Walk through any functional botanical aisle — physical or digital — and you will eventually encounter three names on labels, lab reports, and product descriptions: mitragynine, kavalactones, and mesembrine. Each belongs to a different plant, a different tradition, and a different modern product category.
This article offers a science-lite introduction to these compounds — what they are, which plants they come from, and how they appear on certificates of analysis. Pair it with our 250 Facts pillar guide.
This is educational content only. It does not claim that kratom, kava, or kanna diagnose, treat, cure, or prevent any disease or condition. It is not medical advice.
Three Plants, Three Compound Families
| Plant | Botanical name | Region | Compound family commonly discussed |
|---|---|---|---|
| Kratom | Mitragyna speciosa | Southeast Asia | Mitragynine-type alkaloids |
| Kava | Piper methysticum | Pacific Islands | Kavalactones |
| Kanna | Sceletium tortuosum | Southern Africa | Mesembrine-type alkaloids |
These compounds are often referenced because they help identify plant material, appear on lab reports, and give buyers a framework for reading product labels. Discussing a compound is not the same as making a health claim about it.
Mitragynine: Kratom's Most Discussed Alkaloid
Mitragynine is an indole alkaloid found in the leaves of Mitragyna speciosa, the tree commonly known as kratom. In research literature, mitragynine is frequently described as the most abundant alkaloid in kratom leaf material, though exact proportions vary by strain, region, harvest timing, and processing method.
Why mitragynine appears on COAs
Kratom certificates of analysis commonly report mitragynine content as a percentage of dry weight or in milligrams per gram. This serves several practical purposes:
- Identity confirmation — Results consistent with kratom leaf help verify the material tested
- Batch consistency — Buyers and retailers can compare results across production runs
- Label transparency — Some products reference alkaloid content on packaging
Mitragynine is widely discussed in botanical and pharmacological literature. That discussion reflects research interest — not an endorsement of any medical use.
7-Hydroxymitragynine (7-OH): Important Context
7-hydroxymitragynine, often shortened to 7-OH, is another alkaloid associated with kratom. It occurs naturally in kratom leaf in trace amounts — far less abundant than mitragynine in traditional leaf products.
Critical framing: Products with added or enhanced 7-OH levels are a separate regulatory and safety concern and should not be positioned the same way as traditional kratom leaf products. The FDA has issued consumer updates specifically addressing products marketed with elevated 7-OH content, noting distinct safety and regulatory considerations compared to conventional kratom leaf.
When you see 7-OH on a COA for a traditional leaf product, read it as a naturally occurring trace compound — not as a benchmark for comparing all kratom products. Enhanced 7-OH formulations belong in a separate conversation entirely.

Kavalactones: Kava's Identity Markers
Kavalactones are a group of lactone compounds found in the root of Piper methysticum, the plant known as kava. Unlike kratom's alkaloid profile, kava is defined by this lactone group — and different kavalactones are often identified by a six-letter chemotype code (such as kavain, dihydrokavain, methysticin, and others).
Why kavalactones matter for product labels
Kavalactone content is commonly referenced on kava product labels and in traditional preparation discussions. In modern ready-to-drink formats — kava seltzers, shots, and capsules — kavalactone totals or individual lactone profiles may appear on packaging.
Kavalactones help characterize kava products by composition. They are not a substitute for quality testing, responsible sourcing, or adherence to product labels.
Traditional and modern context
Kava has a long history of traditional preparation in Pacific Island cultures, where the root was processed into beverages for social and ceremonial contexts. Modern kava products range from traditional-style powders to carbonated seltzers and concentrated shots available through collections like Kanna & Kava and Seltzers.
The National Center for Complementary and Integrative Health (NCCIH) notes that kava has been traditionally used in social and cultural settings and that research on kava continues. Consumers should be aware of safety considerations discussed in NIH resources, including liver-related advisories associated with some kava products and preparations.
Mesembrine: Kanna's Alkaloid Profile
Mesembrine is an alkaloid associated with Sceletium tortuosum, commonly known as kanna. It belongs to a broader group of mesembrine-type alkaloids found in the plant, which has a history of traditional use in Southern Africa.
Kanna in modern products
Kanna appears in several modern formats — capsules, gummies, beverages, and blended functional products. Mesembrine and related alkaloids may be referenced on labels or in product descriptions, though testing and labeling practices vary across the category.
Kanna is distinct from both kratom and kava in plant identity, geography, and compound profile. For a comparison, see our guides on kanna vs kava and kanna drinks and supplements.
Research literature discusses mesembrine-type alkaloids in the context of plant chemistry. That research interest does not translate into approved medical uses or treatment claims.
How Compounds Appear on COAs
Laboratory testing is where compound names move from product marketing to documented results. Here is how each compound family typically shows up:
On kratom COAs
- Mitragynine — Reported as a primary alkaloid, usually with percentage or mg/g values
- 7-OH — May appear in expanded alkaloid panels; interpret as trace natural occurrence in leaf products
- Additional alkaloids (speciociliatine, paynantheine, and others) may appear in comprehensive panels
On kava COAs
- Total kavalactones — Sometimes reported as a combined percentage
- Individual lactones — Kavain, dihydrokavain, methysticin, dihydromethysticin, yangonin, and desmethoxyyangonin in detailed panels
- Contaminant and microbiology results alongside lactone profiles
On kanna COAs
- Mesembrine and related alkaloids — When tested, reported according to the lab's available methods
- Practices vary more in this emerging category; ask suppliers about specific panels

Comparing Compounds Without Confusing Plants
A common mistake among new botanical buyers is conflating compound names across plants. Keep these distinctions clear:
- Mitragynine belongs to kratom — not kava or kanna
- Kavalactones belong to kava — not kratom or kanna
- Mesembrine belongs to kanna — not kratom or kava
Product formats, traditions, and regulatory contexts differ for each plant. A compound name on a label tells you about plant chemistry — not about interchangeability between products.
Responsible Use Reminder
Botanical products may not be appropriate for everyone. Adults should follow product labels and verify that products are permitted where they live. Kratom legality varies by state and locality.
Botanicals may interact with medications, alcohol, or other substances. Pregnant or nursing individuals and those with medical conditions should consult a qualified professional before using kratom, kava, kanna, or any botanical product.
FAQ
Is mitragynine the same as kratom?
Mitragynine is a compound found in kratom leaf. It is not the entire plant — kratom contains many alkaloids and other constituents beyond mitragynine alone.
What are kavalactones in simple terms?
Kavalactones are a group of naturally occurring compounds in kava root. They are commonly used to characterize kava products and appear on some labels and lab reports.
What is mesembrine?
Mesembrine is an alkaloid associated with kanna (Sceletium tortuosum). It is part of a broader group of alkaloids found in the plant.
Does higher mitragynine mean better quality?
Not necessarily. Alkaloid content is one data point on a COA. Quality also depends on contaminant testing, sourcing, processing, and batch consistency — not alkaloid percentage alone.
Why does the FDA discuss 7-OH separately?
The FDA has issued consumer updates about products with added or enhanced 7-OH levels, noting they raise distinct regulatory and safety concerns compared to traditional kratom leaf products where 7-OH occurs naturally in trace amounts.
Do all three compounds appear on every COA?
No. Testing panels vary by plant, product type, and laboratory. Kratom COAs most commonly include mitragynine. Kava COAs focus on kavalactones. Kanna testing practices are less standardized across the market.
