Catechin	21.0	12833	363.3	0.9419	10-170	2.30
Myricetin	27.2	12833	133.4	0.9792	4-125	1.60
Hyperoside	34.6	6333	153.3	0.989	6-165	0.85
Rutin	46.1	5250	110	0.9885	7-250	1.05

The relationship between peak area and analyte concentration is expressed as linear regression lines (y = ax + b), where y is the peak area measured by UV detector, x is the concentration (ppm) of the analytes, and a and b are the respective slope and intercept of the calibration curve. The correlation coefficient is r.
