Mitra-4. A Full Spectrum White & Green Vein Kratom Extract with 45% Mitragynine. 


HPLC Test results showing a minumum of 43%* Mitragynine can be provided showing individual production batches. We supply these certificates to our vendors and are available for anyone to see. This is a Full Spectrum Extract that is is made from White & Green vein leaf. The 5 main alkaloids, Mitragynine, Paynantheine, Speciogynine, Speciociliatine and 7-Hydroxymitragynine are still all present in the extract. The Fingerprint below which is also provided to our vendors shows the approximate percentage mix of the individual alkaloids in the alkaloid mix.  

Contains:  Approximately 430mg of Mitragynine per gm.

                         100mg extract is equivalent to approximately 4gm of leaf.             

43% Pure Mitragynine C23H30N2O4 with additional main alkaloids of Paynantheine, Speciogynine, Speciociliatine and a small amount of 7-Hydroxymitrgynine.

Due to its effects, Mitragynine is the main alkaloid that is targeted when Kratom leaf is extracted. In plain leaf Mitragynine naturally occurs at levels of about 1% by volume of the leaf. When Mitragynine of about 45% purity is isolated the 7-Hydroxymitragynine in the compound is completely lost and the other 3 main alkaloids Paynantheine, Speciogynine and Speciociliatine also start to disappear. Then at about 60% Mitragynine purity all the other main alkaloids are discarded and we are left with a pure isolated Mitragynine extract and only trace amounts of natural organic impurities.
