Science
Mechanism of Action
This extract functions as a powerful antioxidant by actively neutralizing free radicals and reactive oxygen species (ROS), primarily attributed to its high content of phenolic acids and flavonoids like quercetin and kaempferol. Its anti-inflammatory action involves the inhibition of key inflammatory mediators, including cyclooxygenase-2 (COX-2), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6). Furthermore, Marsilea Minuta Extract exhibits antimicrobial capabilities against both Gram-positive and Gram-negative pathogenic bacteria through compounds such as flavonoids, tannins, and alkaloids, which disrupt bacterial cell wall integrity, protein function, and cellular membranes.

Key findings
- 01 In vitro studies demonstrate potent antioxidant activity, exhibiting an IC50 of 8.94 µg/ml for DPPH radical scavenging and 37.48 µg/ml for FRAP activity, signifying robust free radical neutralizing and reducing capabilities.
- 02 Effective antibacterial activity was observed against a spectrum of pathogenic bacteria, including Pseudomonas aeruginosa and Staphylococcus aureus, with minimum inhibitory concentrations (MICs) ranging from 125-250 µg/ml in laboratory settings.
- 03 Significant anti-inflammatory effects were noted in experimental animal models, demonstrating the extract's ability to inhibit key inflammatory mediators such as cyclooxygenase-2 (COX-2), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6).

Dusting Analysis
Insufficient data is available to assess if Marsilea Minuta Extract is commonly used at sub-efficacious concentrations or to establish a specific dusting threshold.
The Formula
Formulation
Stability
The active flavonoid components of Marsilea Minuta Extract are susceptible to degradation when exposed to light, heat, oxygen, or extreme pH conditions. To maintain stability and bioactivity, optimized extraction and purification methods are crucial, alongside protective measures in formulation, such as inert atmospheres or the co-inclusion of other antioxidants. Low-temperature extraction techniques, like supercritical fluid extraction (SFE), are beneficial for preserving these thermolabile compounds.
Synergies
- Other antioxidants (e.g., Vitamin E, Ferulic Acid) for enhanced stability and protection of its active flavonoids.
Safety
Safety Profile
Safety evaluations in animal models suggest that Marsilea Minuta Extract is non-toxic at therapeutic internal doses (up to 2000 mg/kg), exhibiting no significant adverse effects on major organs. While botanical extracts are generally considered gentle and safe for topical application, specific cosmetic safety assessments by bodies like the CIR (Cosmetic Ingredient Review) or SCCS (Scientific Committee on Consumer Safety) are currently unavailable for this ingredient.
