Abstract :
A high-performance liquid chromatography method employing diode array detection was developed to determine levels of the 6-gingerol and thymol simultaneously, which are present in a natural complex matrices found in ayurvedic commercial product NBIOTIC Premix. Effective chromatographic separation of 6-gingerol and thymol was achieved using a Phenomenex Luna5µ (RP C18, 25 cm × 4.6 mm × 100Å) column with isocratic elution of the mobile phase composed of acetonitrile and water in 50:50 ratio. The proposed HPLC method was statistically validated with respect to linearity, range, precision, accuracy, selectivity, and robustness. Calibration curves were linear in the ranges of 6.0–48.0 µg/ml for 6-gingerol and 15.0–75.0 µg/ml thymol, respectively, with correlation coefficients >0.996. The HPLC method was applied to herbal formulation NBIOTIC Premix, in which the phytoconstituents were successfully quantified with good recovery values with no interfering peaks from the excipients.
