Infobox references

7-Hydroxymitragynine is a terpenoid indole alkaloid from the plant Mitragyna speciosa, commonly known as Kratom.[2] It is often referred to as ‘7-OH’. It was first described in 1994[3] and is a natural product derived from the mitragynine present in the Kratom leaf. It is considered an oxidized derivative and active metabolite of mitragynine.[4]

## Metabolism

After a kratom study, it was revealed that 7-OH converts into Mitragynine pseudoindoxyl.[5]
