Abstract

One new sesquiterpene, (4S,7R,10S)‐2‐oxo‐4,10,11‐trihydroxyguaia‐1(5)‐ene (1), and five lignans, kadsuralignan J (2), isovaleroylbinankadsurin A (3), schizandrin O (4), futokakadsurin C (5), and arisantetralone (6) were isolated from the roots of Kadsura induta. Their chemical structures were revealed by MS, 1D and 2D NMR spectra in comparison with the reported data. The absolute configuration of compound 1 was determined by calculation of its theoretical ECD spectra and compared with the experimental results.
