【摘要】The pigments in Laminaria japonica was extracted with six organic solvents and analyzed in spectroscopy analysis.The extractions conditions were screened by an orthogonal test and the quantity of extracted pigments was determined spectroscopically.The results show that:(1) among the six organic solvents,acetone was the most effective one for the extraction; (2) the optimum extraction conditions were as follows:the ratio of S/M (solvent volume/ material weight) was 30ml/g; fresh seaweed was extracted 2 times in 2h; (3) the average total content of pigments was 1.85mg/g (calculated with dry L.japonica). 【总页数】4页(193-196)
