Study on dissolution of three active components in Shexiang Baoxin Pill / 中成药

ABSTRACT

AIM: To study the dissolution of ginsenoside Rb1,cinnamic acid and borneol in traditional Chinese medicine Shexiang Baoxin Pill(Moschus,extract of Radix et Rhizoma ginseng,Calculus Bovis artifactus,Cortex Cinnamomi,Styrax,Venenum Bufonis and Borneolum syntheticum). METHODS: The in vitro dissolution of active components in Shexiang Baoxin Pill was performed with paddle method. HPLC was used for determination of ginsenoside Rb1 and cinnamic acid,and GC for borneol. RESULTS: The analytic method above was easy to carry out,the requirement of the specificity,accuracy,precision and stability could meet the needs of experiment well; the dissolution time T50 and Td of ginsenoside Rb1,cinnamic acid and borneol were 30. 90,33. 79 min,29. 73, 37. 11 min and 42. 38,48. 51 min respectively. CONCLUSION: The dissolution rate of three active components from Shexiang Baoxin Pills was fast and the analytic methods established in this study could be used to evaluate the quality of the preparation.
