DETERMINATION OF QUALITY PARAMETERS AND TEST ANTIOXIDANT ACTIVITIES OF 70% ETHANOL EXTRACT OF SEROJA LEAVES (NELUMBO NUCIFERA GAERTN.)

Objective: The purpose of this study was to evaluated the quality parameters and analyzed antioxidant activity seroja leaves Nelumbo nucifera Gaertn.
 Methods: quantification chemical compound determined by its total phenol flavonoid levels. evaluate comparability four common radical scavenging assays using 2,2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS); 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical; cupric ion reducing capacity (CUPRAC); ferric power (FRAP); 2-thiobarbituric (TBA) methods.
 Results: results phytochemical screening for simplicia powder 70% ethanol extract contain secondary metabolites alkaloids, flavonoids, saponins, tannins, coumarin, quinones, triterpenoid steroids. determination meet requirements safety standard medicinal herb. result content from Seroja 181.62±0.82 mg GAE/g extract. levels amounted 289.83±1.04 QE/g tests ABTS, DPPH, TBA methods showed IC50 respectively 287.7 mg/l, 22.3 352.6 mg/l CUPRAC FRAP had an 160.76±0.35 253.36±0.48 AAE/g extract.
 Conclusion: (Nelumbo Gaertn.) have potential be used as herb control safety.
