Objective:
To study the chemical constituents from the bark of Morus macroura.
Method:
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).
Result:
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).
