Identification of Endogenous Gibberellins from Salix pentandra

Abstract
Gibberellins A1, A19, A20, and A29 have been identified by sequential high-performance liquid chromatography retention time (Rt) and combined gas chromatography-mass spectrometry (Rt and characteristic mass spectra) from elongating shoots of Salix pentandra L. Gibberellins A1 and A19 were also detected in purified extracts from male and female flowers (catkins) of S. pentandra.
