Bioactive compound, polyphenol content, and antioxidant activity of Linn. root extract.

Linn. is an ethnopharmacologically important plant having extensive uses in Ayurveda, Unani, and Siddha. This study was carried out to evaluate the chemical profile of Linn.

Phytochemical screening of roots and exploring its polyphenol content and antioxidant activity.

The objective of the article is to investigate the chemical composition of roots methanolic extract and to evaluate the polyphenol content and antioxidant potential. Gas Chromatography-Mass Spectroscopy (GC-MS) and High-Performance Liquid Chromatography - Photo Diode Array (HPLC-PDA) techniques were used to characterize chemical composition of methanolic extract of roots. The GC-MS analysis extract resulted in the isolation of thirty-seven phytochemical constituents in methanol extracts.

Effect of salicylic acid elicitor on antioxidant potential and chemical composition of raised plants of Roxb. ex DC.

The present study for the first time investigated the effects of Salicylic acid (SA) (50, 100 and 200 mg/L) on growth and antioxidant capacity of . SA significantly enhanced shoot multiplication at 100 mg/L concentration. The result showed highest significant increase in antioxidant activity by 50 mg/L SA elicited plantlets in terms of DPPH (2,2-Di-phenyl-1-picryl-hydrazyl) free radical scavenging activity (IC50 32.

Chemical composition, polyphenol contents and antioxidant activities of the 'Himalayan toothache relieving tree' ( DC.).

The present study carried out to investigate the bioactive chemical compounds, total polyphenol content and antioxidant potential of different extracts of the leaves collected from the Nainital, Uttarakhand. The GC-MS analysis of leaves extract resulted in the isolation of sixty, twelve, twenty-three and nineteen phytochemical constituents in methanol, ethanol, chloroform and water extracts respectively. The leaves extracts were strongly characterised by Heneicosane, Tetratetracontane, Phytol, Fargesin, (+)- Seasmin and Paulowin.
