Penicillium islandicum Sopp. の生産するアン トラキノン系の一色素 Spot f について

抄録

1.An unknown pigment spot f (designated by Shibata et al.⁵⁾, ) found in a series of anthraquinones in Penicillium islandicum Sopp. NRRL 1036 was purified paperchromatographically and identified as dicatenarin by paperchromatographic studies on degradation products of spot f by means of reductive cleavage (Table 1 and Fig. 1).
2.Based on the facts that the spot f is a dimer of catenarin, and that almost simultaneous appearance and disappearance have been encountered in these two pigments (Table 4 in the Literature 3), the biosynthetic route for the formation of anthraquinones in Penicillium isladicum Sopp. that was proposed in the preceding paper (Fig. 4 in the Literature 4) is modified in part as illustrated in Fig. 2.
