“…Despite some investigations during the last decade (Al-Fatimi et al, 2007;Awadh et al, 2001;Mothana & Lindequist, 2005;Mothana et al, 2006Mothana et al, , 2007Mothana et al, , 2009), a minority of traditionally used medicinal plants have been evaluated for their pharmacological and chemical properties. Considering the importance of these untapped research areas, the aim of the present study was to evaluate the in vitro antimicrobial, antitumor, and antioxidant activities of 33 important medicinal plants, which are used in the Yemeni traditional medicine for various disorders including infectious diseases as well as different types of inflammations.…”

“…The quantitative estimation of the radical scavenging properties of the plant extracts was carried out according to the method of Al Fatimi et al [13]. The reaction mixture contained 500 mL of plant extract, 375 mL of ethanol and 125 mL of a solution of 1 Â 10 …”

A new electrochemical assay has been developed which is based on quantifying the attack of OH. radicals on a selfassembled thiol monolayer on electrodes in the presence and absence of antioxidants. The OH . radicals were produced in Fenton solutions. The radical scavengers diminish the concentration of the OH . radicals in the Fenton solution, and the extent of thiol layer destruction is monitored with the help of a redox probe in solution, the signal of which is only generated at SAM-free electrode surface. The results of the electrochemical assay were compared with those of the standard DPPH . assay. In case of each plant extract, an excellent linear correlation was observed between the radical scavenging activity and the concentration of plant extracts; however, the scavenging properties of different plants strongly differ in the electrochemical and the DPPH . assay. Since the proposed new method probes the reactivity of radical scavengers towards OH . , one of the most important reactive oxygen radicals in tissues, it is supposed to provide much more relevant information than the DPPH . or other assays.
