    • Isoknipholone obtained in this work occurred as a 85:15 (P/M) enantiomeric mixture (Supporting Information. Figure S1) in comparison to a sample previously isolated from the same plant (52:48, P/M)[3] The absolute configuration of isoknipholone anthrone had as yet notbeen established, which is,in part, due to the fact that the parent isoknipholone available was a nearly racemic mixture (52:48, P/M, 3] Thus, reduction of the now available P-enriched sample of isoknipholone (85:15, P/M) to isoknipholone anthrone allowed establishment of the absolute configuration by HPLC-CD analysis on a chiral phase, revealing isoknipholone anthrone to be P-configured Supporting Information, Figure S2
