Major Alkaloids in Kratom

1. Mitragynine

Activity: Partial agonist at μ-opioid receptors; adrenergic and serotonergic interactions
Effects: Mood enhancement, energy support, general well-being
Unique Traits: Low abuse potential compared to opioids, structurally unrelated to classical opioids

Other Notable Alkaloids in Kratom

2. 7-Hydroxymitragynine

Role: 7-OH is a Minor metabolite in natural kratom leaf (<0.05%.
Activity: Potent μ-opioid receptor agonist
Effects: Stronger sedative and euphoric potential; contributes to controversy and regulation.
Note: Found in higher quantities in manipulated/ semi-synthetic extracted products like 7 oh.

3. Speciogynine

Role: One of the most abundant after mitragynine
Activity: Smooth muscle relaxant (non-opioid)
Effects: May contribute to muscle relaxation, calming effects

4. Paynantheine

Role: Second or third most abundant
Activity: Smooth muscle relaxant, antitussive properties
Effects: Thought to support the relaxing profile of certain strains

5. Speciociliatine

Role: Structural isomer of mitragynine
Activity: Weak μ-opioid receptor agonist
Effects: May contribute to mild mood-boosting effects

Additional Minor Alkaloids in Kratom (Less Studied, But Important)

6. Ajmalicine (Raubasine)

Role: Indole alkaloid
Activity: Alpha-1 adrenergic antagonist
Effects: Vasodilation, calming, potential nootropic benefits

7. Corynantheidine

Role: μ-opioid receptor antagonist (opposite of mitragynine)
Activity: Partial antagonist
Effects: Could balance some of kratom’s opioid-like actions

8. Isomitraphylline

Activity: Immunomodulatory in some studies
Effects: Under investigation for anti-inflammatory potential

9. Isopteropodine

Activity: Anti-microbial, weak CNS effects
Effects: May support immune defense

10. Mitraphylline

Activity: Anti-inflammatory, immunomodulating
Effects: May support overall body balance

11. Rhynchophylline

Activity: NMDA receptor antagonist, calcium channel blocker
Effects: Neuroprotective, possible cardiovascular effects

12. Tetrahydroalstonine

Activity: Hypoglycemic, anti-stress
Effects: May help regulate blood sugar and stress response

13. Akuammigine

Activity: Weak opioid receptor interaction
Effects: Analgesic-like actions in animal studies

14. Mitrafoline

Activity: Unknown
Effects: Still being studied

15. Mitragynine oxindole B (MOB)

Activity: Weakly active
Effects: Possibly contributes to the balance of effects

16. Mitraversine

Activity: Unknown
Effects: Not well understood

17. Stipulatine

Activity: Found in other Mitragyna species
Effects: Not well-studied in humans

18. Epicatechin

Role: Flavonoid, antioxidant
Activity: Not an alkaloid, but commonly present in kratom
Effects: Supports cardiovascular health, antioxidant protection
