But there are more influences on AOC measuring value of pure water quality and determination time. It is suggested that the pure water with unified standard can be applied within laboratory scale. It is advanced the 90 minutes determination RLU in order to shorten determination time. 但是纯水质量及检测时间对AOC测定值影响较大,建议各实验室采用统一标准的纯水,并提出90min测定光强,以便最大限度缩短检测时间。
METHODS : To adopt the technique of water extraction to make the granules of pure chinese traditional medicine, the identification, extractive determination and clinical application were finished. 方法:采用水提法制成纯中药冲剂,对其进行鉴别,浸出物测定和临床应用。
