[Abstract]
Objective To investigate the chemical constituents in the roots and rhizomes of Curacuma aromtica. Methods The chemical constituents were separated and purified by silica gel, Sephadex LH-20 column chromatography, preparative HPLC, and so on. Their structures were determined by physicochemical constants and spectral analyses. Results Seventeen compounds were obtained and identified as curdione (1), β-sitosterol (2), stigmasterol (3), triaconatanoic acid (4), gweicurculactone (5), curcumenol (6), procurcumenol (7), eudesmane-3, 6-dione (8), lupeol (9), curcumin (10), demethoxycurcumin (11), aerugidiol (12), zedoarondiol (13), voleneol (14), uracil (15), curcumol (16), and curcumenone (17). Conclusion Compounds 4, 5, 8, 9, 14, and 15 are isolated from the plant for the first time.
