Abstract
The composition of diterpenoids isolated from the aerial parts of Sigesbeckia pubescens growing in Primorsky Territory was investigated. Diterpenoids -glucopyranosyl-18-acetoxy-16, 17-dihydroxykauran-19-oate (1), 15-O-malonylkirenol (2), and 16-O-malonylkirenol (3) were isolated by extraction and preparative column chromatography. The diterpenoids 1-3 were new compounds, the structures of which were established using NMR spectroscopy and mass spectrometry.
