Rebaudioside A

Rebaudioside A

Rebaudioside A is a compound found in stevia extract that has a high sweetening power and can be quantified using HPLC with a UV-visible detector. It, along with stevioside, has the potential to be a non-caloric alternative sweetener to sucrose for individuals with diabetes, phenylketonuria, and obesity.From: Modeling of solute transport inside plant tissue during osmotic dehydration of apple [2022], Terpenoids Against Human Diseases [2019]

Stevia rebaudiana (Asteraceae) is a perennial shrub native to South America, known worldwide for its sweet leaves. The first studies with this plant were performed by Moisés Santiago Bertoni in Paraguay, in 1887, and it is called by the local Tupis-guaranis indigenous people ‘Yerba de Paraguay’ or ‘Yerba Dulce’ and is used as a natural sweetener (Filho, 2003). Stevioside was first isolated in the early 1900s, mixed with other glycolyzed diterpenes. Together with rebaudioside A, they represent an enormous potential substitute for sucrose—because of the intense taste a non-caloric way—as an alternative sweetener to people with diabetes, phenylketonuria and obesity (Geuns, 2003; Gupta et al., 2016).

Stevia content was analyzed through the compounds with greater sweetening power in stevia extract: stevioside and rebaudioside A. The quantification of stevioside and rebaudioside A was performed with a HPLC (Perkin Elmer Flexar) with manual injector and a UV-visible Flexer detector at a wavelength of 210 nm. A C18 column (Thermo Scientific 250 mm × 4.6 mm) was used injecting a volume sample of 20 μL. A software (Chromera) was used to acquire the data. The chromatographic separation was performed in isocratic form using as mobile phase acetonitrile (ACN): water (65:35 v/v) and at a flow rate of 1 mL/min.
