[Abstract]
10 crystalline compounds have been isolated from Phyllonthus urinaria Linn,Collected from Guangzhou. They were identified as triacontanol(Ⅱ),stigmastetol(III),lupo-20(29)-ene-3β-01(IV),dotriacontanoic acid(V),succinic acid(VI) and β-stigmasterol-3-O-β-D-glucoside(VII).Their structures were elucidated on the basis of spectral data of IR MS, 1H and 13CNMR and other chemical methods.The other four are pending further identification.
