Characteristic Features and Comparative analysis of essential oil
composition of selected species of Ocimum sanctum L. through GCMS
Abstract
Background: The main aim of this research is to provide a literature of
the Ocimum plant, to know the significance of the Ocimum species carried
out by pharmacognostical study and experimental design for GC-MS.Ocimum
are very important for their therapeutic potentials. among the most
important aromatic herbs for its enormous medicinal properties. Methods:
An extreme Attention has been put on those literature reports wherein
the utilization of Tulsi and their pharmacognostical study has been done
by performing morphological and microscopic leaf and experimental design
by using essential oil by GC-MS instrumentation method Results: The
utilization of these characteristics would be important for the drug
discovery scientist to develop a specific formulation of the crude drug,
which will be a magical therapeutic agent in the future, with the many
advantageous. GC-MS chromatogram of the Ocimum sanctum, Ocimum canum and
Ocimum gratissimum oil showed major peaks and has been identified after
comparison of the mass spectra with NIST library, indicating the
presence of three phytocomponents. From the results GC-MS study
suggested that anethole which is well reported antimicrobial compound is
more in O. canum (2.66%) in comparison to O. sanctum (1,28%) but
absent in O. Gratissimum. The results indicated that the antimicrobial
activity is more in O. canum due to presence high amount of anethole in
comparison to O.Gratissimum, and O. Sanctum. The GC-MS study suggested
that anethole which is well reported antimicrobial compound is more in
O. canum (2.66%) in comparison to O. sanctum (1,28%) but absent in O.
Gratissimum. Conculsion: The result showed that microscopic character of
O. canum, with the characteristic GC MS analysis of the extracts, to
identify different species of the ocimum plant. Ocimum sanctum L. and
further experiments are required for better exploitation of essential
oil for its commercial purposes.
