Abstract

Two sesquiterpenoids, spatulenol and (−)‐caryophyllene oxide, were isolated from the hexane extract of the Brazilian plant Vernonia mollissima Don. The ^1^H and ^13^C NMR spectra of these compounds have been reassigned completely by COSY experiments and ^13^C/^1^H shift correlation diagrams.

A careful NMR analysis with full assignment of the 1 H and 13 C spectral data for two minor saponins isolated from stems of Cordia piauhiensis is reported. These saponins were isolated by high-performance liquid chromatography and characterized as 3b-O-[a-L-rhamnopyranosyl-.1 → 2/-b-D-glucopyranosyl

The total assignment of the 13C and the ' H NMR spectra of four derivatives of 1,3diaza-2,4-diboranaphthalene has been performed. The interpretation of the spectra was achieved from the concerted application of direct and long-range heteronuclear chemical shift correlation and homonuclear COSY two-d
