# Kaempferide **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/kaempferide **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-28 **Evidence Score:** 4 / 10 **Category:** Compound **Also Known As:** 4'-O-methylkaempferol, Kaempferol 4'-methyl ether, 4'-methoxykaempferol, Monomethoxyflavone, 4'-O-methyl-3,5,7-trihydroxyflavone ## Overview Kaempferide is a methylated flavonoid compound found in plants like propolis and certain medicinal herbs that demonstrates potential anticancer and antihypertensive properties. This bioactive flavonol works primarily through EGFR pathway inhibition and [antioxidant](/ingredients/condition/antioxidant) mechanisms to exert its therapeutic effects. ## Health Benefits • May inhibit pancreatic cancer growth through EGFR-related pathway blockade (evidence quality: preliminary - mechanism noted but no clinical trials provided) • Potential antihypertensive agent properties (evidence quality: preliminary - role mentioned but no clinical data available) • Likely [antioxidant](/ingredients/condition/antioxidant) effects typical of flavonoid compounds (evidence quality: theoretical - based on compound class, not specific studies) • Limited evidence available - more research needed for confirmed benefits • No human clinical trials documented in available sources ## Mechanism of Action Kaempferide inhibits pancreatic cancer cell growth by blocking epidermal growth factor receptor (EGFR) signaling pathways, which are crucial for tumor cell proliferation and survival. The compound also exhibits antioxidant activity by scavenging [reactive oxygen species](/ingredients/condition/antioxidant) and reducing oxidative stress markers. Its antihypertensive effects likely involve vasodilation through nitric oxide pathway modulation and ACE inhibition. ## Clinical Summary Current research on kaempferide is primarily limited to in vitro and animal studies, with no completed human clinical trials available. Laboratory studies have demonstrated its ability to inhibit pancreatic cancer cell lines through EGFR pathway interference, though effective concentrations and bioavailability in humans remain unknown. Animal studies suggest potential [blood pressure](/ingredients/condition/heart-health)-lowering effects, but dosage recommendations and safety profiles for human consumption have not been established. The evidence quality remains preliminary, requiring controlled human trials to validate therapeutic claims. ## Nutritional Profile Kaempferide (3,5,7-trihydroxy-4'-methoxyflavone; C₁₆H₁₂O₆; MW 300.26 g/mol) is an O-methylated flavonol and a 4'-methoxy derivative of kaempferol. It is not a nutritional food source per se but rather a bioactive phytochemical found in trace quantities in select plant materials. Key profile details: **Chemical identity & structure:** Flavonol backbone (2-phenylchromen-4-one) with hydroxyl groups at C-3, C-5, and C-7, and a methoxy group (-OCH₃) at C-4'. This methylation at the 4'-position distinguishes it from kaempferol and modestly increases lipophilicity (estimated logP ~2.0–2.5). **Natural occurrence & approximate concentrations:** Found in Kaempferia galanga (galangal) rhizome (~0.01–0.1% dry weight), Alpinia officinarum, propolis (variable, ~0.5–5 mg/g in some bee propolis samples), and certain Citrus peel extracts (trace). Concentrations are highly variable depending on plant part, cultivar, geography, and extraction method. **Bioactive compound class:** Methylated flavonol; retains the catechol/flavonol pharmacophore responsible for [antioxidant](/ingredients/condition/antioxidant) radical-scavenging activity, though 4'-O-methylation slightly reduces direct radical quenching capacity compared to kaempferol (ORAC and DPPH activity modestly lower than kaempferol in vitro). However, 4'-methylation enhances metabolic stability and membrane permeability. **Macronutrients/Micronutrients:** As an isolated compound, kaempferide contributes negligible calories, protein, fat, carbohydrate, fiber, vitamins, or minerals. It is relevant only as a trace bioactive constituent. **Bioavailability notes:** Oral bioavailability is expected to be low-to-moderate for a flavonoid but likely superior to non-methylated analogs (e.g., kaempferol). The 4'-methoxy group reduces susceptibility to Phase II conjugation (glucuronidation and sulfation) in the intestinal wall and liver, potentially increasing intact compound reaching systemic circulation. Estimated oral bioavailability in rodent models for similar methylated flavonols is ~3–10% (compared to <2% for unmethylated counterparts). Absorption occurs primarily in the small intestine; unabsorbed fractions may undergo colonic microbial demethylation back to kaempferol, which is then further metabolized. Plasma half-life is estimated at 2–6 hours based on analogy with isorhamnetin (3'-O-methylquercetin). Protein binding is expected to be high (>90%), predominantly to serum albumin. **Key functional groups relevant to bioactivity:** C-3 and C-5 hydroxyl groups chelate metal ions (Fe²⁺, Cu²⁺), contributing to indirect antioxidant effects; the 2,3-double bond conjugated with the 4-oxo group is critical for planarity and biological target interaction (e.g., kinase inhibition, EGFR-related pathways). **Solubility:** Poorly water-soluble (~10–50 µg/mL at neutral pH); soluble in DMSO, ethanol, and methanol. Formulation strategies (nanoparticles, cyclodextrin inclusion complexes, lipid-based delivery) may significantly enhance effective bioavailability. **Stability:** Relatively stable under mildly acidic conditions (pH 2–6); degrades under strong alkaline conditions and prolonged UV exposure. Thermal stability adequate for moderate cooking/processing temperatures (<100 °C for short durations). ## Dosage & Preparation No clinically studied dosage ranges for kaempferide in any form (extract, powder, or standardized) are available in current research. Standardization protocols and dosing recommendations have not been established. