Abstract
Total Polyphenols and DPPH Free Radicals Scavenging Activity of Six Leafy Vegetables of Bangladesh: Vegetables are the most important sources of essential bioactive compounds providing health benefits.It is also cheap and available in most of the country. To seek out the potential cheap sources of dietary bioactive compounds, ethanol extracts of six commonly consumed Bangladeshi leafy vegetables were screened for polyphenols and DPPH free radical scavenging activity. Among the extracts, Lagenaria siceraria showed the highest total polyphenol content (21.45 mg gallic acid equivalent (GAE)/g extract), followed by Basella alba (15.51 mg GAE/g) and Coriander sativum (14.37 mg GAE/g) whereas Centella asiatica showed the lowest polyphenol content (9.62 mg GAE/g extract), aftreward Chenopodum album (12.93 mg GAE/g) and Pisum sativum (13.17 mg GAE/g). Pisum sativum showed the most potent DPPH free radical scavenging activity with an IC50 76.64 μg/ml subsequently Lagenaria siceraria 123.78 μg/ml. From the given results it can be concluded that Pisum sativum followed by Lagenaria siceraria are most potential sources of antioxidants among the six leafy vegetables.
