“…Silphium perfoliatum L. is a perennial, tall, yellow flowering C 3 plant, characterized by a wide range of valuable practical traits and has been cultivated as a medical, melliferous, fodder, ornamental, and reclamation plant (Niqueux, 1981;Neumerkel and Märtin, 1982;Troxler and Daccord, 1982;Daniel and Rompf, 1994;Kowalski and Wolski, 2005;Kowalski and Kędzia, 2007;Zhang et al, 2010). In recent years, S. perfoliatum L. has been of interest as an energy crop, especially for biogas production (Vetter et al, 2010;Bauböck et al, 2014;Mast et al, 2014;Gansberger et al, 2015).…”

SummarySilphium perfoliatum L. is a perennial and flowering crop that has been investigated in recent years for its potential as an energy plant, particularly for biogas production. A stand establishment by sowing of seeds is complicated, owing to the low germination capacity of untreated S. perfoliatum L. seeds. Consequently, germination experiments were carried out with two-to four-factor levels to determine the effect of selected factors (medium, pretreatment, light, temperature, prechilling) on dormancy and germination of S. perfoliatum L. seeds and to achieve maximum germination rate. All factors had a highly significant effect on germination. Germination experiments displayed a primary and physiological dormancy. Germination could be significantly increased by using a 0.05% GA 3 solution during the imbibition phase, a light-dark cycle, alternating temperatures between 20°C and 30°C, and a wet stratification for seven days at 0°C. The experiments helped to fully exploit the germination potential and to develop a germination test method for S. perfoliatum L.Keywords: bioenergy, cup plant, dormancy, seed production, seed treatment ZusammenfassungSilphium perfoliatum L. ist eine ausdauernde und blühende Pflanze, die in den letzten Jahren hinsichtlich ihres Potentials als Energiepflanze für die Biogasproduktion untersucht wurde. Eine gesicherte Bestandesbegründung mittels Saat ist aufgrund der geringen Keimfähigkeit von unbehandelten S. perfoliatum L.-Samen schwierig. Folglich wurden Keimversuche mit zwei bis vier Faktorstufen durchgeführt, um die Wirkung ausgewählter Faktoren (Medium, Vorbehandlung, Licht, Temperatur, Vorkühlung) auf die Dormanz und die Keimung von S. perfoliatum L.-Samen zu bestimmen und die maximale Keimfähigkeit zu erreichen. Alle untersuchten Faktoren hatten einen signifikanten Effekt auf die Keimung. Die Keimfähigkeitsversuche ergaben eine primäre und physiologische Dormanz. Die Keimfähigkeit wurde durch den Einsatz einer 0,05% GA 3 -Lösung während der Quellungsphase, eines Licht-und Dunkelwechsels, einer alternierenden Temperatur zwischen 20 und 30°C und einer nassen Stratifikation von sieben Tagen bei 0°C signifikant erhöht. Damit wurde das Keimfähigkeitspotential ausgeschöpft und eine Keimfähigkeitsprüfmethode für S. perfoliatum L. entwickelt.

“…The min imu m bactericidal activity (MBC) of the extract for different bacteria ranged between 0.312 to 1.25 mg/ ml, Methanol and Hexane extracts were more active than other extracts. This may be attributed to the presence of soluble phenolic and polyphenolic compounds [16] . The inhibitory effect of the ext ract of Elytraria Acaulis against pathogenic bacterial strains can introduce the plant as a potential candidate for drug development for the treatment of ailments caused by these pathogens.…”

Antimicrobial activ ity of the aerial parts of the Elytraria acaulis a stem less perennial herb of Acantheceae family has been carried out in the present study. Extracts of the aerial parts of the plant (Stem & Leaves) were prepared in different organic solvents such as n-Hexane, Ethanol, Methanol and Ethyl acetate. All the extracts were analyzed for antimicrobial properties against various pathogenic bacterial infect ions (Escherichia coli, Klebsiella Species, and Salmonella Typhi). Amongst all the extracts, methanolic extract exh ibited significant antimicrobial activ ity. The crude methanol extracts of leaves showed good inhibitory effects against pathogens. Hence further studies on this plant will enable elucidation of its therapeutic properties and medicinal applications.

Several compounds present in fruits as Polyphenol, are able to kill or inhibit the growth of microorganisms. These properties are relevant mainly in tropical areas, as Amazonian region where infectious are highly prevalent. Therefore, this study investigated the antimicrobial activity of Jatropha curcas seed cake against microorganisms. The results showed antibacterial effect of Jatropha curcas seed cake methanolic extracts on two Gram-positive bacteria and Gram-negative bacteria. Effect of Jatropha curcas seed cake on Superoxide and nitric oxide production was also estimated in macrophage cells. This result suggests its anti-inflammatory and antibacterial potential of the herb, which could be due to the bio-active principles which are anti-inflammatory and antibacterial in nature. The present study, therefore emphasizes the use of Jatropha curcas seeds as an anti-inflammatory and antibacterial drug against macrophage cells and bacteria respectively.
