ABSTRACT
Objective To study the preparing craft and quality control for Biyan Jiedu Granule. Methods Medicines of Biyan Jiedu Granule were prepared with traditional methods, then extracted by water, concentrated, and then mixed with adjuvant materials into granule. TLC was used to identify milkvetch root, baical skullcap root, and radix glycyrrhizae. Results The preparing method was simple and feasible. The quality of the product was stable. TLC could identify characteristic spots. Conclusion The preparation craft is simple and convenient for quality control, providing a practical and feasible method for producing Biyan Jiedu Granule.
ABSTRACT
Objective To study the influence of the preparation and quality control of Xiaochuan cataplasm on its drug action. Methods Xiaochuan cataplasm was prepared with hydrosoluble polymers matrix. A sequence of tests such as adhesive force test, recontour test, paste-content test, cold-resistance test, heat-resistance test, toxicity and pharmacodynamic action tests were performed on this drug. Results Xiaochuan cataplasm contains a sound volume of medicine, and shows good adhesive property, no sensibilization and stimulation, and notable drug action. Conclusion The results demonstrate that the preparation craft of Xiao-chuan cataplasm is reasonable and practicable., the quality is controllable and the method is a safe and effective transdermal drug delivery system.
