Objective: To study anti-
inflammation, expectorant and an tibacterial
activities of T. chinensis in Hubei. Method: Phenosulfon
phthalein e xcretion (PSP) test to observe the
expectorant effect; the ear
inflammation indu ced by dimethylbenzene in mice and DTH induced by DNCB in mice to evaluate the a nti-inflammation activity; MIC was determined by 2-fold broth dilution method; t heKarber measure to determine the acute toxicity of T. chinensis. Result: 14.9, 7.5 and 3.8 g/Kg of T. chinensis showed significant expectorant action, signifi cant inhibitory action towards acute inflammation induced by dimethylbenzene epi dermidis, weak antianaphylaxis action in the DTH induced by DNCB in mice; The an tibacterial result test in vitro showed that T. chinensis can significantly inhi bit Staphylococcus aureus?Staphulococcus epidermidis and Pseudomonas aeruginosa (MIC:31.3 g·1-1,),and also inhibit beta streptococcus(MIC:125 g·1-1);The ac ute toxicity experiment showed that the LD50 is 148.7 g/Kg crude drugs. Conclusi on: T. chinensis showed significant activities of expectoration, anti-inflammati on, and definite Antibacterial action. Furthermore, its toxicity is low.
