Bis-iridoid glucosides from Abelia chinensis.
Seven bis-iridoid glucosides have been isolated from Abelia chinensis and were characterized by having a secoiridoid residue as unit A esterifying a C(10)-iridoid or a delta-lactone iridoid as unit B. Among these, compounds 1-3 are new and correspond to 7-O-acetyllaciniatoside IV, 7-O-acetyllaciniatoside V, and 7-O-acetylabelioside B, respectively. The structures of 1-3 were elucidated by spectral methods.
