摘要

A new octadecanoyl diterpenoid glycoside, (E)-8 alpha,15-dihydroxy-15-(3S-hydroxy-octadecanoyl)-13-labdene-8-O-alpha-L-arabinopyranoside(1), was isolated from the aerial parts of Conyza blinii, and the structure was identified on the basis of a detailed spectroscopic analysis, including 2D NMR spectrometry and HRESI-MS.
