Description

Genistein 7-o-β-D-Glucopyranoside-4'-o-[α-L-Rhamnopyranosyl-(1→2)-β-D-Glucopyranoside] is a specific, high-purity isoflavone glycoside derived from natural sources. This compound matters as a key reference standard and active ingredient for research and development in nutraceutical and pharmaceutical applications, offering precise biological activity. It is primarily needed by manufacturers and R&D laboratories in the dietary supplement, functional food, and advanced cosmetic sectors seeking standardized phytoestrogen components.

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis of isoflavone content in drug formulations and herbal extracts via HPLC or LC-MS.
• Nutraceutical Ingredient: Incorporated into dietary supplements targeting women's health, bone density support, and antioxidant formulations.
• Functional Food Additive: Enriched into foods and beverages designed to provide phytoestrogen benefits.
• Cosmeceutical Actives: Serves as an active component in anti-aging and skin rejuvenation skincare products for its antioxidant properties.
• Biochemical Research: Employed in vitro and in vivo studies to investigate estrogen receptor interactions, metabolic pathways, and bioavailability of glycosylated isoflavones.
• Quality Control Material: Acts as a critical calibrant for the standardization of red clover, soy, and other legume-based raw materials and finished products.

Quality Control

Our Genistein 7-o-β-D-Glucopyranoside-4'-o-[α-L-Rhamnopyranosyl-(1→2)-β-D-Glucopyranoside] is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure compliance with stringent specifications. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccants or inert atmosphere packaging.
