Antiinflammatory and Anticancer Properties of Grewia asiatica Crude Extracts and Fractions: A Bioassay-Guided Approach

Table 3

Quantification parameters of three phenolic acids, and four flavonoids from G. asiatica different fruit fractions.

Fractions	Compounds name	Wavelength	LOD	LOQ	Linear range (μg/mL)	r^2	Rt min	Concentration; (μg/g)
GAHAF5; (50% MeOH extract)	Catechin	300 nm	3.10	9.60	46.8-1500	0.9994	19.3	1230
	Chlorogenic acid		0.2	0.5	7.8-500	0.9995	20.7	491
	Caffeic acid		2.7	8.4	7.8-500	0.9991	21.8	957
	Morin		1.3	3.24	46.8-1500	0.9993	22.6	130
GAMF3; (100% MeOH extract)	Myricetin	330 nm	0.9	2.16	12.5-200	0.9985	24.1	217
	Quercetin	230 nm	1.1	2.75	1.6-25	0.9991	25.0	591
	Liquiritigenin		2	4.90	3.9-250	0.9987	23.2	24

LOD = limit of detection; LOQ = limit of quantification; ² = regression coefficient. Rt min = retention time in minutes; GAMF3 = Grewia asiatica methanolic fraction; GAHAF5 = Grewia asiatica hydroalcoholic fraction; 100% MeOH = 100% methanolic extract; 50% methanolic extract (50/50 H₂O: MeOH).
