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-α -Larabinopyranoside Ⅴ);Gouguside 2 〔3-β-O-D-glucopyranoside-pomolic acid ( 28 →1) -β-D-glucopyranosyl ester Ⅵ〕; Gouguside 3〔like 3-β-O-( β-D-glucopyranosyl-α -L-arabinopyranosyl) -pomolic acid( 28→1) -β-Dglucopyranosyl ester Ⅶ 〕;Gouguside 4 〔3-β-O-( β-D- glucopyranosyl-α -L-arabinopyranosyl) -pomolic acid( 28 →1) -β-D-glucopyranosyl ester ⅩⅦ 〕;Gouguside 5 (pomolic acid 3-β-O-α -L-2′ -acetoxyl- arabinopyranosyl28-O-β-D-glucopyranosyl ester, namely Cornutaside A, ⅩⅧ); Gouguside 6 〔3-β-O-( β-D-glucopyranosyl-( 1 →2) -4′ -acetoxyl-α -L-arabinopyranosyl pomolic acid ( 28→1)-β-D-glucopyranosyl ester ⅩⅨ〕; Gouguside 7 ( 3-β-O-α -L-arabinopyranosyl-pomolic acid -28-O-β-D-glucopyranosyl erter ⅩⅩ);Daucostorol (Ⅷ);2, 4dihydroxybenzoicacid (Ⅰ); 3, 4- dihyroxycinnamunic acid (Ⅱ、Ⅳ)and 5 Longchain fatty acids (Ⅲ、Ⅵ 、 Ⅶ 、Ⅷ 、ⅩⅣ)。Of which, Gouguside 1 , Gouguside 2, Gouguside 6 andGouguside 7were first isolated in I. cornuta , Gouguside 3 and Gouguside 4 are new compounds.
