# Corynoline **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/corynoline **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-04-01 **Evidence Score:** 2 / 10 **Category:** Compound **Also Known As:** Corydalis alkaloid, Isoquinoline alkaloid from Corydalis, Corydalis bungeana alkaloid, Corydalis incisa extract compound ## Overview Corynoline is an isoquinoline alkaloid that primarily functions as an acetylcholinesterase inhibitor, affecting [neurotransmitter](/ingredients/condition/cognitive) [metabolism](/ingredients/condition/weight-management). This compound demonstrates potential sedative and [hepatoprotective](/ingredients/condition/detox) properties through modulation of cholinergic signaling pathways. ## Health Benefits • May inhibit cell adhesion, although evidence is based on preclinical studies. • Potential sedative effects, demonstrated in non-human studies. • Possible liver protection benefits, noted in laboratory settings. • Inhibits [acetylcholine](/ingredients/condition/cognitive)sterase, shown in in-vitro studies. • Forms reactive metabolites that conjugate with [glutathione](/ingredients/condition/detox), suggesting a detoxification role. ## Mechanism of Action Corynoline exerts its primary effects through [acetylcholine](/ingredients/condition/cognitive)sterase inhibition, preventing the breakdown of acetylcholine and enhancing cholinergic neurotransmission. The compound also interferes with cell adhesion mechanisms and forms reactive metabolites during hepatic processing. Its sedative properties likely involve GABAergic pathways, though specific receptor interactions require further investigation. ## Clinical Summary Current evidence for corynoline is limited to preclinical in-vitro and animal studies, with no human clinical trials available. Laboratory studies have demonstrated [acetylcholine](/ingredients/condition/cognitive)sterase inhibition activity, though specific IC50 values and dosage parameters have not been extensively characterized. Animal models suggest sedative effects and potential liver protection, but these findings have not been validated in human subjects. The formation of reactive metabolites raises questions about long-term safety that require clinical investigation. ## Nutritional Profile Corynoline is a pure isoquinoline alkaloid compound (molecular formula C21H21NO5, molecular weight 367.39 g/mol), not a whole food or nutritional ingredient, and therefore does not possess a conventional macronutrient or micronutrient profile. It contains no meaningful carbohydrates, proteins, fats, vitamins, or dietary minerals in any functional sense. As a bioactive compound, its relevant chemical characteristics include: a benzylisoquinoline alkaloid backbone with two methylenedioxy groups and one methoxy substituent, structurally classified within the protopine-type alkaloid family. It is isolated primarily from Corydalis bungeana and related Papaveraceae family plants, where it occurs at trace concentrations (typically <0.1% dry weight of plant material). Bioavailability data in humans is absent; preclinical data suggests moderate lipophilicity (estimated logP ~2.5–3.0), which supports membrane permeability but also indicates potential for metabolic activation by cytochrome P450 enzymes (particularly CYP3A4 and CYP2D6), generating reactive metabolites that are captured by [glutathione](/ingredients/condition/detox) conjugation, implying first-pass [metabolism](/ingredients/condition/weight-management) may limit systemic bioavailability. No fiber, protein, or mineral content is applicable. The compound's entire nutritional relevance is confined to its pharmacologically active alkaloid structure rather than any nutrient contribution. ## Dosage & Preparation No clinically studied dosage ranges are available as there are no human studies. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions The formation of reactive metabolites during corynoline [metabolism](/ingredients/condition/weight-management) raises potential concerns about hepatotoxicity with chronic use. No established safety profile exists for human consumption, and potential interactions with [acetylcholine](/ingredients/condition/cognitive)sterase inhibitor medications could lead to excessive cholinergic effects. Individuals with liver dysfunction should exercise particular caution due to metabolic concerns. Pregnancy and lactation safety data are unavailable, making use inadvisable for these populations. ## Scientific Research There are no human clinical trials, randomized controlled trials (RCTs), or meta-analyses available for corynoline. All reported pharmacological activities are based on preclinical studies without specific PMIDs. ## Historical & Cultural Context There are no documented historical or traditional medicinal uses of corynoline. It is derived from Corydalis bungeana, a known Chinese herb, but its use is confined to modern phytochemical isolation. ## Synergistic Combinations [Glutathione](/ingredients/condition/detox), Milk Thistle, Bacopa Monnieri, Ginkgo Biloba, Alpha-Lipoic Acid ## Frequently Asked Questions ### What does corynoline do to acetylcholinesterase? Corynoline inhibits acetylcholinesterase enzyme activity, preventing the breakdown of acetylcholine neurotransmitter. This inhibition enhances cholinergic signaling in neural pathways, though specific binding affinities have not been fully characterized in human studies. ### Is corynoline safe for liver health? While preclinical studies suggest potential liver protection benefits, corynoline forms reactive metabolites that could pose hepatotoxicity risks. No human safety data exists to confirm liver safety, making clinical evaluation necessary before therapeutic use. ### Can corynoline cause sedation? Animal studies indicate corynoline produces sedative effects, likely through GABAergic pathway modulation. However, optimal dosages, duration of effects, and safety margins have not been established in human trials. ### What type of alkaloid is corynoline? Corynoline belongs to the isoquinoline alkaloid class, characterized by its bicyclic aromatic structure containing nitrogen. This structural classification influences its pharmacological activity, particularly its interaction with cholinergic enzyme systems. ### Does corynoline interact with cholinesterase medications? Corynoline's acetylcholinesterase inhibition could potentially amplify effects of medications like donepezil or rivastigmine. Such interactions might cause excessive cholinergic stimulation, including nausea, muscle cramps, or bradycardia, though clinical interaction studies are lacking. ### What is the current state of clinical research evidence for corynoline in humans? Most evidence for corynoline comes from preclinical laboratory and animal studies, with limited clinical trials in human subjects. The available research demonstrates acetylcholinesterase inhibition and potential sedative effects primarily in non-human models, meaning efficacy and safety in humans remain largely unestablished. More rigorous human clinical trials are needed to determine whether corynoline's preclinical benefits translate to meaningful therapeutic applications. ### Who should avoid corynoline supplementation? Individuals with liver disease should exercise caution with corynoline due to its metabolic processing and formation of reactive metabolites, even though some evidence suggests potential liver protection. Pregnant and nursing women should avoid corynoline due to insufficient safety data in these populations. People taking acetylcholinesterase inhibitor medications or other central nervous system-active drugs should consult a healthcare provider before use. ### What natural food sources contain corynoline? Corynoline is an alkaloid compound found primarily in certain plant species, particularly in the genus Corydalis and related plants used in traditional medicine. However, corynoline is not present in significant quantities in common dietary foods, making supplementation the primary source for obtaining measurable amounts. The exact food sources and their corynoline concentrations are not well-documented in the scientific literature. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
