Abstract:
Objective: Based on the advantages of representation of herb components group clustering by characteristic spectrum integrity, to study the in vitro dissolution behavior of Daidai Flavones Dropping Pills (DFDP), and to evaluate the synchronization release situation of group clustering. Methods: Rotating basket method and HPLC characteristic spectrum were employed to evaluate the group clustering dissolution and the release characteristics of DFDP in different dissolution media (pH 1.2 hydrochloric acid solution, pH 4.5 acetic acid-sodium acetate buffer, pH 6.8 phosphate buffer, and distilled water). The single exponential, logarithmic distribution and Weibull equation model were applied to fit the dissolution curves. Results: The similarity factor (f2) of the dissolution curves of nine common peak components in characteristic spectrum of DFDP was over 50; In addition the f2 of neohesperidin and naringin was 94.86, which indicated that the group clustering of DFDP had similar dissolution curves and synchronization release characteristics. Meanwhile the dissolution mechanism of group clustering of nine common peak activity composition was following the Weibull equation model. Conclusion: The established method is simple, rapid, and stable, which provides an experimental basic for in vitro analysis and quality evaluation of DFDP.
