ABSTRACT
OBJECTIVE:To establish a method for the rapid identification of Xiangsha pingwei pill(watered pill)from different manufacturers. METHODS:Near-infared spectroscopic method was conducted to collect the infrared spectroscopy of 95 batches of Xiangsha pingwei pill(watered pill) from 5 manufacturers,first derivative was combined with vector normalization to analyze the spectral data,mathematical models were established and validated. RESULTS:When the CI value was 5.6,the established model can identify samples from Li Shizhen Pharmaceutical Group Co.,Ltd. quickly,the model was validated to be achievable;and when the CI value was 4.7,the established model can identify Samples from Jinma Pharmaceutical Co.,Ltd. in Shangqiu city quickly, the model was validated to be achievable. CONCLUSIONS:The method is convenient,rapid and non-destructive,and can identify different Xiangsha pingwei pill(watered pill)from different manufacturers quickly.
ABSTRACT
OBJECTIVE: To develop a new form named dropping core pills which contain both water soluble and liposoluble constituents of the traditional Chinese medicine compounds. METHODS: Volatile, liposoluble and water-soluble constituents were extracted with supercritical fluid extraction-CO2,ethanol extraction, water decoction and membrane separation and other methods respectively. The dropping core pills were prepared with liposoluble and volatile constituents before being coated with water-soluble constituent. RESULTS: As compared with watered pills and dropping pills, dropping core pills had the advantages of both but overcome their shortages in that the dosage form was optimized, the amount of the reagent less and the resolving time was shorter. CONCLUSION: Dropping core pill was a new dosage form suitable for traditional Chinese Medicine compounds in which liposoluble and water-soluble components were both active compounds.
