Fast isocratic HPLC method for the separation of steviol glycosides from Stevia rebaudiana Bertoni, used as sweeteners in the food industry. The separation is performed on an ASTRA(R) C18-HE column, 3 um, 150 mm x 4.6 mm, part number AST-5732-IK46. Mobile phase: acetonitrile + 0.1% formic acid : water (32 % : 68 % v/v), isocratic elution. Flow rate 1.6 mL/min, temperature 65 C, UV detection at 210 nm; the injection volume is not stated in the document. Analytes are 1 rebaudioside D, 2 rebaudioside A and 3 stevioside; no CAS numbers are given in the note. The single chromatogram shows the standard on the ASTRA(R) C18-HE column, with all peaks eluting within roughly 4.5 minutes (rebaudioside D at about 1.7 min, rebaudioside A at about 4.1 min and stevioside at about 4.4 min) after…
