## Abstract ^1^H NMR spectra of eight naturally occurring brassinosteroids, plant hormones with a steroid skeleton, and five synthetic analogues were analysed by COSY and long‐range COSY measurements. Based on the ^1^H resonances, the ^13^C signals were assigned by a combination of CH COSY and lon

Abstract
The ^1^H and ^13^C NMR spectra of the two phytohormones, brassinolide and 24‐epi‐brassinolide, and the two synthetic analogues 22,23,24‐trisepi‐brassinolide and (22__S__,23__S__)‐28‐homo‐brassinolide, were assigned using 1D and 2D NMR techniques. Independent assignment strategies are presented for the ^1^H and ^13^C chemical shifts of the steroidal side‐chain.

Detailed analysis of the 'H and 13C NMR spectra of three natural quinone-methide triterpenoids, pristimerin, tingenone and 20-hydroxytingenone, was carried out by the application of two-dimensional H-'H and ' H-13C shift correlation techniques. Some previous 'H and "C assignments have been revised.
