Abstract:Two new named maoecrystal F(1) and G(2) and seven known ent-kaurene diterpenoids were isolated from the leaves of Rabdosia eriocalyx (Dunn) Hara collected at Xundian County, Yunnan Province, and their structures were determined by spectroscopic analysis. Maoecrystal F and G are elucidated as ent-7α, 15α-dihydrooxyl- lβ,6α-diacetoxyl-7β, 20-epoxy-16-kaurene (1) and ent-7α,15α-dihydroxyl-6α-ace-toxyl-7β, 20-epoxy-16-kaurene(2), respectively.
