Momilactones A (M A ) and B (M B ) are phytoalexins derived from rice plant (Oryza sativa) and were considered to be a part of the mechanism of rice self-defense system. The present study was to evaluate the comparative efficacies in vitro of antibacterial, fungicidal, antioxidant, and herbicidal activities of M A and M B . In general, M B shows higher antifungal, antibacterial, and herbicidal action than M A , although its antioxidant property was less than M A . In herbicidal trial, the IC 50 values of M B against germination, shoot and root elongation of barnyardgrass and monochoria were 40.9, 45.5, and 27.5, and 27.1, 17.3, and 0.9 mg, respectively. For M A , these values were 40.3, 35.6, and 55.1, and 43.9, 24.3, and 0.5 mg, respectively. For antifungal activity, momilactone B (IC 50 : 1.2, 123.9, and 53.4 mg) exerted significantly greater inhibition than M A (IC 50 : 78.1, 198.1, and 95.3 mg) against Botrytis cinerea, Fusarium solani, Colletrotrichum gloeosporioides, respectively, except for Fusarium oxysporum that both M A and M B showed no marked difference. In addition, M B exhibited significantly stronger antibacterial activity than M A against Pseudomonus ovalis, Bacillus cereus, and Bacillus pumilus, whereas the inhibitory activity of the two compounds was similar against Escherichia coli. Both M A and M B exerted rather weak antioxidant activity (EC 50 was 783.9 and 790.7 mg, respectively), of which M A showed a slightly stronger antioxidant activity than M B . This study is the first to examine antifungal, antibacterial, and antioxidant activities of two phytoalexins, as well as their comparative efficacies against growth of the noxious weeds barnyardgrass and monochoria.

“…These results demonstrate the importance of this plant family in the control of other snail species. The species Bidens pilosa Linné (Asteraceae) popularly known as hairy beggarticks, is a herbaceous plant with a short annual cycle (Lorenzi 2000) widely distributed in Brazilian territory, being used in folk medicine (Adegas et al 2003) for antimicrobial (Rojas et al 2006, Deba et al 2008), hepatoprotective (yuan et al 2008, diabetes (Chien et al 2009) andulcer (Freise 1933) antitumoral (Kumari 2009, Kviecinski et al 2008 and antioxidant (Krishnaiah et al 2011).…”

The aim of this study was to establish reference concentrations (LC 50 e LC 90 ) of aqueous extracts of Bidens pilosa on the land snail Subulina octona, in order to assess the changes caused by 24 and 48 h exposure to the sublethal concentration regarding species' fecundity, hatchability and in offspring produced after exposure to confirm the presence of tannins, saponins and flavonoids in this plant species. Eggs newly hatched and 30 day-old snails were exposed to sublethal concentration, calculated for adults. The phytochemical analysis confirmed the presence of flavonoids, condensed tannins and saponins in the aqueous extract of B. pilosa. The LC 50 and LC 90 obtained were 51.4mg/mL and 74.1mg/mL respectively. The exposure to sublethal concentration reduced significantly the hatchability and the survival of the offspring hatched from exposed eggs and also caused a reduction on survival and growth in snails exposed for both time period. The exposure time also caused a reduction at the evaluated parameters.

“…There is evidence that there are some synergic and antagonistic interactions between phenolic compounds. These interactions can modify their antimicrobial effect (Deba et al, 2008), which can ex-plain why the complete extracts of Ephedra breana y Nolana sedifolia did not showed any control effect, even though the ethanolic fractions of those plants can inhibit the mycelial growth. It is also interesting the presence of 3, 4-dimethoxycinnamic acid in the two fractions that show control of mycelial growth, and of 3, 4-dimethoxybenzoic acid in the ethanolic fraction of E. breana.…”

Abstract:The antifungal effect of the complete methanolic extract and a ethanolic fraction of three native Chilean plants (Ephedra breana, Fabiana imbricata, and Nolana sedifolia) were tested in vitro against Botrytis cinerea (the grey mold fungus) at 250 µg/mL for E. breana and N. sedifolia extracts and 400 µg/mL for F. imbricata extract. The results of this study showed that the ethanolic fractions of E. breana and N. sedifolia have a fungistatic effect during 14 days, while the fungus is exposed to the media with extracts. The complete methanolic fractions of the three studied plant species and the ethanolic fraction of F. imbricada did not show any fungicidal effect. The extracts and fractions were analyzed by high-performance liquid chromatography and the assayed compounds were: chlorogenic acid, cinnamic acid, p-coumaric acid, ferulic acid, vanillin, vanillic acid, rutin, caffeic acid, 3, 4-hydroxibenzoic acid (veratric acid), 3, 4-dimethoxycinnamic acid (caffeic acid dimethyl ester), and protocatechuic acid. Taking into account the antifungal activity of the ethanolic extracts of E. breana and N. sedifolia in in vitro assay, they may be an interesting alternative to control the phytopathogen Botrytis cinerea. Key words: Ephedra breana, Fabiana imbricata, fungicidal, Nolana sedifolia phenolic compounds, plant extracts.Resumen: Se estudiaron los posibles efectos antifúngico de los extractos metanólicos crudos y fracciones etanólicas de tres plantas nativas de Chile: Ephedra breana, Fabiana imbricata y Nolana sedifolia sobre el desarrollo micelial in vitro del hongo fitopatóge-no Botritis cinerea (moho gris), a una concentración de 250 µg/mL de E. breana y N. sedifolia, y de 400 µg/mL para F. imbricata. Los resultados ponen en evidencia que las fracciones etanólicas de E. breana y N. sedifolia ejercieron un efecto inhibitorio del crecimiento micelial de B. cinerea, en condiciones in vitro. Este efecto demostró ser fungistático y se mantuvo durante los 14 días evaluados. Los extractos completos de ambas especies no mostraron efectos inhibitorios. Los extractos completos y las fracciones etanólicas fueron analizadas por cromatografía líquida de alta eficiencia y entre los compuestos encontrados fueron: ácido clorogé-nico, ácido cinámico, ácido p-cumárico, ácido ferúlico, vainillina, ácido vainíllico, rutina, ácido caféico, ácido 3,4-hidroxibenzoico (ácido verátrico), ácido caféico dimetil ester (ácido 3, 4 dimetoxicinámico) y ácido protocatéquico. Las fracciones etanólicas obtenidas pueden considerarse como una promisoria alternativa para el control de este fitopatógeno.
