Quantitative difference of consituents in Angelica acutiloba between feeding damage and control

Abstract

Root of Angelica acutiloba is assigned as an important Kampo medicine. We compared the constituent difference of leaves between feeding damage by insects and control. In the present study, we clarifies significant differences in quantities of metabolites such as gamma-Terpinene, Falcarindiol, Vitamin E 1-tetradecanol, Ligustilide, L-Tetradecyl acetate based on principal component analysis. Based on the results, we also propose differences in metabolic pathways of secondary metabolites between the feeding damage and control.
