In this research, supercritical CO2 extraction is applied to extract bioactive compounds from Lamium album (white dead nettle, Lamiaceae). Extraction was performed at various temperatures (40, 50, and 60 °C) using methanol as co-solvent a constant flow rate of CO2, methanol, pressure. The collected extracts were characterized in terms antioxidant capacity by DPPH, ABTS FRAP vitro activity assay...

Experiments were conducted to evaluate the effect of tillage systems and weed management on weed suppression and potato yield. Striptillage (ST) and conventional-tillage (CT) systems produced equal yields of Irish potato (Solanum tuberosum L.) or sweetpotato [Ipomoea batatas (L.) Lam.] when herbicide treatments were applied. Weeds in the nontreated control reduced yield of Irish potato and prev...

Alfalfa is one of the most important perennial fodder crops, and it also economical. provides first class that suitable for feeding all livestock, especially ruminants. Grass broadleaf weeds are a serious threat to quality viability alfalfa stands. Weeds can reduce nutritional value crop cause significant reductions in yield, as they compete aggressively water, nutrients, sunlight, space. In th...

Geographic variation of flower size is potentially affected by various biotic and abiotic factors such as pollinator size, abundance of nectar robbers, and temperature. To elucidate the effect of geographic variation of flower-visitor fauna on flower size, we investigated two spring-flowering, bumblebee-pollinated herbs, Lamium album L. var. barbatum (seven populations) and Meehania urticifolia...

Uno de los principales problemas productivos del alcaucil son las malezas, siendo necesario disponer herbicidas que efectúen un adecuado control. Se evaluó la eficacia en el control malezas etapas iniciales cultivo, y fitotoxicidad sobre mismo. El experimento se realizó FCA, UNR, Madrigal, sembrado octubre trasplantado noviembre 2014. aplicaron preemergencia malezas: S-metolacloro, Oxifluorfen,...

The antimicrobial activity of 18 different extracts from in vivo and in vitro grown L. album L. plants was evaluated against clinical bacteria and yeasts using the well diffusion method. All the used extracts demonstrated antibacterial activity, whereas only the water extracts from leaves (in vivo) possessed antifungal activity against Candida albicans NBIMCC 72 and Candida glabrata NBIMCC 8673...

The anatomy, morphology and trichome distribution on the aerial parts of Lamium truncatum Boiss. were studied in order to understand the usefulness of these characteristics for systematic purposes. L. truncatum is a Mediterranean element which grows on shady hedge banks, glades, Quercus coccifera L. macchie and forest at an altitude of 300-1650 m in the eastern part of the Mediterranean region ...
