Jc. Liao et al., Assignment of the H-1 and C-13 NMR spectra of a new antibacterial bisabolane sesquiterpene by two-dimensional NMR techniques, SPECT LETT, 33(2), 2000, pp. 235-243
A new antibacterial bisabolane sesquiterpene, 1 beta-acetoxy-2 beta,8-diang
eloyloxy-3 beta-hydroxy-4 alpha-chloro-10, 11-expoxybisabol-7(14)-ene (1),
was isolated from Ligularia thyrsoidea and its structure was elucidated by
2D NMR techniques.
