Heavy Metal Content Screening in Leaves and Flowers of Hypericum origanifolium Willd. by Atomic Absorption Spectrometry

Abstract

Atomic absorption spectrometry facilitates the reliable determination of mineral content during pharmaceutical quality control of medicinal plants. In the present work, measurable amounts of Fe, Ca, Cu, K, Mg, Mn, Na and Zn were detected in the leaves and flowers of Hypericum origanifolium Willd. through atomic absorption spectrometry. Mean heavy metal content in the flowers and leaves of H. origanifolium was, in descending order, Ca > Mg > K > Na > Fe. Ca was present in higher concentrations in the flowers (11157.24 ppm) and leaves (20132.24 ppm) of titled plant. Our results reveal that flowers are less suitable as target plant parts for metal accumulation than leaves.

Hypericum origanifolium’un yaprak ve çiçeklerindeki ağır metal içeriğinin atomik absorpsiyon spektrometresi ile belirlenmesi

Abstract

Atomik absorpsiyon spektrometresi, tıbbi bitkilerin farmasötik kalite kontrolü sırasında mineral içeriğinin güvenilir bir şekilde belirlenmesini kolaylaştırmaktadır. Bu çalışmada, Hypericum origanifolium Willd'un yaprak ve çiçeklerinde atomik absorpsiyon spektrometresi ile ölçülebilir miktarda Fe, Ca, Cu, K, Mg, Mn, Na ve Zn bulunduğu tespit edilmiştir. H. origanifolium'un yaprak ve çiçeklerindeki ortalama ağır metal içeriği sırasıyla Ca> Mg> K> Na> Fe olarak belirlenmiştir. Kalsiyum, çiçek (11157,24 ppm) ve yapraklarda (20132,24 ppm) en yüksek konsantrasyonda tespit edilmiştir. Elde edilen sonuçlar çiçeklerin yapraklara kıyasla çok daha düşük seviyede ağır metal birikimi gösterdiğini ortaya koymaktadır.
