摘要: Abstract The leaves of rosemary [Rosmarinus officinalis L. (Lamiaceae)] are extensively used as a remedy in medicine and condiment food industry. beneficial biological effects admitted to its triterpenoid fenolic acids. However, the optimal extraction conditions these acids remain unknown. aim this study was evaluate influence novel methods, their solvents on extract yield ursolic (UA), oleanoic (OA) rosmarinic (RA) from rosmarine leaves, determine relationship between content phenolic compounds obtained extracts antioxidant activities. highest UA (15.8 ± 0.2 mg/g), RA (15.4 ± 0.1 mg/g), OA (12.2 ± 0.1 mg/g) by ultrasound-assisted with 90% ethanol, 70% ethanol or water (at pH 9) maceration, respectively. Individual required increase OA, RA.
