Identification and quantification of boeravinone-B in whole plant extract of Boerhaavia diffusa Linn and in its polyherbal formulation

Abstract

Objective: To ascertain the authenticity of Boeravinone-B in Boerhaavia diffusa and its poly-herbal dosage form (capsule) by identification and quantification through precise and robust HPLC method. Materials and Methods: The RP-HPLC analysis was accomplished employing phosphate buffer & acetonitrile as mobile phase at a flow rate of 1.5 ml/min and 270 nm as detection wavelength. Results: The content of Boeravinone B in ingredients (hydro-alcoholic extracts of whole plant) and poly-herbal formulation of B. diffusa was estimated as 0.041 % w/w and 0.011 % w/w, respectively with good linearity R2> 0.9997 and retention time 24.413±0.004 min. Conclusion: The amount of Boeravinone- B present in B.diffusa extracts of raw drug complies with that of reported in literature. Quantification of Boeravinone-B suggested an identification mark for this drug and its different market formulations and may work as quality parameter in standardization. On the basis of percentage of Boeravinone-B the content of B.diffusa in poly-herbal formulation validate the ratio of ingredient in final formulation. This method proved its applicability in quality assessment via quantification of this marker in raw material as well as various phyto-formulations of B.diffusa and widens the acceptability criteria at international level.
