7-Hydroxymitragynine (7-OH) is a terpenoid indole alkaloid from the plant Mitragyna speciosa, commonly known as kratom. [2] It was first described in 1994 [3] and is a human metabolite metabolized from mitragynine present in the Mitragyna speciosa. 7-OH binds to opioid receptors like mitragynine, but research suggests that 7-OH binds with greater efficacy.
The solubility of mitragynine from kratom in neutral-pH and alkaline water is very low (0.0187 mg/ml at pH 9). [20] The solubility of mitragynine in acidic water is higher (3.5 mg/ml at pH 4), however, this alkaloid can become unstable, so certain products, such as low-pH beverages, have a very short shelf life. [20]
Mitragynine pseudoindoxyl is a rearrangement product of 7-hydroxymitragynine, an active metabolite of mitragynine. [ 1 ] Mitragynine pseudoindoxyl can be produced in the blood as a metabolite of 7-hydroxymitragynine.

[32] [11] [9] The alkaloids mitragynine and 7-hydroxymitragynine are responsible for many of the complex effects of kratom, [11] [9] but other alkaloids may also contribute synergistically. [32] The effects of both mitragynine and 7-HMG remain disputed despite substantial study. Both are partial agonists of the μ-opioid receptor.
