Secondary Metabolites (Pterosin F and B) From Pteridium aquilinum

Monica Butnariu¹

Abstract: Secondary metabolites with active potential of fern are phenolic compounds, ptaquiloside (C 20 H 30 O 8 ), pterosins (group of sesquiterpenes and norsesquiterpenes), hydrogen cyanide, and also produces carcinogenic compounds, etc. contains flavonoids, which have antibiotic properties, compounds that may have potential against fungal agents, pests for organic production.

Abstract. During the period 2011-2013 a monitoring of entomofauna was performed in environmentally justified crop rotation including alternation of legumes (field beans, forage peas) with cereals (wheat, malting barley). Conventional entomological methods were used for identification of species and population density of harmful insects and their entomophaga. The results were processed according to the crops. In no one of the four crops, pests in density over Economic Injury Level were detected. Diversity of entomophaga was explained via the favorable ecological environmental conditions and namely by the presence of the trophic factor and the absence of chemical treatments with insecticides.

Abstract. Artemisinin, a sesquiterpene lactone; is one of the most well-known secondary metabolites with multi-functional therapeutic effects which is isolated from Artemisia annua. Due to low levels of artemisinin in this plant, efforts are being made to optimize its production by various strategies such as elicitation-infiltration. This is a procedure in which, elicitors are injected to the plants by fine-needles directly. In this study, we identified the effect of bacterial and fungal elicitors on artemisinin level and biomass accumulation in A. annua. Artemisinin content was measured by high performance thin layer chromatography. The maximum level of artemisinin was accomplished by injection of 0.4 mg total sugar/ml F. oxysporum and B. cereus decreased artemisinin content in comparison to the controls. 1 McFarland S. aureus was the most successful elicitor, increasing the fresh weight 1.34 fold over the controls.
