Two varieties of dates (Amey and Tagiat) were used in this study.

Samples were collected from the Souq al jumaa market in Tripoli, Libya.

The dates fruit were divided into two parts after cap was removed, The seeds and skin (cortex).

A preliminary analysis of seeds and skin were carried out for both cultivars contents of moisture, fat, protein and ash.

A chemical analysis tested the presence of alkaloids, flavonoids, tannins, coumarins, anthraquinone glycoside and cardiac glycoside.

Results showed that the moisture content in seeds was higher than that in the skin of both date varieties.

The results also showed that the fat content in seeds of Tagiat dates was higher than that found in the seeds of Amey dates.

The study found that seeds contain a higher percentage of fat than skin.

Protein content in seeds was higher than that in skin.

The study showed that seeds of Amey dates contained the highest ash content, followed by Tagiat dates’ seeds, then the skin of the Amey dates, and, finally, the lowest percentage of ash was recorded in Tagiat dates’ skin.

Phytochemical analysis revealed the presence of flavonoids, coumarins, anthraquinone glycosides and cardiac glycosides in both varieties under study.

No tannins were detected in the skin while they were presented in the seeds in both cultivars.

The most important recommendations of this study are that dates seeds and epicarps are suitable for animal feed due to their high contents of fat and protein, and that the presence of active compounds such as flavonoids, coumarinms, glycosides anthraquinone, and cardiac glycosides in the skin of dates makes them highly suited for use in therapeutic formulations.

Given the high content of proteins and fats in the seed, it could be employed as natural additive in food and nonfood formulations.
