Mixtures of S. Rebaudiana Leaves and Stems Waste for Steviosides Synthesis Using Ethanol-Water Solvents

Mixtures of S.rebaudiana leaves and stems waste were applied for steviosides synthesis. The various ethanol-water as polarity solvents were employed in the ultrasound-assisted extraction (UAE). The HPLC (High Performance Liquid Chromatography) with Eurospher 100–5NH2 column at 1mL/m3 were used for s...
