ESSENTIAL ELEMENT AND METAL CONTENT OF CHERRY LAUREL (LAUROCERASUS OFFICINALIS ROEM.) FRUIT AND SEEDS
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
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.
