In this investigation, we aimed to study, for the first time, the phenolic composition of Pistacia lentiscus seed oils from different growing areas. Extraction of the phenolic fraction from oils was done by methanol/water. Phenolic profiles were determined using chromatographic analysis by High Performance Liquid Chromatography (HPLC-DAD/MSD) and its quantification was done using an internal standard which is unidentified in the studied oil (syringic acid). Forty phenolic compounds were quantified and only eighteen of them were identified. The eight studied oils showed different phenolic profiles. The total phenols amount varied from 538.03 mg/kg oil in Jbel Masour oils to 4260.57 mg/kg oil in oils from Kef Erraai. The highest amount of secoiridoids was reached by Bouchoucha oil containing 366.71 mg/kg oil of Oleuropein aglycon. Oils from Kef Erraai locality contained the highest concentrations in flavonols (377.44 mg/kg oil) and in phenolic acids (2762.67 mg/kg oil).

酚类成分及生长面积对黄连木种子油的影响

在这项调查中,我们旨在首次研究扁豆黄连木的酚类成分来自不同生长地区的种子油。用甲醇/水从油中提取酚类馏分。使用高效液相色谱(HPLC-DAD / MSD)进行色谱分析,确定酚类谱,并使用在所研究的油(丁二酸)中未鉴定的内标进行定量。定量了40种酚类化合物,仅鉴定出18种。所研究的八种油显示出不同的酚性。总酚含量从Jbel Masour油中的538.03 mg / kg油到Kef Erraai油中的4260.57 mg / kg油不等。含有366.71 mg / kg油橄榄苦苷糖苷配基的Bouchoucha油达到了最高的类脂环素含量。来自Kef Erraai地区的油中黄酮醇(377.44 mg / kg油)和酚酸(2762)的含量最高。
