【Abstract】 The qualitation and quantitative analysis of verticine in fritillary by TLC-densitometry was reported. The experimental conditions was explored. A linear relation is obtained in the range of 0.25～2.02μg; Recovery was 97.62% (n = 3. RSD = 2.0%).The results indication that the method was simplicity.rapid and accurate.更多还原
