## Abstract The ^13^C chemical shift data of a series of ketone, alcohol and ester derivatives of Dβhomoandrostane are reported. Homologation effects are discussed, as well as substituent effects on the homologated structures.
The =C chemical shifts of a series of isoflavones having hydroxy, acetoxy, methoxy and methylenedioxy substituents are compared. Some general relationships between substitution patterns and chemical shifts, useful for the identitication of naturally occurring isoflavones, are outlined.
