Nematicidal Activity of Stevia rebaudiana (Bertoni) Assisted by Phytochemical Analysis

Optimization of ultrasound assisted extraction of functional ingredients from Stevia rebaudiana Bertoni leaves

*Corresponding author e-mail: [email protected] A b s t r a c t. The aim of the present study was to reveal an effective extraction procedure for maximization of the yield of steviol glycosides and total phenolic compounds as well as antioxidant activity in stevia extracts. Ultrasound assisted extraction was compared with conventional solvent extraction. The examined solvents were water (100oC/24 ...

Is Stevia rebaudiana Bertoni a Non Cariogenic Sweetener? A Review.

Stevia rebaudiana Bertoni is a small perennial shrub of the Asteraceae (Compositae) family that is native to South America, particularly Brazil and Paraguay, where it is known as "stevia" or "honey leaf" for its powerful sweetness. Several studies have suggested that in addition to their sweetness, steviosides and their related compounds, including rebaudioside A and isosteviol, may offer addit...

Assessment of genetic and biochemical diversity of Stevia rebaudiana Bertoni by DNA fingerprinting and HPLC analysis

The genomic DNA polymorphism and phytochemical variation of Stevia rebaudiana Bertoni was investigated by RAPD-PCR and HPLC analysis. For initial PCR screening, about hundred oligo-nucleotide primers were used to amplify the genomic DNA from three accessions of S. rebaudiana (L1 to L3). The concentration of stevioside content was quantified by using HPLC analysis. A total of 9 primers were fina...

Additional minor diterpene glycosides from Stevia rebaudiana Bertoni.

Two additional novel minor diterpene glycosides were isolated from the commercial extract of the leaves of Stevia rebaudiana Bertoni. The structures of the new compounds were identified as 13-{β-D-glucopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-oxy} ent-kaur-16-en-19-oic acid {β-D-xylopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)]-O-β-D-glucupyranosyl-ester} (1), and 1...
