Abstract:
The plant derived materials come into use in the contemporary medicine through aboriginal cure in
traditional systems of medicine. Medicinal plants are chief antidote for numerous diseases and have been
used since time immemorial. The present study was investigated to identify the preliminary phytochemical
analysis of crude extracts of leaves, fruits and stem of Datura stramonium using aqueous, benzene &
CCl4 as solvents and in vitro antioxidant activity of dry and fresh leaves of D. stramonium L. by using
DPPH methods. The extracts were subjected to qualitative phytochemical screening using standard
procedures. Three different extracts of leaves, stem and fruits of D. stramonium were found to contain
various secondary metabolites like Triterpenoids, Steroids, Glycosides, Saponins, Alkaloids, Flavonoids
and Tannins. The results of antioxidant properties of both fresh and dry extracts exemplified that aqueous
has more potent free radical scavenging activity than the organic solvents; the absorbance of the
prepared samples was measured using UV- visible spectroscopy at 520 nm wavelength. The
phytochemicals generated data from the three crude extracts of D. stramonium may be used as tools for
quality control of drugs in the future, for the healing of a diversity of disease conditions
