Qualitative Analysis of Active Materials in Date Samples and Determination of their Essential Components

الملخص

The present study concentrated on samples of Libyan dates procured from the markets in Gharyan City. A series of qualitative analyses were conducted in order to assess the content of their active ingredient, with a particular focus on antioxidants. The qualitative identification of tannins, flavonoids, glycosides, saponins, and resins (utilised as tanning agents) was conducted utilising standard reagents such as Dragendorff's, Fehling's, and Benedict's, in conjunction with date extracts. The analyses confirmed the presence of all these compounds in the samples. Furthermore, quantitative assessments of the fundamental components of the date samples were conducted. The procedure entailed the quantification of fibre, carbohydrates, protein, fat, and ash content. Furthermore, the moisture content and the ratio of pits to fruit were evaluated in all samples. The assessment employed a kiln, a Kjeldahl apparatus, and other requisite equipment to determine the caloric values of each sample. The findings indicated variations in the fundamental components and energy content among the samples, likely attributable to various factors and conditions.
