Pinene is a colorless liquid hydrocarbon that occurs naturally in pine trees, rosemary, and cannabis. It has two isomers - alpha-pinene and beta-pinene. Pinene has several health benefits and can be used to make essential oils for perfumes, cosmetics, soaps and food flavoring. It is synthesized from geranyl pyrophosphate and is widely found in over 400 plant species, especially in the resins of pine trees. Pinene has analgesic, antibacterial, anti-inflammatory, and antioxidant properties and is used in the chemical industry where selective oxidation produces derivatives used in perfumery.

2. PINENE
Pinene a colourless liquid
hydrocarbons, α-pinene and β-pinene,
occurring as major components of the
essential oil of pine trees and used as a
chemical raw material. Both compounds
belong to the isoprenoid series and have
the molecular formula C10H16. Health
Benefits: Asthma, antiseptic, cancer-
killing, and memory-enhancing

3. PINENE
It is possible to make essential cannabis oil through steam
extraction to use in perfumes, cosmetics, soaps, candles
and also as a flavouring agent in cooking, for candies and
beverages.

4. Isomer of pinene
It have two isomers:
1. Alpha pinene 2. Beta pinene
Both isomers are used by many insects
Naturally present:Pinene exist in more than 400 kinds of natural plants, the conte
nt of alpha-pinene in turpentine about 60%~70%, beta-
pinene content of 20%~30%.

5. Source of pinene
Pinene is a bicyclic terpene known as a monoterpene.it is the main
terpene in pine trees, which gives them their characteristic scent.its a
major constituent of turpentine and is also found in high amounts in
rosemary and cannabis .both forms are present in many essential oils
but are mostly obtained from tupentine,and The amount produced
depends on the temperature and available sunlight.

6. Synthesis of pinene
α-Pinene and β-pinene are both produced from geranyl pyrophosphate,
via cyclisation of linaloyl pyrophosphate followed by loss of a proton
from the carbocation equivalent.

8. Derivative of pinene

9. USES
It has activity as
Analgesic-Relieves pain
Antibactterial-Slows bacterial growth.
Anti-inflammatory-reduce inflammation systemically.
Anti-proliferative-inhibits cancer cell growth.
Antioxidant-prevents oxidation damage to other
molecules in the body
In chemical industry
selective oxidation of pinene with some catalysts gives many
compounds for perfumery, such as artificial odorants. An important
oxidation product is verbenone, along with pinene oxide, verbenol and
verbenyl hydroperoxide.
