Abstract

The volatile organic components obtained from fruit peel of Citrus medica L. using Headspace Trap (HS-Trap)sampling techniquewere characterized by gas chromatography-mass spectrometry (GC-MS).The results shows that peak responses of44 components were obtained by using HS-Trap sampling technique coupled with GC-MS, predominantly containsmonoterpene group accounting for 98.46%,of which, d-limonene was the most abundant (85.93%), followed by sabinene (6.85%), myrcene (3.46%) while out of them 24 possesses specific aroma. The Headspace Trap (HS-Trap) sampling technique used in present study is advantageous over the conventional extraction technique. Technique is useful to avoid analyte losses, contamination. The other advantage of this technique is minimum sample requirement, capable to detect trace level component and minimum time require for extraction/sampling. The HS-Trap technique can be used as quick screening tool for authenticity determination and routine quality check of various citrus essential oil. The present study may found helpful for further work and may add as a valuable source of essential oil in flavor and fragrance industry.
