[Method] Broth microdilution method and checkerboard dilution method were used and the reference strain E. coli ATCC25922 and clinical sample separation strains of E. coli and Salmonella were selected to determine the minimum inhibitory concentration（ MIC） and fractional inhibitory concentration（ FIC）. [Result] The MICs of Berberis julianae Schneid and Cinnamomum camphora（ L.） Presl. for E. coli and Salmonella were both 1 mg /mL,and that of other antibiotics for the two strains were in the quality control range provided by NCCLS. [Conclusion] The synergistic effect or additive effect were observed when they were applied with the commonly used antibiotics.展开更多
Through investigating the population change of Cinnamomum camphora(L.) Presl. in Wuxi City, the research found that C. camphora(L.)

Presl. in Wuxi City, the research found that C. camphora(L.) Presl. in the past century had already become common species from rare species, then explored the causes, advantages and disadvantages of the change. In view of sustainable development of urban greening, zonal vegetation and fl ora, this paper explored the scientifi c and reasonable application of tree species and also protection of urban plant diversity.展开更多

Presl leaf from Fujian Province(mean content 1.084%).58 compounds were identified and their relative contents were determined by normalization method of areas.58 compounds represented 96.909% of total peak areas.Its main compounds included linalool(43.732%),camphora(14.431%),1,8-cineole(10.457%),safrole(7.079%),α-terpineol(2.570%),and β-phellandrene(2.231%),etc.These constituents represented 80.5% of total peak areas.展开更多
