Owing to its distinct fatty acid composition, especially its high linoleic acid concentration, safflower (<em>Carthamus tinctorius L.</em>), an underutilized Oilseed Plant in the area, offers substantial health benefits. Its stability and nutritional value are improved by its antioxidant capacity, which is influenced by tocopherols and other phenolic compounds. The current study's objective was to examine the safflower oil's various physico-chemical characteristics, as well as its fatty acid composition using GC and total tocopherol using HPLC. The various physico-chemical properties included moisture, density, refractive index, turbidity, peroxide value, iodine value, saponification value, and acid value were determined. The fatty acid profile of safflower oil revealed thirteen different fatty acids, each with a different concentration.

Absorbance measurements demonstrated that each feruloyl derivative (FA, EF, FG, and DFG) existed in two forms in water at pH 4.6, a fully neutral form (X, X = FA, EF, FG, or DFG) and a mono-deprotonated form (X<sup>−</sup>).
