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

Abstract

Two new iridoid glycosides, 7β,8β-epoxy-8α- 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. © 2003 Pharmaceutical Society of Japan.
