Epilobium Angustifolium Extract

Short Description:

Epilobium angustifolium L.(Rose Bay Willow-herb) is a circumpolar member of the evening-primrose family (Onagraceae).
The plant is an abundant perennial that dominates many plant communities undergoing succession, quickly reclaiming disturbed ground such as cut or burned forest, thus explaining its common name, fireweed. It is also commonly known as rosebay willowherb and great willowherb. Willowherb is often employed as the English name for the worldwide species. Canadian Willowherb? has been used to describe the plant growing in Canada, which appears to possess distinct characteristics from the European plant.

Epilobium Angustifolium Extract/Epilobium Parviflorum Extract Product Description

1. Botanical Origin & Key Components
Epilobium angustifolium (Fireweed) and Epilobium parviflorum (Small-flowered Willowherb) are perennial herbs from the Onagraceae family. Their extracts are rich in bioactive compounds, including oenothein B (a hydrolyzable tannin), phenolic acids (e.g., chlorogenic acid), flavonoids, and sterols . These components contribute to their antioxidant, anti-inflammatory, and anti-aging properties.

2. Traditional & Clinically Supported Benefits

Prostate Health: Recognized by the European Medicines Agency (EMA) for alleviating symptoms of benign prostatic hyperplasia (BPH). Clinical trials confirm their efficacy in reducing urinary discomfort and improving quality of life .
Skin Protection:
- UV Damage Mitigation: Reduces UV-induced skin erythema (redness) and inhibits matrix metalloproteinases (MMPs), preventing collagen degradation and premature aging .
- Anti-Aging Effects: Downregulates senescence markers (e.g., CTGF, fibronectin) and enhances cell viability under oxidative stress .
- Hydration & Barrier Support: Modulates hyaluronidase-2 activity, preserving hyaluronic acid levels for improved skin hydration .

3. Antioxidant & Anti-Inflammatory Activity
The extracts exhibit potent free radical scavenging capacity via TRAP (Total Reactive Antioxidant Potential) assays. While their activity is lower than synthetic antioxidants like Trolox, their multi-target mechanisms (e.g., reducing MMPs, enhancing Sirtuin-1 expression) make them ideal for natural skincare formulations .

4. Cosmetic & Dermatological Applications

Recommended Use:Safety: Complies with EU and Chinese cosmetic regulations. Potential pesticide residues require strict quality control during extraction .
- Skincare Products: Anti-aging serums, sunscreens, and moisturizers (safe usage: ≤0.15% in leave-on products; ≤0.5% in rinse-off products) .
- Target Concerns: Photoaging, oxidative stress, and inflammatory skin conditions.

5. Extraction & Quality Assurance

Method: Optimized isopropanol extraction (12-day maceration) followed by rotary evaporation ensures high polyphenol yield (200 mg/mL in 1,3-butanediol) .
Analysis: HPLC-DAD-MS confirms chemical consistency, with oenothein B as a key biomarker .
