Description

Quercetin 3-Sambubioside is a specific flavonoid glycoside, a key bioactive compound derived from plants like Hibiscus sabdariffa (roselle). This high-purity standard is critical for research and development, providing a reliable reference for analytical and biological studies. It is primarily sought by manufacturers and researchers in the nutraceutical, pharmaceutical, and cosmetic industries for its role in product formulation, quality control, and efficacy testing.

Application

• Reference Standard for Analytical Testing: Used as a primary standard in HPLC and LC-MS methods for the quantification of flavonoids in botanical extracts, herbal supplements, and finished products.
• Nutraceutical & Dietary Supplement Formulation: Incorporated into advanced supplement blends targeting antioxidant support and metabolic health, leveraging its researched bioactive properties.
• Pharmaceutical Research & Development: Serves as a key intermediate or active pharmaceutical ingredient (API) in preclinical studies investigating anti-inflammatory, cardioprotective, and neuroprotective effects.
• Cosmetic & Skincare Actives: Formulated into serums and creams for its potential antioxidant and skin-protective benefits against environmental stressors.
• Food & Beverage Fortification: Used to enhance the functional value of health-focused beverages and food products.
• Academic & Institutional Research: Essential for biochemical, pharmacological, and metabolic pathway studies in university and contract research organization (CRO) settings.
