HYOSCYAMUS

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...

Quantitative Analysis of l-Hyoscyamine in Hyoscyamus reticulatus L. by GC-MS

The routine quality control of a herbal drug preparation requires the identification and determination of the contents of the active ingredients in the product. Measurement alone is not sufficient; it is also necessary to know how objectively to evaluate the experimental results . There are 6 Hyoscyamus (Solanaceae) species growing in Turkey, none of which are endemic. Hyoscyamus (Solanaceae) s...

The Chloroplast Genome of Hyoscyamus niger and a Phylogenetic Study of the Tribe Hyoscyameae (Solanaceae)

The tribe Hyoscyameae (Solanaceae) is restricted to Eurasia and includes the genera Archihyoscyamus, Anisodus, Atropa, Atropanthe, Hyoscyamus, Physochlaina, Przewalskia and Scopolia. Even though the monophyly of Hyoscyameae is strongly supported, the relationships of the taxa within the tribe remain unclear. Chloroplast markers have been widely used to elucidate plant relationships at low taxon...
