Okra fruit (Abelmoschus esculentus (L.) Moench) is a vegetable that contains polyphenol, carotenoid, flavonoid, and vitamin. The contains of okra fruit can be antioxidants. One of the Antioxidants contens is affected by the harvesting age. Late harvesting si affected for fruit texture, so it will determine that okra fruit be able consumed as a vegetable. This research intends to knowing the effect of different harvest age on antioxidant activity and knowing the best harvest age on the harvest of okra fruit for a vegetable consumption. This research used non-practical complete randomized design (CRD) with 8 treatments, specifically P1 (harvesting three days after flowering), P2 (harvesting four days after flowering), P3 (harvesting five days after flowering), P4 (harvesting six days after flowering), P5 (harvesting seven days after flowering), P6 (harvesting eight days after flowering), P8 (harvesting ten days after flowering). Harvesting six days after flowering for red okra is the best treatment for vegetable consumption by total antioxidant activity value 87.
