Methoxy-serratenes in a soil under conifers and their potential use as biomarkers of Pinaceae

► A number (12) of methoxy-serratenes were detected in soils developed under spruce and pine. ► Serratenoids can be produced by moss, gymnosperms and angiosperms, according to literature data. ► Conversely, methoxy-serratenes are exclusively reported in Pinaceae. ► Methoxy-serratene detection in soils attests to their resistance to early diagenesis. ► Their detection in sediments could help unravel Pinaceae forest dynamics through time.
