Description

Kaempferol-3-o-Glucorhamnoside is a specific flavonoid glycoside, a naturally occurring bioactive compound derived from various plant sources. This high-purity standard is critical for research and development, serving as a key reference material for analytical and biological studies. It is primarily utilized by the pharmaceutical, nutraceutical, and life science industries for applications in drug discovery, quality control of botanical extracts, and investigating the health benefits of flavonoids.

Application

• Pharmaceutical Reference Standard: Used for the identification, assay, and purity testing of flavonoid-containing drugs and botanical extracts in QC/QA laboratories.
• Nutraceutical & Dietary Supplement Research: Serves as a biomarker and active ingredient standard for developing and standardizing antioxidant and anti-inflammatory supplements.
• Academic & Biomedical Research: Employed in in vitro and in vivo studies to investigate potential therapeutic effects, including anti-cancer, cardioprotective, and neuroprotective activities.
• Cosmeceutical Development: Acts as a standard for formulating and testing skin care products targeting UV protection and anti-aging benefits due to its antioxidant properties.
• Food & Beverage Analysis: Used as an analytical standard to quantify flavonoid content in functional foods, beverages (like teas and wines), and for authenticity testing.
• Biochemical Pathway Studies: Utilized in metabolic and enzymatic studies to understand the biosynthesis and degradation pathways of flavonoid glycosides in plants.
