1. Product Description & Key Parameters
Ophiopogon Japonicus Extract (also known as Dwarf Lilyturf Extract) is a natural botanical extract derived from the dried tuberous roots of Ophiopogon japonicus (Linn. f.) Ker-Gawl., a perennial herb in the Liliaceae family. It is a classic Yin-nourishing herb in Traditional Chinese Medicine (TCM) with over 2,000 years of application, documented in Shen Nong Ben Cao Jing as a "top-grade herb" for its effects of nourishing Yin, moistening the lungs, clearing the heart, and promoting fluid production. Native to China, it is mainly distributed in Sichuan, Zhejiang, Jiangsu, and Hubei provinces, with Sichuan and Zhejiang as the core producing areas, where the mild climate and fertile soil yield high-quality raw materials.
The extract is manufactured via advanced processes including water extraction, ethanol reflux, ultrasonic-assisted extraction, purification, and spray drying, effectively preserving bioactive components such as
ophiopogonin D (core active),
ophiopogon polysaccharides, flavonoids, and amino acids. The final product is a
brownish-yellow fine powder with a characteristic mild herbal aroma, good flowability, no visible impurities, and uniform particle size. It is soluble in hot water and ethanol, moderately soluble in cold water, and slightly soluble in petroleum ether, facilitating its use in various formulations.

2. Features
- Natural & Premium Sourcing: Raw materials are selected from pollution-free, high-ecology areas in Sichuan and Zhejiang, harvested at maturity for maximum active content. Low-temperature processing retains heat-sensitive polysaccharides and saponins; no artificial colors, flavors, or preservatives are added.
- Standardized & High-Purity: Strict parameter control ensures batch consistency. Standard specs (polysaccharides ≥10%, ophiopogonin D ≥2%) meet international demands; high-purity grades (HPLC ≥98%) are available for pharmaceutical use.
- Excellent Solubility & Compatibility: Good solubility in water/ethanol and compatibility with most formulation ingredients (aqueous/alcoholic) allows flexible use in capsules, tablets, oral liquids, and skincare products without texture or efficacy interference.
- Stable Quality & Safety: Under recommended storage, active components remain stable. It is non-toxic and safe for adults at recommended doses; long-term excessive intake may cause mild gastrointestinal discomfort.
- Multi-Functional & Versatile: Integrates lung-moistening, cardioprotective, antioxidant, and immune-regulating benefits, with wide applications in healthcare, pharmaceuticals, cosmetics, and food.
3. Functions
- Lung-Moistening & Cough-Relieving: Core polysaccharides and saponins moisten the lungs, relieve dry cough and sore throat, inhibit cough reflexes, and improve chronic cough (e.g., bronchitis, pharyngitis).
- Yin-Nourishing & Fluid-Promoting: Stimulates saliva secretion, relieves dry mouth/thirst (including diabetic xerostomia), and alleviates dry skin and constipation by nourishing stomach Yin.
- Cardioprotective: Ophiopogonin D improves myocardial blood flow, lowers blood viscosity, and protects against myocardial ischemia; used in adjuvant treatment of coronary heart disease and arrhythmia.
- Antioxidant & Anti-Aging: Polysaccharides and flavonoids scavenge free radicals, reduce oxidative stress, protect cells, and delay aging; benefit skin health and systemic anti-aging.
- Immune-Regulating: Enhances macrophage phagocytosis, promotes lymphocyte transformation, and boosts immune function; suitable for immunocompromised individuals.
- Hypoglycemic & Metabolic Support: Improves sensitivity, promotes secretion, protects pancreatic β-cells, and assists in lowering blood glucose for mild hyperglycemia.
- Anti-Inflammatory & Calming: Inhibits inflammatory pathways (e.g., NF-κB), relieves respiratory inflammation, and exerts mild sedative/anxiolytic effects to improve sleep quality.
4. Application Fields
- Pharmaceutical Industry: As a raw material for Yin-nourishing, lung-moistening, and cardioprotective drugs; used in oral preparations (tablets, capsules, oral liquids) for adjuvant treatment of chronic bronchitis, coronary heart disease, and insomnia.
- Healthcare Products: Functional ingredient in capsules, tablets, oral liquids, and health teas; targeted at lung health, cardiovascular care, anti-aging, and immune enhancement. Suitable for the elderly, smokers, and those with dry cough or suboptimal immunity.
- Cosmetics & Personal Care: Added to moisturizing creams, masks, serums, and toners. Polysaccharides act as natural humectants, locking in moisture, repairing the skin barrier, soothing sensitivity, and reducing dryness and dullness.
- Food & Beverage: Natural additive in functional beverages, health teas, nutritional bars, and soups; enhances health value with its herbal flavor and benefits (moisturizing, immune support).
- Other Fields: Used in feed additives to enhance livestock immunity and growth; also applied in botanical research
