In the species Retama retam retam, the presence of alkaloids observed in samples dried in the open air and in the oven.
From the results obtained in the species Retama retam retam, the highest content of polyphenols is recorded in the fresh extract (220.
Among the species Retama retam retam, the concentration of flavonoids is the highest recorded in the extract of oven 37.
Among the species Retama retam and Asphodelus tenuifolius oven dried, we see the greatest values of tannins compared to other drying methods that 7,09 [micro]g GAE / g DW and 0.
In the species Retama retam retam, there has been a growth inhibition of the bacteria Escherichia coli, they are Very small but there are remarkable circular zones around the disc in the studied extracts which are dried in the open air.
Biochemical analyses of that active substance by the test reducing sugars records their presence in both species Retama retam and Asphodelus tenuifolius to different modes of drying.
The assay of total phenols by Folin Ciocalteu, leads the dried plants in the oven have the best levels of polyphenols in Retama retam Rates (220.
Furthermore, the flavonoids assay solution of aluminum trichloride, we find that the oven-drying is the most conservative to the tenures of flavonoids in Retama retam costs (37.
The present research is a part of a specific study carrying out in Algeria to explore the allelopathic effects of five medicinal and aromatic plants Colocynthis vulgaris Schrad, Retama retam L, Traganum nudatum Del, Pituranthos chloranthus Benth.
For example, 3 and 5% of Colocynthis vulgaris Schrad root extract achieved the maximum inhibition percentage (95%) followed by 3 and 7% Retama retam (90%) and 3% Traganum nudatum Del (90%).
The allelopathic effect of 3,5 and 7% aqueous extract beside the control from shoots and roots of five donor species (Colocynthis vulgaris Schrad, Retama retam L, Traganum nudatum Del, Pituranthos chloranthus Benth.
