The factors influencing the alcohol percolation were as follows: A>B>C (A: the amount of alcohol added. B: the alcohol concentration. C: the percolation time). The optimum percolation condition obtained was: adding 5 fold of alcohol which concentration was 60%, and percolating for 48 hours.

Results: The factors influencing the alcohol-percolation were as follows: A>B>C (A: the amount of alcohol added. B: the percolation time.C:the alcohol concentration). The optimum percolation condition obtained was: 48-fold of 80% alcohol, being added and percolating for 24 hours.

Objective: To optimize the preparation process of Guhuan Capsules. Methods: The optimum extraction conditions were studied by the orthogonal test in baicalin & berberine as markers. Results: Radix Notogiseng was crushed to powder (120 mesh) and added directly into capsules. The factors influencing the alcohol percolation were as follows: A>B>C (A: the amount of alcohol added. B: the alcohol concentration. C: the percolation time). The optimum percolation condition obtained was: adding 5 fold of...

The factors influencing decoctation were as follows: A>C>B>D (A:the amount of water added. B: the alcohol concentration in the fluidextract of herbs. C: decoction time, D: decoction times). The optimum decoction condition obtained was: adding water (12 times as much as medicine), decocting twice 1.5 hours each time, merging the filtrate, concentrating the merged filtrate into extract with a relative density of 1.20 (measured at 85℃), then adding alcohol slowly, and making the concentration of alcohol in the fluidextract come to 80%. Conclusion: The optimized process is stable and feasible.

The optimum percolation condition obtained was: 48-fold of 80% alcohol, being added and percolating for 24 hours. The optimum conditions of granulation by sprayer were that the fluid extract was 1.5 times of Dextrin in weight; the relative density of the fluid extract was 1.20(measured at 25℃), the voltage of sprayer was 80 volts, the period of bag shaking was 65 (shaking bag back and forth twice in each period). Conclusion: The results of the experiment show that the preparation process of XueMaiNing Granule is stable and applicable.

Objective:To optimize the extraction of the total anthraquinone of rhubarb. Methods:Taking content of emodin as parameters. The optimum extraction process was selected with the L9(34) orthogonal design. Results:The significant effects of alcohol concentration, alcohol volume and percolation time on the extraction of emodin content were discovered. Conclusion:The optimum rhubarb percolation condition obtained was:adding 8-fold times of 55% alcohol and percolating for 9 hours. Emodin content ≥2.60%....
