ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect of Taohong Siwu Tang and its fractions on hotplate-induced pain in mice, acetic acid-induced writhing response, dysmenorrheal model and isolated uterine contraction in vitro in mice, and discuss material basis of effect sites.</p><p><b>METHOD</b>The samples of fractions were prepared by macroporous adsorptive resins (TH-1-TH-15). In the whole animal experiment, the hotplate-induced pain mice model was established to observe the effect of the samples on pain threshold in mice; the acetic acid-induced writhing response mice model was built to observe the effect of the samples on the writhing response in mice; the mice dysmenorrheal model was established to observe the effect of the samples on the writhing response, and calcium ion (Ca2+) and nitric oxide (NO) levels in uterine tissue of mice. In the isolated uterus contraction experiment, the oxytocin-induced isolated uterus contraction mice model was established to observe the effect of the samples on the isolated uterus contraction index. HPLC-DAD method was adopted for the content determination of effect sites.</p><p><b>RESULT</b>According to the evaluation of the integration geological effect, beside TH-2 and TH-4, other three active fractions (TH-9, TH-10 and TH-11) extracted from Taohong Siwu Tang are the main effect sites. Their chemical components were analyzed and identified as monoterpene glycosides, phthalides, organic acids, etc.</p><p><b>CONCLUSION</b>The effect sites of Taohong Siwu Tang on dysmenorrhea are TH-9, TH-10 and TH-11, which are 30% - 50% active fractions obtained from water-soluble small-molecular fractions by gradient elution using ethanol through macroporous absorption resin. Compared with TH-10 and TH-11, TH-9 shows stronger effect, which may be related to the type and content of chemical components it contains.</p>
