Phytochemical Evaluation And In Vitro Study Of Antioxidant Potency Of Amorphophallus Campanulatus, Alocasia Indica And Colocasia Esculenta: A Comparative Analysis
lessThan i greaterThan Amorphophallus campanulatus, Alocasia indica lessThan /i greaterThan and lessThan i greaterThan Colocasia esculenta lessThan /i greaterThan are very popular for their edible corms and leaves, especially in Assam and Bengal and are cultivated there as common food crops. Besides, they are also considered as medicinal plants in Sushruta Samhita and Ayurveda. So, the ethanolic extracts of these tubers were screened for the presence of in vitro antioxidant potential against 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical, ferric reducing power, hydroxyl radical and superoxide radical. Total phenolic and flavonoid contents of all the extracts were also evaluated. The results revealed that the ethanolic extracts of all the tubers possessed antioxidant property. Among the three, lessThan i greaterThan Amorphophallus campanulatus lessThan /i greaterThan showed significantly higher (P lessThan 0.01) antioxidant potential in scavenging free radical than that of lessThan i greaterThan Alocasia indica lessThan /i greaterThan and lessThan i greaterThan Colocasia esculenta. lessThan /i greaterThan This higher ability to scavenge free radicals by lessThan i greaterThan Amorphophallus campanulatus lessThan /i greaterThan may be attributed to the presence of higher amount of polyphenols and flavonoids in it, than the other two tubers as evidenced from our result lessThan i greaterThan . lessThan /i greaterThan Thus the ethanolic extracts of these tubers can be utilized in future as therapeutic agent against free radical induced oxidative stress.
