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...

Cytomorphological studies on the colchiploids of Capsicum frutescens L.

Introduction The production of polyploids in crop plants by treatment with colchicine has been undertaken by a number of schools all over the world . The pre sent investigation deals with morphological and cytological comparison between the diploid and the colchicine-induced autotetraploids in Capsicum frutescens L. cultiver Oshkhosh, which is characterised by attractive yellow fruits when ripe...

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...

Effects of Silicon and AgNO3 Elicitors on Biochemical Traits and Antioxidant Enzymes Activity of Henbane (Hyoscyamus reticulatus L.) Hairy Roots

Lattice henbane (Hyoscyamus reticulatus L.) is an herbaceous, biennial plant belonging to Solanaceae family. H. reticulatus hairy roots were established from two-week-old leaves infected by A7 strain of Agrobacterium rhizogenes on solid Murashige and Skoog (MS) medium. In this study, abiotic elicitors including; Sodium silicate (Na2SiO3) with different concentrations (0, 1, 5 and 7 mM) and silv...
