abjective:For the study of demonstration objects: representative geoherbs aconite, Evodia Evodia, the aconite traditional efficacy (potency, functions, attending) and pre-experimental results on the basis of pre-Evodia, aconite poisoning effects of the law and the material basis of the study, according to electionfixed representative efficacy/toxicity evaluation, the biological potency assay (quantitative) and biological activity limit assay (semi-quantitative) biological quality control methods. Methods:Mainly USES the method in vitro, in vivo method to select strong heart shock, resistance to lateral root of aconite main functions; Evodia rutaecarpa analgesia spasmolysis, as biological titer evaluation on the exploratory experiment index. Cardiac function using lateral root of aconite on normal SD rats of Langendorff heart perfusion in vitro and to observe changes of heart rate after into the reagent; Shock resistant lateral root was studied by tail intravenous injection of endotoxin on endotoxin shock caused by the animal’s protection against the death. Evodia rutaecarpa analgesia, spasmolysis effects of rabbit in vitro were used respectively to muscle tension test and acetic acid in mice body torsion reaction. Results:Qualitative experiment can verify aconite Qiangxin, anti-shock effect and Evodia has analgesic, inhibition of smooth muscle contraction; the aconite decoction of endotoxin-induced shock prolong their survival time and survival percentage, indicating that aconite water-solublepart of the endotoxin-induced shock treatment. Muscle tension in vitro experiments, the ethanol extract of Evodia or water extract with increasing concentration, the inhibition of smooth muscle also increased; analgesia in vivo experiments can be drawn, the Evodia water extraction, alcohol extraction for the intraperitoneal injection of acetic acid caused small mouse acute peritonitis lasting pain stimuli are inhibited, and there is a significant difference.Using a semi-quantitative method to establish the biological quality control method, derived aconite alkaloids extract (concentration equivalent to the aconite raw herbs55.6g of x10-3)3ml starting to enhance the role of the heart rate,6ml of heart rate began to reach toxic dose;5mlis a critical point of the maximum tolerated dose and minimum toxic dose. Conclusion:Optimize the establishment of experimental system complies with the requirements of aconite bioassay. Law may become a complement of the the existing the aconite quality control methods. Through this experiment, the initial indicators of pharmacology to test the reaction of the efficacy of different samples.
