A revision of the 13C NMR spectral assignment of globulol

Abstract

Complete assignment of the 13C NMR spectrum of the aromadendrane-type sesquiterpene alcohol, globulol was reported, however, it still remained to be ambiguous. We report here the unambiguous and complete assignment of the H and 13C NMR spectra of (+)-globulol, which was isolated from the liverworts Plagiochila ovalifolia, Neotrichocolea bissetii and Pallavicinia subciliata.
