Triterpenes

Terpenoids & Volatile Oils

Triterpenes are a large group of naturally occurring plant compounds belonging to the broader terpenoid family. They are generally built from six isoprene units, creating a 30-carbon structure.

This group includes compounds such as ursolic acid, oleanolic acid, betulinic acid, lupeol, α-amyrin, β-amyrin and taraxasterol.

Unlike many smaller terpenes responsible for the aromas of herbs and flowers, most triterpenes are not highly volatile. They can occur throughout plants, including their leaves, roots, bark, fruits, flowers and protective surface waxes.

Triterpenes continue to receive scientific attention because of their biological activity and their presence in many edible, medicinal and traditionally used plants.

Potential Health & Wellness Interest

Research into triterpenes has explored several areas of health and wellness.

Inflammatory processes: Some triterpenes have demonstrated effects on pathways involved in inflammatory responses in laboratory research.

Antioxidant and cellular protection: Certain triterpenes are being investigated for their relationships with oxidative stress and cellular defence mechanisms.

Metabolic health: Research has explored possible relationships between certain triterpenes and glucose metabolism, lipid metabolism and other metabolic processes.

Liver health: Some triterpenes have demonstrated liver-protective activity in experimental research.

Cellular health: Triterpenes are also widely studied for their interactions with cellular signalling, cell growth and programmed cell death.

Microbial activity: Some have demonstrated antibacterial, antifungal or other antimicrobial activity under laboratory conditions.

Much of this research involves isolated compounds, concentrated extracts, laboratory experiments or animal studies. These findings do not mean that eating a plant containing triterpenes will produce the same effects.

Ontario Native Plants

Eastern Wintergreen — Gaultheria procumbens

A small evergreen woodland plant native to Ontario and other parts of eastern North America. Wintergreen grows close to the ground and retains its leaves through the colder months.

Bearberry — Arctostaphylos uva-ursi

A low-growing evergreen native to parts of Ontario and northern North America. Its ability to grow close to the ground makes it an interesting example of a native plant containing naturally occurring beneficial phytochemicals.

Staghorn Sumac — Rhus typhina

A familiar Ontario native recognized by its upright clusters of red fruit. Staghorn sumac has a long history of traditional use and provides another locally occurring example for exploring plant chemistry.

Common Plants That Can Be Grown Indoors Year-Round

Sweet Basil — Ocimum basilicum

Sweet basil is well suited to small-space growing and can be maintained indoors throughout the year with adequate lighting. Its fast growth also makes it useful for learning about growing fresh plants at home.

Holy Basil — Ocimum tenuiflorum

Also known as tulsi, holy basil can be grown in containers indoors with sufficient warmth and light. It provides another option for maintaining living herbs beyond Ontario's outdoor growing season.

Dandelion — Taraxacum officinale

Dandelion can be grown in containers or small indoor growing systems. The leaves and roots make it particularly interesting for exploring how different parts of the same plant can have different nutritional and phytochemical profiles.

Broadleaf Plantain — Plantago major

Broadleaf plantain is compact and adaptable, making it suitable for containers and small growing spaces. It is commonly found throughout Ontario and can also be intentionally cultivated indoors.

Narrowleaf Plantain — Plantago lanceolata

Narrowleaf plantain is another compact species suitable for container growing. Its narrow leaves require relatively little horizontal growing space.

True Lavender — Lavandula angustifolia

True lavender can be grown indoors with strong lighting, good airflow and suitable growing conditions. Beyond its familiar aromatic compounds, lavender contains a much broader range of plant chemicals.

Lavender 'Hidcote Blue Strain' — Lavandula angustifolia

A compact lavender cultivar that can be grown in containers. Its smaller growth habit can make it useful where indoor growing space is limited.

Lavender 'Dwarf Munstead' — Lavandula angustifolia

Another compact lavender cultivar suited to container growing. Its smaller size provides an option for people interested in growing lavender where larger plants may not be practical.

French Lavender — Lavandula stoechas

French lavender can be maintained in containers when provided with strong light, appropriate temperatures and well-draining growing conditions.

Tobacco — Nicotiana tabacum

Tobacco can be grown as a container plant, although it requires considerably more room than smaller herbs. It is included here strictly because of its phytochemistry and should not be interpreted as recommending smoking, consuming or otherwise using tobacco as a health product.

Growing in Small Spaces

An important part of understanding plant chemistry is discovering that interesting phytochemicals are not limited to expensive supplements or unusual plants.

Several plants in this profile—including basil, holy basil, dandelion, plantain and compact lavender varieties—can be grown in relatively small spaces. With sufficient lighting and suitable growing conditions, indoor growing can continue throughout the year instead of ending with Ontario's outdoor growing season.

Growing these plants does not provide a standardized or medicinal dose of triterpenes. The amount present can naturally change according to genetics, cultivar, plant part, maturity, lighting, nutrients, environmental conditions and harvest time.

Instead, growing plants provides another opportunity to learn about nutrition, plant diversity and the many compounds plants naturally produce.

A Bigger Picture of Health & Wellness

Triterpenes provide another example of why plants are much more complex than a simple list of vitamins and minerals.

A single plant can contain vitamins, minerals, polyphenols, flavonoids, carotenoids, terpenoids and many other compounds at the same time.

Understanding these individual compounds can help build a broader picture of plant chemistry, nutrition and health and wellness.

The purpose of the Wellness Profiles is not to turn individual compounds into miracle treatments. It is to provide accessible information that helps people learn more about plants, nutrition and the choices available to them.

The Wellness Profiles are provided for general educational and informational purposes only. They are not medical advice and are not intended to diagnose, treat, cure or prevent any disease or medical condition.

Research involving isolated triterpenes, concentrated plant extracts, laboratory experiments or animal studies does not establish that consuming a plant will produce the same effects.

The presence and concentration of plant compounds can vary according to species, cultivar, plant part, growing conditions, maturity, harvest time and preparation method. Never consume a plant unless it has been positively identified and is known to be safe for its intended use.

Some plants and concentrated plant products can cause adverse effects or interact with medications. Tobacco is included solely for phytochemical education and should not be interpreted as a recommended wellness source.

Anyone who is pregnant or breastfeeding, taking medications, managing a medical condition, or considering concentrated herbal preparations or supplements should consult an appropriate qualified healthcare professional.
