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.
