ABSTRACT
The chemical constituents of Zingiber officinale peel were isolated and purified by various chromatographic separation techniques such as Diaion HP-20, MCI Gel CHP-20, Sephadex LH-20, ODS, silica gel and semi-preparative HPLC. Seven terpenoids were identified by physicochemical properties and spectral data (4R,6S)-1-(hydroxymethyl)-5,5-dimethylbicyclo[3.1.1]hept-2-en-4-ol (1), 4-(hydroxymethyl)-1-isopropylcyclohex-2-ene-3,4-diol (2), 3,5,6-trihydroxy-7-megastigmen-9-one (3), 3-(3-hydroxybutyl)-2,4,4-trimethyl-2,5-cyclohexadien-1-one (4), angelicoidenol (5), grasshopper ketone (6), and dihydrophaseic acid (7), in which compounds 1, 2 are new compounds, named (4R,6S)-1-(hydroxymethyl)-5,5-dimethylbicyclo[3.1.1]hept-2-en-4-ol and 4-(hydroxymethyl)-1-isopropylcyclohex-2-ene-3,4-diol, and compounds 3-7 were obtained from this plant for the first time.
