title: [Isolation and identification of protochlorophylls obtained by oxidation of corresponding chlorophylls].
abstract: Protochlorophyll with a high yield is isolated under oxidation of chlorophyll a by tetrachloro-o-quinone. A pigment, designated as protochlorophyll b, is isolated by the same way from chlorophyll b. A method of purification of the pigments obtained is worked out, their properties are studied and their structures are identified. The proposed method can be recommended for isolation of protochlorophyll a and b.
