OBJECTIVE
To search the anti-inflammatory fraction of Albizia julibrissin.
METHODS
Inflammatory model of Kunming mice ear edema induced by croton oil and determination combined with the LC-MS-MS-guided fractionation and isolation were used.
RESULTS
The n-butanol fraction (AJ-B) obtained from the ethanolic extract of the Cortex albiziae was the major active fraction. The lignan glycosides fraction (AJ-B-1), which was further isolated from AJ-B, showed significant anti-inflammatory activity and exhibited dose-dependent relationship in the dose of 5 to 20 mg x kg(-1).
CONCLUSIONS
The method of bioassay-guided fractionation and isolation combined with the LC-MS-MS determination may be of benefit to the logical studies on the bioactive fractions or constituents of traditional Chinese materia medica.
