摘要：

A novel hydrolyzable tannin, chinquapinic acid [3], was isolated from the MeOH extract of the epidermal powder found on the leaf underside of Chrysolepis sempervirens in addition to two known tannins, vescalagin [1] and castalagin [2]. The structure of chinquapinic acid was established through spectroscopic data and auto-conversion to vescalagin. Scanning electron microscopy showed the yellowish powder to be crystal-like in appearance. These tannins are first examples for this class of compounds found as exudates on a plant surface.
