Should Seed Pods be Removed From Palm Trees

By Hossam S. El-Beltagi, Heba I. Mohamed, Hany N. Yousef and Eman M. 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 this small palm is dichotomous. It is one of the most important useful plants in the world. All parts of doum palm have a useful role such as fiber and leaflets which used to weave baskets and doum nuts which have antioxidants and secondary metabolites such as tannins, phenols, saponin, steroids, glycosides, flavonoid, terpenes and terpinoids.

Also, roots, stems and leaves are used in medicine, ropes and baskets. Studies on anti-inflammatory, antioxidant, antimicrobial, anticancer and pharmacological potential of Hyphaene thebaica extracts and its major phytoconstituents like the phenolic, essential oil and flavonoid compounds are extensively discussed in this review.

Antioxidants in Foods and Its Applications. Hyphaene thebaica is commonly referred to as doum, and it is a type of palm tree with edible oval fruit which belongs to the mint family Arecaceae.

They have several vernacular names like doum palm, doom palm, gingerbread palm, zembaba, mkoma, arkobkobai and kambash [ 1 , 2 ]. The doum palm is native to the northern half of Africa.

It tends to grow along the Nile River in Egypt and Sudan in the areas which contain groundwater. It grows in wadis and at oases, but it is considered as drought-tolerant and sometimes grows on rocky hillsides. Also, it is very resistant to destruction by fire in scrub or a forest [ 3 ].

This chapter focuses on the biological activities and beneficial effects of the Doum palm extract and its bioactive components in humans. The doum palm is a dioecious palm and grows up to 17 m 56 ft high. The trunk, which can have a girth of up to 90 cm 35 in , the trunk divided into two branches, each branch divided again into two branches, and the ends of the branches contain tufts of large leaves. The bark is smooth, dark gray and contains the scars of fallen leaves.

The petioles are about 1 m long, sheathing the branch at the base and contain curved claws. The leaves are fan-shaped and measure about by cm 47 by 71 in Figure 1. Male and female flowers are produced on separate trees. The inflorescences are similar in general appearance, up to about 1.

Male flowers have a short-stalk, solitary in pits of the spadix, spathe-bracts encircling the spadix, pointed. Branches of female spadices become thicker in the fruiting stage. Woody fruits are produced in the female palm that continues on the tree for a long time.

Its fresh weight is about g and dry weight is about 60 g and each one containing a single seed. The size of seeds about 2—3. Hyphaene thebaica L. Along the Nile, people used its fiber and leaflets to spin baskets. The fruits of doum palm are contained antioxidants [ 6 ]. Palms are used for firewood and charcoal. Leaves are probably the most important part of the palm, providing the raw material used in basketry, making mats, brooms, coarse textiles, ropes, thatching and string [ 7 ].

Leaves may also be used as fuel. The fibers of roots obtained after soaking in water for 2—3 days, and flogging of the roots are used for making fishing nets. Due to the high amounts of fibers in wood, it is difficult to cut them using an ax.

Wood produced from the male palm is considered better than that of the female. It is often used for building, providing for support and rafters for houses, railway sleepers, planks, water ducts and wheels fence posts and raft construction. Dried bark is used to produce a black dye for leather wear [ 8 ]. Roots are used in the treatment of bilharzia, while fruit pulp is helped in the reduction control hypertension [ 9 ].

The hard seed inside the fruit, known as vegetable ivory is used to treat sore eyes in livestock using charcoal from the seed kernel as well as making buttons and small carvings, and artificial pearls [ 1 ]. In Turkey and Kenya, the powder made from the outer covering of the fruit is added to water and milk and left to stand to make a mild alcoholic drink; in other countries, the terminal meristem is tapped for making palm wine. The thin dried brown rind is used in the manufacture of sweetmeats, cakes, and molasses.

In Egypt, the fruit is sold in herbalist shops and is popular among children. Apart from the use of the fruit as food, juice is extracted from the young fruit and palm wine is prepared from the sap [ 10 ]. Doum palm fruit in its powder form was applied in some food products as a source of fiber, stabilizer and minerals as well as for its potential healthy effect [ 11 ].

Research on the fruit pulp of H. Also, aqueous doum palm extracts increased the viability and activity of some certain dairy starter cultures which used in the manufacture of some dairy products especially probiotics [ 13 ].

Doum fruit has a high-quality protein varied between 2. Phytochemical compounds of doum fruit such as tannins, saponin, steroids, glycosides, flavonoid, terpenes and terpinoids were found at low and moderate concentrations [ 14 ]. Various extracts of H. The water extract of doum fruits can reduce hyperlipidemia in nephrotic syndrome and leads to decrease the risk of glomerulosclerosis and atherosclerosis and consequently the natural, safe and nontoxic H.

It is also good as hypocholesterolemic agent, hypolipidemic and hematinic suspensions lipidemic, and hematinic suspensions [ 17 ]. The identification of compounds by thin-layer chromatography showed that the doum fruit contains significant amounts of saponins, coumarins, hydroxyl cinnamates, essential oils and flavonoids [ 18 ].

It was found that the administration of flavonoid extracts to diabetic rats significantly increased adiponectin levels that stimulate the hypoglycemic action of insulin without altering the concentration of insulin in blood and decrease the weight and volume of contents of granuloma in inflammation [ 19 ].

Therefore, this might be its probable mechanism of anti-inflammatory action. Furthermore, the hypoglycemic effect of these herbs may be due to the increased level of serum insulin by increasing the pancreatic secretion of insulin from cells of islets of Langerhans or its release of bound insulin and also may be due to the enhancement of peripheral metabolism of glucose [ 20 ].

