Abstract:From the ethanolic extract of the aerial part of Rabdosia leucophyUa (Dunn) Hara, five compounds were isolated and identified as leucophyllin E (1), leucophyllin F (2), xindongnin A (3), maslinic acid (4) and dausterol (5), by spectral and chemical evidence. Among them, I and 2 were new compounds and the structure of 2 was also confirmed by X-ray crystallographic analysis.
