Iridoid Glucosides From Eremostachys Moluccelloides Bunge

Abstract

From the aerial parts of Eremostachys moluccelloides BUNGE, a new iridoid glucoside, lamalbidic acid (7). was isolated as its choline salt 7a together with six known iridoid glucosides, 5-deoxysesamoside (1). 6 ss-hydroxy-7-epiloganin (2), lamalbide (3), shanzhiside methyl ester (4), sesamoside (5), and 5-deoxypulchelloside 1 (6). The structures of 7a and 7 (obtained from 7a) were elucidated by spectroscopic (UV. IR, 1D- and 2D-NMR, and ESI-MS) methods.
