A precise and reliable reversed-phase high-performance liquid chromatographic method with ultraviolet detection was developed and validated to determine cinitapride in human plasma. After liquid-liquid extraction, chromatographic separation was achieved on a Nucleosil C18 (25 cm × 4.6 mm, 5 µm) column with an isocratic elution consisting of 10 mM ammonium acetate (pH 5.2), methanol, and acetonitrile, 40 : 50 : 10, v/v/v. The developed method was validated as per US FDA guidelines for its linearity, selectivity, sensitivity, precision, accuracy, and stability. Satisfactory findings were obtained from the validation studies. The linearity range of the method was 1 to 35 ng/mL while the extraction recovery of cinitapride in human plasma was more than 86%. The percent coefficient of variation of both intraday and interday precision was ≤7.1%.

Tea tree oil, an active ingredient of skin, hair and nail care cosmeceuticals, has claims for topical antimicrobial, analgesic and anti-inflammatory activity. Its complex composition is governed by ISO 4730:2017. Terpinene-4-ol is the principal constituent of the oil (35% - 48%) followed by γ-terpinene (14% -28%), α-terpinene (6%-12%) and 1,8-cineole (≤15%). A reversed-phase, isocratic high performance liquid chromatographic method has been developed and validated for routine determination of tea tree oil based on1,8-cineole content in bulk and commercially available cosmeceuticals using C18 column, methanol-water (70:30 v/v) as mobile phase and flow rate of 1mL/min. UV detection was done at 200 nm. Linearity of the method was established for 20-100μL/mL (R2 = 0.9992) with LOD, LOQ values of 0.5594 μL/mL and 5.5941μL/mL respectively. The % RSD values for robustness and precision were <1% and recovery ranged between 99.09-102.96%. The method was successfully applied for determination of 1,8-cineole content in cosmeceuticals.
