The amounts of neutral and polar lipids, chlorophylls, carotenoids and alkaloids have been determined in differentiated tissues of Codonopsis clematidea Schrenk grown by the tissue culture method. The qualitative and fatty-acid compositions of the neutral and polar lipids have been established and the presence has been shown of the quantitatively main alkaloid of the wild-growing plant, codonopsine, and of the minor alkaloid codonopsinine.
