[Selection of fungi--alkaloid producers--by the method of thin layer chromatography].

Microscopical fungi of the Penicillium genus were studied by thin-layer chromatography to select potential producers of alkaloids. A procedure for selection was developed to include microbial cultivation, extraction and conduct of qualitative and quantitative reactions on thin-layer chromatograms with routine alkaloid reagents. The cultures furnishing these reactions were selected for futher isolation and identification of products.
