New spectrophotometric equations for determining chlorophylls a, b, c1 and c2 in higher plants, algae and natural phytoplankton

Summary New equations are presented for spectrophotometric determination of chlorophylls, based on revised extinction coefficients of chlorophylls a, b, c1 and c2. These equations may be used for determining chlorophylls a and b in higher plants and green algae, chlorophylls a and c1 + c2 in brown algae, diatoms and chrysomonads, chlorophylls a and c2 in dinoflagellates and cryptomonads, and chlorophylls a, b, and c1 + c2 in natural phytoplankton.
