[On the problem of henbane (Hyoscyamus niger L.) poisoning in children].

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...

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...
