acid A is a unique polyphenol naturally present in Leontopodium alpinum (edelweiss), an emblematic plant of alpine regions. This compound has become a major phytotherapeutic and cosmetic marker due to its potent antioxidant, anti-inflammatory, and cell-protective properties.
Its concentration is particularly sought after in plant extracts used in natural cosmetics, anti-aging skincare, or in soothing and protective formulations. Precise quantification of leontopodic acid A not only allows for the optimization of active ingredients but also ensures the standardization, quality, and traceability of finished products.
Available analytical methods
The analysis of leontopodic acid A relies on high-performance chromatography techniques:
- HPLC-DAD (diode array liquid chromatography): a common method for detecting phenolic compounds in plant extracts. It allows for specific detection at different wavelengths and is suitable for cosmetic matrices or hydroalcoholic extracts.
- LC-MS/MS (liquid chromatography coupled with mass spectrometry): recommended for complex matrices or low concentrations. It ensures high specificity and sensitivity, allowing the differentiation of leontopodic acid A from other similar polyphenolic acids.
The analyses are carried out in partner laboratories selected for their expertise in phytochemistry, in compliance with quality and regulatory requirements (ISO 17025, COFRAC, etc.).
Matrices analyzed
Leontopodic acid A is generally measured in the following products:
- Edelweiss plant extracts (dry powders, hydroalcoholic extracts, glycerol extracts, supercritical CO₂ extracts)
- Active cosmetic ingredients incorporated into creams, serums or lotions
- High-end natural formulations with anti-aging, antioxidant or UV protection properties
- Nutraceutical products based on edelweiss or antioxidant complexes
Verification of leontopodic acid A content is essential to meet manufacturers' specifications, justify functional claims and enhance the marketing value of extracts.
Additional analyses are available from YesWeLab
YesWeLab also offers a range of complementary analyses to characterize edelweiss-based extracts or extracts enriched with antioxidant compounds. Among the most relevant services are:
- Chlorogenic acid dosage
→ Antioxidant polyphenol present in many plants, it can be combined in extract complexes. - Total flavonoid dosage (e.g., quercetin, luteolin, vitexin)
→ To assess the overall antioxidant potential of a plant or cosmetic extract. - Evaluation of overall antioxidant activity (DPPH, ORAC methods)
→ These tests allow the measurement of specific markers to be complemented by a functional measurement of antioxidant effectiveness. - Heavy metal testing (lead, arsenic, cadmium, mercury)
→ Essential analysis for the safety of plant extracts used in cosmetics or nutraceuticals.
These analytical services ensure a complete characterization of assets, with a view to regulatory compliance, product valuation and market differentiation.
