Essential oil extracted from Senecio cannabifolius Less.of senecioneae of compositae is found to have significant antivirus effect against Respiratory Syncytial Virus and HerpesSimplex Virus 1 and delay pathogenic action of Parainfluenza Virus,Coxsackie Virus B3,Adeno virus-3 and Influenza Virus of Mouse by using cytopathic effect method.In order to find antivirus components,the constituents of essential oil from Senecio cannabifolius Less.were analysed by techniques of GC-MS.The yield of essential oil is 0.22%(mL/100 g) and the identified relative contents of it is 88.47%.26 compounds have been tentatively identified,including n-Hexadecanoic acid(27.01%),carotol(13.73%),9,12-linoleic acid(9.99%),α-pinene(9.28%),β-pinene(5.58%),in which the terpene compounds account for 47.42%,fatty acid account for 37.61% and else compounds only a 3.44%.The results imply terpene and fatty acid with high content may relate to anti-virus activity of essential oil from Senecio cannabifolius Less.
