-(+)-Longifolene is a sesquiterpene that occurs up to 30% in the resin of Pinus roxburghii Sarg., the Indian longleaf pine or chir pine. It is used in the perfume industry to manufacture isolongifolene epoxide, which ist is isomerized to the corresponding ketone isolongifolanone (Piconia; commercial odorant; woody earthy camphoraceous scent), which is also ketalized with ethylene glycol to the commercial odorant Ysamber K (woody amber scent). \\
