Quassin dosage

Quassine is a triterpene lactone with an intensely bitter flavor, extracted primarily from the wood of Quassia amara. Long used in traditional herbal medicine, it is recognized for its digestive and natural insecticidal properties, and its role as a bitter flavoring agent in herbal formulations.

Quassin dosage is essential for:

• Controlling the quality of quassia extracts
• Standardize the content of bitter active ingredients
• Meeting traceability and regulatory compliance requirements

Available analytical methods

Quassin analysis relies on liquid chromatography techniques:

• HPLC-DAD: detection by UV absorption, a method commonly used for botanical extracts
• LC-MS: mass spectrometry for precise quantification, even at low concentrations

Extraction is generally carried out using hydroalcoholic methods to ensure optimal recovery of quassin in complex matrices.

Compatible matrices

This dosage applies to the following products:

• Quassia amara wood extracts
• Plant powders or dry extracts
