Twenty compounds have been isolated from the leaves of Chinese holly (Ilex cornuta Lindl. ex Paxt.), Among them, 16 compounds have been identified i. e. Gouguside 1 (pomolic acid 3-β-O-a-L-arabinopyranoside V); Gouguside 2 [3-β-0-D-glucopyranoside-pomolic acid (28→ 1 )- β-D-glucopyranosyl ester VI] ...
