Background: Olanzapine (OLZ) is one of most recommended drugs for the treatment of schizophrenia while metformin (MET) is the most commonly used hypoglycemic agent. Aim: Development and validation of two green, sensitive and accurate chromatographic methods for the simultaneous determination of OLZ along with the co-prescribed, MET. Materials & methods: TLC-densitometric method with a developing system consisting of methylene chloride:methanol:ethyl acetate:triethylamine (4:4:5:0.1, by volume) and a reversed-phase (RP)-HPLC method where the chromatographic separation was performed using ethanol:water mixture (50: 50, v/v) as a mobile phase. Results: TLC-densitometric method had linearity over concentration ranges of 160–4000 ng/band for OLZ and 150–4500 ng/band for MET, while RP-HPLC method was linear and validated over concentration range of 300–20000 ng/ml for OLZ and MET. Conclusion: Pharmacokinetic study was successfully performed and suggested the possibility of co-administration of MET with OLZ and their further formulation in one pharmaceutical preparation to enhance patient’s compliance.

The aim of the present study was the development and validation of a simple, precise and specific reversed phase HPLC method for the simultaneous determination of coumarin, cinnamyl alcohol, cinnamaldehyd, acid cinnamic, eugenol, cinnamyl acetat, acid 2-hydroxycinnamic in cinnamon. The substances were extracted from the sample matrix with methanol, shaken at room temperature for 30 minutes and determined by HPLC-PDA on the following conditions: column C18 sunfire (250 × 4.6 mm, 5 µm), mobile phase 30mM ammonium acetate and methanol-acetonitrile (50:50) using gradient. The recovery > 90%, the repeatability has RSD < 7.3%, the LODs and LOQs of2-hydroxycinnamic acid, coumarin, cinnamaldehyd, cinnamyl alcohol, eugenol were 1 µg/g and 3.3 µg/g, respectively; the LODs and LOQs of cinnamic acid, cinnamyl acetate were 2 µg/g and 6.7 µg/g, respectively. The method has been applied to analyze the samples.
