In this work, the phytochemical screening, toxicity test with BLST and antioxidant against free radicals DPPH of Toba frankincense fruit and seed extracts (STYRAX parallel to PERX) have been carried out. Secondary metabolites of the fruit are dominated by alkaloids, saponins, steroids and tannins, while in seeds, the alkaloids and terpenoids are dominated. Toxicity based on the LC50 value of fruit flesh extract n-hexane 117.91 ppm (toxic), ethyl acetate 43.15 ppm (toxic) and ethanol 16.95 ppm (highly toxic). For seeds extract n-hexane 42.22 ppm (toxic), ethyl acetate 20.12 (highly toxic) and ethanol 18.46 ppm (highly toxic). The antioxidant activity of the most toxic namely ethanol extract obtained LC50 values for fruit flesh was 150.35 ppm (moderate) and seeds was 434.04 ppm (weak). In general, the toxicity of fruit is higher than seeds and based on toxicity and antioxidants activity, fruit extracts have the potential as drugs, by further studying the antibacterial bioactivity properties. © 2025 Asian Publication Corporation.
