Antioxidant Profiling and Antibacterial Activity of the Vaccinium sikkimense from the Lachen Valley of the Sikkim Himalayas

Vaccinium sikkimense under the family of Ericaceae is a low bush blueberry commonly found in Northern area of Sikkim Himalayas. The berry, leaves and the twigs of the plant were collected shade dried and grounded. The solvent extraction of the dried powder of the leaves, berry and the twigs and the fresh berry was carried out in different solvents to get a semi solid extract which was used for further studies like antibacterial activity against E.coli, P.aeruginosa, Klebsiella pneumoniae and S.aureus by well diffusion method where percentage inhibition was calculated using the formula and the graph was plotted. studies of the extract was carried out by DPPH method using UV/Vis spectrophotometer and the percentage scavenging activity of the reading was calculated using the formula and IC₅₀ value was calculated.
