Chemical Constituents of Stems of Acorus tatarinowii / 中国药学杂志

ABSTRACT

OBJECTIVE: To study the chemical constituents from the stems of Acorus tatarinowii Schott. METHODS: The chemical constituents were isolated from the 70% ethanol-soluble extract of the stems of Acorus tatarinowii Schott and purified by a series of column chromatography methods, including MCI, silica gel, Sephadex LH - 20, HPLC and so on, and their structures were identified by physical chemical constants and NMR techniques. RESULTS: A total of twelve compounds were isolated and identified as (7S, 8R) -4, 9'-dihydroxyl-3, 3'-dimethoxyl-7, 8-dihydrobenzofuran-1'-propylneolignan (1), (-) -lyoniresinol (2), dihydrocubebin (3), evofolin B(4), (+) -icariol A2 (5), β-sitosterol(6), (+) -13-hydroxyspathulenol(7), aromadendrane-4β, 10β-diol(8), anomallenodiol( 9), (9CI) -cis-4-(3, 4-dihydroxy-2, 6, 6-trimethyl-1-cyclohexen-1-yl) -2-butanone (10), (3E) -rel-4-[(3R, 4S) -3, 4-dihydroxy- 2, 6, 6 -trimethyl-1-cyclohexen-1-yl]-3-buten-2-one(11), and ixerol B(12), respectively. CONCLUSION: Compounds 2 - 4 and 7 - 12 are isolated from the genus Acorus for the first time, and compound 5 is isolated from this plant for the first time.
