Optimized extraction of herbicidal active substance from Sasa argenteastriatus leaves
摘要
Abstract
The effects of different factors (extraction solvent,liquid ratio, extraction temperature, extraction times) on the herbicidal active ingredient extraction of S. argenteastriatus were studied through orthogonal experiment, and the inhibitory effects of extracts on weeds were appraised by the biological testing. The results indicated that the extraction percentage was highest, up to 14.50% in the condition of using 50% ethanol as extraction solvent with1:7 solid/liquid ratio, and extraction for three times at 60℃, when taken 75% ethanol as extraction solvent with 1:6 liquid ratio, and extraction three times at 80℃, the inhibition of the bamboo leaves extracts at a concentration of 0.4 g.L-1 to the root of Lactuca sativa L. and Agrostis stolonifera var. penncross were up to the highest levels, 67.83% and 36.82%, respectively.关键词
