Abstract

This study was performed to examine the effect of ${\gamma}$-irradiation on the volatile organic compounds of Cuscutae Semen (Cuscuta chinensis L.). The volatile organic compounds of non-irradiated and 10 kGy ${\gamma}$-irradiated Cuscutae Semen were isolated using SDE apparatus and analyzed by GC/MS. Limonene, ethanol, (E)-2-decenal, hexadecanol, nonanoic acid and nonanal were detected as dominant compounds. Before irradiation, the total concentration of volatile organic compounds of Cuscutae Semen was approximately 189.90 mg/kg. After irradiation at 10 kGy, total concentrations increased to 299.46 mg/kg, but, the profile of volatile compounds including the essential oils of Cuscutae Semen was not differ from non- and irradiated sample. Therefore it was improved the extraction yield of useful compounds such as limonene, menthol, piperitone and isomenthone by irradiation.
