Description

Vitexin 2''-o-(4'''-o-Acetyl)Rhamnoside CAS NO 80537-98-0 is a specific acetylated derivative of the flavonoid glycoside vitexin, offering enhanced properties for research and development. This compound is valued for its potential bioactive properties, making it a critical reference standard and intermediate in advanced phytochemical studies. It is primarily sought by researchers and manufacturers in the pharmaceutical, nutraceutical, and cosmeceutical industries for drug discovery, standardization of botanical extracts, and development of novel therapeutic formulations.

Application

• As a high-purity reference standard for analytical method development and quality control in pharmaceutical and herbal product manufacturing.
• For biological activity research in drug discovery, investigating potential anti-inflammatory, antioxidant, or neuroprotective effects.
• In the standardization of complex botanical extracts, particularly those derived from hawthorn (*Crataegus* spp.) or passionflower (*Passiflora* spp.).
• As a key intermediate or building block in the semi-synthesis of novel flavonoid derivatives for enhanced bioavailability or efficacy.
• For in-vitro and in-vivo studies to elucidate the structure-activity relationships (SAR) of acetylated flavonoid glycosides.
• In the development of cosmeceutical ingredients targeting skin health through antioxidant mechanisms.
