[Studies on chemical constituents of Curcuma aromatica salisb].

To study the effective ingredients of Curcuma aromatica. Solvent extraction was used. The constituents were isolated with resin D-101 silica gel column and thin-layer chromatography, and the structures were elucidated by physico-chemical properties and spectral analysis. Curdione, neocurdione, curcumol, tetramethylpyrazine and (R)-(+)-1,2-hexadecanediol were isolated from C. aromatica. Neocurdione and (R)-(+)-1,2-hexadecanediol were isolated from C. aromatica for the first time, and was isolated from Curcuma and reported for the first time.
