摘要

Phytochemical investigation on the whole plants of Iris japonica led to the isolation of four new aromatic glycosides. Their structures including the absolute configurations were determined by spectroscopic and chemical methods as (-)-4-hydroxy-3-methoxy acetophenone 4-O--d-{6-O-4-O-(7R,8S)-(4-hydroxy-3-methoxyphenylglycerol-8-yl)-3-methoxybenzoyl}-glucopyranoside (1), (-)-4-hydroxy-3-methoxy acetophenone 4-O--d-{6-O-4-O-(7S,8R)-(4-hydroxy-3-methoxyphenylglycerol-8-yl)-3-methoxybenzoyl}-glucopyranoside (2), (-)-4-hydroxy-3-methoxy acetophenone 4-O--d-{6-O-4-O-(7R,8R)-(4-hydroxy-3-methoxyphenylglycerol-8-yl)-3-methoxybenzoyl}-glucopyranoside (3), (-)-4-hydroxy-3-methoxy acetophenone 4-O--d-{6-O-4-O-(7S,8S)-(4-hydroxy-3-methoxyphenylglycerol-8-yl)-3-methoxybenzoyl}-glucopyranoside (4), respectively.
