Advantages of DMF compared to the solvents ordinarily used are (1) higher extraction efficiency, (2) rapid extraction time of 30 min, (3) simple extraction procedure requiring neither extra heating nor grinding, but soaking, and (4) a long stable life of chlorophylla (at least one month at 5°C in the dark). the Oceanographical Society of Japan, 1989 Suzuki Reiko Ocean Research Institute, University of Tokyo, Nakano-ku, 164, Tokyo, Japan aut Ishimaru Takashi Tokyo University of Fisheries, Konan, Minato-ku, 108, Tokyo, Japan aut Journal of the Oceanographical Society of Japan Kluwer Academic Publishers 46/4(1990-08-01), 190-194 0029-8131 46:4<190 1990 46 10872 https://doi.org/10.1007/BF02125580 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/BF02125580 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Suzuki Reiko Ocean Research Institute, University of Tokyo, Nakano-ku, 164, Tokyo, Japan aut NATIONALLICENCE 700 1- Ishimaru Takashi Tokyo University of Fisheries, Konan, Minato-ku, 108, Tokyo, Japan aut NATIONALLICENCE 773 0- Journal of the Oceanographical Society of Japan Kluwer Academic Publishers 46/4(1990-08-01), 190-194 0029-8131 46:4<190 1990 46 10872 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
