Abstract
Boron content of 10 grape ( Vitis vinifera) varieties was determined by using Azomethine H spectrophotometric method. The grape samples have been taken from Adana and Nigde region of Turkey. The results varied between 0.59 and 9.51 mg.kg -1 . Consequently, the differences have been found in boron content of five regions’ (Kamisli, Armutlubag, Bozyer, Bagalti, Catiliyer) grape varieties. The highest boron content was in Armutlubag region. Results revealed that the Turkish grape is a good natural source of boron.
Highlights
Boron is one of the trace elements in nature, occurring only in minute concentrations in natural systems
The absorption spectra of azomethine H are measured against the reagent blank (Fig.1.)
As the maximum absorption of azomethine H is found at 412 nm, the wavelength of 412 nm was chosen for the spectrophotometric determination of boron in the samples
Summary
Boron is one of the trace elements in nature, occurring only in minute concentrations in natural systems. In literatures a number of methods have been reported to determination of boron [10] such as spectrophotometry, potentiometry, chromatography, flame atomic emission and absorption spectrophotometry, ICP-OES, ICP-MS, mass spectrometry (MS) and neutron activation analysis [7]. Among all these methods, colorimetric and ICP-OES methods have been extensively applied B determination in plant samples. ICP-OES and spectrophotometric Azomethine H method methods have been applied for determination of boron in hazelnut. Azomethine H spectrophotometric method was used for determination of boron in grape with seed. It has been purposed that boron content of the same plant in different regions is compared in this study
