Structural Identification of Two Antioxidant Quinic Acid Derivatives from Garland (<i>Chrysanthemum coronarium</i> L.)

Abstract

The structures of a novel compound, 3,5-dicaffeoyl-4-succinylquinic acid, and the related compound 3,5-dicaffeoylquinic acid were determined by analysis of spectral data. These caffeoylquinic acid derivatives, with antioxidative activity, were isolated from the leaves of garland (Chrysanthemum coronarium L.). Keywords: Antioxidants, dicaffeoylquinic acids, Chrysanthemum coronarium
