目的建立金牛七的质量控制标准。方法 从金牛七的性状、鉴别、检查及浸出物测定等方面进行研究。结果 金牛七的性状、鉴别特征明显;药材水分平均含量为9.40%;总灰分、酸不溶性灰分平均含量分别为4.13%、0.68%;醇(40%乙醇)溶性浸出物平均含量为27.47%。结论 从性状、鉴别、检查及浸出物测定等方面可以有效控制金牛七的质量,该研究为金牛七的质量标准制订提供了依据。
Objective To establish Jinniu seven quality control standards. Methods The traits, identification, examination and extraction of Jinniu 7 were studied. Results The traits and distinguishing characteristics of Jinniu 7 were obvious. The average content of water in herbs was 9.40%. The average contents of total ash and acid-insoluble ash were 4.13% and 0.68% respectively. The average content of alcohol (40% ethanol) soluble extract was 27.47%. Conclusion The quality of Jinniu 7 can be effectively controlled in traits such as traits, identification, examination and extract determination. The research provided the basis for Jinniu 7 quality standard formulation.
