Levels of Kratom Alkaloid Mitragynine Were Likely Overestimated in Autopsies

A research article in the journal Drug Testing and Analysis uncovered a flaw in previous examinations of kratom’s main alkaloid, mitragynine. The study, lead by University of Florida pharmacutics researcher Dr. Abisheak Sharma, stated: There is a possibility that earlier reported studies did not separate the four mitragynine diastereomers, resulting in over‐quantification of mitragynine in …

13. Journal Club: How Kratom Alkaloids Act on Brain Receptors
/

We all know the mitragynine and 7-hydroxymitraginine act on the mu-opioid receptor. But for episode #13 of Journal Club we talk about a study that looks closely at the binding affinity of various kratom alkaloids on the plethora of opioid and adrenergic receptors in the brain. How exactly does this work? How do different alkaloids …

UF Researchers First to Grow Kratom for Published Study

In one of the first formal studies of its kind, if not the very first, a team from University of Florida cultivated 68 kratom trees and fertilized them at different rates, then measured for alkaloid content, chlorophyll, and total biomass. The study, “Effects of Nutrient Fertility on Growth and Alkaloidal Content in Mitragyna speciosa (Kratom)” …

Kratom and Alcoholism

Scientists have found evidence that kratom can help alleviate opioid withdrawal and cut down on cravings for recovering opiate addicts. Emerging research and experiential testimony indicates that kratom also cuts down on alcohol cravings and in some cases eliminates the desire to drink altogether. In a 2011 case study in European Psychiatry, researchers found “The …

What is speciofoline? The understudied kratom alkaloid

The most studied alkaloids of the 40 identified in kratom are mitragynine (MG) and 7-hydroxymitragynine (7-OH). Recently, a team of researchers studied speciofoline (C22H28N2O5), a kratom alkaloid present in less than 1% of alkaloids. They found that speciofoline does not bind to mu-opioid receptors (MOR) like MG and 7-OH. They also found unexpectedly that levels …