Repeated oral administration of doum fruits at 0. While the red blood corpuscles, packed cell volume, hemoglobin concentration and percent of phagocytic activity were significantly increased [ 21 ].

A significant decrease in blood glucose, cholesterol, triglycerides and total lipid levels was observed after 1 and 2 months of administration of the decoction of doum fruits [ 21 ].

The obtained results confirm the value of doum fruits as hematinic potentials, hypolipidemic, improve the hepato-renal functions and without side effects on the studied reproductive parameters. Also, triglycerides were independently related to coronary heart disease and most of the antihypercholesterolemic drugs did not decrease triglycerides levels, but the aqueous extracts of doum fruits lower it significantly [ 22 ].

This effect may be related to the increase in endothelium bound lipoprotein lipase which hydrolyzes the triglycerides into fatty acids. Previously, the authors reported that the hypolipidemic properties of the aqueous pulp suspension of doum could be partly due to the presence of glycosides [ 23 ]. Saponins have been reported to form complexes with cholesterol and bile in the intestine thereby indirectly reducing the cholesterol level in the blood [ 24 ].

Doum fruit yielded a yellowish color volatile oil with a fragrant aromatic odor at a yield of 0. Physical constants measured include: specific gravity 0. Monoterpenes representedOxygenated compounds constitutedFruit of doum oil was found to contain volatile diterpenes especially cembrene A which showed cytotoxic activity, and this revealed the medical importance of the volatile oil of doum which could be utilized medicinally [ 26 ]. Chemical structures of doum fruit essential oil.

Different total soluble phenols values in doum were published in different studies; it ranged fromWhile it recorded the highest values in pitted doum fruit extracts varied fromThe bioactive potential of fruits and vegetables attributed to their high content of polyphenols [ 28 ].

The most abundant phenolic compounds recorded in doum were metoxicinnamic acid, sinapic acids hydroxycinnamic acids , chlorogenic acid, catechin, p-hydroxybenzoic acid, vanillic acids, 3,4 di hydroxycinnamic acid, caffeic acid, 2-hydroxycinnamic acid, Epicatechinand cinnamic acid, respectively Figure 3 [ 29 ].

Doum pulps exhibited higher caffeic acid contents in comparison to the domestic fruits [ 30 ]. The highest four concentrations of phenolic compounds in doum fruit aqueous extracts were found to be 3-OH tyrosol, E-vanillic acid, catechin and chlorogenic acid, while the lowest were of alpha-coumaric acid, cinnamic acid, p-coumaric acid and coumarin [ 31 ].

Chemical structures of doum fruit phenolic compounds. The total flavonoids content in different extracts of doum fruit extracts varied widely ranging fromHPLC analysis of aqueous doum fruit extracts showed 11 flavonoid compounds Figure 4.

The highest concentrations were quercetin, hesperetin, naringin and rutin compounds [ 18 ]. Glycosides of luteolin and chryseriol flavones previously isolated from doum fruit were identified. In addition, isoquercetrin and isorhamnetin rutinoside are reported for the first time in H. Chemical structures of doum fruit flavonoid compounds. The aqueous ethanolic extract used to scavenge reactive oxygen species ROS. The phenolic content of doum was determined by using HPLC and recorded the presence of four major compounds correspond to Gallic acid, Quercetin glucoside, Kaempferol rhamnoglucoside, Dimethyoxy quercetin rhamnoglucoside, respectively.

All these compounds were isolated and identified for the first time in doum leaves [ 41 ]. Chemical structures of doum leave phenolic compound. Doum is one of the commonly consumed traditional beverages in Egypt and is rich in polyphenolic compounds. Several studies have recorded that doum fruit extracts contain high amount of flavonoids, phenols and used as antioxidant and antibacterial activities Table 1 , which can alleviate the adverse effects of oxidative stress and prevent diseases caused by pathogenic bacteria [ 16 ].

It is well-known that plant phenolic compounds are highly effective free radical scavengers Figure 6. Phenolic compounds antioxidant activity is associated with the presence of functional groups in the ring and the annular structure of the molecule, conjugated double bonds [ 42 ]. The antioxidant activity increased with the increase in concentration and the consumption of doum plant which would exert several beneficial effects by the value of its antioxidant and antimicrobial activities [ 27 ].

But I guess I should expand a little bit given there is so little information on the subject. Well, I agree, there is no point, the bigger they get the more beautiful they are… usually. The above picture shows our Cordyline on 29th January , five years after I moved it to this spot and the fateful day I decided to bite the bullet and lop it down. There were three problems with our Cordyline due to the fact our patio is West facing. Firstly, it is leaning more and more toward the sun to the south, this lean was pulling the roots out of the ground.

Branches of female spadices become thicker in the fruiting stage. Woody fruits are produced in the female palm that continues on the tree for a long time.

Date palm trees are grown for its fruit and are the oldest cultivated tree fruits. The fruits known as dates are sweet and highly nutritious fruits. The major producers of date palm trees are countries in the Middle East and other countries in Africa while Iran is the largest exporter. Date palm trees are cultivated in dry arid zones having irrigation facilities. Date farming can have a successful cultivation in regions that have prolonged hot dry summer, moderate winter climatic conditions with no rain during the fruit ripening period. Date trees grow about 65 to 70 feet 20 to 21 m in height. The trunk is cylindrical and columnar growing straight with the same girth to the top. Date palm is a dioecious tree which means the male staminate and female pistillate flowers are born on two different palm trees. The fruits are one to four centimeters long with 2.
