Abstract:
A medicinal plant is any plant in which one or more of its organs contains substances
that can be used for the therapeutic purposes or which contain sources of ingredients that
can be used in the synthesis and production of use full drugs. Drynaria Volkensii is one
of the vascular epiphytic plant, families of polypodiaceae that is traditionally used to
treat tooth ache. This research work is focused on phytochemical screening, structural
elucidation and antibacterial activity of Drynaria Volkensii rhizomes extracts.
Phytochemical screening of the rhizome of Drynaria volkensii extracts obtained from
maceration and Soxhlet methods confirms the presence of many phytochemicals. The
methanol, chloroform and hexane extract of the rhizome of Drynaria volkensii also tested
for their anti-bacterial activity toward against staphylococcus aurous, Klebsiella
pneumonia and Pseudomonas aurogenas. The methanol extracts obtained from
maceration method showed good zone of inhibition against the three bacterial strains
followed by methanol extracts obtained from Soxhlet methods. The chloroform extracts
obtained from maceration and Hexane extracts obtained from Soxhlet methods undergo
thin layer chromatography to set the sample for column chromatography and solvent
selection. Finally 0.132g of chloroform extract and 0.39g of hexane extracts transported
for spectroscopic purpose. Then the structure of the sample was proposed by using
spectroscopic techniques including IR to identify the functional groups, 1H-NMR to
determine number of proton,
13C-NMR to predict the number of all protonated of carbon
and DEPT-135 to identify CH2 groups
