OBJECTIVETo investigate the chemical characteristics of pericarps from Illicium species for developing a taxonomic and identification method for Illicium species.

METHODTwenty two samples from 17 Illicium species were detected with HPLC-MS. The chromatographic data were analyzed by cluster analysis using SAS software.
