Study on the Structure of Monoterpenic Isomers in Plant Oil

Many species of terpenic compounds were isolated by using GC/MS technique from the volatile oil of zathaxylum bungeanum with insecticidal activity, 12 monoterpenic isomers were studied and identifled by means of the library search and interpretation of mass spectra, in the volatile oil. 5 monoterpenic compounds were first detected in the same plant oil.
