Background: Oroxyulum indicum (OIE) is a native medicinal plant that has been widely employed in Ayurvedic medicine for thousands of years. Though studies have been published citing the analgesic and anti-inflammatory activity of Oroxyulum indicum and chrysin and Baicalein, there has been no comparative study comparing their activittes and confirming them with molecular docking results. Molecular docking study of two phytochemicals Chrysin (PubChem CID 5281607) and Baicalein (PubChem CID 5281605) into the active sites of cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2). Evaluation and validation of Anti-inflammatory and Analgesic effects of a methanolic extract of the stem bark of Oroxylum indicum and its two constituents Chrysin and Baicalein in Charles foster rats with analysis of the phytoconstituent of Oroxyulum indicum through HRMS analysis. Methodology: UHPLC-HRMS/MS analyses were performed on a Dionex Ultimate 3000 RS Series UHPLC system combined with a Q Exactive Plus High-Resolution Accurate Mass Spectrometry System. Hot plate and Tal flick model are used for screening of analgesic activity. TNF-alpha and IL-6 inflammatory markers were examined. Carrageenan model is used for antiinflammatory analysis. Result: Interesting results has been obtained in the docking studies of Chrysin and Baicalein with COX-1 (PDB ID: 1EQG). The hydrogen bond interaction established between the Chrysin and Baicalein with the important amino acid, includes Arg 120, Tyr 355, Ser 530, Met 522 (Figure 1). The binding free energy of the Chrysin and Baicalein with target COX-1 was found to be -7.88 and -7.26 Kcal/mol. Conclusion: There is marked reduction in the TNF Alpha expression in the OIE group which is followed by Baicalein and Chrysine. The Baicalein group shows the most marked cumulative increase in reaction time for tail flick among all the groups of the intervention group followed by Chrysine and OIE.

Introduction: Antimicrobial agents are an essential tool in reducing the burden of the infectious diseases. This study aimed to comprehensively determine the antihelmintic activity of indigenous plants found in India including Butea monosperma, Origanum majorana, Piper longum and Embelia ribes. Methodology: Additionally, the profiling of the phytochemical composition of the extracts was done. The preparation of the extract was done using Maceration method. For determination of antihelmintic activity Eisenia fetida were used. The gas chromatography-mass analysis was carried out in GCMS-QP-2010 plus system). Result and conclusion: Aqueous extracts of Embelia ribes and Origanum majorana did not show anthelmintic activity at any of the tested concentrations. Aqueous extract of Butea monosperma showed antihelmintic activity at 20 mg/ml and 10 mg/ml at 1 hour and 2-hour time interval respectively. The aqueous extract of Piper longum showed activity at concentration 20mg/ml and 10 mg/ml at the time interval of 1 hour and 3-hour respectively.
