Abstract
Santol (Sandoricum koetjape) fruit was low in calories and deficient in vitamins B1, B2, and C, but it is a rich source of potassium, containing 156.05-188.48 mg per 100 g. The first filial (F1) generation was observed on the 3rd day after emergence, and survival rates exceeded 90% at all concentrations. In climbing assays, a 100 mg/mL concentration reduced climbing speed over a 10 cm distance by 9.35 times in the P generation and 7.74 times in the F1 generation compared to control. At this concentration, the adult emergence rate decreased to 53%, and body weight in both generations was reduced. However, no difference in body weight was observed at concentrations of 20, 40, 60, and 80 mg/mL compared to controls. These findings indicated that santol fruit is a good source of potassium, but high concentrations of santol extract negatively impact the health and performance of D. melanogaster.
