Abstract

Objective: Colocasia esculenta (CE) Linn. (Family: Araceae) is an annual herbaceous plant that is known since ancient times for its curative properties. The objective of current study was phytochemical screening of chemical constituents of Colocasia esculenta  extract.


Methods: In this study methanolic and aqueous extracts of one plant namely Colocasia esculenta, were screened for the presence of phytochemical constituents and tested for their antimicrobial and antioxidant activity.


Results: TLC tests conducted revealed Rf values in the leaves for alkaloids, flavonoids, tannins, phenols and saponins (0.95-0.96-0.97-0.96-0.97) respectively. The antimicrobial activity extracts against four bacterial isolates Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Klebsiella sp. and a single fungal isolate Candida albicans with concentrations (0.5 mg/ml, and 1.0 mg/ml) of the extract were added to the disc and respective solvent was used as negative control. The antioxidative activity of leaf was evaluated by using 1,1- diphenyl-2 picrylhydrazyl (DPPH), the results showed are 86.5%, lowest from standard, ascorbic acid 87.5%.


Conclusion: The qualitative phytochemical analysis revealed the results showed presence of alkaloids, terpenoids, glycosides, resins, saponins, tannins, flavonoids, phenols, and amino acid were present in the methanol extract, with absence of glycosides, and amino acids in the aqueous extracts in leaves plant.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
