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.

These types of compounds are very close to isomeric flavonoid glycosides. The sequential incubation of seed sam.

Nutritional values total lipids, total nitrogen, ash content. 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. Quantitative estimation of aflatoxins were carried spectrophotometrically [24] using standard aflatoxins Sigma as reference. For each experiment, the data were statistically analyzed.

Each seed part aseptically used for investigation of seedborne fungi as described above.

The deterioration of plant community had occurred in Saudi Desert due to abiotic factors such as soil salinity [7], ed- aphic factors of the soil [29] and soil drought [6]. The results showed that Ephedra plant investigated in this study are richer with phenolic compounds The fungal colonies developing around the seeds incubated on both agar plates and filter papers were examined and the fungi were identified micro- scopically [15] and the level of incidence were recorded.

Vigor index of E. Evaluation of the Chemical Composition Rauwolfia serpentina and Ephedra vulgaris. These plants are perennial and xerophytic gymnosperm shrubs. Such seedborne fungi differ in their coloniza ephera in different parts of seeds with most of them are colon ized in seed. Statistical Analysis Three samples of Ephedra plant were independently analyzed and all of the determinations were carried out in triplicate.

Introduction Ephedra is a medicinal plant belonging to the Ephedraceae family. In Robert A. Please review our privacy policy.

Cotton cloth bags 5. From each seed sample, seeds were surface-disin. The usage of different storage containers for storing seeds indicated that the cotton cloth bags were the most favorable ones as they maintain seed moisture content SMC below the critical level resulting in minimum seed deterioration compared with other seed storage containers.

However, almost all the main peaks shared maximum wavelengths of The leaf arrangements are organized in an opposite pattern, with two leaves per node.


It can explain in terms of the decrement alteration in SMC inferior requisite level for growth and aflatoxins production by seedborne fungi [2;9]. It was noted as it is accom. These plants are also used for consumption by animals such as camelidae, bovines and caprines. Seedborne fungi use different mechanisms. Prolonged storage periods were accompanied with decrease in vigor index ranged between slight and significant reduction depending upon the nature of storage containers.

Root depth cm of germinating seeds of E. Additionally, correlations between the various antioxidant assays were performed.

Effect of various storage containers on shoot height cm of germinating seeds of E. Treatment means were compared.
