Description

Nasunin CAS NO 28463-30-1 is a potent anthocyanin pigment, specifically a delphinidin derivative, primarily isolated from the peel of eggplant (Solanum melongena). This natural compound is valued for its significant antioxidant and free radical scavenging properties, which are central to its biological activity. It serves as a key functional ingredient for manufacturers in the nutraceutical, cosmeceutical, and food coloring industries seeking natural, bioactive components.

Application

• Nutraceutical & Dietary Supplements: Formulated into capsules and tablets for its potent antioxidant support and potential health benefits.
• Functional Food & Beverage Fortification: Used as a natural colorant and bioactive additive to enhance the nutritional profile of health-focused products.
• Cosmeceutical & Skincare: Incorporated into anti-aging serums, creams, and lotions for its skin-protective effects against oxidative stress and UV radiation.
• Natural Food Coloring: Provides a stable, purple-to-blue hue in various food applications where synthetic colors are undesirable.
• Pharmaceutical Research: Employed as a reference standard and active pharmaceutical ingredient (API) intermediate in preclinical studies investigating metabolic and inflammatory pathways.
• Agricultural & Animal Feed Additives: Explored as a natural antioxidant supplement in specialty animal nutrition.
