PDF | The preliminary phytochemical analysis of Ephedra alata indicated the presence of cardiac glycosides, reducing sugars, flavonoids. Descriptions and articles about the Ephedra, scientifically known as Ephedra alata in the Encyclopedia of Life. Includes Overview; Distribution; Ecology; Hab. Two new flavonol glucosides have been identified in Ephedra alata, namely, herbacetin 8-methyl ether 3-O- glucosideO-rutinoside and herbacetin.

Department, Faculty of Science, King Saud University, Riyadh, Saudi Arabia for her excellent assistance in fun- gal identification that contributed in this success of this survey. Quantitative estimation of aflatoxins were carried spectrophotometrically  using standard aflatoxins Sigma as reference.
Such results were in agreed with our data recorded pre. There was a strong relationship between both storage. Such seedborne fungi differ in their coloniza tion in different parts of seeds with most of them are colon ized in seed coat, endosperm, and embryo of the seed. This can be attributed to the polarity of the extraction solvent and the flavonoids, where flavonoids need less polar solvent or higher amount of ethanol e.
Initial seed moisture content was 9. The cupric ion reducing antioxidant capacity of the extracts was determined according to the method of Apak et al.
Aspergillus and Fusarium were the most common genera. National Center for Biotechnology InformationU. Ephedraceae, is one of the oldest range and medicinal. In our results, afla- toxins production were found to be inferior with em- ployment of cloth bags followed by paper bags, tin cans and polyethylene bags respectively Tables 5 a,d. A Blotter and B agar plate techniques used for enumeration. Ephedra is a medicinal plant belonging to the Ephedraceae family.
In addition to alkaloids, Ephedra is a source of phenolic compounds and therefore possesses a high antioxidant capacity Eberhardt et al. As plant phenolics have multifunctional properties and can act as singlet oxygen quenchers and scavenge free radicals, the presence of substantial amounts of these compounds in Palestinian Ephedra promotes the latter as an important source of antioxidants which if properly consumed may reduce risk associated with degenerative diseases and provide health promoting advantage.
Ephedra alenda Stapf Andr. The leaf arrangements are organized in an opposite pattern, with two leaves per node.
Preparation and antioxidant properties of extracts of Japanese persimmon leaf tea kakinoha-cha J. Sawahreh4 and Imad Odeh 1. Their antioxidant activity is comparable ephedr higher to that of Epheda of other countries. Articles with ‘species’ microformats.
The mobile phase is a mixture of 0.
Nevertheless, similar mycological studies for many other seeds showed that Aspergillus and Fusarium were the most common genera as seedborne fungi [2; 16]. Aspergillus was followed by Fusa. It alatta explain in terms of the decrement alteration in SMC inferior requisite level for growth and aflatoxins production by seedborne fungi [2;9].
Standard curve was prepared using different concentrations of Trolox. The deterioration of plant community had occurred in Saudi Desert due to abiotic factors such as soil salinity , ed- aphic factors of the soil  and soil drought .
Ephedra alata – Wikipedia
Calibration curve of each individual standard was also prepared at three concentration levels namely 50, and ppm. Academic Press, London, pp. This page was last edited on 5 Septemberat Use of free radical method to evaluate antioxidant activity. The percentage inhibition of DPPH of the test sample and known solutions of Trolox were calculated by the following formula: Other major peaks appeared at retention of The reducing properties are associated with the presence of compounds which exert their action by breaking the free radical chain by donating a hydrogen atom.
The highest colonization of. The results of ferric chloride colorimetric test for determining flavonoids content are presented in Table 1. Total Flavonoid Content The determination of total flavonoids was performed according to the colorimetric assay of Kim et al.
In the same connection, the polyethylene as impermeable storage container followed by tin cans, paper bags and cloth bags, respectively caused significant alteration in concentration of both O 2 and CO 2which are the main cause of deterioration of agricultural products . The employment of cloth bags followed by paper bags, tin cans and polyethylene bags respectively diminished such as sharpness in the deterioration of seed biochemical aspects Tables 6 a-d.
Statistical Analysis Three samples of Ephedra plant were independently analyzed and all of the determinations were carried out in triplicate.

The stem of this plant contain alkaloid ephedrine which is a medicine used for the treatment of asthma and other respiratory ailments. It is found primarily in dry desert environments. Vigor index VI of E.
