Abstract

The qualitative analytical detection of kaurenic compounds kauradienoic (kauradien-9(11), 16-dienoic acid) (1), monoginoic (2), and kaurenoic acids (3) in the infusion of Montanoa tomentosa Cerv., was carried out using GC-MS and 2D-NMR methods to resolve contradictory HPLC results from previous reports.
