Pengaruh Tempat Tumbuh Tanaman Daun Gaharu (Aquilaria malaccensis Lam) dari Dua Daerah yang Berbeda terhadap Aktivitas Antioksidan

Where it grows can affect the content of its compounds, this will also activity test being studied. This study used gaharu leaves from two different regions, namely Palembang and Bogor. The aim was to determine antioxidant Bogor total flavonoid content. research method began with sample preparation, simplicia characterization then extracted by maceration using 96% ethanol, fractionated liquid – extraction n-hexane, ethyl acetate, methanol:water solvents. Extracts fractions were monitored TLC tested for DPPH (1,1-Diphenyl-2-Pikrihidrazil) a UV-Vis spectrophotometer where intensity determined IC50 value determination results ethanol extract, fraction, acetate n-hexane fraction respectively 47.44, 71.98, 84.30 138.81 µg/ml while extract methanol : water, 45.57, 66.39, 81.12, 140.09 µg/ml. 13.452 QE/g that 11.254 QE/g. In conclusion, is stronger in antioxidants than leaves. Directly proportional content, thought be due influence place grows, such as soil nutrient temperature, climate, sunlight intensity.
