ABSTRACT
Objective: To explore antioxidant potential, anti-cancer activity, and phytochemicals of Commelina benghalensis L. Methods: The roots of Commelina benghalensis were extracted in different solvents (methanol, ethanol, benzene, chloroform, n-hexane) with a range of polarity. Antioxidant activity was evaluated by reducing power assay, DPPH radical scavenging activity and phosphomolybdenum method, cytotoxicity by MTT assay, apoptotic and cell cycle analysis by flow cytometry, migratory and invasive potential by wound scratch assay and invasion assay, respectively, functional groups analysis by FT-IR spectroscopy and phytochemicals by aluminum chloride colorimetric and Folin-Ciocalteu methods. Results: The extracts showed worthy antioxidant potential. The chloroform extract demonstrated the most significant cytotoxic effect on MDA-MB-231 (breast cancer) cell line, induced apoptosis and reduced migratory and invasive potential of MDA-MB-231 cells. Methanol and ethanol extracts presented good yield of total phenolic and total flavonoid contents. The FTIR spectroscopic studies revealed different characteristic peak values with various functional compounds such as alkenes, alkanes, aliphatic amines, aromatics, alkyl halides, carboxylic acid, alcohols, ester, aldehydes and ketones. Conclusions: The results demonstrate the potential use of Commelina benghalensis as a good antioxidant with significant anti-cancer effect.
ABSTRACT
Fragaria × ananassa leaves extracts prepared in different solvents were subject for antioxidative, cytotoxicity, protein kinase inhibition and antibacterial activities. The extracts showed varying activities depending upon solvent used for extraction. Combined effect of methanol and ethyl acetate showed maximum antioxidant and reducing power potential [207.65+/-6 micro g AAE/mg and 88.58+/-20 micro g AAE/mg, respectively]. Maximum DPPH [2,2-diphenyl-1-picryl hydrazyl] free radical scavenging activity was calculated by when methanol: chloroform and acetate fractions were used [87.68% and 86.88% inhibition, respectively]. Total phenolics varied from 186 to 1.91 micro g AAE/mg while total flavonoids also significantly varied among the extracts. The extracts also showed significant activities against brine shrimp larvae and bacterial strains tested. The study concludes that Fragaria × ananassa leaves can be a good source for isolation of active phytochemicals to be used in different industries
