DETERMINATION OF Cu, Fe AND Zn IN SILYBUM MARIANUM SEEDS AFTER DIGESTED USING MICROWAVE OVEN BY FAAS

Abstract

This study, the concentrations of necessary trace and microelements like Cu, Fe and Zn were determined in the Silybum marianum seeds used to medicine purpose for many years. For this intention, the digestion procedure based on closed vessel-assisted microwave oven (MW) was determined a rapid, reliable, and simple digestion method for the flame atomic absorption spectrophotometric (FAAS) analysis of herbal plant. Various periods for different powers and acid mixture of the MW were examined. The obtained data show that the MW is an excellent method because it is fast and results in fewer losses and contaminants. The metal concentrations were of Fe>Cu>Zn for herbal seed, respectively.

SILYBUM MARIANUM TOHUMLARINDA FAAS İLE MİKRODALGA FIRIN KULLANILARAK ÇÖZÜNÜRLEŞTİRMEDEN SONRA Cu, Fe ve Zn TAYİNİ

Abstract

Bu çalışma, uzun yıllardır ilaç olarak kullanılan Silybum marianum tohumlarında gerekli olan Cu, Fe ve Zn gibi eser elementlerin konsantrasyonları belirlenmiştir. Bu amaçla, tıbbi bitkinin alevli atomik absorpsiyon spektrofotometrik (FAAS) analizi için kapalı sistem destekli mikrodalga fırına (MW) dayalı çözünürleştirme prosedürü hızlı, güvenilir ve basit bir çözünürleştirme yöntemi olarak belirlenmiştir. MW'nin farklı güçleri ve asit karışımı için çeşitli periyotlar incelenmiştir. Elde edilen veriler, MW'nin hızlı olması ve daha az kayıp ve kirletici ile sonuçlanması nedeniyle mükemmel bir yöntem olduğunu göstermektedir. Tıbbi tohum için metal konsantrasyonları sırasıyla Fe>Cu>Zn idi.
