Description

Eleutheroside A is a bioactive phenylpropanoid glycoside compound, valued for its significant role as a key marker constituent in quality control and standardization of extracts derived from *Eleutherococcus senticosus* (Siberian ginseng). Its precise quantification is critical for ensuring the potency, consistency, and efficacy of final formulations. This high-purity standard is essential for manufacturers and research institutions in the nutraceutical, pharmaceutical, and cosmeceutical industries.

Application

• Reference Standard for Herbal Extracts: Primary application as a certified reference material (CRM) for the identification and assay of Eleutheroside A in Siberian ginseng raw materials and finished products.
• Nutraceutical & Dietary Supplement Formulation: Used in the development and quality assurance of standardized adaptogenic supplements targeting stress relief, immune support, and physical endurance.
• Pharmaceutical Research & Development: Serves as a key intermediate or active pharmaceutical ingredient (API) in preclinical studies investigating anti-fatigue, neuroprotective, and anti-inflammatory properties.
• Cosmeceutical Ingredients: Incorporated into advanced skincare formulations for its potential antioxidant and anti-aging benefits.
• Analytical Laboratory Use: Essential for method development, validation, and routine quality control testing in analytical chemistry laboratories (HPLC, LC-MS).
• Academic & Clinical Research: Used as a pure compound in biochemical, pharmacological, and metabolic studies to elucidate mechanisms of action.

Quality Control

Our Eleutheroside A is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and industrial applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting purity, residual solvents, and other critical parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture. For long-term storage, consider desiccants or inert atmosphere.
