Abstract
In the study, it was aimed to determine the constituents of laurel fixed oil obtained from the different genotypes of laurel (Laurus nobilis L.), which is one of the natural plants of the region and which is widely found in the flora of Hatay, by traditional, cold press and soxhlet extraction methods. When the GC/MS analysis results of these obtained oils were examined, the main components of the fixed oils in the traditional method were found as capric acid (2.49%), lauric acid (1.17%), myristic acid (0.16%), palmitic acid (13.69%), stearic acid (2.39%). ), oleic acid(55.01%), linoleic acid (10.56%) and linolenic acid(0.11%). In cold press method, fixed oil components wascapric acid (0.24%), lauric acid(9.24%), myristic acid(0.98%), palmitic acid (18.41%), stearic acid (2.84%), oleic acid (38.59%), linoleic acid (23.67%) and linolenic acid (2.19%), while it was determined as capric acid (0.46%), lauric acid (11.16%), myristic acid (1.54%), palmitic acid (18.39%), stearic acid (3.58%), oleic acid (36.92%), linoleic acid (23.02%) and linolenic acid (2.54%) in soxhlet extraction method. As a result, while the components of laurel fixed oil did not change according to the fixed oil extraction methods, the amounts of these components changed. Therefore, it was determined that the method of oil extraction in laurel was important.
Özet
Çalışmada Hatay florasında yoğun bir şekilde bulunan ve bölgenin doğal bitkilerinden biri olan defne (Laurus nobilis L.) genotiplerinden geleneksel, soğuk sıkım ve soxhlet ekstraksiyonu yöntemleri ile elde edilen defne sabit yağı bilileşenlerinin belirlenmesi amaçlanmıştır. Elde edilen bu yağların GC/MS analiz sonuçları incelendiğinde sabit yağların ana bileşenleri geleneksel yöntemde, kaprik asit (%2.49), laurik asit(%1.17), myristic asit(%0.16), palmitik asit(%13.69), stearik asit(%2.39), oleik asit(%55.01), linoleik asit (%10.56), linolenik asit(%0.11), soğuk preste, kaprik asit (%0.24), laurik asit(%9.24), myristic asit(%0.98), palmitik asit(%18.41), stearik asit(%2.84), oleik asit(%38.59), linoleik asit (%23.67) ve linolenik asit (%2.19) ve soxhlet ekstraksiyonunda kaprik asit (%0.46), laurik asit(%11.16), myristic asit(%1.54), palmitik asit(%18.39), stearik asit(%3.58), oleik asit(%36.92), linoleik asit (%23.02) ve linolenik asit (%2.54) olduğu tespit edilmiştir. Sonuç olarak defne sabit yağının bileşenleri sabit yağ çıkarama yöntemlerine göre değişmezken bu bileşenleri miktarları değişiklik göstermiştir. Bu yüzden defnede yağ çıkarma yönteminin önemli olduğu tespit edilmiştir.
