Frankia sp. G2（ORS 020604），生长1个月。在不振荡的情况下，产生2种醌型颜料的混合物。其中一个化合物G-2N的结构经化学和物理方法证实为2-甲基-4，7，9，12-四羟基-5，6-二氢苯并[a]并四苯-8，13-二酮。另一个，G-2A，具有相同的结构，在10或11位添加羧基。具有这种环系的天然醌类化合物以前未见报道。
Frankia sp. G2 (ORS 020604), grown for 1 mo. without shaking, produced a mixture of 2 quinonoid pigments. The structure of one, G-2N, was shown by chemical and physical methods to be 2-methyl-4,7,9,12-tetrahydroxy-5,6-dihydrobenzo[a]naphthacene-8,13-dione. The other, G-2A, has the same structure with the addition of a carboxyl group at position 10 or 11. Natural quinones with this ring system were not reported previously.
