  Four new metabolites, italicic acid, dihydro-italicic acid, methyl italicate and italicinic acid, were isolated from culture medium of Penicillium italicum WEHMER. The structures, possessing a 4-ylidene-acyltetronic acid unit, and their biosynthesis were elucidated. Two other new metabolites possessing a chromone skeleton were also isolated and their structures were established as 6, 7-dihydroxy-3-(1'-hydroxy-3'-butanoyl)chromone-5-carboxylic acid and its 1', 2'-dehydrate.

  从Penicillium italicum WEHMER的培养基中分离出了四种新代谢产物：意大利酸、二氢意大利酸、甲基意大利酸酯和意大利酸。对其结构进行了阐明，这些结构具有4-亚烯-酰基四氢吡啶酸单元，并探讨了它们的生物合成。此外，还分离出了另外两种具有色酮骨架的新代谢产物，并确定它们的结构为6, 7-二羟基-3-(1'-羟基-3'-丁酰基)色酮-5-羧酸及其1', 2'-脱水衍生物。
