Abstract
Objective: To establish the quality standard of iridoid glycosides capsule of Lamiophlomis rotata(IGC). Method: The iridoid glycosides capsule of L. rotata was identified by TLC. The contents of total iridoid glycosides,shanzhiside methyl ester and 8-O-acetylshanzhiside methyl ester in the capsule were determined by the first derivating UV-spectra and HPLC. Result: The identify spots were clear in TLC,and the constituents were well separated under the chromatographic condition. The contents of total iridoid glycosides of three batch capsule were more than 50%,the shanzhiside methyl ester and 8-O-acetylshanzhiside methyl ester were separated with other composition and the content were 73. 96,72. 43 mg·g- 1respectively. Conclusion: The method can be used to control the quality of IGC.
