Hyoscyamus albus تأثير بعض الهرمونات النباتية على تراكم قلويدات نبات السكران الأبيض لينيه

Abstract

White henbane Hyoscyamus albus L. One of the most important plants of the Solanaceae family is a plant rich in alkaloids Tropanic specially Atropine and Hyoscyamin of great medical importance. The effects of plant hormones IAA and AD were studied with different treatments (0, 10, 20 mg/L) for both root and stem. To determine the effect of these treatments on the build up of alkaloids, the amount of alkaloids in the plant was estimated, To study the biological activity of these substances on some bacterial strains. The results showed: the Hyoscyamus albus L. plant contains alkaloids as a major active ingredient in addition to the presence of glycosides, flavonoids, dragons, saponins and effects of cardinolides. Treatment with plant hormones gave significant accumulation in both root (2.24%, 2.23%) at 20 AD and 20 IAA, respectively, and leg (2.08%, 1.93%) at 20 IAA, 10 IAA respectively. The results of the biological test showed that the active plant material showed a clear effect on the three tested bacterial strains of Escherichia coli, Entérocoque sp, Klebseilla pneumoniae. The highest value of the mean diameter of inhibition was 16.12 mm on Entérocoque sp bacteria
