Validation of Quantitative HPLC Method for Bacosides in KeenMind

الملخص EN

Brahmi (Bacopa monnieri) has been used by Ayurvedic medical practitioners in India for almost 3000 years.

The pharmacological properties of Bacopa monnieri were studied extensively and the activities were attributed mainly due to the presence of characteristic saponins called “bacosides.” Bacosides are complex mixture of structurally closely related compounds, glycosides of either jujubogenin or pseudojujubogenin.

The popularity of herbal medicines and increasing clinical evidence to support associated health claims require standardisation of the phytochemical actives contained in these products.

However, unlike allopathic medicines which typically contain a single active compound, herbal medicines are typically complex mixtures of various phytochemicals.

The assay for bacosides in the British Pharmacopoeia monograph for Bacopa monnieri exemplifies that only a subset of bacosides present are included in the calculation of total bacosides.

These results in calculated bacoside values are significantly lower than those attained for the same material using more inclusive techniques such as UV spectroscopy.

This study illustrates some of the problems encountered when applying chemical analysis for standardisation of herbal medicines, particularly in relation to the new method development and validation of bacosides from KeenMind.
