- W2906821389 abstract "The biosynthesis of nanoparticles from plants is one of the current and emergingresearch in food technology. Mangosteen (Garcinia mangostana L.) has beenfound to contain various secondary metabolites such as prenylated andoxygenated xanthones. The aim of this research was to synthesize nanoparticlesfrom mangosteen pericarps and seeds using different types of pure polar solvent;methanol, ethanol and acetone. The extracts were analyzed for the extractionyield, amount of dry matter, total phenolic and flavonoid content, and the freeradical scavenging activity to assess the effect of solvent. The extracts were thenused for the synthesis of zinc oxide nanoparticles (ZnO-NPs), and then furtheranalyzed for the amount and free radical scavenging activity. Results show thatZnO-NPs synthesized from mangosteen pericarps extracted by methanol had thehighest yield of ZnO-NPs (103.8016%g±0.1595) and free radical scavengingactivity of 41876.77 g/mL±401.32 with size of 22.32 nm. There was no significantdifference after calcination since the free radical scavenging activity decreased astemperature increases. However, the best temperature was 100oC since itproduced the highest free radical scavenging activity (71054.96 g/mL±3.09),compared to 300oC and 500oC, with size of 29.82 nm" @default.
