Science
Mechanism of Action
This extract operates through a multi-faceted mechanism, primarily driven by its rich profile of bioactive phytochemicals including alkaloids, flavonoids, and phenolic compounds. Flavonoids exert significant antioxidant, anti-inflammatory, and antimicrobial actions by neutralizing free radicals and modulating cellular responses. Tannins further contribute anti-irritant and antimicrobial benefits, collectively inhibiting microbial growth and suppressing inflammatory pathways within the skin.

Key findings
- 01 In vitro studies demonstrate high antioxidant potential, achieving a half inhibition concentration (IC50) for total antioxidant activity at 49.06 µg/ml.
- 02 Effective superoxide radical scavenging activity, with IC50 values consistently around 48.52-48.58 µg/ml.
- 03 Potent DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging demonstrated by an IC50 of 42.2 µg/mL (with aqueous and methanol extracts showing IC50s up to 342.59 µg/ml).
- 04 Significant nitric oxide scavenging activity, with IC50 values ranging from 49.93 µg/mL to 328.29 µg/ml depending on the extract type.
- 05 Achieved 80.23% inhibition in iron chelating activity at 80 µg/ml.
- 06 Showed a low IC50 of 97.29 µg/ml for inhibiting lipid peroxidation (aqueous extract).
Transparency
Dusting Analysis
The ingredient exhibits potent antioxidant, anti-inflammatory, and antimicrobial activities at relatively low in vitro concentrations (IC50 values in the microgram/ml range), suggesting significant biological efficacy that makes it unlikely to be used merely as a filler.
