stevioside structure

Stevioside

Stevioside is the main sweetener with rebaudioside A found in the leaves of Stevia rebaudiana a plant originating in South America Dried leaves as well as aqueous extracts have been used for decades as a sweetener in many countries notably in Latin America and Asia (Japan China) [3]

Stevia rebaudiana

Structure of steviol isosteviol and stevioside The structure stereochemistry and absolute configuration of steviol and isosteviol were established through a series of chemical reactions and correlations over 20 years after the pioneering work of Bridel and Lavieille (Mosettig and Nes 1955 Dolder et al 1960 Djerassi et al 1961 Mosettig

Stevioside

Stevioside the most abundant sweet constituent present in the leaves of Stevia rebaudiana was first isolated in impure form in the first decade of the 20th century (Bertoni 1905 1918) but the final chemical structure was determined 60 years later by Mosettig et al (1963)

Life With Stevia: How Sweet It Is!

This is remarkable progress considering that as recently as 1921 scientists were just getting around to naming the main constituent (stevioside) and the molecule wasn't even accurately described until 1931 when scientists reported it to be a white crystalline hygroscopic powder approximately 300 times sweeter than cane sugar 5 And it wasn

Steviol

Steviol is a diterpene found in the leaves of Stevia rebaudiana a member of the sunflower family that is native to Paraguay and Brazil For centuries natives of those countries have used its leaves as a sweetener E Mosettig and W R Nes at the National Institutes of Health (NIH Bethesda MD) produced it in the lab using enzymes to hydrolyze its glycoside stevioside in 1955

Steviol glycoside

Structure The diterpene known as Steviol is the aglycone of stevia's sweet glycosides which are constructed by replacing the bottom hydrogen atom (see figure) with glucose and replacing the top hydrogen atom with combinations of glucose and rhamnose The two primary compounds stevioside and rebaudioside A use only glucose: stevioside has two linked glucose molecules at the top hydrogen
