Abstract

Bay leaves are Indonesian plants, which are often used for cooking spices and have beneficial properties for human health. This study aimed to compare micronutrient and phytochemical contents in bay leaves extract with ethanol or methanol solvent. Vitamin C and tannins levels were measured using a spectrophotometer, while Fe levels used an Atomic Absorption Spectrophotometer (AAS). The results showed that bay leaves Simplicia contained 14.81±0.07 % (w/w) Fe and 29.42±3.76 % vitamin C. Higher levels of Fe, vitamin C, and tannins were also observed in ethanol extract of bay leaves (9.39 ± 0.05%, 0.15 ± 0.10 ppm, and 3,522.63 ± 39.7d3 ppm), compared to the methanol extract (5.34 ± 0.04%, 0.09 ± 0.11 ppm and 2,306.84 ± 18.98 ppm. In conclusion, ethanol is a better solvent for extracting bay leaves than methanol to obtain vitamin C, Fe, and tannins. Further research is required to confirm the anti anemia effect of that extract.
