OBJECTIVE
To study the chemical constituents of the stem and leaves from Curcuma wenyujin.
METHODS
The compounds were isolated by silica gel column chromatography in associating with Sephadex LH -20 chromatography. While their structures were identified on the basis of spectroscopic date.
RESULTS
Nine sesquiterpenes were isolated and identified. Their structures were identified as curdione (1), neocurdione (2), trans, trans-germacrone (3), cis, trans-germacrone (4), curcumenone (5), curcumadione (6), isoprocurcumenol (7), glechomanolide (8) and (1R, 10R)-( -)-1, 10-dihydrocurdione (9).
CONCLUSIONS
All of these compounds were isolated from the stems and leaves of this plant for the first time.
