Science
Mechanism of Action
The efficacy of Rhizophora apiculata Leaf Extract is attributed to its rich composition of bioactive compounds, including tannins, flavonoids, saponins, steroids, terpenoids, and phenols. Flavonoids and phenols provide significant antioxidant activity by neutralizing free radicals and mitigating oxidative stress. Its broad-spectrum antimicrobial and antifungal properties, stemming from tannins, phenols, flavonoids, alkaloids, saponins, and terpenoids, effectively inhibit various bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa, and fungi like Candida albicans. Additionally, flavonoids contribute anti-inflammatory effects, reducing tissue edema. These combined actions synergistically promote accelerated wound healing by supporting processes like vascularization and re-epithelialization.

Key findings
- 01 In laboratory studies, Rhizophora apiculata leaf extract at concentrations between 12.5% and 100% demonstrated significant inhibitory action against pathogenic bacteria including Staphylococcus aureus (inhibition zones 5.30-3.10 mm), Aeromonas hydrophila (6.07-3.30 mm), and Pseudomonas aeruginosa (6.33-3.23 mm). A 20% methanol extract showed a 2.87 mm inhibition zone against Aeromonas hydrophila.
- 02 In an animal model, topical application of Rhizophora apiculata leaf extract at 20%, 30%, and 40% concentrations positively influenced burn wound healing. The 40% concentration proved more effective than a control drug (bioplacenton) in reducing burn area and accelerating the overall healing process.

Stability
The stability of the extract's numerous bioactive compounds is crucial for maintaining its efficacy over time. Its dual solubility (water and oil) allows for diverse formulation approaches, utilizing solvents such as methanol, ethanol, hexane, butanol, chloroform, ethyl acetate, and n-hexane to optimize the stability and bioavailability of specific components.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not conducted a specific safety review for Rhizophora apiculata leaf extract. While the FDA UNII system recognizes 'RHIZOPHORA APICULATA LEAF' with UNII 0P6I1QTW70, this serves as identification and not a safety assessment for cosmetic use. Preliminary in-vitro toxicity screenings via the Brine Shrimp Lethality Test (BSLT) reported an LC50 value of 1278.35 μg/ml, suggesting potential toxicity at certain concentrations in this specific assay.
