Phyllantus emblica L. is a native plant from Indonesia which has been shown to have biological activty as antioxidant. The maturity of a plant could affect the different types and quantities of secondary metabolites and cause differences of biological activities. The objective of this research was to compare the antioxidant activity of young and old P. emblica fruit extracts from Bandung-Indonesia. Extraction was performed using macerator with different polarity of solvents as follow: n-hexane, ethyl acetate and ethanol. The extracts were vaporated using rotavapor. The antioxidant activity was tested using DPPH assay and monitored by TLC in order to find out the existing compounds which were responsible for antioxidant activity. The results showed that the extracts from P. emblica performed antioxidant activity with IC50 values of ≤50 μg/mL. Therefore, they were classified as very strong antioxidant. IC50 value of young P. emblica fruit extract showed the smaller value than IC50 value of old P. emblica fruit extract. The strongest antioxidant activty of all P.emblica extracts was showed by ethyl acetate extract from young P. emblica and it was shown by fenol substances. As conclusion, the young P. emblica fruit extract had stronger antioxidant acivity than the old P. emblica fruit extract. © 2018 International Congress of Chemistry and Environment.
