title: Improved liquid chromatographic method for the analysis of photosynthetic pigments of higher plants.
abstract: The paper presents an improved reversed-phase LC method for the separation of the pigments from green leaves. A good separation of carotenoids and of their cis- and trans-isomers was achieved, especially for the separation of trans-lutein, zeaxanthin, cis-lutein, which are usually not well separated. No perfect separation of alpha-carotene, beta-carotene and pheophytin a was possible, but conditions for a perfect coelution of pheophytin a with either beta-carotene or alpha-carotene were established. Simultaneous equations allowing the determination of pheophytin a and alpha-carotene or pheophytin a and beta-carotene are also given.
