how to extract terpenes from plants


Understanding the Process of Extracting Terpenes from Plants

The aroma and flavor we experience in many plants, herbs, and fruits are largely due to organic compounds known as terpenes. They are not only responsible for the unique scents and tastes but also provide a range of health benefits. This article will guide you on how to extract terpenes from plants.

What are Terpenes?

Terpenes are natural compounds found in a wide variety of plants, including cannabis, fruits, and vegetables. They contribute to the plants' unique flavors, aromas, and colors. Beyond their sensory appeal, terpenes also have potential therapeutic properties.

Methods of Extracting Terpenes from Plants

There are several methods one can use to extract terpenes from plants. The two most common methods are steam distillation and solvent extraction.

Steam Distillation

Steam distillation is a traditional method used to extract essential oils and terpenes from plants. In this process, steam is passed through plant material, causing the plant cells to burst and release their oils, including terpenes. The steam and oil mixture is then condensed back into a liquid, and the oil is separated.

Solvent Extraction

Solvent extraction is another common method used to extract terpenes. In this process, a solvent like ethanol, butane, or CO2 is used to dissolve the plant’s terpenes. The solvent is then evaporated, leaving behind the terpenes. However, this method can sometimes result in the loss of some terpenes due to the heat used in the process.


Extracting terpenes from plants can seem like a complex process, but with the right knowledge and tools, it can be a rewarding endeavor. Whether you're interested in the therapeutic benefits of terpenes or simply want to capture the essence of your favorite plant's aroma, understanding these extraction methods is a great place to start.

How to Extract Terpenes from Plants at Home

While commercial extraction of terpenes is best left to professionals, there is a simple method you can try at home using citrus fruits.

Cold Press Extraction

Also known as expression or scarification, this method is commonly used for citrus peels where terpenes are abundant. Here's a step-by-step guide:

  1. Choose a ripe citrus fruit of your choice.
  2. Wash and dry the fruit to remove any dirt or pesticides.
  3. Peel off the skin of the fruit, being careful not to include the white pith as it can add bitterness.
  4. Place the peels in a glass jar and muddle them to start releasing the oils.
  5. Seal the jar and let it sit for a couple of days in a cool, dark place.
  6. After a few days, strain the mixture through a cheesecloth. The resulting liquid is your citrus terpene extract.

Safety Precautions When Extracting Terpenes

While extracting terpenes at home can be fun and rewarding, it's important to remember that safety comes first. Always work in a well-ventilated area, wear protective clothing, and avoid direct contact with the skin or eyes. If you're using a solvent for extraction, make sure it's food-grade and safe to use.

The Value of Terpenes

Terpenes are an incredible gift from nature that can be used in aromatherapy, perfumes, cooking, and natural health remedies. By learning how to extract terpenes from plants, you can harness the power of these beneficial compounds right at home.


Whether you're a hobbyist, a natural health enthusiast, or someone interested in the science behind plant extracts, understanding how to extract terpenes is a fascinating and useful skill. Remember, practice makes perfect, and safety should always be your top priority.

The Benefits of Terpenes

Aside from their aromatic and flavor-enhancing properties, terpenes have been studied for their potential therapeutic benefits. Some terpenes are believed to have anti-inflammatory, antibacterial, and even anticancer properties. They can also enhance the effectiveness of certain medications.

Storing Your Extracted Terpenes

Once you've successfully extracted your terpenes, it's important to store them properly to maintain their potency. Keep them in airtight, dark glass containers and store in a cool, dark place. Exposure to light, heat, and air can degrade terpenes over time.

Incorporating Terpenes into Your Lifestyle

There are numerous ways to use your extracted terpenes. You can add them to homemade candles or soap for a natural fragrance, use them in cooking to enhance flavors, or mix them into massage oils for a relaxing aromatherapy session.

Final Thoughts

Extracting terpenes from plants is an interesting and rewarding process that allows you to explore the fascinating world of natural compounds. With this guide, you're well on your way to understanding and harnessing the power of terpenes. Remember, safety is paramount, and the quality of your end product will always depend on the quality of your starting materials. Happy extracting!

Exploring Different Types of Terpenes

There are over 200 types of terpenes identified in various plants, each with unique properties. Some of the most common terpenes include limonene (found in citrus fruits), pinene (pine trees), and linalool (lavender). Experimenting with different plant sources can yield a wide variety of scents and flavors.

The Role of Terpenes in the Ecosystem

Beyond their uses for humans, terpenes play crucial roles in the ecosystem. They act as natural pest deterrents, protect plants from environmental stresses, and even contribute to the formation of clouds and precipitation.

The Future of Terpene Research

Research into the potential health benefits of terpenes is ongoing. Scientists are studying how these compounds can be used in treatments for conditions like anxiety, depression, pain, inflammation, and cancer. As we continue to learn more about these fascinating compounds, the possibilities for their use will only grow.


Whether you're interested in natural health, cooking, or just love the scents and flavors of plants, understanding how to extract terpenes from plants opens up a world of possibilities. Remember, the key to successful extraction is patience, practice, and always prioritizing safety.
