Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for extracting and purifying compounds from plants often result in inefficient separation and degradation of valuable compounds, failing to fully utilize plant resources and obtain high concentrations of desired molecules.
Innovation Solution
A process integrating green distillation and extraction methods to concentrate phenylpropanes and flavonoids from Lippia origanoides, allowing for in-situ fractionation during distillation and reuse of residual biomass, using steam or hydrodistillation, and subsequent hydroalcoholic or supercritical carbon dioxide extraction to achieve high concentrations of thymol, carvacrol, and flavonoids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional independent extraction methods are used to obtain compounds from plants, then specific compounds can be isolated, but other valuable compounds are degraded or lost
Solution Approach 1:
The extraction process is segmented into multiple sequential stages, each targeting different families of compounds. First, essential oils are extracted by distillation, then phenylpropanes are isolated from the distillation residue, and finally flavonoids are obtained from the remaining biomass. This segmentation allows each extraction stage to optimize for specific compounds without degrading others, thereby increasing the total quantity of valuable compounds obtained while minimizing loss.
2Productivity
If single-stage extraction is used to obtain a specific compound, then that compound can be isolated, but the overall utilization of plant material is inefficient
Solution Approach 1:
The extraction system is designed with multi-functionality to handle different compound families through sequential operations. The same plant material serves multiple purposes: first as a source of essential oils via distillation, then the residue becomes the feedstock for phenylpropane extraction, and the remaining biomass is used for flavonoid isolation. This universal approach allows the system to maximize productivity by extracting multiple valuable compounds from a single raw material input, rather than performing separate extractions for each compound family.
3Ease of manufacture
If traditional extraction processes are used, then simple processing is achieved, but separation and purification efficiency is insufficient
Solution Approach 1:
The process uses intermediate separation stages with distinct functions to achieve high purification efficiency while maintaining manufacturing simplicity. Each extraction stage acts as an intermediary step that progressively isolates different compound families: distillation serves as an intermediary to separate volatile essential oils, followed by an intermediary filtration and concentration stage for phenylpropanes, and finally an intermediary extraction stage for flavonoids. These intermediary steps enable precise separation without requiring complex single-stage processes.
