What Is Mitragynine? The Alkaloid Behind Kratom

What is mitragynine? Molecular structure of kratom's main alkaloid

What is mitragynine? It is the principal alkaloid of the kratom plant — the compound that defines what kratom is commercially, chemically and legally. If you have seen “200 mg mitragynine” on a tablet label or a percentage on a certificate of analysis, this is the molecule those numbers count. Here is what it is, where it comes from, and why it is the industry’s reference compound.

The chemistry, briefly

Mitragynine (C23H30N2O4) is an indole alkaloid — structurally related to the family that includes yohimbine and, more distantly, compounds in the coffee plant, a botanical cousin of kratom. It was first isolated from Mitragyna speciosa leaves in the early 20th century, and it is the plant’s most abundant alkaloid by a wide margin. It is the reason the tree’s Latin name became the compound’s everyday shorthand.

How much mitragynine is in kratom leaf

Dried commercial leaf typically contains roughly 1–2% total alkaloids by weight, and mitragynine normally accounts for about half to two-thirds of that fraction. The exact figure varies with the tree’s genetics, the region, harvest maturity and drying protocol — which is precisely why lab-measured mitragynine content is the standard potency marker on every serious certificate of analysis. The variables behind those numbers are explored in how vein colors are made.

How mitragynine is measured

Labs quantify mitragynine with HPLC — high-performance liquid chromatography — which separates a sample’s compounds and measures each against certified reference standards. That is the method behind every COA potency panel, and the reason a milligram claim like ours can be independently verified batch by batch. Learn the full document in how to read a kratom COA.

Standardized mitragynine products

Raw leaf gives you whatever mitragynine the harvest delivered. Our mitragynine tablets do the opposite: extract and standardize the alkaloid, then compress it to an exact stated strength — 200 mg per tablet — so every serving is identical. The buyer logic of that choice is laid out in mitragynine tablets vs kratom powder.

What mitragynine is not

  • It is not the only alkaloid. Dozens of others ride along in raw leaf — the full cast in kratom alkaloids 101, including the trace but consequential 7-hydroxymitragynine.
  • It is not a medicine. The FDA has approved nothing kratom-derived; no claim on this site suggests otherwise.
  • It is not risk-free. Like every active compound, it demands adult-only use, label servings and respect for tolerance — safety basics.
