Herbal drugs are traditionally used in various parts of the world to cure different diseases. The Ayurvedic and Siddha medical systems are very famous medical practices in Indian traditional medicines. Over the last few ,researcher have aimed at identifying and validation plant derived substance for the treatment of various disease .similarly it has been already proved that various parts of plants such as leaf, fruits seeds etc.provide heath and nutrition promoting compounds traditional used against various disease. Aegle marmelos have been used in ethno medicine to exploit its’ medicinal properties including astringent, antidiarrheal antidysentric, demulcent, antipyretic, and anti-inflammatory activities. The present review aims to complete medicinal values of Aegle marmelos generated through the research activity using modern scientific approaches and innovative scientific tools.

Aegle marmelos is a slow-growing, medium sized tree, up to 12-15 m tall with short trunk, thick, soft, flaking bark, and spreading, sometimes spiny branches, the lower ones drooping. Young suckers bear many stiff, straight spines. A clear, gummy sap, resembling gum Arabic, exudes from wounded branches and hangs down in long strands, becoming gradually solid. It is sweet at first taste and then irritating to the throat. The deciduous, alternate leaves, borne singly or in 2's or 3's, are composed of 3 to 5 oval, pointed, shallowly toothed leaflets, 4-10 cm long, 2-5 cm wide, the terminal one with a long petiole. New foliage is glossy and pinkish-maroon. Mature leaves emit a disagreeable odor when bruised. Fragrant flowers , in clusters of 4 to 7 along the young branch lets, have 4 recurved, fleshy petals, green outside, yellowish inside, and 50 or more Greenish-yellow stamens. The fruits are round, pyriform, oval, or oblong, 5-20 cm in diameter, may have a thin, hard, woody shell or a more or less soft rind, gray-green until the fruit is fully ripe, when it turns yellowish. It is dotted with aromatic, minute oil glands. Inside, there is a hard central core and 8 to 20 faintly defined triangular segments, with thin, dark-orange walls, filled with aromatic, pale orange, pasty, sweet, resinous, more or less astringent, pulp. Embedded in the pulp are 10 to 15 seeds, flattened oblongs, About 1 cm long, bearing woolly hairs and each enclosed in a sac of adhesive, transparent mucilage that solidifies on drying 2

It has a firm leathery texture, a sweet taste and fracture is fibrous. Stream bark is extremely gray and internally cream in colour. The outer surface is rough warty due to a number of lenticels, ridges and furrows. It is 4-8 mm thick, film in texture and occurs as flat or channeled pieces6. The fracture is tough and gritty in outer region and fibrous in the inner.5The taste is sweet and there is no characteristic odour5.
Various chemical constituents were found in bael like alkaloids, coumarins, steroids, polysaccharides, tannins, carotenoids etc.
Agelin, aegelenine, marmeline, dictamine, fragrine, O-methylhalfordinine, O-isopentanylhalford iniol, N-4-methoxy styryl cinnamide.
Marmelosin, marmesin, imperatorin, marmin, alloimperatorin, methylether, xanthotoxol, scoparone, scopoletin, umbelliferone, psoralen and marmelide.
Galactose, arabinose, uronic acid and L-rhamnose was obtained on hydrolysis.
Tannin was also present in leaves and fruit as skimmianine. Carotenoids were also reported, which import pale colour to fruit
Composed of palmitic, stearic, oleic, linoleic and linolenic acid. The fruit pulp contains 60.7 per cent moisture. The pulp contains 0.46 per cent acidity, 8.36 per cent total sugars, 6.21 per cent reducing sugars, 2.04 per cent non-reducing sugars and 0.21 per cent tannins. The pectin content is 2.52 per cent, which is quite high. The fruit pulp, however, is not a good source of vitamin C which is only 920 mg per 100 g of pulp4. This fruit is a very good source of protein which is 5.12 per cent of the edible portion. The total mineral content of the edible portion, as represented by ash, is 2.663 per cent. The percentage content of some of the minerals, viz. phosphorus, potassium, calcium, magnesium and iron is 0.137, 0.746, 0.188, 0.127 and 0.007 respectively.6, 7, 8
