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.

## Abstract The ^13^C NMR spectra were determined and signals assigned to the various carbons of the alkamines veracevine, germine and zygacine derived from steroidal alkaloids of the ceveratrum class. Assignment of signals was aided by analysis of the partially relaxed spectrum of cervagenine 9,12
## Abstract The ^13^C n.m.r. spectra of some 2‐heteroadamantanes and 1‐substituted 2‐heteroadamantanes are reported. The influences of the heteroatoms in the adamantane framework, and those of the substituents attached to it, on the ^13^C chemical shifts of the adamantane carbons are investigated a
## Abstract The ^13^C chemical shift data of a series of ketone, alcohol and ester derivatives of D‐homoandrostane are reported. Homologation effects are discussed, as well as substituent effects on the homologated structures.
