Phytochemical and pharmacological studies on Chinese Changzhu

In addition to twelve known compounds including triterpenoids, steroids, sesquiterpenoids and polyacetylenes, a new natural product, hinesolone was isolated from the rhizhome of Atractylodes chinensis (Compositae). The structure of hinesolone was elucidated on the basis of spectral evidence. Of the isolated compounds, only beta-Eudesmol showed a diuretic effect on S.D. rats.
