The Stevia rebaudiana (Bert.) leaves are natural low-calorie sweeteners used in many products, including foods, drinks, medicines, cosmetics, and more. This study aimed to use activated charcoal to remove color, purify stevioside from Stevia leaves, and utilize the chromatographic method to confirm its identity. We developed a novel eco-friendly method to decolorize and purify stevioside from Stevia leaf. The yield of stevioside was calculated by weighing the crystallized sample following freeze-drying. The average yield is 8.13%. Ultraviolet-Visible (UV-Vis) and Fourier Transform Infrared (FT-IR) spectroscopy were performed to confirm the identification. This purified sample showed a wavelength region of 4000–650 cm-1 in the FT-IR and a UV-Vis spectrum at 206.49 nm, which referred to it as a stevioside. In HPLC, the purified samp.. View More»
