Methods the optimal proportion of levant storax oil and dalbergiae odoriferae oil , which were active ingredients of the traditional chinese medicine styrax and dalbergiae odoriferae , was bolted by using uniform - design method ; the myocardial ischemia model of rats was set up through the induction of isoprel and the above rats were divided into 5 groups , which were model control group , high dose group of shuangxiangyou , middle dose group of shuangxiangyou , low dose group of shuangxiangyou , and positive control group of muskone 方法传统中药苏合香和降香的有效成分苏合香油和降香油最佳配比采用均匀设计方法筛选；建立由异丙肾上腺素造成的心肌缺血大鼠模型，将实验分为模型对照组、双香油高、中、低3个剂量组及冠心苏合丸阳性药物对照组后进行药效学实验。

Results among the selected dosages , the theoritical optimal proportion of levant storax oil and dalbergiae odoriferae oil , which were both in the shuangxiangyou soft capsules , was 1 : 5 : 1 . 0 ; the pharmacodynamics experiment indicated that the shuangxiangyou had the significant anti - myocardial ischemia effect compared with model control group 结果双香油软胶囊中苏合香油、降香油两者在所选择剂量范围内的理论最佳配比为1 . 5 : 1 . 0 ；抗心肌缺血药效学试验表明，双香油有显著的抗心肌缺血的作用，与模型对照组比较具有显著的差异。
