Table 1 Comparison of extraction yield and α-glucosidase inhibition of BME using different solvents

From: Anti-hyperglycemic activity of polyphenols isolated from barnyard millet (Echinochloa utilis L.) and their role inhibiting α-glucosidase

Extraction solvent	Extraction yield^a (%)	α-glucosidase
Extraction solvent	Extraction yield^a (%)	IC₅₀ (μg/mL)	Inhibition^b (%)
Ethyl acetate	2.0 ± 0.2	70.2 ± 0.3	94.8 ± 4.2
Ethanol	4.1 ± 0.5	168.4 ± 3.5	88.7 ± 3.5
50 % ethanol	5.3 ± 0.2	199.6 ± 4.3	50.4 ± 4.5
Methanol	4.5 ± 0.7	182.5 ± 2.8	56.4 ± 2.2
Water	10.4 ± 1.1	NT	NT

All extracts were examined in a set of experiments repeated three times
NT not tested
^aExtraction yields are given as g/2 g dry weight
^bSample concentration was 0.2 mg/mL
