Two new triterpenoids from the roots of Pinus densiflora
Two new triterpenoids from the roots of Pinus densiflora is a scholarly work by Junnosuke Otaka and Yushi Futamura, published in 2016 in ''Bioscience, Biotechnology, and Biochemistry''. The main subjects of the publication include triterpene, biology, botany, traditional medicine, chemistry, diterpene, Pinus densiflora, and medicinal plant. Abstract 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).
