A reversed-phase preparative HPLC method with UV spectrophotometric detection has been developed for the simultaneous isolation of eight hydrolysable tannins from dried fruits of Terminalia chebula, a traditional herbal medicine. Isolation of phytoconstituents was achieved by preparative HPLC using C18 column and acetonitrile-0.2% formic acid in water as mobile phase. The purities of the phytoconstituents were determined by HPLC and their structures were elucidated by spectroscopic (UV, 1
