Zanthosides A–D: Four aromatic glucosides from the leaves of zanthoxylum ailanthoides

Abstract

From the leaves of Zanthoxylum ailanthoides, four new phenolic glucosides, termed zanthosides A–D (1–4), were isolated. Their structures were elucidated by means of spectroscopic evidence. Zanthoside A was enzymatically hydrolyzed and thus the aglycone obtained was found to be (1′S,2′R)-(−)-trans-decursidinol, isolated from Angelica decursiva.
