ABSTRACT
AIM To study the chemical constituents from Illicium brevistylum A.C.Smith and to evaluate their anti-inflammatory activities.METHODS The n-BuOH fraction of 80％ ethanol extract from I.brevistylum was isolated and purified by silica,ODS and Sephadex LH-20,the structures of obtained compounds were identified by spectral data.Then their anti-inflammatory activities were screened.RESULTS Nine compounds were isolated and identified as (7S,8R)-3,3',5-trimethoxy-4',7-epoxy-8,5'-neolignan-4,9,9'-triol (1),methylabieta-8,11,13,15-tetraen-18-oate (2),majusanin A (3),pubeside C (4),(+)-lyoniresinol-3a-O-α-L-rhamnopyranoside (5),junipercomnoside D (6),lyoniside (7),nudiposide (8),rhyncoside A (9).The inhibition rates of compounds 2,6,9 on NF-κB were 47.81％,37.33％,33.37％,respectively.CONCLUSION Compounds 1,5,7-9 are isolated from genus Illicium for the first time,and compounds 2,6,9 exhibit good anti-inflammatory activities.
