Origin & History
Natural habitat
Umbelliferone (7-hydroxycoumarin) is a naturally occurring phenolic compound found in various plants including fennel, carrot, celery, noni fruit, and Hydrangea species. It appears as a white to gray-brown crystalline solid and is typically extracted using solvent methods like acetone from plant roots, rhizomes, or fruits.
“Umbelliferone-containing plants have been used for over 2000 years in Ayurveda and Unani medicine for digestion and inflammation, while Traditional Chinese Medicine employed Cnidium and Hydrangea for detoxification and women's health. The compound itself was first identified structurally in 1842, though isolated umbelliferone was not traditionally used.”Traditional Medicine
Scientific Research
Clinical evidence for isolated umbelliferone is extremely limited. Only one Phase I pharmacokinetic study (n=12) tested 250 mg oral doses for sulfotransferase activity (PMID: 16424369). A small RCT on noni juice containing trace amounts of umbelliferone (n=40 smokers) showed reduced DNA adducts after 1 month (PMID: 16506860), but effects cannot be attributed to umbelliferone alone.
Preparation & Dosage
Traditional preparation
No established therapeutic dosages due to lack of clinical trials. Pharmacokinetic study used 250 mg single oral dose. Commercial supplements contain 10-50 mg/day umbelliferone equivalents, but these are unstudied. In food sources: noni juice provides ~0.75-7.5 mg/day from 750 mL. Consult a healthcare provider before starting any new supplement.
Nutritional Profile
Umbelliferone (7-hydroxycoumarin) is a pure phytochemical compound, not a whole food, and therefore contains no macronutrients (0g protein, 0g fat, 0g carbohydrates), no dietary fiber, vitamins, or minerals in isolated form. Molecular weight: 162.14 g/mol. Classified as a hydroxylated coumarin (benzopyrone derivative) and a member of the phenylpropanoid biosynthetic family. Naturally occurring in plants of the Apiaceae/Umbelliferae family including carrots, coriander, fennel, and parsley, typically at concentrations of 0.01–0.5 mg/g dry weight depending on plant source. Also found in noni juice (Morinda citrifolia) as a minor constituent. As a bioactive compound, its primary relevance is pharmacological rather than nutritional: it exhibits UV-absorbing properties (absorption maximum ~325 nm), acts as a fluorescent marker at physiological pH, and functions as a precursor to other hydroxycoumarins. Bioavailability data in humans is limited; in vitro and animal studies suggest moderate intestinal absorption due to its relatively small, lipophilic structure (LogP ~1.24), with hepatic glucuronidation and sulfation as primary Phase II metabolic pathways. In context of dietary sources (e.g., noni juice trial referenced), intake levels are far below pharmacologically active concentrations (IC50 50–100 μM) demonstrated in cell studies, meaning isolated compound concentrations studied in vitro are not achievable through normal dietary consumption.
How It Works
Mechanism of Action
Umbelliferone acts as a potent antioxidant by scavenging reactive oxygen species (ROS) through its hydroxyl group at the 7-position of the coumarin backbone, thereby reducing oxidative stress-induced DNA damage. It modulates apoptosis in cancer cells by upregulating pro-apoptotic proteins such as Bax and downregulating anti-apoptotic Bcl-2, triggering caspase-3 activation. Additionally, umbelliferone inhibits cyclooxygenase (COX) enzymes and suppresses NF-κB signaling, contributing to its proposed anti-inflammatory and antimicrobial effects.
Clinical Evidence
The most direct human evidence comes from a single randomized controlled trial (n=40) examining noni juice containing umbelliferone among cigarette smokers, which reported reduced urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG), a biomarker of oxidative DNA damage, though umbelliferone was not isolated as the sole active compound. No clinical trials have evaluated isolated umbelliferone supplementation in humans, making it impossible to attribute specific dosage-response relationships. Antimicrobial activity against gram-positive bacteria (including Staphylococcus aureus) and Candida species has been demonstrated in multiple in vitro studies, with minimum inhibitory concentrations (MICs) in the range of 64–256 µg/mL. Anticancer effects, including apoptosis induction in hepatocellular and breast cancer cell lines, are documented exclusively in in vitro and rodent models, representing early-stage preclinical evidence only.
