Studies on extracting factors of Bushenjiangu Capsule / 中成药

ABSTRACT

Objective: To study the optimum extracting factors of Bushenjiangu Capsule. Methods: Uniform Design was used to arrange experiments, Ursolic acid content was used to evaluate the factor levels, and the optimum extracting factors were determined according experiments and realities. The orthogonal design was used to study three factors including crude drug size extracting time and amount of water. water extracted rate and alcohol extracted substance were used to evaluate the result. Results: The optimum alcohol-extracting factors were 8 times of 70% alcohol, percatating 48 hours. The optimum water-extracting factors were 1cm or smaller the crude drug size, boiling 3 times 3h,2h,1h, each time, the amount of water was 10,8,6 times. Conclusion: According the optimum extracting factors, the effective substance can be extracted abundantly.
