征图谱。结果17批标准汤剂HPLC特征图谱中有9个共有峰,相似度大于0.9(除S6、S12外),聚为2类,3种主成分累积方差贡献率达86.7%。3批配方颗粒中人参皂苷Ro含量为83.1~88.6 mg/g,转移率为53.1%~55.5%;竹节参皂苷Ⅳa含量为14.8~15.0 mg/g,转移率为47.4%~48.1%。3批配方颗粒HPLC特征图谱中有9个共有峰,相似度分别为0.998、0.998、0.999。结论该方法合理可靠,可全面评价竹节参配方颗粒质量,为其质量控制提供参考。

AIM To establish the quality standard of the zhujieshen Formula Granules based on standard decoction.METHODS The contents and transfer rates of ginsenoside Ro and chikusetsu saponinⅣa in standard decoction and formula granules were determined by HPLC,after which the transfer rates were calculated.The HPLC characteristic chromatograms of standard decoctions were established,after which cluster analysis and principal component analysis were adopted.Then the HPLC characteristic chromatograms of formula granules were established.RESULTS Nine common peaks were found in the HPLC characteristic chromatograms of seventeen batches of standard decoctions with the similarities of more than 0.9(except for S6,S12),which were clustered into two categories,and the accumulative variance contribution rate of three principal components reached 86.7%.The contents of ginsenoside Ro in three batches of formula granules were 83.1-88.6 mg/g,and the transfer rates were 53.1%-55.5%.The contents of chikusetsusaponinⅣa were 14.8-15.0 mg/g,and the transfer rates were 47.4%-48.1%.Nine common peaks were found in the HPLC characteristic chromatograms of three batches of formula granules with the similarities of 0.998,0.998 and 0.999,respectively.CONCLUSION This reasonable and reliable method can comprehensively evaluate the quality of Zhujieshen Formula Granules,and provide a reference for the quality control.
