The absorption spectrums of ethanol extracts from green leafs

In this article the objective laws the correlation of content a chlorophylls and other pigments in green leafs are described. It is recording absorption spectrums of extracts from leaves 34 plants 21 families. This spectrum subdivides into three basic types by arrangement of greatest maximum in middle-wave, long-wave ultra-violet, visible part of optical range. We estimate the relative content of chlorophyll and other pigment by ratio optical density of length wave 664 nm and optical density of length wave of greatest maximum. The fi rst type is characterized by low, the second type by middle and third type by the most content of chlorophyll in green leaves in comparison with other pigments
