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.

Total Flavonoid Content The determination of total flavonoids was performed according to the colorimetric assay of Kim et al. The antioxidant activity of phenolics is mainly due to their redox properties, which make them acting as alatta agents, hydrogen donors, and singlet oxygen quenchers. The overlaid UV-Vis spectra of the main peaks eluted later between minutes are depicted at the right corner.
AJPS high germination rate during storage. In vitro culture, micropropagation and the production of ephedrine and other alkaloids.
Effect of different storage co ntainers and storage periods month on the natural contamination of E.
Therefore, the role of seedborne fungi es. Maintenance of Ephedra alata Seeds Viability via. Results of a study of Ghasemi et al.
Such seedborne fungi differ in their coloniza tion in different parts of seeds with most of them are colon ized in seed. A Blotter and B agar plate techniques used for enumeration of seedborne fungi. Cotton cloth bags 5. Purified nitrogen was used as source and exhaust gases. Received October 22 nd; revised November 19 th; accepted November 22 nd The second technique however utilized sonication of the same weight of the herb stems using the same solvent volume for three hours.
Effect of various storage containers on shoot height cm of germinating seeds of E.
Ephedra alata Decne. — The Plant List
Seed samples g each were stored in four storage. The cupric ion reducing antioxidant capacity of the extracts was determined according to the method of Apak et al. After 30 min, the absorbance was recorded at nm against the reagent blank.
These types of compounds are very close to isomeric flavonoid glycosides. These medicines are used to treat circulatory disorders, kidney disorders, digestive system disorders and ephhedra disorders.
This shrub grows in dense clumps, on sandy calcareous, rocky and clay soils. Ephedraceae, is one of the oldest range and medicinal. 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.
Prolonged storage periods were accompanied with decrease in ephedrx index ranged between slight and significant reduction depending upon the nature of storage containers. Vanillic acid, Ferulic acid, Syringic acid, trans-cinnamic acid, Catechin, p-coumaric acid, Sinapic acid, 4-Hydroxyphenylacetic acid, Rutin hydrate, Caffeic acid, Quercetin, Gallic acid, 3,4-dihydroxyphenylacetic acid, chlorogenic acid, Taxifolin, Luteolin 7-glucoside, Apigenin 7-glucoside, Luteolin, Pehedra 3-D-galactose were from Sigma.
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. Effect of various storage containers on percentage germination of E. The HPLC system was then equilibrated for 5 minutes with the initial mobile phase composition prior injecting the next sample. Vigor index of E.

The other fungal genera. AJPS Figure 1. However, preparative HPLC collection of pure flavonoids from Ephedra plant along with NMR experiments would assist in the exact determination of their structure.
The four antioxidant activity assays were highly and significantly correlated with each other. For each experiment, the data were statistically analyzed. The genes Aspergillus was the most predominant and represented by 6 species namely A.
