Abstract: Objective: To study the correlation among the spectra-effect relationship of HPLC spectrums of ethanol extracts and their
polar parts of Geranium strictipes and their anti-inflammatory activities in vivo, and explore the material basis of the anti-inflammatory
activity of Geranium strictipes. Methods: The HPLC spectrums of different parts of Geranium strictipes were established. The anti-
inflammatory activities of different parts of Geranium strictipes were determined by xylene-induced mouse ear swelling method. The
spectral-effect correlation between HPLC characteristic peaks of different parts and their anti-inflammatory effects was analyzed by
bivariate correlation analysis and partial least squares regression analysis. Results: Different parts of Geranium strictipes all exhibited
anti-inflammatory effects in which the ethyl acetate part worked best. The 27 characteristic chromatographic peaks in the HPLC
spectrums were selected, and 13 peaks were significantly correlated with the anti-inflammatory rate, the peaks ranked as No. 1(gallic
acid), 2(methyl gallate), 3(catechin), 8, 11, 13, 15, 17, 19(pentagalloylglucose), 20, 21, 25 and 27. Conclusion: The anti-
inflammatory activity of Geranium strictipes is the result of the coaction of multiple components.
