Phytochemicals including minerals, total
phenolics, total flavonoids and antioxidant capacity were
measured with ferric reducing antioxidant power and radical
scavenging capacity (2,2-diphenyl-1-picrylhydrazyl or
DPPH) in fruits of three wild/semi domesticated Momordica
species (Momordica dioica, M. subangulata subsp.
renigera and M. cochinchinensis) of south east Asia. Momordica
dioica had significantly high crude protein
(1.86 g/100 g), crude fat (1.0 g/100 g), total sugar
(11.36 g/100 g), reducing sugar (9.6 g/100 g) and starch
(8.72 g/100 g) in comparison to other species. Among the
minerals analysed, phosphorus, iron and copper content
was maximum inM. subangulata subsp. renigera (0.37 %,
119.80 ppm, 10.80 ppm respectively) while magnesium
and zinc content was maximum in M. dioica (0.18 %,
37.40 ppm respectively). Interestingly, in contrast to all
other minerals, manganese content was significantly higher
in M. cochinchinensis (178 ppm). The total phenol, total
flavonoids, DPPH and FRAP values ranged from 26.08 to
106.89 mg gallic acid equivalent/100 g, 0.99–12.45 mg
catechin equivalent/100 g, 43.56–81.73 mg ascorbic acid
equivalent/100 g, 5.75–65.84 mg ascorbic acid equivalent
anti-oxidant capacity/100 g, respectively. Among the
species studied M. dioica showed the highest antioxidant
activity as it contains total phenol (106.89 mg/100 g), total
flavonoids (12.45 mg/100 g), DPPH (81.73 mg/100 g) and
FRAP (65.84 mg/100 g). From the present study, it is
concluded that these traditional vegetables may contribute
in a significant way to the food and nutritional security and
balanced diets of both rural and urban households besides
being a potential source of natural antioxidant.
