| Abstract: | Objective]To analyze the aroma components and the relative contents in the flowers of two Dendrobium species,D.hancockii and D.trigonopus.Method]The volatile constituents and their contents were analyzed by solid-phase microextraction(SPME)and gas chromatography-mass spectrometry(GC-MS).Result]For the first time,the volatile constituents were analyzed in fresh flowers of D.trigonopus and thirty-five compounds were characterized.Fifty-two compounds were characterized in D.hancockii.The main volatile constituent in both the two species was olefin.Conclusion]The characteristic aroma components are(Z)-β-Ocimene,β-Caryophyllene and Linalool in D.hancockii flower.The characteristic aroma components are(Z)-β-Ocimene,β-Caryophyllene and d-(+)-Limonene in D.trigonopus flower. |
