Effects of three treatments of 50 mg l −1 fungal elicitors (F 5), 50 mg l −1 salicylic acid (SA) and 50 mg l −1 F 5+50 mg l −1 SA were studied on membrane-lipid peroxidation. Peroxidase (POD), glucose-6-phosphate dehydrogenase (G6PDH) and taxol production in cell suspension cultures of Taxus chinensis were investigated. The results showed membrane-lipid peroxidation caused by fungal elicitor F 5, prepared from fungus isolated the inner bark of T. chinensis, was decreased by the addition of salicylic acid, even if the latter also induced cell membrane-lipid peroxidation. F 5+SA resulted in improving the activity of POD and G6PDH compared to single F 5 treatment, and achieved the greatest taxol production of 11.5 mg l −1, being 1.5, 2.3 and 7.5 times higher than that of F 5, SA and the control. By analysis of membrane-lipid peroxidation, POD and G6PDH activity, the reason combined treatment F 5 and SA improved taxol production was reduction of membrane-lipid peroxidation induced by F 5. The studies showed that treatment of F 5+SA on T. chinensis cultures not only gained more biomass than single F 5 treatment, but also achieved the highest taxol production.
