PRELIMINARY PHYTOCHEMICAL SCREENING AND IN VITRO ANTIOXIDANT ACTIVITY OF THE METHANOLIC EXTRACT OF LINDERNIA RUELLIOIDES (COLSM.) PENNELL

Objective: The objective of the study was collection of plant materials, Extraction of phytoconstituents using a different solvent, to carry out preliminary phytochemical screening of different extracted solvent, to perform fluorescence analysis, to estimate the proximate composition of the leaves Lindernia ruellioides (Colsm.) Pennell, and to determine the presence of in vitro anti-oxidant of the methanolic extract of the plant. Method: Preliminary phytochemical screening of the methanolic extract of Lindernia ruellioides (Colsm.) Pennell, estimation of proximate composition of the leaves, fluorescence analysis, total phenolic content, total flavonoids content, and in vitro antioxidant activity of the methanol extract (DPPH scavenging activity, reducing power assay, and nitric oxide scavenging activity). Results: The result of phytochemical screening of methanolic extract of Lindernia ruellioides (Colsm.) Pennell contents the presence of amino acid, flavonoids, tannins, steroids, and triterpenoids. The moisture content and Ash value were found to be appropriate and the in vitro antioxidant activity of the methanolic extract showed potential antioxidant activity in terms of DPPH scavenging activity, reducing power assay, and nitric oxide scavenging activity. Conclusion: The work presented here suggests that the methanolic extract of Lindernia ruellioides (Colsm.) Pennell possesses potential antioxidant activity

A review on global threat corona virus disease: COVID-19

Corona virus disease is a kind of viral disease caused by Severe Acute Respiratory Syndrome- CoV 2, which is first witnessed in Wuhan city, China and it can be transmit from human to human. Coronavirus size ranges from (65-125 nm) in diameter and contain a single stranded RNA as nucleic acid material, size ranging from 26 to 32 kbps in length. The sub group of coronaviruses family is Alpha (α) Beta (β) Gama (γ) and delta (δ) coronavirus. Coronavirus disease is a kind of respiratory disease which mainly affects the lower respiratory tract of human body. Initially interferon α normalisation, broad spectrum antibiotic and antiviral drugs was used to reduce the viral load. There may be different kind of mode of transmission of this virus for example Respiratory transmission, Aerosol transmission, Contact transmission and Hospital acquired transmission. There is a well explained safety measures is provided to inhibit the COVID-19 spread which should be followed properly. There are some testing processes also developed to determine the presence of this virus. Till now not even a single vaccine is developed for the treatment of this COVID-19 but more than 12 countries across the globe are undergoing trial for more than 150 vaccine candidates
