What is terpenes?

Terpenes are a large and diverse class of organic compounds produced by various plants, particularly conifers. They play a significant role in the natural world, contributing to the aroma and flavor of many plants and serving various ecological functions, such as attracting pollinators and deterring herbivores.

In addition to their ecological roles, terpenes have gained attention in the fields of medicine and natural products due to their potential therapeutic properties. Different terpenes have been studied for their anti-inflammatory, analgesic, antimicrobial, and psychoactive effects, among others.

In the context of cannabis, for example, terpenes contribute to the distinctive scents and flavors of different strains and may also influence the effects of the plant's cannabinoids, such as THC and CBD, through a phenomenon known as the "entourage effect." Some common terpenes found in various plants include myrcene, limonene, pinene, and linalool, each with its own unique scent and potential benefits.

History of terpenes?

The history of terpenes is closely intertwined with the development of chemistry, botany, and the use of natural products in medicine and industry. Here’s a broad overview of the historical timeline and key developments related to terpenes:

Ancient and Medieval Periods

• Prehistoric Times: Natural plant resins, oils, and compounds were likely used by ancient peoples for medicinal, culinary, and ritualistic purposes.
• Ancient Civilizations: Civilizations such as the Egyptians and Greeks used aromatic oils and resins for incense, perfumes, and embalming. Notably, the use of myrrh and frankincense, which contain terpenes, were prevalent.

19th Century

• Isolation and Identification: The first half of the 19th century saw advances in organic chemistry. In the early 1800s, chemists began to isolate and identify individual components of essential oils. For example, terpenes like limonene (from citrus oils) were identified.
• Definition of Terpenes: In the mid-1800s, scientists began to classify compounds derived from essential oils. The term "terpene" was coined in 1866 by the German chemist August Friedrich Karl G. W. Schneider in reference to compounds derived from resin (derived from turpentine).

20th Century

• Structural Elucidation: The structure of terpenes was further elucidated during the 20th century with the development of advanced techniques such as chromatography and spectroscopy.
• Synthesis of Terpenes: The synthesis of terpenes, notably by chemists such as Otto Wallach, who won the Nobel Prize in Chemistry in 1910 for his work with terpenes and their derivatives, paved the way for synthetic terpene development.
• Biological Importance Discovery: Research in the mid-20th century began to reveal the biological roles of terpenes in plants, including their function in defense mechanisms, pollinator attraction, and ecological interactions.

Late 20th to Early 21st Century

• Industrial Applications: The late 20th century saw an increase in the use of terpenes in various industries, including food and beverage, cosmetics, and pharmaceuticals. Natural terpenes became popular in aromatherapy and wellness products.
• Biotechnological Advances: A more recent area of research has focused on the biosynthesis of terpenes in genetically modified plants and microbial systems, leading to sustainable production methods.
• Cannabis Research: In the 21st century, there has been an explosion of interest in terpenes in the context of cannabis, with researchers investigating the role of terpenes in the aroma, flavor, and therapeutic effects of cannabis strains.

Current Trends

Comparison of different methods of terpenes?

Terpenes are a diverse class of organic compounds produced by various plants, particularly conifers, and some insects. They play a significant role in the aroma and flavor profiles of many plants, and they are increasingly studied for their potential therapeutic properties. Here are some common methods for extracting or utilizing terpenes, along with a comparison of their effectiveness, efficiency, and other relevant factors.

1. Steam Distillation

• Method: Involves passing steam through plant material, causing the terpenes to evaporate. The steam is then cooled, and the terpenes are condensed and collected.
• Pros:
• Widely used and understood method.
• Good for larger quantities of plant material.
• Produces high-purity essential oils.
• Cons:
• Heat-sensitive terpenes may degrade.
• Requires specialized equipment.

2. Cold Press Extraction

• Method: Especially used for citrus fruits, this involves mechanically pressing the rind to release essential oils.
• Pros:
• No heat used, preserving the integrity of sensitive compounds.
• Simple and effective for citrus oils.
• Cons:
• Limited to specific types of plants (mainly citrus).
• Lower yield compared to distillation.

3. Solvent Extraction

• Can extract a variety of compounds.
• Cons:
• Similar degradation risks for heat-sensitive compounds as steam distillation.
• Longer extraction times can lead to lower yield.

Conclusion

The choice of extraction method for terpenes depends on various factors including the type of plant material, the desired quality and purity of the extract, cost considerations, and the intended use of the terpenes.

• For high-quality, delicate extracts, CO2 extraction is often considered the best option despite the higher cost.
• For citrus oils, cold pressing is ideal given the simplicity and effectiveness of the method.
• Steam distillation remains a versatile and widely used method, albeit with the potential risk of degrading sensitive compounds.

Ultimately, the best method varies based on the specific goals and constraints of the project at hand.
