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...

cDNA encoding tropinone reductase-II from Hyoscyamus niger.

Two stereospecific NADPH-dependent reductases, TR-I and TR-11, constitute a branching point in the biosynthesis of tropane alkaloids. TR-I catalyzes the stereospecific reduction of tropinone to tropine (Koelen and Gross, 1982), whereas TR-I1 reduces tropinone to pseudotropine (Drager et al., 1988). We previously characterized TRs that had been purified from cultured roots of Hyoscyamus niger (H...

Three new resin glycosides and a new tetrahydropyran derivative from the seeds of Quamoclit pennata.

Three new resin glycosides, quamoclins V (1), VI (2), and VII (3) and a new tetrahydropyran derivative, quamopyran (4), were isolated from the seeds of Quamoclit pennata BOJER (Convolvulaceae). The chemical structures of these compounds were determined primarily on the basis of spectroscopic data. The carboxyl group of the aglycone, 11S-convolvulinolic acid, of 1 and 2 was linked intermolecular...

A new spirostanol glycoside from fruits of Solanum indicum L.

A new characteristic steroidal glycoside of the 23S,26R-hydroxylated spirostanol-type named indioside F was isolated from the fruit of Solanum indicum, along with indioside A and protodioscin. On the basis of spectroscopic analysis, the structure of indioside F was found to be 3-O-alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->4)]-beta-D-glucopyranosyl (beta-chacotriosyl) (22R,23...
