Abstract

Bioactivity-guided fractionations for ACAT inhibitor led to the isolation of guineensine from the CHCl3 extract of Piper longum. Its structure was identified by spectroscopic means (IR, UV, MS and NMR). Guineensine inhibited ACAT activity in a dose-dependent manner with an IC50 value of 3.12 µM.
