Glucosylation of Steviol and Steviol-Glucosides in Extracts from Stevia rebaudiana Bertoni.
To evaluate and characterize stevioside biosynthetic pathway in Stevia rebaudiana Bertoni cv Houten, two enzyme fractions that catalyze glucosylation of steviol (ent-13-hydroxy kaur-16-en-19-oic acid) and steviol-glucosides (steviol-13-O-glucopyranoside, steviolbioside and stevioside), utilizing UDP-glucose as the glucose donor, were prepared from the soluble extracts of S. rebaudiana leaves. E...
متن کاملExtraction and characterization of steviol glycosides from Stevia rebaudiana bertoni leaves
Steviol glycosides are highly sweet diterpene glycosides found in the Paragyan shrub, Stevia rebaudiana Bertoni. Steviol glycosides, mainly stevioside and rebaudioside, principal components of Stevia rebaudiana leaf, has become well known for their sweetness and are used as non-caloric sweeteners in several countries due to their nutritional and pharmacological benefits. Hence, craving for swee...
متن کاملNitrogen Limitation Alters Biomass Production but Enhances Steviol Glycoside Concentration in Stevia rebaudiana Bertoni
The need for medicinal and aromatic plants for industrial uses creates an opportunity for farmers to produce alternative crops. Stevia rebaudiana Bertoni, a perennial shrub originating from Paraguay, is of increasing interest as a source of zero-calorie natural sweeteners: the steviol glycosides (SVglys). The aim of this study was to investigate the relevance of nitrogen (N) supply for leaf yie...
متن کاملCallusing in Stevia rebaudiana (Natural Sweetener) for Steviol Glycoside Production
Abstract—Stevia rebaudiana Bertoni (natural sweetener) belongs to Asteraceae family and can be used as substitute of artificial sweeteners for diabetic patients. Conventionally, it is cultivated by seeds or stem cutting, but seed viability rate is poor. A protocol for callus induction and multiplication was developed to produce large no. of calli in short period. Surface sterilized nodal, leaf ...
متن کاملInfluence of Extraction Methods on the Yield of Steviol Glycosides and Antioxidants in Stevia rebaudiana Extracts.
This study evaluated the application of ultrasound techniques and microwave energy, compared to conventional extraction methods (high temperatures at atmospheric pressure), for the solid-liquid extraction of steviol glycosides (sweeteners) and antioxidants (total phenols, flavonoids and antioxidant capacity) from dehydrated Stevia leaves. Different temperatures (from 50 to 100 °C), times (from ...
