Abstract
The purpose of this study was to determine the content of bioactive compounds, chemical content and antioxidant activity of karamunting fruit. The dietary fiber content of 100 grams of karamunting fruit is 83.37%, vitamin E (alpha-tocopherol) 10.25 mg/100 fresh fruit, lipids (2.96% of the RDI) with the predominant fat being linoleic acid (67.25% of total fatty acids), and sugar (6.25% of the RDI). TPC (Gallic Acid Equivalent)/total phenol 12.05 mg/100 g, total anthocyanins 3.63 mg/gram, total flavonoids 23.51 mg QE/gram, every 100 grams of karamunting fruit contains 4.6 grams of protein, and antioxidant (Inhibition Concentration 50) 1,028 (μg/ ml) is categorized as very strong, and 33 bioactive compounds. The karamunting plant that grows on Tarakan Island, North Kalimantan Province-Indonesia, which so far has no economic value and is underutilized, is proven to contain bioactive compounds that have very high antioxidant values, besides that they also contain high dietary fiber, essential fatty acids, and beneficial phenolic compounds. for health. In karamunting fruit, 33 bioactive compounds were also found, and 17 of them were new bioactive compounds that had not been discovered by previous researchers.
