Linear regression date, LOD, and LOQ of investigated compounds from Galla Rhois

Analytes	Linear regression data			LOD^b (μg/mL)	LOQ^c (μg/mL)
	Linear range (μg/mL)	r²	Regressive equation^a	LOD^b (μg/mL)	LOQ^c (μg/mL)
Gallic acid	0.5–1000	1.0000	y = 186,801x – 145,236	0.05	0.15
Methyl gallate	0.20–100	0.9999	y = 215,623x + 153,590	0.04	0.13
Digallic acid	0.5–100	0.9995	y = 107,350x – 133,444	0.09	0.26
Syringic acid	0.5–100	0.9994	y = 143,259x – 132,447	0.06	0.19
Ellagic acid	0.5–100	1.0000	y = 119,577x – 411,970	0.08	0.23
PGG	0.2–100	0.9997	y = 203,960x – 379,570	0.04	0.13

Here, y = peak area (mAU) and x = concentration (μg/mL) of the components.

LOD = 3 × signal-to-noise ratio.

LOQ = 10 × signal-to-noise ratio.

LOD, limit of detection; LOQ, limit of quantification.
