Chemical Constituents from the Hulls of Oryza sativa with Cytotoxic Activity

  • Published:
Chemistry of Natural Compounds Aims and scope

Abstract

Five new compounds, orizaterpenol (1), orizaterpenoid (2), orizaterpenyl benzoate (3), orizanor-diterpenyl benzoate (4), and orizaditerpenyl benzoate (5), along with nine known compounds, were isolated and identified from the rice hulls of Oryza sativa. Their structures were elucidated with the help of different spectroscopic techniques. Orizaterpenol (1) and the known momilactone A (6) and B (7) were found to have cytotoxic effects against P388 murine leukaemia cells, while the other new and known compounds exhibited weak cytotoxicity.
