Abstract:

The purpose of present research work is to investigate number and types of bioactive compounds present in Mentha spicata L. grown in north east Punjab suburban region. Most suitable technique used for this study is FTIR which is nondestructive, cost effective, user and environment friendly. Mentha spicata L. or garden mint cultivated under normal atmospheric conditions. The flowers and remaining non-flowering part were plucked and kept in under shade for 40 days to avoid photochemical changes. Flowers and non-flowering parts were grinded to fine powder and were analyzed using FTIR spectroscopi

Abstract:

Pisonia grandis is a traditional medicinal plant. It is commonly known as Leeachai kottai keerai. The present investigation focus on screening of phytochemical constituents, antioxidant activity and FT-IR analysis of Pisonia grandis leaf extracts. The leaf extracts were prepared using three different solvents (Aqueous, Methanol, Ethanol). The antioxidant potential of the extracts was assessed by employing different assays such as DDPH and ABTS. The screening tests also were performed for the presence of secondary metabolites such as alkaloids, flavonoids, terpenoids, phenols, steroids, saponin

Abstract:

Aim: The present study was expected to explore the molecular interaction of five oxidative stress (OS) associated target receptors with Alpha-Pinene and its antioxidant validation for the effective treatment of Parkinson’s disease (PD). Background: Oxidative stress (OS) via multitudinous cascades is considered to be the leading attribute to dopaminergic cell degeneration in PD. Furthermore, it is also well-linked to other mechanisms involved in the neurodegeneration process, like dysfunction of mitochondria, neuroinflammation and excitotoxicity due to NO.
