Abstract: Twelve compounds were isolated from the 80% ethanol extract of the ripe fruits of Chaenomeles cathayensis (cf.White Flower) by column chromatographies on silica gel,Diaion HP20 and Sephadex LH20.On the basis of spectral analyses,their chemical structures were elucidated as ()epicatechin (1),(+)catechin (2),hydroquinone (3),3.4dihydroxybenzoic acid (4),gallic acid (5),methyl 3hydroxybutanedioic acid (6),quercetin (7),oleanolic acid (8),betulinic acid (9),pomolic acid (10),procyanidin B2 (11),and procyanidin C1 (12),respectively.These compounds were isolated from the ripe fruits of title plant for the first time.

Key words: Chaenomeles cathayensis (cf.White Flower), ripe fruits, chemical constituents, isolation and identification
