Brief Introduction
Sinensetin is a naturally occurring polymethoxylated flavone mainly accumulated in citrus peels and Orthosiphon aristatus. Chemically named Pentamethoxyflavone, it features five methoxy substitutions on the flavone backbone. Compared with common flavonoids, this permethylated structure delivers improved lipophilicity and membrane permeability, making it a high-value bioactive phytochemical for cosmetic actives, dietary supplement research and pharmaceutical intermediate study.
Our Sinensetin adopts standardized purification technology from citrus raw materials. Strict HPLC testing ensures stable purity, low heavy metal residues and consistent batch-to-batch quality to satisfy industrial formulation and laboratory research demands.
Core Biological Properties
Scientific researches confirm Sinensetin owns multiple valuable bioactivities:
- Powerful antioxidant capacity to neutralize excess free radicals
- Regulates inflammatory mediators and exhibits anti-inflammatory effects
- Supports lipid metabolism and shows anti-adipogenic potential
- Acts as P-glycoprotein inhibitor, helps improve cellular absorption of co-formulated ingredients
- Displays mild antimicrobial activity against multiple strains
- Shows neuroprotective and hepatoprotective effects in in-vitro models
Industrial Application Fields
✅ Cosmetic Raw Materials
Applied in anti-aging, soothing and brightening skincare formulas. Its antioxidant property reduces oxidative stress on skin cells and relieves mild inflammatory discomfort.
