Multistage solvent extraction influence on Artemisia Dubia WALL. biomass characteristics

ONLINE ISSN: 2335-8718In recent years, there has been increasing interest in the use of agricultural biomass for energy purpose in many northern countries. This has created demand for novel, high biomass yielding, specific quality crops for sustainable use.[1] Artemsia dubia Wall., also known as mugworth, is a grass plant, with a very high growth yield and is currently being considered as one of the more popular biofuel alternatives. The purpose of the research is to maximize the use of this plant by adding an additional biotechnological step to the equation - extraction. Using Thermal equipment research and testing laboratory standards and equipment, thermal capabilities, moisture and ash content was determined. As for the extracts gotten from solvent-solvent extraction, it was seen that small concentrations of both polar and nonpolar fractions are required to trigger noticeable allopathic activates on Lepidium sativum seeds germination and growth. Also the phenolic contents of these fractions were determined, noticing low doses of phenols in non-polar solvents to those of polar ones. Finally, thermal capabilities, together with organogenic and ash content decreased significantly after solvent extractionBiochemijos katedraGamtos mokslų fakultetasLietuvos energetikos institutasVytauto Didžiojo universiteta
