Phenolic compounds of the plantGossypium hirsutum and of callus tissue from its anthers

The chemical composition of the catechins, leucoanthocyans, proanthocyanidins, and anthocyans of callus tissue ofGossypium hirsutum L. has been studied in comparison with cotton plants growing under natural conditions. From callus tissue of lines L-29, L-32, and L-35 we have isolated (+)-catechin, (±)-gallocatechin, (−)-epicatechin, cyanidin 3-O-β-D-glucopyranoside, and cyanidin 3-O-[O-β-D-xylopyranosyl-(1→4)-β-D-glucopyranoside]. It has been shown that the components of the phenolic complexes in the plant and in callus tissue differ qualitatively and quantitatively.
