چکیده
IT was recently shown [Clutterbuck et al., 1934] that Penicillium Charlesii G. Smith, when grown on nutrient solutions containing glucose, produces two new polysaccharides, mannocarolose [Haworth et al., 1935] and galactocarolose, together with a number of new organic acids. The polysaccharides were isolated by precipitation from the evaporated metabolism solution with acetone, and the acids by solvent extraction of the filtrate from the polysaccharides, after removal of the acetone. Of these acids, carolic acid CgH1004 (I), carolinic acid CgH1006 (II), carlic acid C10H1006 (III), and carlosic acid ClHlO206 (IV) have been shown [Clutterbuck et al., 1935, 1, 2] to have the following molecular constitutions:

Bracken, Pocker & Raistrick (1954) described the isolation of two nitrogen-containing products from different cultures of Penicillium cyclopium Westling. One of these, previously isolated from Penicillium viridicatum Westling by Cunningham & Freeman (1953) and named viridicatin, C15H11NO2, was shown to be 2,3-dihydroxy-4phenylquinoline or its keto-tautomer (I), by degradative methods and unequi...
