Study on Optimal Extract Technology of Anmai Granules by Orthogonal Test / 中国中医药信息杂志

Objective To optimize the extraction procedure for Anmai Granules. Methods With the content of Chlorogenic acid and Cinnamylic acid as indexes, orthogonal table L9(34) was used in the experiment of extracting in alcohol to study the effect of technological parameters (the concentration and dosage of alcohol, extraction times, the time of extraction) on the content of Chlorogenic acid and Cinnamylic acid. Results The optimum process is that 70% alcohol is used as extracting solution adding 9 times amount of solution, extracting 2 times, 1.0 hours for each time. Conclusion The extraction process is stable and suitable for industrial production.
