Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current resveratrol derivatives, such as resveratrol 3-O-β-glucoside, have limitations in water solubility and functionality, particularly in pharmaceutical formulations, where they exhibit poor stability and reduced tyrosinase inhibitory effects, making them unsuitable for effective skin aging prevention.
Innovation Solution
Development of resveratrol 3-O-α-glucoside, which is mixed with monohydric to tetrahydric alcohols to enhance solubility and stability, allowing for high concentration concentration and incorporation into various products like cosmetics, foods, and medicines, demonstrating improved melanogenesis suppression, hyaluronidase inhibition, anti-oxidization, cell activation, sirtuin gene activation, and anti-inflammatory properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If resveratrol 3-O-β-glucoside is used to improve water solubility and stability, then stability is improved, but water solubility remains insufficient and tyrosinase inhibitory effect is reduced
Solution Approach 1:
The patent changes the glycosidic bond configuration parameter from β to α, transforming resveratrol 3-O-β-glucoside into resveratrol 3-O-α-glucoside. This parameter change fundamentally alters the physical and chemical properties, achieving both high water solubility (approximately 10-fold higher than resveratrol) and enhanced stability, while simultaneously improving tyrosinase inhibitory effect.
2Stability of the object's composition
If resveratrol derivatives are used to improve stability, then stability is improved, but water solubility and functionality remain unsatisfactory
Solution Approach 1:
The patent modifies the glycosidic bond configuration from β to α, which fundamentally changes the molecular structure and physical properties. This parameter change results in resveratrol 3-O-α-glucoside exhibiting high water solubility, enhanced stability, and improved tyrosinase inhibitory effect, thereby resolving the functionality issue.
3Stability of the object's composition
If conventional resveratrol derivatives are used in pharmaceutical formulations, then stability is improved, but water solubility prevents effective concentration
Solution Approach 1:
The patent changes the glycosidic bond configuration parameter from β to α, creating resveratrol 3-O-α-glucoside with fundamentally improved water solubility. This parameter change enables the compound to achieve high concentrations in aqueous pharmaceutical formulations while maintaining stability, overcoming the solubility limitation of conventional derivatives.
