[Studies on chemical constituents from the bark of Morus macroura].
OBJECTIVE
To study the chemical constituents from the bark of Morus macroura.


METHODS
The compounds were isolated with silica gel column chromatography and their structures were elucidated on the basis of chemical evidences and spectral analysis (IR, EI-MS, 1H-NMR, 13C-NMR).


RESULTS
Five compounds were identified as alpha-amyrin acetate (1), gult-5-en-3 beta-yl acetate (2), 3 beta-hydroxylup-20 (29)-en-28-oic acid (3), 3 beta-hydroxylup-12-en-28-oic acid (4), butyrospermol acetate (5).
