Study on phytochemical, antibacterial and antioxidant properties of Genitiana kurroo Royle

Abstract

Gentiana kurroo Royle is an endangered bitter medicinal plant of the Indian subcontinent region. This medicinal plant mainly grows in Kashmir, Himachal Pradesh, and North-west Himalayas. Native people frequently use the medicinal plant’s root and rhizome for various local remedies. The leaf and root samples of the plant were studied for their phytochemicals screening and antibacterial and antioxidant properties. The methanolic root extract as a comparison to methanolic leaf extract was detected with high concentration of phytochemicals like alkaloids, flavonoids, saponins, phenol, glycosides whereas, other phytochemicals like carbohydrates, tannins, and terpenoids showed equal concentration in methanolic root and leaf extracts. In antibacterial study, the methanolic root extract was found to exhibit a maximum zone of inhibition (33 ± 1) against E.fecalis and minimum zone (17 ± 2) against E. coli. The methanolic leaf extract showed a maximum zone of inhibition (31 ± 1) against E. fecalis and a minimum zone (18 ± 2) against K. pneumonia. The antioxidant activity of G.kurroo revealed that the methanolic extracts of root as compared to the methanolic extract of leaves showed comparatively high antioxidant activity and this is due to the presence of high phenol and flavonoid content.
