Description

Ginsenoside Ra2 is a protopanaxadiol-type saponin, a key bioactive constituent found in Panax ginseng and related species. This high-purity reference standard is critical for research and development, enabling precise quantification, pharmacological studies, and quality control of ginseng-based products. It is essential for manufacturers and research institutions in the nutraceutical, pharmaceutical, and cosmeceutical industries seeking to standardize formulations and validate the potency of their extracts.

Application

• Pharmaceutical Reference Standard: Used as a primary chemical reference material (CRM) for the identification and assay of ginseng extracts in drug development and quality control laboratories.
• Nutraceutical & Dietary Supplement Analysis: Serves as a critical marker compound for standardizing and authenticating ginseng-containing supplements to ensure label claim accuracy and batch-to-batch consistency.
• Biomedical & Pharmacological Research: Employed in in vitro and in vivo studies to investigate its potential bioactivities, such as anti-inflammatory, neuroprotective, and anti-cancer effects.
• Cosmeceutical Ingredient Standardization: Used to benchmark and quantify Ginsenoside Ra2 content in high-end skincare and cosmetic formulations claiming anti-aging or revitalizing benefits.
• Food & Beverage Fortification: Acts as a reference for quality assurance in functional foods and beverages enhanced with standardized ginseng extracts.
• Academic Research & Method Development: Essential for universities and analytical service providers developing and validating new HPLC, LC-MS, or other analytical methods for ginsenoside profiling.

Quality Control

Our Ginsenoside Ra2 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, MS), to ensure it meets the high standards required for research and industrial applications. A Certificate of Analysis (COA) detailing specific results for purity, residual solvents, and heavy metals is provided with every shipment.

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 degradation from atmospheric moisture.
