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 30 ml/g; fresh seaweed was extracted 2 times in 2h; (3) the average total content of pigments was 1.85 mg/g (calculated with dry L. japonica).展开更多
