Results of the regression analysis on the calibration curves and the detection limits.

Compound	Regression equation^1	Correlation coefficient ()	Linear range (×10^−4 g mL^−1)	Detection^2 limits (10^−7 g mL^−1)
Glucose		0.997	0.02–2.0	3.5
Fructose		0.998	0.02–2.0	1.8
Chlorogenic acid		0.995	0.02–2.0	6.2
Luteolin		0.998	0.02–2.0	5.1

y is the peak area; x is the concentration of the analytes (g mL⁻¹).
²The detection limits correspond to the concentrations of the signal-to-noise ratio of 3.
