The main object of the present study was to evaluate the influence of irrigation periods on the distribution of phenolic compounds (flavonoids and phenolic acids) and tocopherols (α-, β-, γ- and δ-tocopherol) in mung bean cultivars. Each mung bean seed was treated with one of three different irrigation treatments that represented different lengths of time between irrigation events (100 mL/3 days, 100 mL/6 days and 100 mL/ 9 days) from the July 2, 2017 to the August 30, 2017. The average total phenolic compounds contents of different irrigation events (100 mL/3 days, 100 mL/6 days and 100 mL/ 9 days) were shown 2912.0 µg•g-1 (100 mL/3 days), 3321.8 µg•g-1 (100 mL/6 days) and 3002.0 µg•g-1 (100 mL/ 9 days). The tocopherols in mung bean seeds were analyzed by GC instruments. The average total tocopherol compounds of 3 different days and 100 mL/ 9 days) were shown 112.1 µg•g-1 (100 mL/3 days), 85.1 µg•g-1 (100 mL/6 days) and 93.0 µg•g-1 (100 mL/ 9 days). Among 3 different irrigation events, 100 mL/3 days water controls showed the highest levels of total tocopherols concentrations.
