Abstract A phytochemical investigation was carried out to the root of Aralia echinocauis, and a new neolignan glycoside, 3-{3,5-dimethoxy-4β-d-Glucopyranoside-2-[3-(3-β-d-Glucopyranoside-4-methoxy-phenyl)-allyl]-phenyl}-prop-2-en-1-ol (1), together with a known saponin, araliasaponin II (2) for the… Click to show full abstract

Abstract A phytochemical investigation was carried out to the root of Aralia echinocauis, and a new neolignan glycoside, 3-{3,5-dimethoxy-4β-d-Glucopyranoside-2-[3-(3-β-d-Glucopyranoside-4-methoxy-phenyl)-allyl]-phenyl}-prop-2-en-1-ol (1), together with a known saponin, araliasaponin II (2) for the first time was obtained. The chemical structure of compound 1 was identified mainly by the analysis of NMR including 1D and 2D NMR in combination with High Resolution Electrospray Ionisation Mass (HR-ESI-MS). This paper herein describes the isolation and structural elucidation of compound 1.
