Spices and herbs are well appreciated for their medicinal properties since ancient times. Till date, spices are being explored for volatile oils (essential), flavour and for addressing many chronic diseases. In the present study, we investigated the physicochemical properties, fatty acid composition, differential scanning calorimetry (DSC), elemental composition and nutraceutical compounds of fixed oils (non-volatile) from five selected spices viz., Alpinia galanga, Cinnamomum zeylanicum, Trigonella foenum-graecum, Foeniculum vulgare, and Myristica fragrans. The fixed oil (FO) content of volatiles-free powders of the five selected spices ranged from 1.58% (C. zeylanicum) to 26.43% (M. fragrans). The studied FO showed a good quality index which was analysed by estimation of free fatty acids, iodine value and unsaponifiable matter. The fatty acid analysis showed high palmitic acid in the FO of A. galanga …
