    • No CD spectrum of isoknipholone anthrone has ever been reported. More recently, however, a sample of isoknipholone (P: M = 85: 15) available by isolation from B. frutescens 19 was reduced to isoknipholone anthrone in the authors' lab. Its resolution on a chiral phase with chiroptical analysis online, by HPLC-CD, revealed that it was also P-configured. 19 Note that some compounds, 27 and 28, though stereochemically analogous, e.g., to the P-configured metabolite 32, 39,54 possess the M-configuration due to the Cahn-Ingold-Prelog formalism, but have erroneously been denoted in the literature. 18 Still, in combination with the configurational revision, 4 the descriptors of 27 and 28 remain the same, i.e., M
