Studies on the constituents of Gardenia species. III. New iridoid glycosides from the leaves of Gardenia jasminoides cv. fortuneana Hara.

Two new iridoid glycosides, 7 beta,8 beta-epoxy-8 alpha-dihydrogeniposide (1) and 8-epiapodantheroside (2), were isolated, together with six known (3-8) and three artifact (9-11) iridoids, from the leaves of Gardenia jasminoides cv. fortuneana Hara. Their structures were established based on chemical and spectral data.
