ABSTRACT
Objective: To examine the secondary metabolites present in the leaf extracts of Rhododendron arboreum Sm. ssp. nilagiricum (Zenker) Tagg. Methods: Phytochemical screening of the leaf extract was done to determine the phytochemical constituents in the various solvents studied.Results:nilagiricum (Zenker) Tagg. confirm the existence of secondary metabolites such as phenols, saponins and tannins. Conclusions: The study suggests that the leaf extracts of R. arboreum Sm. ssp. nilagiricum (Zenker) Tagg. can be best utilized in developing bioactive compounds against pathogenic infection. The phytochemical study carried out on the leaf extracts of R. arboreum Sm. ssp.
ABSTRACT
Objective: To evaluate the phytochemical properties of Azolla pinnata R. Br., Marsilea minuta L. and Salvinia molesta Mitch. Methods: The dried and powered leaves materials (50 g) were extracted successively with 250 mL of petroleum ether, ethyl acetate, methanol, chloroform, acetone, benzene and water by using Soxhlet extractor for 8 h at a temperature not exceeding the boiling point of the solvent. Phytochemical screening of the extracts was carried out according to the standard methods. Results: Out of eighteen tested extracts, eighteen extracts showed the presence of phenolics. Next to that, fourteen extracts were illustrated their existence of tannin. Ten extracts showed the occurrence of carbohydrates in the crude extracts of the selected plants. Steroid and saponin are present in eight extracts, next to that xanthoprotein is present in six extracts, followed by flavonoid and protein which are present in five extracts. Carboxylic acid showed its presence only in two extracts. Conclusions: From the results, it can be concluded that the three plants extracts show the presence of many bioactive compounds after extensive investigation. We recommend further research on these plants to quantify the concentration of these compounds. Further work will accentuate the isolation and characterization of active principles responsible for bio-efficacy and bioactivity.
ABSTRACT
Objective: To examine the phytochemicals present in the pericarp of Crataeva magna (C. magna) (Lour.) DC. which is used as a traditional medicine by the inhabitants of Kanyakumari district. Methods: Phytochemical screening of the pericarp was done to determine the secondary metabolites in various solvents studied. Results: The phytochemical screening on the pericarp of C. magna (Lour.) DC. proved the presence of phytochemicals such as phenols, saponins and tannins. Conclusions: The findings of the present study recommended that the pericarp of C. magna (Lour.) DC. have potential antimicrobial compounds that may be of use for developing plant based drugs for various ailments.
