Abstract:
Objective To investigate the low polarity compounds from Polygonum paleaceum Wall .Methods The ethyl alcohol extracts of Polygonum paleaceum Wall were extracted with petroleum ether .The components were separated and iden-tified by GC-MS and elucidated by the comparison with the standard mass spectral data .The relative contents in percentage were calculated using the area normalization method .Results 40 compounds were identified .Naphthalene and (E)-9-octadece-noic acid ethyl ester were the main components .Conclusion The low polarity components of Polygonum paleaceum Wall were mainly consisted of naphthalene and (E)-9-octadecenoic acid ethyl ester (27 .02% ) ,along with hexadecanoic acid (4 .18% ) , 13 ,27-cycloursan-3-one (2 .55% ) and cis-11-eicosenoic acid (1 .31% ) .
