Abstract

A chemical investigation of the roots of Pteroxygonum giraldii led to the isolation of a new arborane‐type triterpene, pteroxygonumnol A (1), a new myricetin glycoside, myricetin 3‐O‐β‐D‐galactopyranoside 3′‐O‐β‐D‐xylopyranoside (2), and a group of phenolic lipids, 3–6, along with four known phenolic compounds, (−)‐epigallocatechin, (−)‐epigallocatechin gallate, gallic acid, and 2‐(4‐hydroxyphenyl)acetic acid. Their structures were elucidated on the basis of extensive spectroscopic analyses.
