Description

Vitexin-2-o-Rhamnoside is a bioactive flavonoid glycoside, a key marker compound derived from plants like hawthorn and passionflower. This high-purity standard is essential for research and development, providing a reliable reference for analytical and pharmacological studies. It is primarily sought by manufacturers and researchers in the nutraceutical, pharmaceutical, and botanical extract industries for quality control, standardization, and bioactivity investigations.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification and quantification of vitexin derivatives in herbal drug formulations and quality control testing.
• Nutraceutical & Dietary Supplement Formulation: Incorporated into standardized botanical extracts aimed at supporting cardiovascular health and providing antioxidant benefits.
• Biochemical & Pharmacological Research: Serves as a key compound in in vitro and in vivo studies to investigate mechanisms related to anti-inflammatory, neuroprotective, and metabolic syndrome pathways.
• Cosmeceutical Ingredients: Utilized in advanced skincare products for its potential antioxidant and skin-soothing properties.
• Analytical Chemistry: Acts as a critical calibration standard in HPLC, LC-MS, and TLC methods for the analysis of plant extracts and complex matrices.

Quality Control

Our Vitexin-2-o-Rhamnoside is produced under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods for structural confirmation, ensuring it meets the stringent requirements for use as a reference standard. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability, consistency, and compliance with your research or manufacturing specifications.

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 in a low-humidity environment. For long-term storage, consider desiccants.
