Two new ent-kaurane diterpenoids, minheryins H (1) and I (2), were isolated from the leaves of Isodon henryi. Their structures were elucidated by means of spectroscopic analysis, including 2D NMR spectra.
Three new ent-kaurene diterpenoids, adenanthins N, 0 and P (1-3), and four known diterpenoids, leucophyllin E (4), glabcensin C (5), adenanthin A (6), leucophyllin B (7), together with a highly unsaturated fatty acid,...
