This study determined the nutritional potential of Thai indigenous fruits in terms of nutrients, bioactivecompounds, and antioxidant activities. Three indigenous fruits were collected at two conservation areas in Kanchanaburi province, Thailand. The results showed that Phyllanthus emblica L. exhibited the highestlevels of vitamin C (575 ± 452 mg/100 g), total phenolics (TP) (3703 ± 1244 mGAE/100 g), and antioxidant activities, as measured by DPPH, FRAP and ORAC assays. Compared to the other two fruits, Antidesmavelutinosum Blume contained higher levels of most nutrients and dietary fibre (15.6 ± 5.9 g/100 g), as wellas carotenoids (335 ± 98 lg/100 g) and phytosterols (22.1 ± 3.9 mg/100 g). Spondias pinnata (L.f.) Kurz was high in total phenolics (3178 ± 887 mGAE/100 g) and antioxidant activity. Moreover, high correla-tions were found between TP and antioxidant activities (r > 0.9). These Thai indigenous fruits are poten-tially good sources of nutrients, bioactive compounds, and antioxidant activities. Conservation andutilisation should be promoted for food security and consumption as part of a healthy diet.
