Four new patchoulol derivatives, 8 α,9 α-dihydroxypatchoulol (), 3 α,8 α-dihydroxypatchoulol (), 6 α-hydroxypatchoulol (), and 2 β,12-dihydroxypatchoulol (), were isolated from the aerial part of Pogostemon cablin (Labiatae), together with nine known compounds, sesquiterpenoids - and flavonoids -. Their structures were elucidated by detailed spectroscopic analysis, using 1D- and 2D-NMR techniques.
