Description

Silydianin is a bioactive flavonolignan compound, a key constituent derived from the milk thistle plant (*Silybum marianum*). This high-purity phytochemical is valued for its significant role in advanced research and development within the nutraceutical and pharmaceutical sectors. It is primarily sought by manufacturers and research institutions focused on hepatoprotective formulations, antioxidant studies, and the development of standardized botanical extracts.

Application

• As a reference standard for analytical method development and quality control of milk thistle extracts.
• Key active ingredient in the formulation of high-end nutraceuticals and dietary supplements targeting liver health.
• Critical component in pharmaceutical research for studying hepatoprotective mechanisms and drug interactions.
• Used in cosmeceutical applications for its antioxidant properties in skin care products.
• Building block for the semi-synthesis of related flavonolignans and derivatives.
• Biochemical tool in in-vitro and in-vivo studies investigating oxidative stress and inflammation pathways.

Quality Control

Our Silydianin is produced and tested under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical documentation, including HPLC chromatograms and full spectral data (UV, IR, MS, NMR). A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each batch and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. The material is light-sensitive and easily oxidized; prolonged exposure to air, light, or elevated temperatures should be avoided.
