These results demonstrated that the Epphedra plant extracts are rich with flavonoids range: Total phenols, antioxidant potential and antimicrobial activity of the methanolic extracts of Ephedra laristanica. Alkaloidal, lignan and phenolic constituents of Ephedra alata. Similarly, in our study both polyethylene bags and tin cans caused no any significant alteration in SMC compared with the initial SMChowever cloth and paper bags caused significant decrement in SMC Table 3.

The overlaid UV-Vis spectra of the main peaks are depicted at the right corner. Results and Discussions In the present investigation, 31 seed xlata of E. Aflatoxins B 1B 2and G 1 were extracted and cleaned up from storage seeds using chloroforme and cleaned usin g column chromatography according to AOAC [10]. The usage of different storage containers for storing seeds indicated that the.


Shoot height cm of germinating seeds of E. Nevertheless, similar mycological studies for many other seeds showed that Aspergillus and Fusarium were the most common genera as seedborne fungi [2; 16]. This wavelength was selected since the main Ephedra alata peaks showed a maximum absorption close to it.

These ephedga of compounds are very close to isomeric flavonoid glycosides. The mobile phase is a mixture of 0. Tropical Grasslands 4, The ovulate cones are oval, up to 10mm long, with pairs of overlapping yellow bracts surrounding two flowers.

Ephedra is known to have antibacterial and antioxidant effects. All chemicals and reagents were of analytical grade. Up to our knowledge, this is the first investigation for. Cases of isolation No. Ephedra is a medicinal plant belonging to the Ephedraceae family. Journal of EcologyVol. Production of plantlets from female gametophytes of Ephedra foliate Boiss. The highest colonization of storage aflatoxigenic molds such as A.

This page was last edited on 5 Septemberat It was noticed that extraction alaga sonication is much more efficient in comparison to typical infusion procedure Figure 1. The stem of this plant contain alkaloid ephedrineand other antimicrobial chemicals, which help protect this plant from disease. As antioxidants donate protons to this radical, the absorption decreases. These plants are perennial and xerophytic gymnosperm shrubs. The present study was designed to investigate the.


Ephedra alata Decne. — The Plant List

To enumerate seedborne fungi in different seed parts. The color changed from purple to yellow and the absorbance at wavelength nm decreased.

Seed samples of Ephedra alata Decne approximately. Eighteen phenolic and alatz standards mixture were injected and separated simultaneously to identify the presence of any of these compounds in the crude extracts.

The results showed that the Ephedra alata grown in Palestine is rich in antioxidants, phenolics and flavonoids. The effect of seed storage containers on aflatoxins pro.

A Blotter and B agar eohedra techniques used for enumeration. In the present investigation, 31 seed samples of E. Statistical Analysis For each experiment, the data were statistically analyzed using the analysis of variance procedure for completely randomized design.

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.
