Phytochemistry And Pharmacology Of Plants From The Ginger Family, Zingiberaceae, Hans Wohlmuth
Phytochemistry And Pharmacology Of Plants From The Ginger Family, Zingiberaceae, Hans Wohlmuth
Dr Hans Wohlmuth
This thesis reports on a series of investigations into the phytochemistry and pharmacology of plants belonging to the ginger family, Zingiberaceae (incl. Costaceae). The work falls into two main parts. The first part examines the pungent compounds and essential oil in 17 clones of ginger (Zingiber officinale) with a view to identify one or more with unique chemistry and consequent particular therapeutic (or flavouring) prospects. The second part comprises the screening of 41 taxa for inhibition of PGE2 and other biological activities, with the primary aim of identifying species with potential anti-inflammatory activity. This part tested the hypothesis that the …

Dr Hans Wohlmuth
The hydro-distilled essential oils obtained from aerial parts of the wild (w) and cultivated (c) mint timija (Mentha suaveolens subsp. timija), an endemic medicinal species of Morocco, have been analyzed by GC–MS and screened for antimicrobial activity. In total, 35 compounds representing more than 98% of the oils were identified. Menthone (39.4(w)–10.8(c)%), pulegone (62.3(c)–34.3(w)%) and isomenthone (9.3(c)–7.8(w)%) were found as the main components for the two oils. The volatiles of the wild and cultivated material differed significantly in both the percentage of the main components and antimicrobial effect. Pulegone was more dominant in cultivated mint timija (62.3%) than in wild …
