| Abstract: | Metabolites ofAlternaria alternata were produced on rice as a solid substrate, chosen out of 6 substrates as the most useful. Optimal methods of extraction, purification, and separation of 5 metabolites were elaborated, using liquid — liquid partition, column chromatography, and preparative TLC. Alternariol, alternariol methyl ether, and copper salt of tenuazonic acid were obtained as crystals, altertoxin and altenuene as a film. |
