INTRODUCTION Plants are natural resources of bioactive constituents used in the treatment of various disorders. The medicinal plants and their derivatives have been perceived as an essential source of therapeutically effectual medicine as they contain secondary metabolites, which are potential sources of drugs [1]. The most important bioactive constituents present in medicinal plants are flavonoids, carboxylic acids, carbohydrate, phenols, tannins, alkaloids, terpenoids, steroids and amino acids, etc. [2]. The phytochemical constituents playing a crucial role in medicines can be identified using crude extracts of the plants [3]. Plant crude extracts were containing a high amount of natural antioxidants, which are used as folkloric medicines [4]. Since ancient times, plant extracts were used in medical practices for the treatment of various ailments [5]. Aegle marmelos L. popularly known as Bael in India belonging to the family Rutaceae is an important aromatic medicinal plant that has enormous traditional uses against various diseases and many bioactive compounds have been isolated from this plant also. It is widely grown in India, tropical and subtropical countries [6]. Various parts of the Aegle marmelos L.viz. roots, leaves, stem, bark and seeds are reported to have medicinal value [7,8]. These parts are used for the treatment of a myriad ailments such as chronic diarrhoea, dysentery, peptic ulcer, inflammation and diabetes is documented [9, 10, 11, 12]. Different parts of the plants contain hypoglycaemic, hypolipidemic and blood pressure- lowering factors [13]. Several investigations reported that Aegle marmelos L. has been possessing important pharmacological properties including antioxidant, anticancer, anti-inflammatory, antipyretic, analgesic, anti-hyperglycemic and antiproliferative INDO GLOBAL JOURNAL OF PHARMACEUTICAL SCIENCES ISSN 2249- 1023 ABSTRACT: Medicinal plants are used in traditional medicine to cure various ailments. They consist of a number of bioactive components like alkaloids, flavonoids, glycosides, steroids, tannins, phenolic compounds, etc. are used for the treatment of several diseases. Aegle marmelos L. is a spiritual, religious and important medicinal plant commonly called bael. Different parts of bael used in ethnomedicine are known to possess antioxidant, antidiarrheal, antibacterial, antidysenteric, anti-inflammatory, antipyretic, analgesic activities. The aim of the present investigation is to carry screening of phytochemical constituents and Fourier Transform Infrared spectroscopic analysis of various extracts of Aegle marmelos L. leaves. The preliminary screening of phytoconstituents was carried out by standard methods. In the Aegle marmelos L. leaves the presence of phytochemicals such as carbohydrates, proteins, amino acids, steroids, alkaloids, flavonoids, glycosides, saponins, tannins were present in aqueous, acetone, ethyl acetate, dichloromethane, ethanol, methanol and petroleum ether extract. Results of the FTIR spectra of leaves extracts revealed the presence of various functional groups like alkanes, aldehydes, amides, alcohols, esters, ethers, carboxylic acids, carbonyl group, aromatic compounds, etc. All these compounds pertain to the bioactive components and could be responsible for the medicinal properties of Aegle mermelos L. © 2020 iGlobal Research and Publishing Foundation.
