Madhuca longifolia (M. longifolia) is also known as Mahua belonging to the family sapoteace family. M. longifolia is used in traditional and folklore system of medicine widely across India, Nepal, and Sri Lanka for its various pharmacological properties as in snake bites and in diabetes. Phytochemicals studies documented the different bioactive constituents, namely, glycosides, flavonoids, terpenes and saponins. The pharmacological studies proved that it possess wide range of biological activities such as antiulcer, antiinflammatory, antioxidant and antidiabetic activities. The toxicity studies reveal its non-toxic effect even at larger doses. Thus M. longifolia can be considered as a therapeutic agent for specific diseases. Scientific investigation on various isolated bioactive components and its efficacy on diseases proved the future usefulness of different species of Madhuca. This review summarizes the phytochemical, pharmacological, medicinal and non-medicinal uses of M. longifolia. Further exploration on M. longifolia for its therapeutic potential is however required for depth traditional knowledge.

Objective: To evaluate the phytochemical present in various solvent extracts from leaves of Ocimum sanctum (L.), Swertia chirayita (L.), Butea monosperma (Lam.) and Stevia rebaudiana (Bert.) as well as antioxidant and anticholinergic activities employing different in vitro models. Methods: Total phenol content of diethyl ether, chloroform and methanolic extracts obtained from leaves of different medicinal plants was determined by Folin-Ciocalteau's spectrophotometric method. Moreover, antioxidant and anticholinergic studies were conducted by four different in vitro methods which included diphenyl picrylhydrazyl radical scavenging, 2,2-azinobis (3-ethylbezoline-6-sulphonic acid), reducing activity by ferrous reduced antioxidant power and anti-acetylcholinesterase assay, in order to ensure pharmacological potential of the plants. Results: The methanolic leaf extract of Ocimum sanctum showed the highest total phenol content which was (21.13±1.04) GAE/g DW and antioxidant activities compared to other plants with the IC