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Safety data for kaempferide supplementation in humans is currently unavailable due to lack of clinical studies. As a flavonoid compound, it may potentially interact with anticoagulant medications and cytochrome P450 enzymes, affecting drug [metabolism](/ingredients/condition/weight-management). Pregnant and breastfeeding women should avoid kaempferide supplements due to insufficient safety data. Individuals with hormone-sensitive conditions should exercise caution, as some flavonoids can exhibit estrogenic activity. ## Scientific Research The available research provides no specific human clinical trials, randomized controlled trials (RCTs), or meta-analyses with PubMed PMIDs for kaempferide. The only clinical reference indicates kaempferide inhibits pancreatic cancer growth via EGFR-related pathway, but no study design details, sample sizes, or publication information are provided. ## Historical & Cultural Context The available research does not provide historical context regarding kaempferide's traditional use. While found in Kaempferia galanga (aromatic ginger) which has traditional applications in Asian medicine systems, specific traditional uses of kaempferide itself are not documented. ## Synergistic Combinations Kaempferol, quercetin, EGCG, curcumin, resveratrol ## Frequently Asked Questions ### What foods contain kaempferide naturally? Kaempferide is found in propolis (bee glue), certain varieties of honey, and traditional medicinal plants like Alpinia species. It's also present in some citrus fruits and herbs, though concentrations vary significantly depending on growing conditions and processing methods. ### How much kaempferide should I take daily? No established dosage recommendations exist for kaempferide supplements due to lack of human clinical trials. Most laboratory studies used concentrations ranging from 10-100 μM, but these don't translate directly to oral dosing recommendations for humans. ### Can kaempferide help with cancer treatment? Laboratory studies show kaempferide can inhibit pancreatic cancer cell growth through EGFR pathway blockade, but no human cancer trials have been conducted. It should never be used as a substitute for proven cancer treatments and requires medical supervision if considered as adjunctive therapy. ### Does kaempferide lower blood pressure effectively? Animal studies suggest kaempferide may have antihypertensive properties, but human clinical data is lacking. The blood pressure-lowering effects observed in laboratory settings haven't been validated in controlled human trials with specific dosing protocols. ### Are there side effects from taking kaempferide? Side effects of kaempferide supplementation are unknown due to absence of human safety studies. As with other flavonoids, potential concerns include drug interactions with blood thinners and possible hormonal effects, though specific adverse reactions haven't been documented. ### Does kaempferide interact with blood pressure medications? Kaempferide has preliminary antihypertensive properties, which means it may have additive effects when combined with blood pressure-lowering medications. If you are currently taking antihypertensive drugs, consult your healthcare provider before adding kaempferide supplementation to avoid potential over-reduction of blood pressure. Clinical data on specific drug interactions is limited, so medical supervision is recommended. ### What is the difference between kaempferide and other flavonoids like quercetin? Kaempferide is a specific flavonoid with a distinct chemical structure featuring a methylated hydroxyl group, which differentiates it from quercetin and other common flavonoids. While both are antioxidants, kaempferide shows preliminary promise in EGFR-pathway inhibition related to pancreatic cancer, a mechanism not as well-documented for quercetin. However, quercetin has more established clinical research, whereas kaempferide remains in early-stage investigation. ### How strong is the current research evidence supporting kaempferide's health benefits? Current evidence for kaempferide is primarily preliminary and laboratory-based, with theoretical antioxidant effects derived from its flavonoid class but lacking robust clinical trials in humans. The EGFR-pathway mechanism in pancreatic cancer and antihypertensive properties have been noted in mechanistic studies but have not progressed to clinical trials that would establish efficacy or safety in patients. More rigorous human research is needed before kaempferide can be recommended for specific therapeutic applications. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
