Fig. 3. Percentage of relaxation induced by the fractions partitioned with n-hexane, ethyl acetate, and n-butanol (n=4). The penile corpus cavernosum smooth muscle that had been precontracted with 10−5 M of phenylephrine (Phe) was treated with 4 concentrations of each fraction. The submaximal penile contractile responses induced by Phe were taken as 100%, and all subsequent responses to Artemisia capillaris fractions were expressed as a percentage of this value. Each point represents the mean±standard deviation of the percentages (**p<0.01 vs. 0.1 mg/mL).
