ABSTRACT

<p><b>OBJECTIVE</b>To investigate the chemical constituents of Securinega suffruticosa.</p><p><b>METHOD</b>It was isolated and purified by silica gel chromatography. Their structures were elucidated by means of spectral analysis.</p><p><b>RESULT</b>Four compounds were isolated and identified as ent-phyllanthidine (1), virosecurinine (2), 14,15-dihydrovirosecurinine (3) and viroallosecurinine (4).</p><p><b>CONCLUSION</b>All of four compounds were isolated from S. suffruticosa for the first time and were the enantiomers isolated from this plant before.</p>
