The Refractive Index, Relative Density, and total phenolic in the CS essential oil samples.

Sample	Refractive index	Relative density (g/mL)	Polyphenol content (mg/100 mL)
Conventional CCH Isolated EO	1.4720 ± 0.02	0.852 ± 0.01	0.362 ± 0.01
DF-GC/MS-HUS Prototype** Isolated EO	1.4725 ± 0.01	0.849 ± 0.01	0.789 ± 0.01*

*Indicates a significant difference between Conventional CCH and prototype methods (p < 0.05).
