摘要：

Six new ent-kaurane diterpenoids, lungshengenins B-G (1-6), together with three known diterpenoids, lungshengenin A (7), inflexin (8), and lushanrubescinsin C (9), were isolated from the leaves and tender branches of Isodon lungshengensis. Their structures were elucidated by means of spectroscopy, mainly TD and 2D NMR techniques. Lungshengenins A (7), C (2), and G (6) were cytotoxic toward K562 cells, having IC50 values equal to or less than 10 mu g/mL.
