Abstract

The fruits and seeds of the cherry laurel (Laurocerasus
officinalis Roem.) are utilized as traditionally in Turkey
for the treatment of stomach ulcers, digestive system
problems, bronchitis and eczemas, as well as a diuretic
and anti-diabetic agent. The aim of this study was to
determine the content of essential element and toxic
metal in cherry laurel fruit and seed. For this purpose,
firstly the dried fruit and seed materials were digested
with nitric acid (10%) in microwave digestion unit for
10 min. Then, the content of elements in digested samples was identified by using inductively coupled plasma
mass spectrometry (ICP-MS). Our results showed that
the fruit and seeds of cherry laurel contained plentiful
major essential elements such as K, Mg, Ca, and Na and
essential trace elements such as Fe, Cu, Zn, Ni, Mo, Co
and Cr, which are necessary for human health. However,
the toxic metals such as Hg, Cd, As, Pb, Ag, and Al were
not detected in the samples. In conclusion, cherry laurel
might be used as a source of natural mineral supplementation.

Karayemiş (Laurocerasus Officinalis Roem.) Meyvesi ve Tohumlarının Esansiyel Element ve Metal İçerikleri

Abstract

Karayemiş’in (Laurocerasus officinalis Roem.) meyve ve
tohumları, Türkiye’de geleneksel olarak mide ülserleri,
sindirim sistem problemleri, bronşit ve ekzama tedavisi
ya da diüretik ve anti-diyabetik ajan olarak kullanılmaktadır. Bu çalışmanın amacı, karayemiş meyve ve tohumlarında bulunan esansiyel element ve metal içeriğinin
belirlenmesidir. Bu amaçla, ilk olarak kurutulmuş
meyve ve tohum örnekleri mikrodalga yakma
ünitesinde 10 dk. nitrik asit (%10) ile yakıldı. Sonra,
yakılan örneklerdeki elementlerin içeriği indüktif eşleşmiş plazma kütle spektrometresi (ICP-MS) ile belirlendi.
Sonuçlarımız, karayemiş meyve ve tohumunun insan
sağlığı için gerekli olan çok sayıda K, Mg, Ca, Na, gibi
majör esansiyel elementler ile Fe, Cu, Zn, Ni, Mo, Co, Cr
gibi esansiyel eser elementleri içerdiğini gösterdi.
Bununla birlikte, örneklerde Hg, Cd, As, Pb, Ag ve Al gibi
toksik metaller tespit edilmedi. Sonuç olarak karayemiş
meyve ve tohumları doğal mineral takviyesi kaynağı
olarak kullanılabilir.
