Summary

1. The following compounds have been isolated from the oleoresin ofPinus koraiensis Sieb. et Zucc., in addition to those described previously: cis-abienol, labd-8(20),13-dien-15-ol, (+)-manoyl oxide, epimanoyl oxide, and 7α-hydroxydehydroabietinol (in the form of the diacetate). The structure of the last-mentioned, previously unknown, diterpenoid has been shown by chemical transformations and by spectroscopy.

2. It has been established that the cembrene, isocembrene, pinacenes, neoabienol isolated previously and the 18-norcembra-2,7,11-trien-4-one now isolated for the first time are secondary products formed in the storage and treatment of the oleoresin.
