Seven new monoterpenoid indole alkaloids, kopsiofficines A~G, together with twenty known alkaloids, were isolated from the stems of Kopsia officinalis. Their structures were elucidated on the basis of extensive spectroscopic methods. The anti-inflammatory activities of all alkaloids were evaluated on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells by the inhibiting the production of IL-1β, PGE2 and TNF-α. Among them, kopsiofficines A (1), kopsiofficines B (2), kopsiofficines D (4), kopsiofficines F (6), kopsiofficines G (7), 12-methoxykopsine (11), kopsinoline (15), (-)-N-methoxycarbonyl-11,12-methylenedioxykopsinaline (16), kopsinine (18) and kopsinic acid (20) exhibited significant anti-inflammatory activity, which were comparable to that of dexamethasone. The results supposed that the acetonyl group at C-5 of monoterpenoid indole alkaloids play an important role in their anti-inflammatory activity.

Key words: Kopsia officinalis, kopsiofficines A~G, anti-inflammatory, monoterpenoid indole alkaloids
