1 Solanidine, a steroidal alkaloid, and its glycosides have been reported to have caused poisoning in man and animals. These alkaloids are normally present in small amounts in potatoes. Measurement of solanidine in body fluid would be expected to est

In contradiction to an earlier report we have found that chromium pentoxide etherate solution oxidises tetraphenylcyclopentadienone to a known keto-lactone, which can be obtained more efficiently by chromic acid oxidation; we have been unable to prep

When warmed in aqueous borate or shaken in air with platinum, the quinone A, obtained by reduction of protoaphin-fb, undergoes oxidative coupling to form a dimeric quinone analogous to skyrin. Alternatively, under anaerobic conditions, it is converte

Methylation of erythroaphin-fb gives two isomeric dimethyl ethers, derivatives of perylene-3,9- and -3,10-quinones. Their visible absorption suggests that, in neutral organic solvents, erythroaphins occur principally as perylene-3,10-quinone tautomer
