The Phytoconstituents Screening and Antibacterial Activities of Leaves, Seeds Bark and Essential Oil Extracted from Carya illinoinensis Plant

Abstract

Pecans (Carya illinoensis) considered as ‘Queen of Nuts’ because of its value both as wild and as cultivated nut. Merely may there are no adequate studies related to the composition of the shell and to the presence of compounds with possible positive effects. Thus, the objective of the present work was to determine the nutritional composition. The yield of extract was calculated for the two parts extracts of Carya illinoensis and studied for qualitative and quantitatively analysis of phytochemical constituents. The plant extracts were positive for a wide range of bioactive compounds such as Tannins, Saponins, Flavonoids, Steroids, Terpenoids, Phenols, Carbohydrates, Amino Acids, Alkaloids and Glycosides, and further were studied the evaluations quantities for each of Alkaloids, Saponins and flavonoids contents, where the total Alkaloids in the leaves was 49% and for seeds bark was 75%, while the Saponins was 55% , 62% respectively and Flavonoids was 45% for leaves, 71% for seeds bark. In addition, An antibacterial activity was carried out for the crude extracts against four pathogenic bacteria, whereas The results obtained indicated a high antibacterial activity determined through different methodology. As well, the extraction of oil from the fresh seed of Carya illinoensis seed by using appropriate solvents (hexane and ethanol, separately) has been successfully taken place by Soxhlet Extractor and then the properties of the extracted oil were studied by physiochemical determination. Where the absolute yield of extracted seeds oil was 35%. While the values of the physiochemical properties of the oil were 182 for Saponification, 8.3 for acid value, 7 for peroxide and 1.4776 was for the refractive index. Therefore, the results of extracted oil from the seeds of Carya illinoensis in this study have showed that this oil could be utilized successfully as source of edible oil for human consumption.
