Isolation of triterpenoids from the leaf of Avicennia marina

A simple and sensitive method for isolation of triterpenoids fromthe leaf of Avicennia marina. Soxhlet extraction method was used to get petroleum ether extract. The separations of triterpenoids were carried out by column chromatography and preparative thin layer chromatography. The structure of these compounds was determined by spectroscopic analysis such as FT-IR, UV,Mass spectra, 13CNMR.
