    A comparative study of the phosphodiesterase 4 inhibitory activity of artemisia afra, Leonotis leonorus and mentha longifolia plant medicines
    (University of the Western Cape, 2007) Mulubwe, Ngosa.; Syce, James A.; Faculty of Science
    The specific objectives of this study were to investigate whether Artemisia Afra, Leonotis leonorous and Mentha Longiflora have PDE 4 inhibitory activity, to determine and compare the levels of the total phenolic compunds , total and individual flavanoids, especially luteolin and hesperetin, in the three plants and finally, to determine if there was a correlation between the PDE inhibitory activity and the levels of flavanoids or phenolic compounds in the plants. It was hypothesized that the plants with higher levels of total flavonoid and/or aglycone luteolin and/or hesperetin had higher PDE inhibitory activity.
