The greenhouse study was conducted to determine the phytochemical compound, total flavonoid content (TFC), and antioxidant activity on different plant organs and ages. The tests were performed on fresh leaves, senescent leaves, unripe fruit, ripened fruit, and stem at 6, 9, and 12 months old after planting (MAP). The results showed that the phytochemical compound different indifference organs and ages. The older age of the plant, the more types of the phytochemical compound found within each plant organ. At 6 and 9 MAP, the highest flavonoid content was found in senescent leaves extract and the lowest found on the stem. Whereas at the 12 MAP, the highest TFC was found on senescent leaves extract followed by ripened fruit, fresh leaves, unripe fruit, and stem. Antioxidant activity in all organs studied increased with increasing age of the plant. Based on IC50 values, at 12 MAP, the highest antioxidant activity was obtained on senescent leaves, followed by fresh leaves, ripened fruit, unripe fruit, and the lowest on the stem. The result of the present study showed that the senescent leaves extract has the highest total flavonoid content and antioxidant activity at 12 MAP as compared to fresh leaves, unripe fruits, ripened fruits, and stem.
