RESUMO
Chinese Pharmacopoeia (2015 edition) recorded that Corydalis Rhizoma and Corydalis Decumbentis Rhizoma are derived from the genus Corydalis, sexual taste similar efficacy, but the actual clinical application of the focus is different. In this paper, the research progress of the two kinds of Chinese materia medica (CMM) is summarized from the three aspects of herbal research, chemical composition, and pharmacological action, which can provide reference for the identification and clinical application of the two drugs. Based on the core concepts of Q-marker, Q-marker components of Corydalis Decumbentis Rhizoma are forecasted and analyzed from original source, efficacy, pharmacokinetics, in vivo process, and the traditional drug property, which provides a theoretical basis for the establishment and improvement of the quality standard of medicinal materials.
RESUMO
Objective To observe compatibility rationality and comparative advantage of analgesic effect of Yuanhu Zhitong Dropping Pills (YZDP) compared with its ingredient and Yueyueshu through dysmenorrhea model induced by oxytocin.Methods Using dysmenorrhea model induced by ip injection of oxytocin to observe the effect of YZDP,Corydalis extract and Angelica dahurica extract on the latency and times of writhing response,and ELISA method was used to test the level of factors associated with pain in plasma,including 5-serotonin (5-HT),norepinephrine (NA),β-endorphin (β-EP),prostaglandin F2α (PGF2α） and prostaglandin E2 (PGE2),and level of dopamine (DA) in brain tissue.Q value was calculated by prime probability addition method,and according to whether the Q value was greater than one to determine whether the effects of YZDP was better than that of single component.Results Compared with model group,YZDP,Corydalis extract and Angelica dahurica extract could significantly prolong the latency of writhing response,decrease writhing times (P ＜ 0.05,0.01 and 0.001),and the Q values were greater than one.Compared with Yueyueshu,effect of Yuanhuzhitong dropping pills was significantly increased (P ＜ 0.05 and 0.01).YZDP and Corydalis extract could increase the level of β-EP as well as PGE2,and decrease the level of 5-HT,NA,DA,PGF2α and the ratio of PGF2α to PGE2 obviously in dysmenorrhea model rats (P ＜ 0.05,0.01 and 0.001).A.dahurica extract can significantly reduce 5-HT and DA level (P ＜ 0.05,0.01).Q values of β-EP,NA,DA and PGE2 were greater than one.Compared with Yueyueshu,YZDP increased the levels of β-EP and PGE2,and decreased the levels of 5-HT,PGF2α and PGF2α/PGE2 significantly (P ＜ 0.05 and 0.01).Conclusion YZDP has significant analgesic effect on dysmenorrhea model and has compatibility rationality because of better analgesic effect than ingredient use only.Compared with Yueyueshu,YZDP has the characteristic of working early and better analgesic effect.
