珠子参饮片质量标准研究

Quality standard for prepared pieces of Rhizoma Panacis Majoris

目的:建立珠子参饮片质量标准。方法:采用性状、显微、TLC进行定性鉴别,高效液相色谱法测定人参皂苷Ro、竹节参皂苷Ⅳa的含量。同时测定了水分、灰分和酸不溶性灰分等。结果:对四川、云南、贵州等省区所产珠子参饮片中人参皂苷Ro和竹节参皂苷Ⅳa的含量进行测定,结果显示,各样品中人参皂苷Ro平均含量为7.19%,竹节参皂苷Ⅳa的平均含量为3.16%。结论:本法操作简便、稳定性好,可用于珠子参饮片中人参皂苷Ro和竹节参皂苷Ⅳa的含量测定;制定的质量标准规范,结果准确。

AIM： To establish quality standard for prepared pieces of Rhizoma Panacis Majoris. METHODS： Traditional identification and TLC were used for qualitative analysis of prepared pieces. The contents of ginsenoside Ro and chikusetsusaponin IVa were determined by HPLC. Water,ash and acid-insoluble ash were also detected. RESULTS： The average content of ginsenoside Ro was 7. 19% ,chikusetsusaponin IVa was 3. 16% from different habitants. CONCLUSION： The established method has been proved to be simple,stable,accurate,and can be applied to the determination of ginsenoside Ro and chikusetsusaponin IVa in Rhizoma Panacis Majoris. The quality control standards for Rhizoma Panacis Majoris is normative and the result is accurate.
