目的:建立肺毒清处方中有效成分的含量测定方法,并考察其含量与转移率的相关性。方法:按不同方法计算药材中有效成分的含量和提取转移率,包括取过筛后药材细粉测定和根据过筛药材细粉及未过筛后纤维中有效成分的含量及其在药材中所占比例,计算有效成分含量。结果:根据药材标准测得的有效成分含量不一定能真正反映其在药材中真实含量,并可能会影响有效成分的提取转移率。结论:计算药材中有效成分提取转移率时,应根据药材中有效成分的“真实含量”进行计算。
OBJECTIVE: To establish a method for the determination of the active ingredients in the formulation of Pifendin and investigate the correlation between the content and the metastasis rate. Methods: According to different methods to calculate the content of active ingredients in medicinal materials and extraction transfer rate, including the sieve after the determination of fine powder medicine and based on sieved powder and unscreened sieve after the active ingredient content of the fiber in the herbs Proportion, calculate the active ingredient content. Results: The content of active ingredients measured according to the standard of medicinal materials may not really reflect the true content in medicinal materials, and may affect the extraction and transfer rate of active ingredients. Conclusion: When calculating the extraction rate of active ingredients in medicinal materials, the calculation should be based on the “true content” of active ingredients in medicinal materials.
