Two pairs of phenolic enantiomers from the leaves of Eucommia ulmoides Oliver.

Abstract

Two pairs of new phenolic enantiomers, (+)-eucophenolic A (1a), (-)-eucophenolic B (1b), (-)-eucophenolic C (2a), (+)-eucophenolic D (2b) were isolated from the leaves of Eucommia ulmodies Oliver by chiral enantiomeric resolution. Their structures were elucidated based on extensive spectroscopic analysis. The absolute configurations of 1a/1b and 2a/2b were… (More)
