THE SIGNIFICANCE OF ACIDIC LICHEN SUBSTANCES IN THE ESTIMATION OF CHLOROPHYLL AND PHAEOPHYTIN IN LICHENS

Authors


SUMMARY

Acidic lichen substances are shown to be responsible for degrading extracted chlorophyll to phaeophytins in certain species of lichens and a method is proposed for eliminating this error during pigment extraction. The proposed extraction and measurement method is applied to lichens that have been maintained in either dry or deep frozen conditions.
