Objective: The quality control method of "Lü Kang Yin Xing Ye Pian" (LKYXYP) was studied and established.
Method: The ginkgolides in LKYXYP were identified by TLC. The compounds of fatty acids in Perillae oil were determined by CC/MS. Flavones, ginkgolides and ginkgolic acids were determined by HPLC.
Result: There were good linears relationship between the peak area and concentration, r = 0.999, RSD = 1.2% - 2.5% (n = 5), and recoveries of each composition was above 95%, the contation was stable in 24h.
Conclusion: This method is proved to be accurate and able to be applied for the quality control of this preparation.
