Winged bean being a minor pulse crop has been less focused for research purposes. However, seeing at its enormous
potential as a nutrient-rich crop, a study was conducted at ICAR-IIVR, Varanasi to encourage this
underutilized legume crop. Nineteen winged bean genotypes were evaluated for their antioxidant potentiality
and phenol and flavonoids content. Two chemometric techniques (PCA and AHC) were implied to find out the
pattern of variation available for antioxidant potentiality as well as to find out the best performing genotypes.
The phenol content ranged from48.4 to 143.5 (maximumin AMBIKA-II-I)mgGAE/100 gFW, and total flavonoids
content ranged from 9.1 to 37.0 mgCE/100G FW(maximuminMWBS-16-26). In both DPPH and TEAC assay, hydrophilic
antioxidant activitywas towards higher side inAMBIKA-13-4 B (5.02 μmol TE/g FWand 3.06 μmol TE/g
FW respectively). The genotypes AMBIKAWB-II-I, AMBIKA-13-4 B and MWBS-16-26 were identified superior
based on their overall total phenolics, total flavonoids and antioxidant activities coupled with chemometric
analysis.
