The iron nutrient content in S. tamariscina powder was 0.94 ± 0.06 mg/100 g powder, whereas selenium was present in a small amount, which showed strong antioxidant power. The total phenolic content of S. tamariscina powder was 8.65-11.61 mg gallic acid equivalents/g. S. tamariscina showed antioxidant activity in 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The ferric reducing antioxidant power of S. tamariscina powder was higher in the ethanol extract. Additionally, the ethanol extract demonstrated antimicrobial activity against Bacillus subtilis KCTC 2189. The level of high-density lipoprotein-cholesterol in the blood of ICR mice was significantly higher in the HF 20% + S. tamariscina 20% group than in the other groups (p  less then  0.05). The present study demonstrates that S. tamariscina, an abundantly existing plant, possesses antimicrobial, antioxidant, and anticytotoxic activities. S. tamariscina powder has potential as a functional food.Buah merah oil and red palm oil are red colored and unrefined edible oils. Because of this color characteristic, measuring acid value by titration method can be uncertain and subjective, so more accurate and objective methods are needed. Gas chromatography-flame ionization detector (GC-FID) and high-performance liquid chromatography-evaporative light scattering detector (HPLC-ELSD) methods were developed to determine acid value in 3 buah merah oils and 1 red palm oil by measuring free fatty acid contents. The acid value was high in the order of titration > GC-FID > HPLC-ELSD in all samples. GC-FID method showed accurate and reliable results, whereas HPLC-ELSD showed rough data partly due to the non-linear standard curve and high limit of det
