Introduction: The need for quality control of herbal drugs is in demand in order to ensure the purity, safety and efficacy of herbal products. A total of 19 elements including essential and non-essential elements were characterized in five commercial samples of Triphala churna using WD-XRF spectrometry. Method: The WD-XRF method was validated for each element by a pre-calibrated program using five Chinese certified reference materials of vegetable standards (NCS ZC73012, NCS ZC73013, NCS ZC73017, NCS ZC85006 and NCS DC73348). Results: The following elements were detected in all the samples out of 19 elements tested with increasing order of concentrations (mg/kg): Cr (3) \< Cu (7) \< Ba (24) \< Zn (31) \< Pb (46) \< Mn (57) \< S (700) \< Na (1064) \< Mg (1250) \< Fe (1329) \< P (1400) \< Cl (2960) \< Ca (3110) \< Si (4350) \< K (15130). Lead (41-46 mg/kg), a nonessential element was found above its PDE limit (\≤ 10 mg/kg). Conclusion: WD-XRF method was found simple, rapid, reliable and non-destructive technique to investigate the elemental concentrations in herbal drugs.
