ABSTRACT
Diabetes is a major health global problem that has
reached alarming levels. The present study aims for studying the effect of date
palm pollen (Phoenix dactylifera L.) El-Hayani cultivar on serum glucose
and lipids profile in induced diabetic male albino rats. Palm pollen chemically
analyzed besides chemical constituents, mineral contents, polyphenols and flavonoids. Male Albino rats (36 rats weight 170-190 gm) were divided into 6 groups. 1: Normal control (-), 2: Alloxanized diabetes control (+) (150 mg/Kg rat body weight). Diabetic groups 3 and 4 had
0.5%, 1.0% date palm pollen, respectively, also diabetic groups 5 and 6 had 100 ppm, 200 ppm date palm pollen
extract, respectively. At the end of the experiment (4 weeks) rats were fasted overnight and anesthetized
and blood samples were taken for analysis of serum glucose, lipids profile and renal-hepatic function parameters, relative
organ weight data obtained are statistically analysis. Results showed that the major polyphenolic components were that
e-vanillic acid (16.33 mg/100 g), pyrogallol (15.02 mg/100 g), epicatechin (11.04 mg/100 g), catechin (10.96 mg/100 g). While, date palm pollen was rich in hesperidin (8.84 mg/100 g), Kaempferol 3,2 p-coumaroyl glucose (6.92 mg/100 g), hesperitin (5.10 mg/100 g), rutin (3.11mg/100 g) as flavonoids components. Date palm pollen has high content of protein, calcium and iron (30.87 g/100 g, 510.82 and 236.50 mg/100 g), respectively. Also, serum glucose decreased
significantly in diabetic groups (3, 4, 5 and 6, respectively) (179.47, 137.80, 156.77, 145.47 mg/100 mL, respectively). Lipids profile, renal and liver
functions were improved significantly (P < 0.05) in diabetic groups which had date palm pollen or its extracts. It is concluded that the
dried date palm pollen 1% in the diet and 200 ppm extract are more effective
compared with controlling diabetes mellitus, also improve renal and liver
functions. Diabetics are advised to eat date palm pollen and are considered treatment foods for Diabetes
Mellitus.
