Lupeol dosage

Lupeol analysis quantifies this naturally occurring pentacyclic triterpene, found in numerous medicinal plants and vegetable oils such as neem ( Azadirachta indica ), aloe vera , olive, grape, and birch. Used for its anti-inflammatory, antioxidant, and healing properties, lupeol serves as a marker of quality and biological activity in plant extracts and cosmetic or nutraceutical formulations.

This analysis is carried out by HPLC or LC-MS/MS , reference methods for the precise quantification of triterpenes in complex matrices of natural origin.

Lupeol: a bioactive triterpene of industrial interest

Lupeol is a molecule belonging to the triterpene family, derived from the lupane skeleton. It is found in many plant species, particularly in resins, oils, bark, and leaves. It plays a key biological role in protecting plants against environmental stresses and has recognized therapeutic effects.

From a biochemical perspective, lupeol exhibits a broad spectrum of activities:

• anti-inflammatory effect through inhibition of inflammatory mediators,
• antioxidant activity and protective of cell membranes,
• skin healing and repairing properties,
• antiproliferative and immunomodulatory effect,
• mild antimicrobial action depending on the matrix and concentration.

Because of these multiple effects, lupeol has become a reference marker in the analysis of medicinal plant extracts, vegetable oils and formulations for dermatological or nutraceutical purposes.

Objectives and purpose of lupeol assay

The analysis of lupeol aims to:

• to determine the concentration of active triterpenes in plant extracts or ingredients,
• verify the conformity of batches according to established quality standards,
• to control the purity and stability of the compound during the transformation,
• validate the functional claims related to anti-inflammatory or restorative properties,
• standardize finished products to ensure consistent efficiency.

The dosage is applicable to extracts of aloe, neem, olive, birch, as well as to cosmetic or nutraceutical formulations containing triterpene fractions.

Analytical methods used

The quantification of lupeol relies on chromatographic techniques adapted to nonpolar and low-volatility compounds:

• HPLC (high-performance liquid chromatography) : used to separate and quantify triterpenes according to their UV absorption spectrum. This method is particularly suitable for oily matrices or crude extracts.
• LC-MS/MS (liquid chromatography coupled with tandem mass spectrometry) : reference method for the identification and accurate quantification of lupeol, offering optimal sensitivity and high specificity.

These methods can be coupled with a sample preparation step (liquid-liquid extraction or SPE) to concentrate the analytes and eliminate interferences.

For a complete characterization of the extracts, YesWeLab also offers the measurement of total triterpenes, the measurement of betulinol, or the measurement of ursolic acid , allowing to obtain a global view of the triterpene profile of the samples.

Industrial and scientific applications

Lupeol assay is used in several fields:

• Nutraceutical : control of the lupeol content in plant extracts used for the formulation of food supplements with anti-inflammatory or antioxidant properties.
• Natural cosmetics : evaluation of the quality of active ingredients in repairing, anti-aging, soothing or purifying skincare products based on vegetable oils or plant extracts rich in triterpenes.
• Phytochemical research : study of the triterpene profile of new plant species and analysis of the stability of lupeol in complex formulations.
• Pharmaceutical and dermocosmetic industry : validation of dosage in the quality control and product development phases.

Lupeol is often analyzed in conjunction with other bioactive compounds such as β-sitosterol, oleanolic acid or total saponins , for an integrated approach to the chemical composition of extracts.
