[Analysis of liposoluble constituents in Holotrichia diomphalia by GC-MS and investigation their anti-inflammatory and analgesic activities]

To analysis liposoluble constituents of Holotrichia diomphalia by GC-MS and measure their anti-inflammatory and analgesic activities.The composition of liposoluble constituents were determined by GC-MS. The dimethylbenzene-induced mice inflammatory models were established. The pain models were obtained by hot plate and acetic acid in mice.Twenty-two components were identified from the petroleum ether extract of Holotrichia diomphalia. The major components were oleic acid, palmitic acid and palmitoleic acid. The petroleum ether extract was able to significantly inhibit the mice ear edema induced by dimethyl-benzene. The pain in mice caused by acetic acid and hot plate were evidently suppressed by the petroleum ether extract.The petroleum ether extract of Holotrichia diomphalia has obvious anti-inflammation and analgesic effects.
