Laser-Irradiated Curcuma Longa Rhizome Extracts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Curcumin from Curcuma longa has poor bioavailability due to low absorption and rapid metabolism, limiting its therapeutic use despite its medicinal properties.
Innovation Solution
Laser irradiation of Curcuma longa rhizomes enhances the concentration of active components, particularly curcuminoids, resulting in an ethanolic extract with increased antimicrobial activity against multi-drug resistant bacteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional extraction methods are used, then the extraction process is simple, but the concentration of active components in the extract is low
Solution Approach 1:
Laser irradiation is applied to the Curcuma longa rhizome before extraction to pre-activate and enhance the active components. This preliminary action increases the concentration of curcuminoids and other bioactive substances in the rhizome, which then translates to higher concentration in the extracted product without complicating the extraction process itself
2Reliability
If standard curcumin is used, then the cost is low, but the bioavailability is poor due to low absorption and rapid metabolism
Solution Approach 1:
Laser irradiation changes the physical and chemical parameters of the curcuminoids and other active components in Curcuma longa. This parameter change enhances the molecular structure and properties of the active compounds, improving their absorption characteristics and metabolic stability, thereby increasing bioavailability while maintaining a simple manufacturing process
3Reliability
If conventional processing is used, then the antimicrobial activity is moderate, but the effectiveness against multi-drug resistant bacteria is insufficient
Solution Approach 1:
Laser irradiation is applied as a preliminary treatment to enhance the antimicrobial properties of Curcuma longa before extraction. This pre-treatment increases the concentration and potency of antimicrobial compounds in the rhizome, resulting in an extract with significantly improved effectiveness against multi-drug resistant bacteria

AI summary
Methods of producing, compositions containing, and methods for administering curcumin, and particularly extracts obtained from a laser irradiated rhizome of Curcuma longa having an enhanced antimicrobial activity. An ethanolic extract of the laser irradiated rhizome of Curcuma longa exhibits increased levels of bisdemethoxycurcumin and curcumin, as well as of alpha-curcumene, (-)-zingiberene, caryophyllene, and beta sesquiphellandrene as compared to those of an ethanolic extract from a Curcuma longa rhizome not irradiated by a laser.
