Lepidiline assay

Lepidilins are rare phenolic compounds, primarily identified in certain plants of the Brassicaceae family, such as Lepidium sativum . They are attracting increasing interest for their potential biological properties, particularly their antioxidant and protective effects. In the nutraceutical and medicinal plant fields , their quantification is an essential tool for better characterizing extracts and assessing their functional effects. Like other plant polyphenols, lepidilins require precise analysis to ensure the traceability, quality, and reproducibility of formulations containing them.

Analytical methods for the determination of lepidilins

The measurement of lepidilins relies on high-resolution chromatographic techniques:

• HPLC (High Performance Liquid Chromatography) : allows the separation and quantification of lepidilins in complex matrices such as crude plant extracts.
• LC-MS (Liquid Chromatography coupled with Mass Spectrometry) : provides increased specificity, capable of identifying molecular profiles even when compounds are present in trace amounts.

These methods are comparable to those used for other families of polyphenols, such as flavonoids or sesquiterpene coumarins .

Industrial and scientific applications

Lepidiline testing can address several needs:

• Nutraceutical : standardization of food supplements containing extracts of Lepidium or other Brassicaceae.
• Medicinal plants and botanical extracts : enhancing the value of natural ingredients by highlighting their specific phenolic compounds.
• Research and development : biochemical studies on the biological activity of lepidilins and their potential role in protection against oxidative stress.
• Innovative formulations : integration into supplements or functional products targeting cellular health and well-being.

These applications echo other analytical services offered by YesWeLab, such as the measurement of total polyphenols or isoflavones .

Matrices analyzed for lepidilins

YesWeLab's partner laboratories analyze lepidilins in various matrices: Lepidium (seed, root, leaves), concentrated plant powders, dietary supplements in capsule or tablet form, and botanical formulations for nutraceuticals. Sample preparation is tailored to each matrix to ensure reliable and reproducible results.

Quality and traceability issues

The measurement of lepidilins allows us to:

• Characterize and standardize plant extracts , highlighting their unique composition.
• Ensuring conformity and regularity between production batches is a guarantee of quality for manufacturers and distributors.
• Enhancing nutraceutical formulations by providing accurate analytical data for claims.
• Supporting scientific research with robust quantitative data.

These issues are similar to those observed for other plant biomolecules, such as trigonelline or theanine .
