Mitraphylline is an oxindole alkaloid, made mostly of carbon, hydrogen, nitrogen, and oxygen. It’s found in kratom at trace amounts (less than 1% of the total alkaloid makeup of kratom leaf). Cat’s Claw contains much more of the alkaloid: 1 gram of dried cat’s claw bark might contain 0.5 to 3 milligrams of mitraphylline. Research …

Scientists from British Columbia Institute of Technology and University of Illinois published a study that examines five 7-hydroxymitragynine (the abbreviation 7-OH has become popularized, but the scientists use 7-HMG in this study) products marketed as “kratom extracts”. A kratom extract is a concentrated form of the kratom plant made by extracting its active alkaloids, of …

A new study published in Frontiers in Plant Science is presenting a clearer picture of how post-harvest processing changes the plant’s chemistry. The researchers from University of Florida and Oregon State University compared kratom varieties grown in Hawaii and Malaysia to see how factors like withering time, drying temperature, and harvest season influence alkaloid profiles—particularly …
