[Chemical study of "Penicillium" and "Trichoderma" pigments (author's transl)]. / Etude chimique des pigments de Penicillium et de Trichoderma

The green pigments from the fungi of the genera Trichoderma and Penicillium were partially extracted with formic acid. After two acid and one alkaline hydrolysis, the pigments of Trichoderma viride and Trichoderma koningii were sufficiently purified to undertake the chemical studies. The elemental and functional analyses, the U. V. and visible spectra and the chromatographic observations showed that these pigments are polyphenolic in nature. Gel filtration on Sephadex G50 suggested, on the one hand, the homogeneity of the pigment of T. viride and, on the other, the heterogeneity of the pigment of T. koningii.
