GC-MS analysis and antioxidant activity of volatile oil from leaves of Canarium pimela Leenh. in Rongxian county
摘要
Abstract
Objective]The chemical constituents and antioxidant activity of the volatile oil from leaves of Canarium pimela Leenh. in Rong County were studied to provide references for its medicinal development. [Method]The volatile oil was extracted by steam distillation, and then the composition of oil was analyzed by GC-MS. Chromatographic peak area normalization method was used to calculate the relative mass fraction of each ingredient . The DPPH· method was used to study its antioxidant activity . [Result]55 compounds were isolated and 53 compounds were identified in the leaves that composed about 98.130% of the total volatile oils, in which the ratio of monoterpenoids and sesquiterpenes was relatively higher, 20 and 18 types, respectively. The principal chemical constituents of the volatile oil were ere-mophila-1 (10), 11-diene (11.652%),α-selinene (10.291%), γ-muurolene (9.719%), α-pinene (9.208%) and 1,2,3,4,4a,7-hexahydro-1,6-dimethyl-4-(1-methylethyl)-Naphthalene (7.523%). The scavenging ratio for the DPPH· radicals reached 63% at the concentration of 1 . 2 g/L . [Conclusion]There are many chemical constituents in the volatile oil and the main compounds are monoterpenoids. The volatile oil shows certain antioxidant activity and can be further studied as a natural spice and antioxidant.关键词