Safety & Interactions
Umbelliferone has not been evaluated for safety in dedicated human clinical trials, so formal tolerability data are lacking. As a coumarin derivative, it may potentiate the anticoagulant effects of warfarin and other vitamin K antagonists by competing with coumarin metabolism via CYP2A6 and CYP1A2 hepatic enzymes, warranting caution in patients on blood thinners. High-dose coumarins have historically been associated with hepatotoxicity in animal studies, though umbelliferone specifically has not been linked to liver injury in available literature. Pregnant or breastfeeding individuals should avoid supplemental umbelliferone due to the complete absence of safety data in these populations.

Frequently Asked Questions
What foods are naturally high in umbelliferone?
Umbelliferone is found predominantly in plants of the Apiaceae family, including carrots (Daucus carota), parsley (Petroselinum crispum), coriander (Coriandrum sativum), and angelica root. It is also present in Rutaceae family plants such as bergamot and certain citrus peels, and has been identified as a constituent in noni juice (Morinda citrifolia). Typical dietary intake from these foods is low and far below concentrations used in in vitro studies.
Can umbelliferone help prevent cancer?
Current evidence for umbelliferone's anticancer effects is limited to in vitro cell culture studies and animal models, where it has induced apoptosis in hepatocellular carcinoma, breast cancer (MCF-7), and colon cancer cell lines via Bax/Bcl-2 modulation and caspase-3 activation. No human clinical trials have tested umbelliferone as a cancer preventive or treatment agent. It would be premature and inaccurate to claim it prevents or treats cancer in humans based on existing data.
Does umbelliferone interact with blood thinners like warfarin?
Umbelliferone is a hydroxylated coumarin, and coumarin-class compounds are known to be metabolized by CYP2A6 and can influence coumarin anticoagulant metabolism, raising a theoretical interaction risk with warfarin (Coumadin) and similar drugs. This interaction has not been confirmed in human pharmacokinetic studies for umbelliferone specifically, but the structural similarity to anticoagulant coumarins means caution is warranted. Anyone taking anticoagulant therapy should consult a physician before using any umbelliferone-containing supplement.
What is the difference between umbelliferone and other coumarins like coumarin or esculetin?
Umbelliferone (7-hydroxycoumarin) differs from parent coumarin by the addition of a hydroxyl group at the 7-position, which significantly enhances its antioxidant and antimicrobial activity compared to unsubstituted coumarin. Esculetin (6,7-dihydroxycoumarin) carries an additional hydroxyl group at position 6, giving it stronger chelating capacity but a slightly different receptor and enzyme interaction profile. These structural differences translate to distinct pharmacological activities and metabolic fates, with umbelliferone being a known metabolite of herniarin and a precursor to scopoletin through further hydroxylation.
Is there a recommended dosage for umbelliferone supplements?
There is currently no established or clinically validated dosage for umbelliferone supplementation in humans, as no isolated human dose-finding trials have been conducted. Doses used in rodent studies typically range from 10 to 50 mg/kg body weight, which does not directly translate to a safe or effective human equivalent without clinical validation. Until human trials establish safety and efficacy thresholds, no specific dosage recommendation can responsibly be made.
What does the research evidence show about umbelliferone's antioxidant effectiveness?
Umbelliferone demonstrates antioxidant activity in laboratory studies through DPPH radical scavenging mechanisms, though most evidence is limited to in vitro (test tube) research rather than human trials. While these preliminary findings are promising, the current body of clinical research on umbelliferone's antioxidant effects in humans remains limited, making it difficult to establish definitive efficacy claims. More human studies would be needed to determine whether laboratory antioxidant activity translates to meaningful health benefits in supplement form.
Is umbelliferone safe for use during pregnancy or breastfeeding?
There is insufficient safety data on umbelliferone supplementation during pregnancy and breastfeeding, so use during these periods should be avoided unless specifically recommended by a healthcare provider. As a coumarin-type compound, caution is warranted given the known teratogenic effects of some related coumarins; however, umbelliferone's specific safety profile in pregnant or nursing women has not been adequately studied. Pregnant and breastfeeding individuals should consult their healthcare provider before using umbelliferone supplements.
Does umbelliferone have any antimicrobial applications, and is the evidence strong enough for supplementation?
In vitro studies show umbelliferone possesses potential antimicrobial activity against bacteria and fungi, but all current evidence comes from laboratory settings rather than human clinical trials. This means the antimicrobial effects observed in test tubes may not translate to therapeutic benefit when taken as a supplement in the human body. Until clinical research in humans is conducted, antimicrobial claims for umbelliferone supplementation remain speculative and should not be relied upon for treating infections.
