Raw Material & Quality Control
Raw material of Esculin is derived from the dried bark of Fraxinus rhynchophylla Hance, as specified in the Chinese Pharmacopoeia.
Content assay is performed using HPLC analysis in accordance with Chinese Pharmacopoeia standards to ensure accurate quantification and consistency.
The product is standardized using Esculin reference substance issued by the National Institutes for Food and Drug Control (NIFDC), ensuring compliance with official pharmacopeia requirements.
What is Esculin
Esculin (also known as aesculin) is a natural coumarin glycoside compound extracted from the bark of Fraxinus rhynchophylla.
It is a bioactive plant-derived ingredient widely used in cosmetic, pharmaceutical, and nutraceutical formulations due to its antioxidant, anti-inflammatory, and photoprotective properties.
Esculin is commonly applied in skincare formulations targeting skin soothing, brightening, and protection against environmental stress.
What are Main Components of Esculin
Esculin is a naturally occurring coumarin glycoside and is considered a single purified bioactive compound rather than a multi-component extract.
Esculin (Aesculin)
The main active form responsible for its antioxidant, anti-inflammatory, and photoprotective biological activities.
Aesculetin (Related Metabolite)
Aesculetin is the hydrolyzed aglycone form of esculin, which shares similar antioxidant and anti-inflammatory properties.
What are the benefits of Esculin
Anti-inflammatory Mechanism
Esculin helps modulate inflammatory mediators, reducing oxidative stress and supporting skin barrier stability.
Antioxidant Protection
It scavenges free radicals and helps protect skin cells from environmental and UV-induced oxidative damage.
Photoprotective Activity
Esculin absorbs UV-related stress and helps reduce photoaging effects caused by long-term sun exposure.
Skin Brightening Support
It helps regulate melanin activity and supports improvement of uneven skin tone and dull complexion.
Formulation Stability Advantage
Esculin exhibits good compatibility in cosmetic formulations and can enhance stability in sensitive skincare systems.
