Functional Groups’ Characterization of Oil from Kaempferia Parviflora using Attenuated Total Reflectance-Fourier transfrom Infrared Spectroscopy (ATR-FTIR)

Medicinal plants refer to plants that have been traditionally and scientifically recognised for their medicinal properties. These plants contain organic compounds that can be used for various purposes in healthcare including the treatment and prevention of diseases, the alleviation of symptoms and the promotion of overall well-being. Kaempferia parviflo has been a customary practice in Thailand toutilise this both as a dietary component and a medicinal remedy. It has been employed to address various health conditions including allergies, gout, diabetes and fatigue. Thus, we extracted oils from Kaempferia parviflora via solid-liquid extraction and analyse its active compounds using Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR). The sample was further air-dried and grinded using mechanical grinder to increase its total surface area for optimisation for oil extraction process. The extraction process was performed via mixing ethyl acetate and ethanol with grinded sample (in powder form) in a ratio of 1:10. The presence of tannins and phenolic was substantiated by ATR-FTIR, thus proved its antioxidant properties.
