Biochanin A (isoflavone) dosage

Biochanin A (CAS: 491-80-5) is a methylated isoflavone found primarily in red clover (Trifolium pratense) and, to a lesser extent, in other legumes. It is widely studied for its phytoestrogenic, antioxidant, anti-inflammatory, and neuroprotective properties. Its potential role in hormonal health, particularly in supporting menopause, explains its frequent use in dietary supplements for women.

Why measure biochanin A?

Biochanin A dosage is essential for:

• Standardizing plant extracts rich in isoflavones
• Validate the composition of active ingredients in nutraceutical formulations
• Ensure compliance with health or nutritional claims
• Evaluate bioavailability in clinical or R&D studies
• Control the quality of raw materials and finished products

Biochanin A acts as a metabolic precursor to genistein and daidzein, two other active isoflavones. Its dosage is therefore an important indicator of the potential effectiveness of plant extracts.

Proposed analytical methods

The analysis of biochanin A is carried out by liquid chromatography, with reliable and validated methods:

• HPLC-DAD (High Performance Liquid Chromatography – Diode Array Detector): reference method for separating and quantifying isoflavones with UV detection.
• LC-MS/MS (Liquid chromatography coupled with tandem mass spectrometry): high-precision method, suitable for complex matrices or low concentrations.

These techniques are capable of discriminating biochanin A from other isoflavones present in plant extracts, guaranteeing a specific and reproducible measurement.

Affected matrices

The dosage can be applied to different galenic forms or plant ingredients:

• Standardized extracts of red clover
• Plant powders and botanical raw materials
• Capsules, tablets or liquid supplements
• Functional ingredients for the food industry or nutraceuticals
• Products enriched with phytoestrogens

Industrial applications

Biochanin A dosage is particularly useful for:

• The formulation of supplements aimed at menopause or hormonal balance
• The development of natural ingredients with moderate estrogenic activity
• Standardization of plant extracts according to technical or regulatory specifications
• Monitoring asset stability during storage
• Evaluation of the overall isoflavone profile in plant complexes
