Abstract

The main chemical constituents from Acori Tatarinowii Rhizoma were isolated and purified using the macroporous resin,microporous resin(MCI) and octadecylsilyl silica gel(ODS) column chromatography, as well as semi-preparative high performance liquid chromatography. Their chemical structures were elucidated by spectroscopic analyses including mass spectrometry(MS),nuclear magnetic resonance(NMR), ultraviolet(UV), infrared(IR) and circular dichoism(CD) combined with literature data.A total of 11 compounds were isolated and identified, including 4 lignan glycosides, 2 benzyl alcohol glycosides, 4 flavonoid glycosides, and 1 α-tetralone glycoside:(7S,8R)-dihydrodehydrodiconiferyl alcohol 9-O-β-D-glucopyranosyl-9'-O-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranoside(1),(7S, 8R)-dihydrodehydrodiconiferyl alcohol 9-O-β-D-glucopyranoside(2),(7S, 8R)-dihydrodehydrodiconiferyl alcohol di-9, 9'-O-β-D-glucopyranoside(3),(+)-lyoniresinol 3α-O-β-D-glucopyranoside(4), benzyl alcohol O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside(5), benzyl alcohol O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside(6), 3'-O-methylepicatechin 7-O-β-D-glucopyranoside(7), 3'-O-methylcatechin 7-O-β-D-glucopyranoside(8), apigenin 6-C-β-D-glucopyranosyl-7-O-β-D-glucopyranoside(9), isoscoparin 7-O-β-D-glucopyranoside(10), and(4R)-8-hydroxy-α-tetralone-4-O-β-D-glucopyranoside(11). Compound 1 is a new neolignan glycoside, and compounds 2-5 and 7-11 are isolated from genus Acorus for the first time.

Keywords: Acori Tatarinowii Rhizoma; benzyl alcohol glycosides; flavonoid glycosides; neolignan glycosides.
