Loganic acid dosage

Loganic acid (CAS 18524-94-2) is a glycosylated iridoid naturally present in several medicinal plants belonging to the Rubiaceae, Gentianaceae or Loganiaceae families. It is notably found in extracts of Gentiana lutea, Cornus officinalis or Strychnos nux-vomica. This acid is recognized for its anti-inflammatory, antioxidant, neuroprotective and immunomodulatory properties, which justify its use in nutraceutical or phytotherapeutic formulations.

Why measure loganic acid?

The dosage of loganic acid allows:

• Characterize plant extracts for therapeutic, nutritional or cosmetic use.
• Control the quality and standardization of botanical raw materials.
• Check regulatory compliance in the case of health claims.
• Promote functional extracts in food supplements or wellness products.

The precise measurement of this iridoid is an indicator of biological potency, particularly in anti-inflammatory or tonic extracts.

Analysis methods used

Loganic acid is quantified by HPLC-DAD (high-performance liquid chromatography with diode-array detection) or LC-MS/MS (liquid chromatography coupled with tandem mass spectrometry). These techniques allow this iridoid to be distinguished from other similar compounds present in plant matrices, while ensuring high specificity, sensitivity and reproducibility.

Analyzed matrices

• Standardized plant extracts
• Powders of roots or aerial parts
• Herbal teas and medicinal decoctions
• Food supplements (capsules, tablets, liquids)
• Complex phytotherapeutic formulations

Related analyses in the YesWeLab catalog

In addition to the dosage of loganic acid, several other analyses can be used to comprehensively characterize plant extracts and guarantee their efficacy, stability and conformity:

• Gentiopicroside dosage
  → Another iridoid present in gentian, often dosed together with loganic acid in digestive or tonic extracts.
• Total polyphenols assay
  → Allows the overall antioxidant potential of the extract to be assessed, often associated with anti-inflammatory efficacy.

These services are available individually or integrated into tailor-made analytical plans, adapted to the requirements of the nutraceutical, cosmetic or medicinal plant sectors.
