What Are Phytocannabinoids? Understanding Plant-Derived Cannabinoids

What are phytocannabinoids? Phytocannabinoids are naturally occurring chemical compounds produced by cannabis and hemp plants. The word “phyto” comes from the Greek word for “plant,” meaning phytocannabinoids are cannabinoids that originate from plants rather than being produced naturally within the human body or synthesized in a laboratory.

Scientists have identified more than one hundred phytocannabinoids, each with its own chemical structure and characteristics. These compounds are primarily produced in the resin glands, known as trichomes, found on cannabis flowers. As research continues to expand, phytocannabinoids remain a major focus in cannabis biology, plant chemistry, and hemp science.

This guide explains what phytocannabinoids are, how they are produced, and why they are important in cannabinoid research.

What Are Phytocannabinoids?

Phytocannabinoids are cannabinoids naturally synthesized by hemp and cannabis plants.

Unlike endocannabinoids, which are produced within the human body, phytocannabinoids originate entirely from plant tissues.

These naturally occurring compounds contribute to the chemical diversity of cannabis and are commonly studied alongside terpenes, flavonoids, and other plant constituents.

Where Are Phytocannabinoids Produced?

Phytocannabinoids are primarily produced inside glandular trichomes, the microscopic resin glands that cover mature cannabis flowers.

These trichomes also produce:

• Terpenes
• Flavonoids
• Aromatic plant compounds
• Resin

How Phytocannabinoids Are Formed

Phytocannabinoids are created through a natural biochemical process known as cannabinoid biosynthesis.

During this process:

• Plant enzymes produce precursor molecules.
• Cannabigerolic acid (CBGA) acts as a central precursor.
• Specialized enzymes convert CBGA into acidic cannabinoids such as THCA, CBDA, and CBCA.
• Natural processes such as decarboxylation transform these compounds into their better-known forms.

Major Phytocannabinoids

Some of the most recognized phytocannabinoids include:

CBD (Cannabidiol)

One of the best-known hemp-derived cannabinoids studied by researchers worldwide.

Learn more in What Is CBD.

THC (Tetrahydrocannabinol)

A naturally occurring cannabinoid found in cannabis plants.

Read our guide on What Is THC.

CBG (Cannabigerol)

Often referred to as the “parent cannabinoid” because of its role in cannabinoid biosynthesis.

Learn more in CBG Cannabinoids.

CBC (Cannabichromene)

A naturally occurring phytocannabinoid produced during cannabinoid biosynthesis.

Read What Is CBC.

CBN (Cannabinol)

A cannabinoid formed as THC naturally changes over time.

Phytocannabinoids and the Endocannabinoid System

Researchers study phytocannabinoids because of their interaction with the body’s endocannabinoid system (ECS).

The ECS consists of:

• CB1 receptors
• CB2 receptors
• Endocannabinoids
• Enzymes involved in cellular signaling

Understanding the ECS helps explain why phytocannabinoids remain an important area of scientific research.

Phytocannabinoids vs Endocannabinoids

Although both interact with the endocannabinoid system, they have different origins.

Phytocannabinoids:

• Produced by hemp and cannabis plants
• Naturally occurring plant compounds
• Found in trichomes

Endocannabinoids:

• Produced naturally by the human body
• Function as internal signaling molecules
• Participate in normal physiological processes

Understanding this distinction helps clarify cannabinoid terminology.

Why Researchers Study Phytocannabinoids

Scientists continue studying phytocannabinoids to better understand:

• Cannabis biology
• Plant genetics
• Cannabinoid chemistry
• Biosynthesis
• Plant breeding
• Hemp science

As analytical technology advances, researchers continue discovering new phytocannabinoids and learning more about their chemical properties.

Conclusion

Phytocannabinoids are naturally occurring cannabinoids produced by hemp and cannabis plants through cannabinoid biosynthesis. Found primarily in glandular trichomes, these compounds form the foundation of cannabinoid science and continue to be extensively researched for their chemical characteristics and interactions with the endocannabinoid system.

As scientific understanding grows, phytocannabinoids remain central to cannabis biology, plant chemistry, and hemp research.
