Cornus officinalis (Cornelian cherry) is a Traditional Chinese Medicine herb containing iridoid compounds like loganin and loganic acid. It traditionally supports liver and kidney function while providing antioxidant effects through these bioactive compounds.
Cornus officinalis (Cornelian Cherry, Shan Zhu Yu) is a deciduous shrub native to East Asia, particularly China, Korea, and Japan, belonging to the Cornaceae family. The bioactive compounds are extracted from ripe drupes using traditional water decoction or modern solvent extraction with methanol or ethanol. The fruit contains primarily iridoids, anthocyanins, and phenolic acids.
No human clinical trials, RCTs, or meta-analyses for Cornus officinalis were identified in the research. Available data focuses solely on phytochemical composition and traditional use patterns. Human efficacy data for conditions like diabetes or inflammation is absent.
No clinically studied dosage ranges are available for Cornus officinalis extracts, powders, or standardized forms. Traditional preparations use fruit decoctions, but specific standardization parameters and quantified doses from trials are not reported. Consult a healthcare provider before starting any new supplement.
Cornus officinalis fruit (Shan Zhu Yu) is primarily used as a medicinal herb rather than a dietary staple, so nutritional data reflects its phytochemical profile more than macronutrient content. **Bioactive Compounds:** Rich in iridoid glycosides, primarily loganin (~0.5–1.5% dry weight), morroniside (~0.3–1.2% dry weight), and loganic acid (~0.1–0.5% dry weight), which are considered the principal pharmacologically active constituents. Contains significant levels of cornuside, sweroside, and 7-O-methylmorroniside as secondary iridoids. **Organic Acids:** High in malic acid, tartaric acid, and ursolic acid (~0.3–0.8% dry weight); gallic acid and ellagic acid also present. **Polyphenolics & Tannins:** Total tannin content approximately 5–8% dry weight, including hydrolyzable tannins (tellimagrandin I and II, isoterchebin, cornusiin A–F); total polyphenol content approximately 3–7% dry weight depending on extraction and origin. **Anthocyanins:** Contains cyanidin-3-O-glucoside and pelargonidin-3-O-glucoside, contributing to the red pigmentation of ripe fruit; total anthocyanin content approximately 50–200 mg/100 g fresh weight. **Polysaccharides:** Cornus officinalis polysaccharides (COP) constitute approximately 5–10% of dried fruit and have been studied for immunomodulatory potential. **Triterpenoids:** Ursolic acid and oleanolic acid present at ~0.2–0.5% dry weight. **Minerals:** Contains calcium (~100–200 mg/100 g dry weight), potassium (~500–800 mg/100 g dry weight), magnesium (~50–100 mg/100 g dry weight), iron (~2–5 mg/100 g dry weight), and zinc (~1–3 mg/100 g dry weight), though values vary with soil and cultivation. **Vitamins:** Modest levels of vitamin C (~15–40 mg/100 g fresh fruit) and trace amounts of B-vitamins. **Macronutrients (per 100 g dried fruit, approximate):** Carbohydrates ~60–70 g (including polysaccharides and sugars such as glucose, fructose, and galactose), protein ~3–6 g, fat ~1–2 g, dietary fiber ~8–15 g. **Bioavailability Notes:** Loganin and morroniside demonstrate moderate oral bioavailability in pharmacokinetic studies (estimated 10–30% in animal models), with hepatic first-pass metabolism producing active metabolites. Tannins may reduce bioavailability of co-consumed iron and proteins. Anthocyanin bioavailability is generally low (<5%) but may be enhanced by organic acid co-presence in the fruit matrix. Traditional preparation methods (decoction, wine-steaming/processing as 'jiu zhu yu rou') may alter iridoid and tannin concentrations and improve extraction efficiency of active compounds.
Cornus officinalis exerts its effects primarily through iridoid glycosides including loganin, loganic acid, and cornuside. These compounds demonstrate antioxidant activity by scavenging free radicals and supporting cellular protection pathways. In Traditional Chinese Medicine theory, it tonifies liver and kidney yin while strengthening essence (jing).
Current evidence for Cornus officinalis is limited to in-vitro studies demonstrating antioxidant properties of its iridoid compounds. No large-scale human clinical trials have been conducted to validate traditional uses for liver and kidney support. Most research focuses on compound isolation and basic antioxidant testing rather than clinical efficacy. Traditional use spans centuries in Chinese medicine, but modern clinical validation remains lacking.
Cornus officinalis is generally considered safe when used traditionally, but comprehensive safety data is limited. No major drug interactions have been documented, though caution is advised with diabetes medications due to potential blood sugar effects. Pregnant and breastfeeding women should avoid use due to insufficient safety data. Some individuals may experience mild digestive upset with higher doses.
