Chemical investigation of the roots of Pinus densiflora led to the isolation of two new triterpenoids, (24S)-3β-methoxy-24,25-epoxy-lanost-9(11)-ene (1) and 29-acetoxy-3α-methoxyserrat-14-en-21α-ol (2), together with three known serratene-type triterpenoids (3-5) and four known diterpenoids (6-9). Their structures were determined by spectroscopic analyses.
