Description

Kaempferol-3-Rhamnoglucoside-7-Glucoside is a specific flavonol glycoside, a natural polyphenolic compound derived from various plant sources. This high-purity reference standard is critical for analytical research, quality control, and product development in the nutraceutical and pharmaceutical industries. It serves as an essential material for scientists and manufacturers requiring precise quantification and identification of bioactive flavonoid components.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and purity testing of herbal extracts and finished drug products in pharmacopoeial methods.
• Nutraceutical & Dietary Supplement Analysis: Essential for the quality control of flavonoid-rich supplements (e.g., Ginkgo biloba, propolis) to verify label claims and ensure batch-to-batch consistency.
• Academic & Biomedical Research: Employed in studies investigating the antioxidant, anti-inflammatory, and potential chemopreventive properties of kaempferol and its glycosides.
• Food & Beverage Ingredient Standardization: Acts as a calibration standard for quantifying flavonoid content in functional foods, beverages, and raw agricultural products for nutritional labeling.
• Cosmeceutical Product Development: Used in R&D for standardizing natural extract ingredients purported to have skin-protective benefits in cosmetic formulations.
• Method Development & Validation: Serves as a critical component in developing and validating new analytical methods (HPLC, LC-MS) for flavonoid detection and quantification.
