Methods The chemical constituents were isolated by various column chromatographic methods and the structures were elucidated and characterized by spectral evidences. Result Thirteen compounds were obtained and identified as 3β-acetoxy-20-taraxasten-22-one （1）, bauerenyl acetate （2）, 3β-acetoxy- 11-oxours-12-ene （3）, oleanic acid （4）, oleanane （5）, 8-desoxyartelin （6）, aesculetin （7）, ferulic acid （8）, vanillic acid （9）, sonchifolinin （10）, hexacosanol （11）, β-sitosterol （12）, and daucosterol （13）. Conclusion Compounds 1, 5, and 8 were isolated from this genus for the first time; compound 7 was obtained firstly from this plant.展开更多

Methods: Thirty-three type 2 DM patients were treated with 20 ml ISH per day, intravenously dripping for 15 days; 31 patients in the red sage treated group were treated with composite red sage injection intravenous dripping for 15 days, and their changes of platelet membrane glycoprotein Ⅱb/Ⅲa compound (GPⅡb/Ⅲa), granular membrane protein-140 (GMP-140), platelet aggregation rate (PAgR) and hemorrheology were observed. Results: After treatment with ISH, the GPⅡb/Ⅲa compound positive rate of 33 type 2 DM patients were lowered (P<0.05), GMP-140 showed lowering trend, PAgR obviously reduced, and compared with before treatment it showed significant difference; comparison between the two groups after treatment,it showed significant difference (P<0.05, P<0.01). At the same time, the various parameters of hemorrheology displayed significant improvement. There was no adverse effect during the course of treatment. Conclusion: ISH could improve platelet function and abnormal hemorrheology of type 2 DM patients, which is vital for the treatment of DM and their vascular lesion.展开更多
