Explaining the Different Types of Terpenes
What are Terpenes?
Terpenes are a diverse class of organic compounds produced by a wide variety of plants, including cannabis and hemp. These compounds are responsible for the distinctive aromas and flavors of many plants, fruits, and spices. Beyond their olfactory appeal, terpenes also play a crucial role in the ecological interactions of plants, acting as deterrents for herbivores, attractants for pollinators, and protectants against pathogens. In cannabis, terpenes contribute significantly to the plant’s therapeutic properties, influencing the effects and benefits of different strains.
Terpenes in Cannabis and Hemp
Terpenes are synthesized in the same glands that produce cannabinoids, such as THC, CBD, CBG, and CBN. These glands, called trichomes, are tiny, hair-like structures that cover the surface of cannabis flowers and, to a lesser extent, the leaves and stems. Trichomes are most densely concentrated on the flowers (commonly called “buds”) of the cannabis plant. These glands contain a resin that is rich in terpenes and cannabinoids, providing the distinctive aroma and potent effects associated with cannabis.
Here’s a more detailed look at how terpenes are found and function in cannabis and hemp:
Trichomes: These are the primary sites of terpene synthesis. Trichomes are glandular structures that appear as tiny, crystal-like hairs on the surface of cannabis flowers. They serve to protect the plant from herbivores and environmental stressors. Within the trichomes, terpenes are produced and stored, along with cannabinoids.
Resin: The sticky resin produced by trichomes is rich in terpenes and cannabinoids. This resin not only gives cannabis its distinctive stickiness but also contains the compounds responsible for its aroma, flavor, and effects.
Flowers (Buds): The highest concentration of trichomes, and thus terpenes, is found on the flowers of the cannabis plant. This is why the buds are the plant’s most aromatic and potent parts. The flowers’ terpene profile can vary significantly between different cannabis strains, leading to a wide range of scents and effects.
Leaves and Stems: While trichomes are also present on the cannabis plant’s leaves and stems, they are found in much lower concentrations than the flowers. As a result, these parts of the plant have fewer terpenes and a less intense aroma.
Genetic and Environmental Factors: The terpene profile of a cannabis plant is influenced by both genetic and environmental factors. Different strains have unique genetic blueprints that dictate their terpene production. Additionally, environmental conditions such as light, temperature, humidity, and soil nutrients can impact the synthesis and concentration of terpenes.
Where Else Can Terpenes Be Found?
Terpenes are ubiquitous in the plant kingdom. They can be found in the following:
Fruits: Citrus fruits like oranges, lemons, and limes, for example, are known for their high terpene content.
Flowers: Many flowers, such as lavender and rose, owe their pleasant aromas to terpenes.
Leaves: Herbs like basil and mint contain significant terpene levels.
Spices: Spices such as black pepper, cinnamon, and cloves are rich in terpenes.
Trees: Pine trees, for example, produce pinene, contributing to the characteristic pine scent.
Key Terpenes and Their Sources
There are more than 20,000 terpenes in the world and over 200 terpenes in the cannabis plants alone. Some terpenes are more well-known than others due to their availability in nature, but there are still a lot of less-known terpenes waiting to be studied.
