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

目的:研究注射用苦碟子(Ixeris sonchifolia extracts for injection,KDZ)对心肌缺血再灌注损伤大鼠心肌梗死面积、心肌酶和血黏度的影响。方法:大鼠以KDZ(2.5、5.0、10g生药/kg·d,ip),或0.9%NaCl治疗2天后,结扎大鼠冠状动脉左前降...目的:研究注射用苦碟子(Ixeris sonchifolia extracts for injection,KDZ)对心肌缺血再灌注损伤大鼠心肌梗死面积、心肌酶和血黏度的影响。方法:大鼠以KDZ(2.5、5.0、10g生药/kg·d,ip),或0.9%NaCl治疗2天后,结扎大鼠冠状动脉左前降支60min,再灌注120min造成心肌缺血再灌注模型,然后再立即给药一次。计算心肌梗死面积(MIS),测定血清肌酸磷酸激酶(CPK)、乳酸脱氢酶(LDH)、天门冬氨酸氨基转移酶(AST)活性及低、中、高切变率下全血黏度和血浆黏度。结果:与再灌注模型组比较,KDZ中、大剂量能明显缩小MIS,显著降低血清CPK、LDH及AST活性,小剂量也能降低血清LDH活性;KDZ大剂量使全血低、中、高切黏度及血浆黏度明显降低,中剂量也能降低全血低切黏度。结论:KDZ可缩小心肌缺血再灌注损伤大鼠的MIS,降低血清CPK、LDH、AST活性及血液黏度,发挥保护作用。展开更多
