Chemical constituents in roots and rhizomes of Curacuma aromatica / 中草药

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.
