28. Hyoscyamus in nercousness

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...

In this section we give various parameters for common detector components. The quoted numbers are usually based on typical devices, and should be regarded only as rough approximations for new designs. More detailed discussions of detectors and their underlying physics can be found in books by Ferbel [1], Grupen [2], Kleinknecht [3], Knoll [4], and Green [5]. In Table 28.1 are given typical reso...

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...
