Hindu College, Nagercoil – 629 002, Tamil Nadu Abstract The present investigation was focused on the preliminary phytochemical and Fourier Transform Infrared Spectral analysis of Rivina humilis L. The aqueous and organic solvent extract (petroleum ether, chloroform, ethyl acetate, methanol, water) were tested for availability of alkaloid, flavonoid, phenol, saponin, steroids, tannins. The FTIR spectrum showed the presence of primary/secondary amines, alkane, alkene, amino acid, nitro compounds etc. Isolation of medicinal components would however help to find new drugs. The results of this study offer a platform of using Rivina humilis as herbal alternative for various diseases. Keywords: Phytochemical screening, FTIR, Rivina humilis, methanol, functional group Introduction Plants produce bioactive molecules in a diverse range making them a rich source of different types of medicine (Kala et al., 2011; Jeeva et al., 2012; Joselin et al., 2012; Florence et al., 2012; Florence et al., 2014). Phytochemicals are bioactive chemicals of plant origin. They are regarded as secondary metabolites and they are naturally synthesized in all parts of plant body (ie) any part of the plant body contain active compounds (Criagg and David; Tiwari, 2011). Medicinal plants have recently received the attention of the pharmaceutical and scientific communities and various publications have documented the therapeutic value of natural compounds in a bid to validate claims of their biological activity (Ncubeet al., 2008). The different phytoconstituents present in medicinal plants such as flavonoid, alkaloid, phenol and tannin, carboxylic acid, terpenes and amino acids and inorganic acids (Florence et al., 2014). These phytoconstituents present specific distinctiveness and properties and it has shown protective effects against diseases without reducing their therapeutic efficacy and ISSN NO: 1301-2746 http://adalyajournal.com/ ADALYA JOURNAL Volome 8, Issue 9, September 2019 208
