Study on the Volatile Oils of Murraya microphylla

The essential oils from the leaves of Murraya microphylla (Merr. et Chun) Swing. growing in Sangya city, Hainan province have been studied by GC-MS and 22 compounds have been isolated and identified. Major compounds are identified as beta-terpinene (27.86%), decahdro-1, 1,7-trimethylene-1H-cyclopope] azulene (24.572%), 1,2,3,4,4 alpha, 5,6,8 alpha-octahydro-7-methyl-1-(1-methyl) naphthalene (11.426%), 3-carene (10.125%), 1, 1-dimethy1-2-(3-methyl-1, 3-butadienyl) cyclopropane (5.581%). According to Mr. Bipeixi's opinion, it exists two distinct sections within Murraya microphylla (Merr. et Chun) Swing. belongs to Murraya section Bergera. Monoterpene must be the dominated volatile fractions according Li Qian's opinion, but it is a exception. Maybe it has special taxonomic significance.
