This work includes the determination of moisture, ash and some antioxidants (namely, total phenols flavonoids and ascorbic acid (vitamin C)) in onion (plumps, leaves), radish (roots, leaves), and snake cucumber (fruits) located in Harran Dian, Thalab and Eber Lasloom sites in Delta Tuban, Lahij Governorate/Yemen.

Antioxidants were analyzed by Uv-Vis spectrophotometer.

The results showed significant differences in the studied vegetables.

The content of total phenols ranged between 42.79 to 79.69 ppm in the dried samples while the values of flavonoids in the dried samples were found to be within the range (46.33-100.35 ppm).

The analysis of ascorbic acid gave values between 10.51-32.56 ppm for the fresh samples.
