Pteranthus dichotomus. Gypsophila arabica, Achillea fragrantissima, Urginea maritima, and Solanum elaeagnifolium exhibited strong cytotoxicity (above 97%) against cultured melanoma cell lines. Mesembryanthemum nodiflorum, Gypsophila arabica, Hammada scoparia. Trigonella foenum-graecum and Peganum harmala had more than 80% inhibition both in rootlet and melanoma assays. Hammada scoparia, Pulicaria crispa. Centaurea eryngioides, Echinops polyceras, Ephedra aphylla, Teucrium polium, Phlomis brachyodon, Urginea maritima, Ochradenus baccatus, Verbascum fruiticulosum, Corchorus olitorius, and Peganum harmala demonstrated strong growth inhibition (above 96%) of the malaria parasite Plasmodium falciparum.
