PRELIMINARY PHYTOCHEMICAL SCREENING, TOTAL PHENOL AND FLAVONOID CONTENT OF MIMOSA RUBICAULIS AND REINWARDITA INDICA

Objective: Phytochemicals as phenol and flavonoid have a powerful biological activity. So, this study aimed to carry out phytochemical screening, total phenol and flavonoid content in two plant species i.e. M. rubicaulis and R. indica. Methods: The extraction of different parts of two plant species was done by maceration using ethanol. Phytochemical screening was done to confirm the presence of phytochemicals. Total phenol content was done by Folin ciocalteu method and total flavonoid content was done by Aluminium chloride colorimetric method. Results: Phytochemical analysis revealed the presence of flavonoid, phenol, terpenoids in both plant species. The highest concentration of phenol content was observed in the root and stem of an extract of M. rubicaulis i.e. 281.83±1.98 mg GAE/g dry extract weight and 225.37±0.60 mg GAE/g dry extract weight. The highest concentration of flavonoid contents was observed in the leaves of R. indica i.e. 462.21±4.67 mg QE/g dry extract weight followed by stem and root of M. rubicaulis i.e. 381.06±5.23 mg QE/g dry extract weight and 337.43±1.39 mg QE/g dry extract weight. Conclusion: Phytochemical analysis concluded the presence of biologically important phytoconstituents like flavonoid and phenol in both plant species. Further studies, should be carried out to isolate specific chemical constituents and should be used in different studies to explore their biological effects.
