Hyphaene thebaica is distributed from Senegal and Gambia eastwards to Somalia, and is especially common between latitudes 8°N and 12°N. The Beneficial Dietary Hypotensive and Hypolipidaemic Effects of Hyphaene Thebaica (Doum). The Internet Journal of Alternative Medicine. Volume 7 . The doum palm (Hyphaene thebaica) is a type palm tree which has a wood texture and has edible oval fruits and the origin native to upper Egypt. The trunk of.

Chocolate, food product made from cocoa beans, consumed as candy and used to make beverages and to flavour…. Cholesterol-lowering effect of a theaflavin-enriched green tea extract: This chapter evidently reveals that the doum leaf and fruit extracts are effective antimicrobial and pharmacological agents.
The male inflorescence is a fodder in Sudan.
Doum palm fruit in its powder form was hyphane in some food products as a source of fiber, stabilizer and minerals as well as for its potential healthy effect [ 11 ]. Free radicals can react with biomolecules, causing extensive damage to DNA, protein, and lipid, which are considered to be related to aging, degenerative diseases of aging, cancer [ 4849 ].
Bundles of leaf strips to be thebaiica for weaving, as well as woven products are traded on local markets. Physiologically, antioxidants play a major role in preventing the formation of free radicals, which are responsible for many harmful oxidative processes [ 50 ]. The stem forms after 18—20 years.
Hyphaene thebaica – Useful Tropical Plants
Moreover, the ethyl acetate extract of doum fruit was active against five pathogenic bacteria, Staphylococcus aureusEscherichia coliBacellussubtilisPseudomonas aeruginosa and Klebsiella pneumonia while methanol extract was active against Pseudomonas aeruginosa and Klebsiella pneumonia. Total flavonoids content and compounds The total flavonoids content in different extracts of doum fruit extracts varied widely ranging from Branches of female spadices become thicker in the fruiting stage.
While it recorded the highest values in pitted doum fruit extracts varied from HPLC analysis of aqueous doum fruit extracts showed 11 flavonoid compounds Figure 4. Doum fruits showed antimicrobial and antihypertensive activities, and these activities were attributed to the presence of flavonoids [ 70 ].
Hyphaene thebaica has a wide distribution area and is often common, but it is locally overexploited and endangered. Figure 7 Table 4: Comments have to be approved before they are shown here. Male and female flowers are produced on separate trees.
The wood fibre cells are 0. Waste material from thwbaica extraction is used in Eritrea for stuffing and reinforcing cement. One of the most striking results of the present study is the improvement of the lipoprotein profile in response to Doum supplementation, with parallel reductions in the concentrations of both LDL and apo B, and thebaia in HDL and apo A-I, this effect of Doum must be considered as beneficial in the reduction of cardiovascular risk in these patients.
Polyphenolics and fat absorption. Therefore, both the inhibition of intestinal absorption of cholesterol and the accelerated clearance of plasma LDL may account for the observed hypolipidemic action of Doum.
Inhibition of in vitro human LDL oxidation by phenolic antioxidants from grapes and wines. For individuals aged 40—70 years, each increment of 20 mmHg in systolic blood pressure SBP or 10 mmHg in diastolic blood pressure DBP doubles the risk of cardiovascular disease Chobanian et al.
The palm can be coppiced and lopped. The first leaf is strip-shaped; fan-shaped leaves are produced from 2—3 years after germination onwards. Therefore, doum administration declines the oxidative damage and the renal interstitial fibrosis in rats [ 60 ].
The reaction is based on the relationship of an antioxidant toward iron II in relation to ferrozine, the assay is affected by both concentration of antioxidant and binding constant and thus only powerful iron antioxidant chelator is detected. As the plant H.
The large seeds germinate easily and readily, and should be planted in deep containers since tyebaica produce long ‘sinkers’ before any top growth is visible. The highest concentrations were quercetin, hesperetin, naringin and rutin compounds [ 18 ].
Methanol and aqueous extracts of doum fruit showed higherantibacterial activity against Gram-positive bacteria and Gram-positive bacteria except for Listeria monocytogeneswhere only a slight inhibition was hypharne [ 27 ]. Moreover, lowering the blood concentration of triglycerides helps to lower the amount of LDL. In Eritrea the petioles are woven into bed mats and used in the construction of houses, fences and bridges.
The highest germination for freshly-collected seeds was obtained with mechanically-scarified seeds soaked in water for 3 days. One of the few palm species that branches Photograph by: How to cite and reference Link to this chapter Copy to clipboard. In many studies, it has been reported that antioxidants show useful effects htebaica experimental colitis [ 55 ].
Doum Hyphaene thebaica is an African hyphaebe tree, common in Upper Egypt, originally native to the Nile valley, bearing an edible fruit which is glubose-quandrangularabout 6 x 5 cm with a shinny orange-brown to deep chestnut skin epicarp. This is due to the substantial amount of their thebiaca phenolic compounds [ 6 ].
