Description

Withanolide C is a naturally occurring steroidal lactone, a key bioactive constituent found in plants of the Solanaceae family, notably *Withania somnifera* (Ashwagandha). This compound is of significant interest for its potent biological activities, which drive its demand in advanced research and product development. It is primarily sought after by researchers and manufacturers in the pharmaceutical, nutraceutical, and cosmeceutical industries for its potential therapeutic and health-promoting properties.

Application

• Pharmaceutical Research: Serves as a high-purity reference standard and active pharmaceutical ingredient (API) intermediate for investigating anti-inflammatory, neuroprotective, and anti-cancer mechanisms.
• Nutraceutical Formulations: Used as a standardized marker compound in premium Ashwagandha extracts to ensure potency, consistency, and efficacy in dietary supplements.
• Cosmeceutical Products: Incorporated into advanced skincare formulations for its potential antioxidant and anti-aging properties.
• Biochemical Research: Employed in cell-based assays and in-vitro studies to elucidate signaling pathways and biological functions.
• Quality Control & Standardization: Acts as a critical analytical standard for the HPLC quantification of withanolides in herbal raw materials and finished products.
