Determination of Rebaudioside A and Stevioside in Leaves of S. rebaudiana Bertoni Grown in México by a Validated HPLC Method
Stevia rebaudiana is a plant with high sweetening capacity due to its content of glycosides, mainly stevioside and rebaudioside A. Several techniques have been used to determine the concentrations of glycosides in Stevia, although an HPLC method is recommended by the FAO/WHO-JECFA. Varieties of Stevia have been recently grown in Mexico, with no previous report of glycosides by a validated metho...
متن کاملA Rapid Dialysis Method for Analysis of Stevioside and Rebaudioside A in Foods.
A rapid dialysis method for the analysis of stevioside (SS) and rebaudioside A (RS) in foods was developed. Minced samples (10 g) were packed into 30 cm net length dialysis tubing with 30% methanol to increase the dialysis efficiency. The dialysis tubing was put in a 100 mL centrifuge tube, and the total fluid volume was made up to 100 mL with 30% methanol. Dialysis was done with shaking while ...
متن کاملHPTLC method for simultaneous analysis of stevioside and rebaudioside-A in Stevia rebaudiana.
An HPTLC method was developed and validated for simultaneous determination of stevioside (STE) and rebaudioside-A (REB-A) in Stevia rebaudiana leaves. The HPTLC separation was performed on precoated silica gel 60F254 HPTLC plates with the mobile phase ethyl acetate-ethanol-acetone-water (15 + 3 + 6 + 6, v/v/v/v). The densitometric quantification of steviol glycosides was carried out at Amax 580...
متن کاملHPLC Determination of Glycyrrhizic and Glycyrrhetinic acids in Weiyanning granule
To establish a method for determination of glycyrrhizic and glycyrrhetinic acids in Weiyanning Granule. The contents of glycyrrhizic and glycyrrhetinic acids are determined by HPLC under conditions as follows: Diamonsil C18 (4.6 mm × 250 mm, 5 μm) column, mobile phase of acetonitrile-0.05 mol/L ammonium acetate solution (A: 0.05 mol/L ammonium acetate solution; B: acetonitrile, gradient elution...
متن کاملSimultaneous Chloramphenicol and Florfenicol Determination by A Validated DLLME-HPLC-UV Method in Pasteurized Milk
The antibiotic residues in milk are a well-known serious problem and pose several health hazards to consumers. We have described a simple, rapid, and inexpensive DLLME-HPLC/UV technique for the extraction of chloramphenicol and florfenicol residues in milk samples. Under the optimum conditions, linearity of the method was observed over the range 0.02-0.85 µg/L with correlation coefficients > 0....
