“…Our present study revealed a significant (p< 0.005) TEAC for AJ extract preparations, the results which run in parallel with that obtained by liu et al [6]. The antioxidant effects of AJ extract open several therapeutic utilities to the plant in senility, Parkinsonism, NSAIDinduced peptic ulcers and many other disorders induced by free radicals generation.…”

Artemisia judaica (AJ) is one of the common species of the genus Artemisia that grows in Saudi Arabia desert and Sinai, Egypt where animals graze on it. It is widely used in traditional medicine and by Bedouins there. (AJ) has anthelmintic, antibacterial, antiinflammatory, analgesic and antipyretic effects. The present study aimed to (1) elucidates the antibacterial action of AJ against H. pylori and different other bacterial species (2) delineate the potential antibacterial mechanism of action of AJ in comparison with tetracycline and cefotaxime (3) measure the trolox equivalent antioxidant capacity (TEAC) of the AJ water extract. Preparation of the (AJ) extracts was done by three different methods two of them are usually performed by population in Middle East by boiling of the shade-dried herb in water as tea (decoction), or soaked in tap water for over night (infusion), other method was done by concentrating the aqueous extract of Artemisia judaica under vacuum. The results of this study revealed that (AJ) has neither antibacterial effects either against H. pylori nor any other bacterial species. On the other hand the extract of AJ prepared by any of the above mentioned methods shows significant (p<0.005) antioxidant action as compared with blank and related to trolox antioxidant capacity.

“…The final DPPH was 0.1 mM. The mixture was shaken and incubated for 30 minutes at room temperature in the dark and then absorbance was measured at 517 nm using a UV-vis spectrophotometer (16). Methanol was used as a blank and ascorbic acid and butylated hydroxy toluene (BHT) (Sigma, USA) as positive controls.…”

RESUMO:A espécie Lippia gracilis SCHAUER (Verbenaceae) é nativa do Nordeste brasileiro e se destaca pela capacidade de acumular nos tricomas glandulares óleos essenciais com atividade antimicrobiana. Tendo em vista que não constam trabalhos na literatura sobre o estabelecimento in vitro dessa espécie, este trabalho teve como objetivo estabelecer protocolo para micropropagação de L. gracilis. Para tanto, ramos contendo folhas foram coletados de plantas matrizes no habitat natural para a confecção de estacas. Em laboratório, os explantes provenientes do processo de estaquia foram assepticamente tratados e inoculados em meio MS, acrescido de fitorreguladores, com o intuito de se estabelecer a melhor dose para o desenvolvimento dos explantes. Em decorrência de altos níveis de contaminação, avaliou-se o efeito da cefalexina. No entanto, apesar do antibiótico ter apresentado diminuição na contaminação bacteriana, a porcentagem de oxidação foi elevada. Portanto, testou-se o carvão ativado, ácido ascórbico, ácido cítrico e metade dos sais de MS quanto a eficiência no controle da oxidação. Concluiu-se que, o antibiótico na concentração utilizada provocou a oxidação dos explantes e os fitorreguladores, bem como os métodos antioxidantes testados, não apresentaram resultados consistentes para o melhor desenvolvimento dos explantes e controle da oxidação, respectivamente. Palavras-chave: Lippia gracilis, óleos essenciais, micropropagaçãoABSTRACT: Establishment of protocol for Lippia gracilis Schauer micropropagation. The species Lippia gracilis Schauer (Verbenaceae) is native to Northeastern Brazil and has been important for its ability to accumulate essential oils with antimicrobial activity in the glandular trichomes. Since there are no reports in the literature on the micropropagation of this species, the present work aimed to establish a protocol for L. gracilis micropropagation. Thus, branches containing leaves were collected from plant matrices in their natural habitat to prepare cuttings. In the laboratory, explants from cutting were aseptically treated and inoculated onto MS medium plus plant growth regulators in order to establish the best dose for the development of explants. Due to high levels of contamination, the effect of cephalexin was evaluated. Although the antibiotic decreased the bacterial contamination, the percentage of oxidation was high. Then, activated charcoal, ascorbic acid, citric acid and half the salts of MS were tested for their effectiveness to control oxidation. In conclusion, the used antibiotic concentration resulted in oxidation of explants. Furthermore, plant growth regulators and antioxidant methods did not show consistent results for a better development of explants and control of oxidation, respectively.
