Overview
Eleutheroside E is a phenylpropanoid glycoside primarily extracted from Eleutherococcus senticosus, a plant traditionally used in Chinese and Russian medicine. It is one of the key bioactive markers for standardizing Siberian ginseng extracts. The compound is valued for its adaptogenic properties, helping organisms resist stressors. In industrial contexts, eleutheroside E is isolated through chromatographic techniques and used in formulations requiring precise bioactive concentrations. Its demand has grown in nutraceuticals due to increasing interest in plant-based health supplements.
Physical and Chemical Properties
Eleutheroside E crystallizes as a white powder with a melting point of 185–187°C. It is hydrophilic, dissolving readily in polar solvents like water and methanol. The molecular structure includes a syringin moiety, contributing to its stability under moderate temperatures. Spectroscopic methods (e.g., NMR, HPLC) are employed to confirm its purity, which typically exceeds 98% in commercial grades. Degradation occurs under prolonged UV exposure or high humidity, necessitating controlled storage conditions.
Main Applications
Pharmaceutical formulations leverage eleutheroside E for its potential to enhance endurance and reduce fatigue, supported by preclinical studies. It is a common ingredient in energy-boosting supplements and immune-modulatory products. Nutraceutical companies incorporate it into capsules, tablets, and functional beverages. In cosmetics, its antioxidant properties are exploited in anti-aging serums. Industrial buyers should note its inclusion in standardized extracts (e.g., 0.8–1.2% eleutheroside E content).
Safety and Storage
Eleutheroside E is non-toxic at typical dosages but requires handling per GMP guidelines to avoid contamination. Use PPE (gloves, masks) during bulk processing to prevent inhalation or skin contact. Storage mandates airtight containers with desiccants, maintained at 15–25°C. Shelf life is approximately two years when protected from light. Regulatory compliance (e.g., FDA, EFSA) varies by application; consult regional guidelines for dietary supplements or drugs.
B2B Procurement Guide
Procure eleutheroside E from suppliers with ISO 9001 certification and third-party assay reports. Key metrics include HPLC purity (≥98%), residual solvent levels, and heavy metal content (<10 ppm). Bulk pricing tiers apply at 100g+ quantities, with discounts for long-term contracts. Sample testing is recommended to verify consistency. Preferred shipping methods include temperature-controlled logistics for international orders.
