Tedavi
amacıyla çay olarak geniş bir kullanımı olan 9 bitki türü Van (Türkiye)'den seçilerek
Al, Fe, Mn, Zn, Ni, As, Cd, Pb, Cr, Cu, Co ve Sr seviyeleri belirlenmiştir.
Araştırmada kullanılan bitkiler: Sarı kantaron (Hypericum ssp.), civan perçemi (Achillea ssp.), hatmi (Alcea ssp), adaçayı (Salvia ssp.) ısırgan otu (Urtica ssp.), kekik (Thymus ssp), acı cehre (Frangula alnus), papatya (Matricaria ssp.) ve uçkun (Rheum ribes)'dur. Toplam olarak farklı kısımları
kullanılan 34 örnek incelenmiştir. Bitki örnekleri dört farklı satış
istasyonundan toplanmıştır. Örnekler mikrodalga yöntemi ile parçalanmış
(yakılmış) ve ICP-OES (Inductively Coupled Plasma
Optical Emission Spectrometry) spektrometre ile ölçümler belirlenmiştir.
Örneklerin mikroelement içerikleri şu şekilde sıralanmıştır: Al (0.597-32.852),
Fe (0.331-18.797), Mn (0.08-1.06), Zn (0.1-0.409), Ni (0.015), As (0.104), Cd
(0.00-0.03), Pb (0.00-0.16), Cr (0.002-0.111), Cu (0.063-0.292), Co (0.01-0.09)
ve Sr (0.107-1.925) ppm. İncelenen tıbbi bitkilerin mikro element seviyeleri
belirlenmiş ve insan sağlığı açısından güvenli olduğu sonucuna varılmıştır.

Heavy Metal Contents in Selected Medicinal Plants of Van-Turkey

Öz

Levels of Al, Fe, Mn, Zn, Ni, As, Cd,
Pb,Cr,Cu,Co and Sr were determined in selected 9 medicinal plants from
Van-Turkey, which are widely used in phytopharmacy as herbal teas. The
following plants were investigated: John’s wort (Hypericum ssp.), yarrow (Achillea ssp.), hollyhock (Alcea ssp), sage (Salvia ssp.) nettle (Urtica ssp.),
thyme (Thymus ssp), alder buckthorn (Frangula alnus), chamomile (Matricaria ssp.), rhubarb (Rheum ribes). A total of 34 samples of
various parts ofplants (root, leaf, flower) were examined. Plants were
collected from four different places in Van-Turkey. Samples were prepared using
the microwave digestion technique, and measurements were performed applying the
ICP-OES(Inductively Coupled Plasma Optical Emission Spectrometry). Contents of
microelements in the examined samples ranged: Al (0.597-32.852), Fe
(0.331-18.797), Mn (0.08-1.06), Zn (0.1-0.409), Ni (0.015), As (0.104), Cd
(0.00-0.03), Pb (0.00-0.16), Cr (0.002-0.111), Cu (0.063-0.292), Co (0.01-0.09)
and Sr (0.107-1.925) ppm. Based on determined amounts of microelements, from
investigated samples of medicinal plants are considered safe for human
consumption.
