摘要：

Two new ent-kaurane diterpenoids, 16( S)-hydroxymethyl-1alpha, 6beta, 7beta, 11beta-tetrahydnoxy-7a, 20-epoxyent-kauran-15-one (1) and 16 ( R)-hydroxymethyl-1alpha, 6beta, 7beta, 14beta-tetrahydroxy-7alpha, 20-epoxy-ent-kauran-15-one (2), named rubescensins F (1) and G (2), respectively, were isolated from the EtOAc extract of the dried leaves of Isodon rubescens ( Hemsl.) Ham collected in Jiyuan Prefecture, Henan Province, together with fourteen known compounds lasiodonin (3), oridonin (4), ponicidin, rubescensins C and D, rabdoternin C, wikstroemioidin B, enmenol-1alpha-O-beta-D-glucoside, enmenol, pedalitin, salicylic acid, ursolic acid, beta-sitosterol and daucosterol. Their structures were determined on the basis of spectral data.
