Abstract:

The nutritional and active components and antioxidant capacities of the flesh of mature fruits of Myriopteron
extensum were measured in order to evaluate its development potential as a food source. The results showed fresh fruits of
M. extensum had a water content of 90.50% and contained (11.29 ± 0.228) mg of total protein, (7.19 ± 0.129) mg of soluble
protein and (1.28 ± 0.073) mg of lipids per gram of sample. The mineral content of M. extensum was slightly lower than that
of leek and zucchini, but showed an increase compared with apple. Polysaccharide content of dry powder of M. extensum
was (36.86 ± 0.73)%. The contents of polyphenols and flavonoids were (30.52 ± 0.86) and (8.34 ± 0.24) mg/g, respectively.
Antioxidant tests suggested that the DPPH scavenging capacity of the fruit juice of M. extensum was (362.24 ± 17.89) mg
ferulic acid equivalent/g, ferric reducing power was (131.49 ± 8.34) mmol/g, total antioxidant capacity was (357.12 ± 13.11)
mg Trolox equivalent/g, and reducing power was (1 066.67 ± 24.23) μg ascorbic acid equivalent/g. M. extensum has broad
prospects for development and application due to its nutritional value and high antioxidant potential.
