Description

Bilobalide CAS NO 33570-04-6 is a potent, naturally occurring sesquiterpene trilactone compound primarily isolated from *Ginkgo biloba* leaves. This bioactive constituent is highly valued for its significant neuroprotective and antioxidant properties, making it a critical ingredient for advanced research and product development. It is essential for manufacturers and researchers in the nutraceutical, pharmaceutical, and cosmeceutical industries seeking to formulate products that support cognitive health and combat oxidative stress.

Application

• Pharmaceutical Intermediates: Serves as a key active pharmaceutical ingredient (API) or intermediate in the development of neuroprotective drugs and cognitive enhancers.
• Nutraceutical Supplements: A vital component in high-quality dietary supplements and nootropics aimed at improving memory, focus, and overall brain function.
• Cosmetic & Skincare Formulations: Incorporated into anti-aging and protective skincare products for its potent antioxidant activity, helping to shield skin from environmental damage.
• Biomedical Research: Used extensively in preclinical and clinical studies to investigate mechanisms of neuroprotection, apoptosis, and oxidative stress pathways.
• Standard Reference Material: Employed as a certified reference standard (CRS) for the quality control and standardization of *Ginkgo biloba* extracts and finished products.
• Veterinary Health Products: Formulated into supplements for companion and performance animals to support neurological health and cognitive function.
