Pumilol, a Diterpenoid with a Rare Strobane Skeleton from Pinus pumila (Pinaceae)
Get PDFPumilol (1), a strobane diterpenoid, reported herein for the first time, was isolated from the bark of Pinus pumila (Pall.) Regel (Siberian Dwarf Pine or Japanese Stone Pine), along with 17 known compounds including serratane triterpenoids, not previously reported from this species, and four ferulate derivatives. The absolute configuration of pumilolwas established using HR-ESI-MS, NMR, the DP4+ probabilities and by comparison of the experimental and calculated electronic circular dichroism (ECD) spectra. Labda-8(17),13-dien-15-oic acid (4), bornyl (E)-4-hydroxycinnamate (14) and bornyl (E)-ferulate (15) showed activity against S.aureus and/or E.faecalis with MIC90 values 12.5-50m.Peer reviewe
