Abstract:

This paper reports the analysis of chemical composition of volatile oil from daylily, in which steam distillation was used for the extraction of volatile oil from daylily, followed by GC-MS separation and identification and quantification of relative content of each identified compound by peak area normalization. Totally 100 compounds were separated, of which, 36 were identified and altogether accounted for 95.68% of the total volatile oil and 3-furanmethanol was the most predominant compound, with a relative content of up to 76.17%.

Key words: daylily, steam distillation, volatile oil, GC-MS
