Supercritical CO2 Extraction of Serenoa repens Lipidosterolic Extract
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current saw palmetto extracts face challenges in achieving consistent and effective standardized lipid profiles due to variations in fatty acid concentrations and ratios, making it difficult to determine their therapeutic effectiveness.
Innovation Solution
A shelf-stable, supercritical CO2 fluid-extracted enhanced lipidosterolic extract of Serenoa repens (LSESr) is formulated, with a ratio of free fatty acids to total fatty acids greater than 83.0%, and enrichment of specific free fatty acids like lauric, myristic, oleic, and linoleic acids, to enhance prostate, hair, and skin health.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional extraction methods (hexane, ethanol) are used to isolate lipidosterolic extract, then the extract can be obtained, but harsh organic chemicals remain in the extract and the fatty acid profile is inconsistent
Solution Approach 1:
The patent changes the extraction parameters from conventional solvents (hexane, ethanol) to supercritical CO2, adjusting pressure and temperature conditions to achieve consistent fatty acid profiles without residual chemicals. This parameter change resolves both the consistency and safety issues simultaneously.
Solution Approach 2:
The patent replaces the chemical extraction mechanism (using harsh organic solvents) with a physical extraction mechanism (supercritical fluid extraction using CO2). This substitution eliminates residual chemical contaminants while maintaining extraction efficiency and producing consistent fatty acid profiles.
2Reliability
If the extract is standardized for specific therapeutic effects, then therapeutic effectiveness is improved, but the complexity of ensuring consistent lipid profile increases
Solution Approach 1:
The patent uses parameter changes in the extraction process (pressure, temperature, CO2 flow rate) to directly control and standardize the fatty acid profile. By adjusting these parameters, the extract achieves consistent therapeutic composition without requiring complex post-extraction standardization procedures.
Solution Approach 2:
The patent performs preliminary standardization during the extraction process itself, rather than attempting to standardize after extraction. The supercritical CO2 extraction conditions are optimized in advance to produce a consistent fatty acid profile, eliminating the need for complex subsequent standardization steps.
3Reliability
If free fatty acids are enhanced to greater than 83.0% of total fatty acids, then bioavailability and localization to target tissues are improved, but the extraction process becomes more complex
Solution Approach 1:
The patent adjusts supercritical CO2 extraction parameters (pressure, temperature, residence time) to selectively enhance free fatty acid content to greater than 83.0% of total fatty acids. These parameter changes enable high bioavailability and target tissue localization while maintaining a manageable extraction process complexity.

AI summary
A composition is formulated in a therapeutic amount to maintain and promote hair health and growth in a human in need thereof. The composition may comprise a shelf stable, supercritical CO2 fluid extracted, enhanced lipidosterolic extract of Serenoa repens (LSESr). The enhanced LSESr may have a ratio of free fatty acids to total fatty acids that is greater than about 83.0% and an enrichment of lauric, myristic, oleic and linoleic acids as free fatty acids to total free fatty acids that is about 81.0% or greater. An enrichment of linoleic and linolenic acids together may be greater than about 4.0%.
