Parameters of the calibration curves for different phenolic standards

Phenolics	Linearity^a	Detection limit (μg/ml)^b	Quantification limit (μg/ml)^b	Recovery (%)^c
Sinapic acid	1.00	0.20	0.50	98.98 ± 0.21
Sinapine	0.99	0.20	0.50	98.80 ± 0.22
Sinapoyl glucose	0.99	0.40	0.80	99.60 ± 0.16

^aLinearity was expressed as the correlation coefficients of each calibration curve which was determined by five calibration points

^bMeans of triplicate measurements ± standard deviation; quantification limit is the concentration at which the determination was most accurate with recovery over 98.00%

^cRecovery values are expressed as mean ± standard deviation conducted in canola extracts through spiking
