Two new sterols, 3β,7α,16β-trihydroxy-stigmast-5,22-diene (1), 3β,7α,16β-trihydroxy-stigmast-5-ene (2), were isolated together with six known compounds, ergosta-5,24(28)-dien-3β,7α-diol (3), ergosta-5,24(28)-dien-3β,7β,16β-triol (4), β-amyrone (5), β-amyrin (6), 11α,12α-epoxy-14-taraxeren-3-one (7), and 6-guaiene-4α,10α-diol (8) from the EtOH extract of the bark of Amoora yunnanensis (H. L. Li) C. Y. Wu. Their structures were deduced on the basis of spectral data.
