In this work, an evaluation of the biological activities of Globularia alypum L. extracts and their global chemical composition was realized. Extracts from G. alypum were obtained by two extraction methods. The composition of
polyphenols (8.5-139.95 g
gallic acid equivalent/Kg of dry mass),
tannins (1.39-18.65 g
catechin equivalent/Kg of dry mass),
anthocyanins (8.17-70.69 mg
cyanidin equivalent/Kg of dry mass) and
flavonoids (0.31-19.28 g
quercetin equivalent/Kg of dry mass) was evaluated. The samples were subjected to a screening for their
antioxidant activities using the DPPH* and
ABTS*+ assays. For the first time, the anti-
tuberculosis activity (H(37)Rv) for G. alypum was tested against Mycobacterium tuberculosis. The strongest
antioxidant activity was obtained for the
methanol extract (IC(50 ) = 15.58 ± 0.168 mg/L) and the best anti-
tuberculosis activity was obtained for the
petroleum ether extract (IC(50 )= 77 mg/L). We have found a positive correlation between the total phenolics content and the
antioxidant activity R2 = 0.88 (DPPH*) and R2 = 0.97 (
ABTS*+). We have found also a positive correlation between the
flavonoid content and the
antioxidant activity R2 = 0.91 (DPPH*) and R2 = 0.91 (
ABTS*+).
