Research on preparation technology for Sini Boiling Powder / 中草药

ABSTRACT

Objective: To optimize the extracting process for Sini Boiling Powder at the condition of optimum particle size. Methods: The optimum size of particle was prepared, HPLC method was used for the determination of the content of ammonium glycyrrhetate and UV spectrophotometry was used for the determination of the content of total alkaloids. The decoction process was optimized by single factor test with boiling time, amount of water, and boiling times as factors. Then compared with traditional decoction, we can have a basis on clinic. Results: The optimal conditions of decoction process were soaking 20 min,14-fold water, boiling 30 min, once. The results showed that both the yield of dry extract and the content of active ingredient at different time points from the boiling powder granule were greatly more then its traditional one during the whole decoction process, and it suggested that Sini Boiling Powder is more safe then Sini traditional decoction. Conclusion: The advantage of high decoction rate and short preparing time on boiling powder can solve the problems that the traditional Chinese medicine is currently facing and should not be ignored.
