Abstract

Leucaena leucocephala Leguminosea is a small leguminous plant native to tropical America now widely distributed in southern Asia and neighboring islands 1 Previous studies have show that gallocatechin epigallocatechin catechin and epicatechin extracted from the roots of L leucocephala exhibit nitrification inhibition against the bacterium Nitrosomonas europaea 2 L leucocephala was chosen for further phytochemical investigation The MeOH extract of its plants was subjected to solvent partitioning and chromatographic separation to afford 14 pure substances The chemical constituents in the plants of L leucocephala were separated by column chromatographyInvestigation on the MeOH extract of the plants has led to the isolation of 14 compounds These are four steroids 5α8αepidioxy24ξergosta622dien3βol 1 3 βsitosterol 2 4 βsitostenone 3 and stigmastenone 4 5 one triterpenoid lupeol 5 6 one glyceride 13dipalmitoyl2oleoylglycerol 6
