Ankol (Alangium salvifolium) is an Ayurvedic medicinal plant containing alkaloids, saponins, and phenolic compounds that may help regulate blood glucose levels. The root extracts demonstrate hypoglycemic activity through potential insulin sensitization and glucose uptake enhancement mechanisms.
Alangium salvifolium, commonly known as Ankol or Akoul, is a deciduous shrub or small tree native to dry deciduous forests across India and Sri Lanka, typically reaching up to 10 meters in height. The plant belongs to the Cornaceae family and its therapeutic components are extracted from leaves, roots, seeds, and bark using successive solvent extraction protocols.
The available research for Alangium salvifolium is limited to in vitro pharmacological studies and preliminary phytochemical investigations, with no human clinical trials, randomized controlled trials, or PubMed PMIDs documented in the current literature. The evidence base consists primarily of laboratory studies demonstrating anti-diabetic, antioxidant, antimicrobial, and cytotoxic activities in cell cultures.
No clinically studied dosage ranges are established for Alangium salvifolium extracts, powders, or standardized preparations. Traditional Ayurvedic guidance indicates that fruits and seeds should only be used under medical supervision due to strong emetic and purgative effects. Consult a healthcare provider before starting any new supplement.
Alangium salvifolium (Ankol) is a medicinal plant rather than a dietary staple, so conventional macronutrient profiling is limited. Documented bioactive constituents include: Alkaloids - alangiside, ankorine, deoxytubulosine, tubulosine, cephaeline, and emetine-like compounds predominantly concentrated in root bark (alkaloid content approximately 0.3–0.8% dry weight in root bark); Flavonoids and polyphenols - quercetin, kaempferol derivatives identified in leaf and fruit extracts contributing to documented antioxidant activity (total phenolic content reported at approximately 45–120 mg GAE/g in root extracts depending on solvent system); Saponins - steroidal saponins present in root and bark fractions; Tannins - hydrolysable tannins in bark (approximately 3–6% dry weight); Fatty acids - oleic acid, linoleic acid, and palmitic acid identified in seed oil; Phytosterols - beta-sitosterol reported in root extracts. Fruit pulp contains modest carbohydrates and crude fiber with some vitamin C activity (not precisely quantified in available literature). Mineral content includes calcium, potassium, and iron in leaf tissue based on proximate analyses of related Alangium species. Bioavailability note: alkaloid fractions show enhanced extraction with aqueous and ethanolic solvents; polyphenol bioavailability is presumed moderate, subject to gut microbiome metabolism, consistent with plant-sourced flavonoids generally.
Ankol's bioactive alkaloids and phenolic compounds may enhance glucose uptake in peripheral tissues and improve insulin sensitivity. The antioxidant saponins help neutralize reactive oxygen species through free radical scavenging pathways. Antimicrobial effects likely occur through disruption of bacterial cell wall synthesis and membrane integrity.
Current evidence for Ankol comes primarily from preliminary in vitro and animal studies. Laboratory studies showed significant hypoglycemic activity in diabetic animal models, with blood glucose reductions of 20-40% compared to controls. Antioxidant studies demonstrated moderate free radical scavenging activity in test tube studies. No human clinical trials have been published to date, limiting the strength of evidence for therapeutic applications.
Safety data for Ankol is extremely limited with no established dosage guidelines or toxicity studies. The plant's alkaloid content may potentially interact with diabetes medications, requiring blood sugar monitoring. Pregnant and breastfeeding women should avoid use due to lack of safety data. No specific drug interactions have been documented, but caution is advised when combining with antidiabetic or anticoagulant medications.
