PRELIMINARY PHYTOCHEMICAL SCREENING OF TWO MEDICINAL PLANTS -SOLANUM NIGRUM LINN. AND LEUCAS ASPERA (WILLD.) LINN.Abstract
The medicinal plants are useful for healing, as well as, for curing of human diseases because of the presence of phytochemical constituents. Phytochemicals are naturally occurring in the medicinal plants, leaves, vegetables, and roots that have defense mechanism and protect from various diseases. The leaves of Solanum are used to treat mouth ulcers that happen during winter periods in Tamil Nadu. Leaves of Leucas are considered useful in chronic rheumatism, psoriasis, and other skin eruptions. The preliminary phytochemical screening showed the presence of almost all the phytoconstituents in the different solvent extracts used. Protein and carbohydrate were found to be absent only in chloroform, petroleum ether, and benzene extracts. The presence of various other phytoconstituents such as alkaloids, flavonoids, steroids, terpenoids, quinone, phenols, starch, cellulose, oil, and fat shows the therapeutic use of the plants both S. nigrum as well as L. aspera for accelerating the wound healing process.
