Antimicrobial activity of the seeds of Hyoscyamus niger L. (Henbane) on microorganisms isolated from urinary tract infections

Objective: The methanol extracts obtained from the seeds of Hyoscyamus niger L. (Solanaceae) were investigated for their antimicrobial activities against the pathogens causing complicated urine tract infections. Methods: The seeds of plant were extracted with aqueous 60% methanol. The extract was screened against urinary tract pathogens (Enterococcus faecalis, Escherichia coli, Klebsiella pneum...

A soluble auxin-binding protein from Hyoscyamus muticus is a glutathione S-transferase.

We have used the photoaffinity label azido-[3H]IAA (5-N3-[7-3H]indole-3-acetic acid), a biologically active analog of indole-3-acetic acid, to identify auxin-binding proteins (ABPs) in the soluble fraction of Hyoscyamus muticus. A 25-kD polypeptide previously described (H. Macdonald, A. M. Jones, P. J. King [1991] J Biol Chem 266: 7393-7399) has now been purified to homogeneity by conventional ...

Assessment of Morphological and Tropane Alkaloids Diversity among some Henbane (Hyoscyamus niger L.) Populations

Background: Black henbane with the scientific name of Hyoscyamus niger which has a wide geographic distribution, is considered as one the most important species for tropane alkaloids extraction. Objective: In this research, morphological and tropane alkaloids variations were assessed within different population of H. niger in their natural habitats. Methods: Totally, 56 individuals were colle...

Changes of Tropane Alkaloids in Black Henbane (Hyoscyamus niger L.) in Response to Different Types of Nitrogenous Fertilizers

Background: Since alkaloids are nitrogenous compounds, the availability of nitrogen (N) is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants. Nitrogen has been found to increase the content of alkaloids in some of the medicinal plants. Objective: The aim of this study was to compare the effects of nitrogen bio-fertilizers, conventional nitrogen fe...
