ObjectTo establish HPLC fingerprint for the identification and evaluation of Caulis Spatholobi. Methods HPLC system was used to obtain the chromatograms of Caulis Spatholobi and the clustering analysis was applied for data analysis. Results There are 11 peaks in total, among them five are common, the relative retention time is 0.046, 0.664, 1.000, 1.198, 1.383, the relative peak area is 0.819,0.221,1.000,0.331,0.458. There was obvious difference among chromatographic fingerprints of Caulis Spatholobi and its easily-confused species. The 11 measured peaks could be used as the fingerprint features. Conclusion Chromatographic fingerprint of HPLC can be used for identifying the Caulis Spatholobi and its easily-confused species.

Object To study the protective effect of Rodobryum roseum (Hedw) Limpr. on acute myocardial ischemia. Methods Rat acute myocardial ischemia models were prepared by ligating their left coronary arteries. Changes of their S-T segment was observed on lead Ⅱ dynamic ECG. Degree of ischemia was assessed by the extent of S-T segment elevation. Lactic dehydrogenase (LDH), creative phosphokinase (CPK), superoxide dismutase (SOD) and malondialdehyde (MDA) were determined at the same time. Results R. roseum can significantly alleviate S-T segment elevation, being most evident at the dose of 2 g/kg (P
