Chemataxonomic researches in higher plants. XV Carotenoid and chlorophyll pigments in the leaves of Cannabis sativa L.

[摘要] In the leaves of Cannabis sativa L. were found the following carotenoid pigments: ?-carotene, lutein, zeaxanthin, violaxanthin, neoxanthin and ?-cryptoxanthin. The ratio between the content of ?-carotene and lutein - which are the principal foliar carotenoids - was supraunitary, a feature that might be used as a chemotaxonomic criterion. It is worth to be mentioned the relatively high content of zeaxanthin and ?-cryptoxanthin in comparison with the level of these pigments in the leaves of most higher plants. The ratio between the content of chlorophyll a and b was of 2,17.
