摘要
应用GC和GC/MS/DS分析了羯布罗香(Dipterocarpus tubinatus Gaertn.f.)和云南龙脑香(D.retusus Bl.)两种龙脑香科植物树脂精油的倍半萜类成分。羯布罗树脂精油的主要成分为δ-榄香烯、α-古芸烯、γ-木罗烯和α-杜松烯,其中α-古芸烯的相对含量最高。云南龙脑香树脂精油中则以别芳萜烯和α-蛇麻烯为主要成分,别芳萜烯相对含量最高。羯布罗香树脂精油中δ-榄香烯、α-古芸烯、γ-木罗烯、α-杜松烯、β-澄淑烯和γ-榄香烯的相对含量有明显季节变化,但是精油的倍半萜类成分的组成没有季节差异。这两种植物的树脂精油均有明显抗菌活性。
The sesquiterpenes of the oleoresin essential oils of Dipterocarpus tubinatus Gaertn. f. and D. retusus Bl. were analyzed by GC and GC / MS / DS for relative contents and seasonal variations. The main compounds in the oleoresin essential oil of D. tubinatus are δ-elemene, α-gurjunene, γ-murolene,α-cadinene, and the α-gurjunen relative content is highest. Then, the main compounds in oleoresin essential oil of D. retutsus are allo-aromadendrene and α-humulene, and the allo-aromadendrene relative content is highest. Seasonal variations were different at highly levels for δ-elemene.α-gurjunene, γ-muurolene, α-cadinene, β-cubebene, γ-elemene between the oleoresin essential oil collected in dry season and the oleoresin essential oil collected in rain season of D. tubinatus. But the composition of the oleoresin essential oil of D. tubinatus was not affected by season. The oleoresin essential oil both D. tubinatus and D.retusus had obvious activated in antibacterial test.
