Description

Isoginkgetin is a biflavonoid compound, a dimer of the flavonoid amentoflavone, naturally found in *Ginkgo biloba* leaves. This compound is valued for its significant biological activity and serves as a key reference standard and research chemical. It is primarily sought by professionals in the pharmaceutical, nutraceutical, and life science research sectors for its role in studying neuroprotective, antioxidant, and anti-inflammatory pathways.

Application

• Pharmaceutical Research & Development: Used as a high-purity reference standard for analytical method development, validation, and quality control of herbal extracts and finished products.
• Bioactivity Studies: A critical tool for in-vitro and in-vivo research investigating neuroprotective effects, anti-inflammatory mechanisms, and antioxidant properties.
• Nutraceutical Standardization: Employed to standardize and quantify the active biflavonoid content in Ginkgo biloba extracts and related dietary supplements.
• Academic Research: Serves as a pure chemical entity for structural-activity relationship (SAR) studies and pharmacological screening in university and institutional labs.
• Cosmeceutical Applications: Investigated for potential use in topical formulations aimed at skin protection and anti-aging due to its antioxidant profile.
