Fund Project: The authors are grateful to the financial support of the National Natural Sciences Foundation of China (Grant No.39970086) and the Natural Science Foundation of Yunnan (Grant No.98C089M), also thank the members of analytical group in Phytochemistry Laboratory, Kunming Institute of Botany for their measuring spectral data.

Three new cucurbitacins were isolated from the BuOH extract of the rhizomes of Hemsleya lijiangensis. Their structures were elucidated as 23, 24-dihydro cucurbitacin F-16, 25-diacetate (1), 23,24-dihydro cucurbitacin F-16, 25-diacetate-2-O-β-D-glucopyranoside (2), 23, 24-dihydro-cucurbitacin F-16-acetate (3), respectively; by spectral analyses.
