Generated by the overconsumption of sucrose, diabetes and obesity has led to consumption trends of products with low calorie natural sweeteners. Glycosides of Stevia are an alternative sweetener that has a sweetness 200-400 times greater than sucrose and also have zero calorie. These glycosides have been obtained with conventional extraction techniques that generate high energy consumption and negative environmental impact. This work identifies the most used green extraction techniques for obtaining the glycosides. Some of them like microwaves generate rapid heating due to electric and magnetic fields; ultrasound increases the area of mass transfer due to cavitation, solvents in supercritical conditions have better ability to extraction, and enzymes promote the availability of the analyte breaking the cellulose. Ultrasound presented higher yields with values of 96,46 and 36,92 (mg/g of extract) for stevioside and Rebaudioside-A, respectively. Some of the new extraction techniques based on high pressures and temperatures like the use of accelerated solvents extraction (with yields of up to 63,20 mg/g dry extract, for stevioside), are environmentally friendly technologies with the environment and they have potential industrial uses.
