GC-MS Analysis on Volatile Oil from Branches of Picrasma quassioides

ObjectiveTo analyze the volatile oil from the branches of Picrasma quassioides.MethodsVolatile oil was extracted from the branches of P. quassioides by steam distillation. GC-MS method was used to analyze the components.ResultsA total of 49 compounds were isolated, and 46 compounds were successfully identified, which represented over 98% of the total oil composition. The major components of the volatile oil in the branches of P. quassioides included caryophyllene (12.83%), 12-oxabicyclo[9.1.0]dodeca-3,7-diene,1,5,5,8-tetramethyl-[1R-(1R*,3E,7E,11-R*)] (12.29%), 1-hexanol (9.96%), naphthalene, 1,2,3,5,6,7,8,8a-octahydro-1,8a-dimethyl-7-(1-methyletheyl)-[1S-(1a,7a,8aa)] (7.32%), aromadendrene oxide-(2) (6.69%), and α-caryophyllene (3.88%).ConclusionThe major components in volatile oil are terpenoids, hydroxy compounds, and other acyclic alkane compounds.
