245. Studies on Monoterpene Glucosides and Related Natural Products. Part 51. Absolute Structures of Hydrangenosides A, B, C, D, E, F, and G. Novel Type Secoiridoid Glucosides from Two Hydrangea Plants

From Hydrangea macrophylla var. macrophylla, four new secoiridoid glucosides, hydrangenosides A, B, C and D, were isolated, along with the known iridoid glucosides loganin, secologanin, secologanic acid and sweroside.Moreover, hydrangenosides E, F, and G,

A NOVEL TYPE SECOIRIDOID GLUCOSIDE, HYDRANGENOSIDE A FROM HYDRANGEA MACROPHYLLA

Hydrangenoside A, isolated along with its three congeners from Hydrangea macrophylla, was proved to have a novel type of structure which is thought to be biosynthesized through an aldol-type condensation of secologanin with a unit formed by the shikimate-
