Study on accumulation law of peimine in different Fritillaria thunbergii cultivar

: In order to study the accumulation of Fritillaria thunbergii cultivar, peimine content in Xiaye, Kuanye, Duozi and Xiaosanzi bulbs of different sizes and parts was determined by HPLC-ELSE. The results indicated that the peimine content varied significantly with the cultivar type, the size and part of bulb. The distribution laws of peimine were as follow: Xiaosanzi > Duozi > Xiaye > Kuanye, small-size bulb > big-size bulb, core bud > scale. The peimine yield per plant in Duozi was the highest.
