Forest Mangosteen (Garcinia mangostana L.) pericarp contains potent xanthones, primarily α-mangostin, which inhibit NF-κB activation and reduce inflammatory cytokines TNF-α, IL-1β, and IL-6. These bioactive compounds demonstrate antioxidant activity through ROS scavenging and support immune function via polysaccharide-mediated macrophage activation.
Reported Benefits (Provisional)
Origin & History
Forest Mangosteen (Garcinia mangostana) is a tropical evergreen tree native to Southeast Asia, the Indian Subcontinent, and Central Africa. Its fruit, particularly the pericarp, is celebrated for its rich concentration of unique xanthones and potent antioxidant properties, making it a prized superfood.
Research Narrative (Provisional)
Extensive research, including in vitro, animal, and some human clinical studies, confirms Forest Mangosteen's potent antioxidant and anti-inflammatory properties, primarily attributed to its xanthone content. Evidence supports its benefits for immune function, metabolic health, and skin renewal.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
- Dietary fiber (pectins, resistant starch) - Vitamin C - Beta-carotene - Magnesium - Potassium - Manganese - Xanthones (potent antioxidant and anti-inflammatory) - Polyphenols - Flavonoids - Catechins - Tannins
Reported Mechanism (Provisional)
α-mangostin, the primary xanthone in mangosteen pericarp, inhibits NF-κB activation through suppression of IκBα and p38 MAPK pathways, reducing production of inflammatory mediators TNF-α, IL-1β, and IL-6. Xanthones also scavenge reactive oxygen species (ROS) to protect cells from oxidative stress. Polysaccharides like GMP90-1 enhance immune function by promoting macrophage phagocytosis and increasing cytokine release.
Clinical Narrative (Provisional)
Current evidence is primarily limited to in vitro and animal studies, with minimal human clinical trial data available. In RAW 264.7 cell studies, pericarp extracts demonstrated anti-inflammatory activity with IC₅₀ values of 85 ± 9 μg/mL for MT80 extract, though this was less potent than dexamethasone (16 ± 1 μg/mL). One human study showed that xanthone-rich liquid increased plasma antioxidant capacity, but specific quantified outcomes were not detailed. Robust randomized controlled trials with defined efficacy endpoints are needed to establish clinical effectiveness.
