It can be said that Loranthus europaeus growing in Turkey is poor in terms of asparagine, serine, glycine, glutamine, alanine, proline and tyrosine, on the other hand aspartic acid found to be lowest in samples from Iraq and glutamic acid is the lowest samples from Iran. It was obtained that while Loranthus europaeus samples grown in Iran is the richest in terms of total essential amino acids, on the other hand samples grown in Türkiye is the poorest. Total amino acids content was highest in Iraqi samples and the lowest in Turkish samples. It can be said that the variation of essential and non-essential amino acids contents between regions could be due to geographical, and ecological differences.</p></abstract>

Esansiyel olmayan aminoasitler bakımından, İran’da yetişen Loranthus europaeus, aspartik asit, serin, alanin, pirolin ve tirozin; Irak’ta yetişen, glutamik asit, asparajin, glisin, glutamin; Türkiye’de yetişen örneklerin ise sistein yönünden daha zengin olduğu bulunmuştur. Türkiye’de yetişen Loranthus europaeus örneklerinin asparajin, serin, glisin, glutamin, alanine, pirolin ve tirozin; Irakta yetişen aspartik asit, İran’da yetişen ise glutamik asit yönünden fakir oldukları söylenebilir.Toplam esansiyel amino asit açısından en zengin İran iken, en fakir Türkiye’de yetişen Loranthus europaeus örneklerinin olduğu belirlenmiştir. Toplam aminoasit miktarı en fazla Irak örneklerinde iken, en düşük olan ise Türkiye örneklerinde bulunmuştur. Esansiyel ve non-esansiyel aminoasit miktarlarının bölgeler arasında değişiklik göstermesi, coğrafi ve ekolojik farklılıklardan kaynaklandığı söylenebilir.</p></trans-abstract>
