附子及其复方制剂中的总生物硷在pH4.3的缓冲液中与溴甲酚紫形成离子对,用二氯甲烷提取后可进行比色测定。结果准确重现性好。可作为复方参附注射液的质控指标。
The total bio-germanium in the aconite and its compound preparation forms an ion pair with bromocresol purple in pH 4.3 buffer, and can be determined colorimetrically after extraction with dichloromethane. The result is accurate and reproducible. It can be used as a quality control indicator for compound Shenfu injection.
