Sweroside dosage

Sweroside analysis quantifies this bitter iridoid glycoside found primarily in gentian (Gentiana lutea) , but also in vervain (Verbena officinalis) and other bitter medicinal plants. Used in herbal medicine for its digestive, cholagogue, and tonic effects, sweroside is a quality marker in products made from bitter herbs.

The analysis aims to ensure the standardization of plant extracts and to verify the conformity of food supplements and natural ingredients to the expected specifications.

Analytical methods

Sweroside is quantified by liquid chromatography using two main approaches:

• HPLC-DAD (high-performance liquid chromatography) : reference method for the accurate quantification of iridoids in extracts and formulations.
• LC-MS (liquid chromatography coupled with mass spectrometry) : allows specific detection, particularly in complex or multicomponent matrices.

Analyses can be based on European Pharmacopoeia or ISO , guaranteeing the reliability and traceability of results.

Industrial applications

Sweroside analysis is particularly used in the following sectors:

• Nutraceuticals : standardization of gentian or verbena extracts in food supplements for digestive or tonic purposes.
• Phytotherapy : characterization of medicinal plants rich in iridoids.
• Natural cosmetics : formulation of soothing or revitalizing products incorporating bitter extracts.
• Quality control : identification of any adulteration or substitution of plant-based ingredients.

Matrices analyzed

• Extracts of gentian, verbena, figwort, valerian
• Plant powders or dry extracts
• Liquid or capsule food supplements
• Phytotherapy formulations

Further analyses recommended

For a complete characterization of iridoids and bitter compounds, YesWeLab recommends combining:

• Gentiopicroside assay : another major iridoid found in gentian roots,
• Loganoside assay : a related compound present in several plant species,
• Verbascoside (acetoside) dosage : a phenol with antioxidant and anti-inflammatory properties,
• Catalpol assay : another iridoid used for purity control of extracts.
