title: New ent-abietane and ent-kaurane diterpenoids from Isodon rubescens.
abstract: Five new ent-abietane diterpenoids, ent-abierubesins A-E (1-5), and two new ent-kauranoids, hubeirubesins A and B (6, 7), together with three known diterpenoids (8-10), were isolated from the aerial parts of Isodon rubescens. Their structures were identified by means of extensive spectroscopic analysis, and the absolute stereochemistry of 1 was determined by single-crystal X-ray diffraction experiment.
