Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for extracting active ingredients from Hibiscus hamabo's adventitious root are limited in efficiency and diversity, and there is a need for enhanced extraction methods to maximize the efficacy of these ingredients for cosmetic applications.
Innovation Solution
A two-step culturing process involving inoculation in a culture medium containing MS salt, plant growth regulators, and sucrose, followed by treatment with methyl jasmonate as an elicitor, and subsequent extraction using alcohol, decompression concentration, and freeze-drying to enhance the content of active ingredients like N-[4′-hydroxy-cinnamoyl]-aspartic acid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If simple extraction using hydrophilic solvents is used, then the extraction process is simple and easy to operate, but the extraction efficiency of active ingredients is limited
Solution Approach 1:
The patent changes the extraction parameters by using organic solvents (ethyl acetate, butanol) instead of hydrophilic solvents, and by adjusting pH levels (acidic pH 2-4 or basic pH 8-10) to enhance the extraction efficiency of active ingredients from Hibiscus hamabo adventitious root while maintaining operational feasibility through standardized laboratory procedures
2Ease of manufacture
If conventional extraction methods are used, then the extraction process is straightforward, but the diversification of efficacy of extracted active ingredients is limited
Solution Approach 1:
The patent segments the extraction process into multiple steps with different solvents and pH conditions to isolate and extract different types of active ingredients with diverse efficacies, enabling both straightforward extraction procedures and diversified functional applications
Solution Approach 2:
The patent demonstrates multi-functionality by extracting a broad spectrum of active ingredients including phenolic compounds, flavonoids, and other secondary metabolites that can be applied for various cosmetic and pharmaceutical purposes, making the extraction method universally applicable for diverse efficacy requirements
3Quantity of substance
If Hibiscus hamabo is cultivated to enhance active ingredients, then the content of active ingredients is increased, but the culturing process becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-treating the adventitious root with elicitors such as methyl jasmonate or salicylic acid before the main extraction process, which primes the plant tissue to produce higher concentrations of active ingredients and simplifies subsequent extraction operations
Solution Approach 2:
The patent changes culturing parameters including temperature (20-30°C), pH levels (5.5-7.0), and nutrient composition to optimize active ingredient accumulation while maintaining a relatively simple culturing process that can be implemented in standard laboratory conditions
