OBJECTIVE: To prepare Chang Bi Qing pellets. METHODS: By means of orthogonal design, the influence offollowing factors on quality of Chang Bi Qing pellets (CBQ) was studied: the ratio of extract of ingredients of CBQ with microcrystalline cellulose(as matrix ), the concentration of alcohol(as wetting agent ), the concentration of polyvinyl pyrrolidone(ascementing agent) and agitation time. RESULTS: The optimun preparing technology of CBQ was that the proportion of CBQextract to matrix was 2 to I and the con...
