本研究的目的是通过测定两个红枣品种Ghars和Tamesritt的理化特性及其食用对血糖和血脂的影响，来评价两个品种红枣的品质。结果表明，两种枣的形态和理化特性从可接受到良好不等，具有较高的商业价值。植物化学研究表明，它们含有丰富的生物碱、多酚、单宁、黄酮类和香豆素，含量因品种而异。TAMESRIT和GHARS均含有丰富的酚类化合物，但TAMESRIT的总酚含量显著高于GHRS(p<；0.05)，TAMESRIT的抗氧化活性为900 mg，EAA/100g GHRS提取物为600 mg。生化成分分析表明，GHARS和TAMESRIT也含有丰富的纤维，水分含量在21%~26%之间，属于半软到软类型，还原糖含量在两个品种中都很重要，GHRS品种的葡萄糖含量较高，而TAMESRIT品种中不含蔗糖。红枣对血糖的影响表明，只有Tamesritt对血糖有显著的降低作用(p<；0.01)。关于血脂谱，我们注意到GHARS品种没有引起不同血脂参数的显著变化，而Tamesritt品种降低了LDLc水平(坏胆固醇)，从而改善了血脂谱。
The present study had the objective of evaluating the quality of two dates derived from two varieties of date palms, Ghars and Tamesrit, by the determination of physicochemical and biochemical characteristics and the effect of their consumption on blood glucose and lipid profile. The results obtained showed that both dates have morphological and physicochemical characteristics ranging from acceptable to good characters showing their commercial value. The phytochemical study showed their richness in Alkaloids, Polyphenols, Tannins, Flavonoids and Coumarins with different amounts depending on the variety. Tamesrit and Ghars have proved their richness in phenolic compounds, but the rate of total polyphenols was significantly higher (p <0.05) in the variety Tamesrit compared to Ghars with an antioxidant activity of 900 mg for Tamesrit and 600 mg expressed by EAA / 100 g Ghars extract. Biochemical composition revealed that Ghars and Tamesrit are also rich in fiber and have water content between 21 and 26 %, values classifying them in the semi-soft to soft category, the amount of reducing sugars is important in both cultivars, the glucose content is higher in the variety Ghars whereas sucrose is absent in Tamesrit. The effect of dates on blood glucose showed that only the variety Tamesrit had a significative decrease on blood glucose (p <0.01). Concerning lipid profile, we noted that Ghars variety induced no significant variation of different lipid parameters while the variety Tamesrit reduced the LDLc level (bad cholesterol), thus improving the lipid profile.
