Abstract: The chemical constituents of the fruits of cape jasmine (Gardenia jasminoides Ellis) were studied,seven compounds were isolated and their structures were elucidated by comparison of their physico-chemical properties and spectral data with those of reference data. The compounds were determined to be isoquercitrin(1), E-2'(4″-hydroxycinnamoyl) mussaenosidic acid(2), Z-2'(4″-hydroxycinnamoyl) mussaenosidic acid(3), geniposide(4), crocetin diethyl ester(5), crocetin(6), and crocin-1(7), respectively. Among them, compounds 1, 2, 3, 5 were obtained from genus Gardeniae for the first time.
