Catalytic hydrogenation of the three ent-kaurane diterpene glycosides isolated from Stevia rebaudiana, namely rubusoside, stevioside, and rebaudioside-A has been carried out using Pd(OH)₂ and their corresponding dihydro derivatives have been isolated as the products. Synthesis of reduced steviol glycosides was performed using straightforward chemistry and their structures were characterized on ...

Stevia rebaudiana Bertoni, is an ancient perennial shrub of South America, with great potential as a crop for the production of high-power natural sweetener. Due to its chemical composition and content of the phytochemical compounds, it is suitable as a raw material for the extraction and production of functional foods.

The experiment was conducted to evaluate the differences of plant growth as well as sweetener material of two types of Stevia rebaudiana under conditions of absence and presence of drought stress. In vitro, the experiment was conducted as drought traits using four levels of polyethylene glycol (0.0, 10,000, 20,000, 30,000 ppm). It was observed that survival % and No. of shoots should be conside...

A new steviol diterpene glycoside, 13-[(2-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] ent-kaur-16-en-19-oic acid-{2-O-[6-O-β-D-glucopyranosyl)-βD-glucopyranosyl]-β-D-glucopyranosyl} ester (1) has been isolated from the commercial extract of the leaves of Stevia rebaudiana Bertoni. Structure of the new compound has been established on the basis of extensive NMR spectroscopy (H &C, TOCSY, HMQC, ...

Stevia rebaudiana is a sweetener herb belongs to Asteraceae family, native Argentina, Brazil and Paraguay. has potential qualities of also constituting source many substances with nutritional effect on the human beings. The leaves stevia contain stevioside, rebaudioside, steviolbioside, isosteviol sweeter than sucrose zero calories. These steviol glycosides considered for sweet taste have comme...
