Abstract:

Abstract：Objective: Study on the effects of plant hormones on the content of total alkaloids, mesaconitine, aconitine and hypaconitine in Aconitum carmichaeli. Method: The hormones were sprayed on the Aconitum carmichaili at the seedling growing period and tubers expanding period. Acid dye colorimetry and RP-HPLC was used to the detection of the total alkaloids and mesaconitine, aconitine and hypaconitine. Results: The treatment of 6-BA and IAA had inhibitory effects on the content of total alkaloids，while GA、KT、NAA were not influence the result. NAA increased the content of mesaconitine、aconitine, but inhibited the hypaconitine. The other hormones inhibited the contents of the three alkaloids. Conclusion：The hormones had the effects on the content of alkaloids in Aconitum carmichaeli. The results can provide scientific basis for the application of plant hormones on Aconitum carmichaili during cultivation.
