Mitragyna speciosa Kratom alkaloid content varies quantitatively from geographical location, and from month to month, at different leaf harvest times, which has lead some teams (Shellard et al. in the 1970s) to conclude that there may be different geographical variants within the same species.

The Chelsea College Pharmacognosy Research Laboratories collected thirty samples of Kratom from Thailand, Malaysia, and Papua New Guinea between 1961 and 1970. All contained mitragynine, but also proved to have considerable variation in the alkaloid makeup. For red and green/ white leaved plants of Thailand, the most common alkaloidal profile was mitragynine, speciogynine, speciociliatine, paynantheine, traces of ajmalicine, traces of (C9) methoxy-oxindoles, and traces of other indoles.

Yet other Thai plants contained distinct alkaloidal profiles, some with many more alkaloids. In the Malay specimens, one contained mitragynine, speciofoline, and other indoles and oxindoles, while others contained mitragynine, ajmalicine, speciogynine, speciociliatine, paynantheine, traces of indoles, and (C9) methoxy-oxindoles. Specimens from Papua New Guinea contained mitragynine, speciogynine, speciociliatine, paynantheine, specionoxeine, and isospecionoxeine.

Prior to the late 1990’s, nearly all chemical studies of Kratom activity focused on mitragynine with the assumption thatmitragynine was the main active alkaloid. With 7-hydroxymitragynine now clearly identified out as the principal psychoactive alkaloid in Kratom, many elements of these studies need to be revised.

Takayama et al. also found that Thai and Malay Kratom had the alkaloids mitragynine, speciogynine, speciociliatine, paynantheine and 7-hydroxymitragynine in common. In both Thai and Malay samples, mitragynine was the most abundant alkaloid, yet it made up 66% of the total alkaloid in the Thai Kratom sample, while it made up only 12% of the alkaloids from the Malaysian sample. The Malay Kratom sample had mitragynaline and pinoresinol as major components, as well asmitralactonal, mitrasulgynine and 3,4,5,6-tetradehydromitragynine.
Working with the leaves of Malay Mitragyna Kratom plants, the Houghton and Said team found 4 new types of indole alkaloids (corynantheidaline, corynantheidalinic acid, mitragynaline and mitragynalinic acid), in very young leaves.

These new alkaloids were reported as having an unusual skeleton, with a carbon function at the C14 position (in comparison with previously known monoterpenoid indoles), but another research team, lead by Pr. Takayama, later revised the structure of the mitragynaline and corynantheidaline alkaloids, showing that there was actually no substitution on the 14 position.

The variety of alkaloids discovered in diverse Kratom samples to this day still calls for further studies and experimentation, investigating their specific activity, effects and potential applications.

Through its makeup and tradition of use, it is clear Mitragyna speciosa Kratom is much more than a simple opioid-like narcotic and mild stimulant. Many of the secondary chemicals found in Mitragyna speciosa Kratom are present in small yet appreciable quantities, and their synergetic role and activity in the general pharmacology of Mitragyna speciosa Kratom is not yet fully understood, as thorough research has only just begun.

    This is a great list, every couple months I always come back to this page to see the full list of alkaloids in kratom again.

    Does anybody knows what kind do u take for fibermyalgia

    1. Mitt Gynine

      Yea. You find a new doctor who’s willing to actually take the time to properly diagnose you. Fibro Myalgia is a fake “cop out” diagnosis used by lazy and/or unintelligent doctors. In the meanwhile, any strain of kratom will help you. I have a handful of auto immune type issues and have used kratom everyday for over 5+ years without issue. I was able to get off a 4 year opiate prescription with little to no withdrawl. Don’t fall for The strain hype. It’s more marketing and placebo than it is science. Good luck to you and get a stockpile before the criminal lobbyists at the FDA ban it .

      1. Kimber

        What kinds of kratom do you find best for opiates/opioid replacement?

      2. Connie

        Hi. I am very interested in finding the right kind to help with spinal injuries. Which causes nerve pain. I am not interested in the one blend which make u relaxed to a sleepy state. Can u recommend. My text #is. 717 623 1567. Any recommendation will be so appreciated. Thanks. Connie

        1. Nicky Jones

          Reds and greens can help u..also tumeric and black pepper.and agmatine sulfate help nerve pain.

    Can you link any sources of these facts? (not doubting, just would like to know where the information originated)

    1. Kratomlover

      Thata the definition of doubt if you need more resources to confirm your opinion

  5. chris s

    Awesome. Thank you. May I please have permission to use this information with your reference?

    Wow the the “PDR of Kratom”. The plant that saved my life and stopped me from taking from taking everything in my PDR. Still the best collection of alkaloid info. I hope we soon have the complete alkaloid profile comparison for every strain from every area at every time of the season and vendors will have access to very cheap testing and be required to list the primary alkaloids % OPIWANCANNIBI

    after a lifetime of depilating depression I functioning, working and have restarted a 10 year defunct businesss, my anxiety is at normal levels I have begun the first friendships I’ve had in many years this tree has given me a drug and alcohol free existence I actually feel happy most days ten years of therapy didn’t a achieve for me what 7 months of kratom has.

    1. ForeverASister

      Thank you! I myself have noticed a marked improvement, not far from saving my life. I am wondering if the medical profession is lying to us? I was on Zoloft for several years and still very depressed and debiliited, I trusted the doctors and I gained 50 lbs from the antidepresssant.
      My brother Alex, who is not alive, he told me about this plant. I lost him when he was 19years old, because of this stupid Drug War. I am alive today because this plant has changed my life, yet I can’t get my 19year old brother back. He was so severely depressed, and my parents told him not to use anything,and he died. I had to pull his breathing tubes out when he would not come back to us from his coma in the hospital. I don’t want this to happen to anyone. No one should die like this, no one.
      It seems to me that Doctors are taking an active role killing people, by lying to them about the therapies that can actually help them. My family still trusts doctors, yes, till death.

        So very sorry for your loss 😢

    Been looking for something like this for a long time! This is great.

  9. Jim

    Thanks for posting this information.

  10. Justin

    Thank you for the information and being responsible for all of the Kratom users and for the people who want to study up on this incredible natural herb that help’s so many people.

  11. Paul Kemp

    Thanks for a nice, clear write-up of the many alkaloids contained in this amazing herb. Much more study needs to be done to show how it produces the many stories of health recovery we are hearing in forums and chat groups on the Web.

    I have linked to this page to show my readers some of the advantages of kratom.
