Fund Project: This work was financially supported by a grant from the National Nature Science Foundation of China for Outstanding Young Scientists to Dr. X. J. Hao (No. 39525025). The authors are grateful to Prof. D. Z. Wang, Mr. Y. N. He, Ms. H. L. Liang, Ms. X. M. Zhang and Ms. L. Zhou in Laboratory of Phytochemistry, Kunming Institute of Botany, Chinese Academy of Sciences, for measuring 2D NMR, 1D NMR, HREIMS, IR, UV data, respectively.

Three derivatives of micromelin, named hydramicromelins A-C (1-3), were isolated from the aerial part of Micromelum integerrimum (Buch.-Ham) Roem., respectively.Hydramicromelins A-C (1-3) were epimers which possessed the same plane structure and molecular formula. Their structures were elucidated based on MS and NMR data. The relative configurations of 1-3 were established by NOE analysis.
