Chemical Structure
Basic Info
The tricyclic sesquiterpene longifolene has a content between 60% and 78% of Masson pine heavy Turpentine. Longifolene isomerizes into isolongifolene. Isolongifolene, when oxidized, produces isolongifoleanone. This has a woody and iris like aroma. It is used to flavor soaps and cosmetics. The W-acetoxymethyllongifolene obtained from longifolene has the ability to enhance and fix fragrance. W-hydroxymethyl is a woody ambergris with a sweet fruity scent. It’s used to mix floral and woody flavors.
Currently, domestic production of longifolene with high purity is mostly separated and purified using heavy turpentine. Heavy turpentine is a mixture of monoterpene hydrocarbons and monoterpene alcohols. It also contains sesquiterpenes such as longifolene, caryophyllene, sesquiterpene oxided compounds, and diterpenes. Vacuum distillation is unable to separate longerifolene in excess of 80%. Longifolene is difficult to separate from caryophyllene because they are both isomers that have similar boiling points. Caryophyllene can affect the use of longifolene. To obtain longifolene that contains more than 80% caryophyllene, it must be chemically modified.

1. Applications in the fragrance industry
Longifolene, a natural fragrance ingredient of great value, is renowned for its woody-pine scent. It is a key ingredient in high-end fragrances for shampoos and shower gels. The dosage ranges from 0.5 to 3%. The development of new fragrance molecules, such as its derivatives like longifolene, has increased its value in recent years.
2. Applications in the medical field
This sesquiterpene has a tricyclic structure of [4.4.0.02,7] and is a “star material” in the synthesis of chiral medicines.
Lead compounds that are selective for COX-2 can be synthesized by oxidation reactions
Anti-tumor drug: Its derivatives have significant activity against the breast cancer cell MCF-7 line (IC50=10mM).
After structural modification, it is possible to obtain active molecules that can penetrate the blood brain barrier.
More than 20 drugs that use longifolene in their starting materials are currently in the clinical stage. Its main advantages are: Rich chiral centres; Good structural modification; Safety of natural source
3. Functional material development
Longifolene is a unique material in materials science.
Polymer modification: adding 1-3% to PLA can increase the heat resistance (HDT increased from 15-20).
Photocuring Materials: Derived monomers of acrylate have excellent curing rate (>95% conversion/30s).
Longifolene, a biobased leveling agent, can reduce surface tension between 28 and 32mN/m.
Adhesives: Hydrogenated resins as tackifying products increase peel strength 40-60%
4. Innovative agricultural applications
Green agriculture is important for the environment.
Longifolene is a botanical pesticide that has a repellency of 70-85% against aphids, red spiders, and other insects.
Pine wood nematodes can be attracted by specific insect pheromones.
Synergy between pesticides: Pyrethroids and pyrethroids compounding can reduce the LC50 by 30-50%
Modified nanoemulsions improve drug efficacy by a significant margin.
5. Research and emerging fields
Asymmetric Synthesis: Used as a template for constructing quaternary carbon centres (ee values >99%).
Total synthesis of diterpenoids: Longifolene as a key intermediate
Biofuels have a high combustion value (40MJ/kg).
Cosmetic active ingredients: Acetylated products are effective in reducing wrinkles (collagen synthesis increased by 35%)
