Ungernia victoris Vved. (family Amaryllidaceae) is a perennial plant growing in the mountain regions of Uzbekistan and Tadzhikistan, whose leaves and bulbs are a source of drugs. We investigated the previously unstudied seed oil of U. victoris. The seeds are flat and black, with a 1000-seed weight of 14.8 g and an oil content of 12.98%. The oil is light yellow with a faint herbaceous odor. The main indices of the oil and fatty acids were reported: specific gravity (d²⁰) 0.9268, refractive index (n²⁰) 1.4710, acid number 50.19 mg of KOH/g, saponification number 202.86 mg of KOH/g, Hehner number 92.25%, unsaponifiables 2.59%, iodine number (according to Kaufmann) 151.06% (oil) and 153.20% (fatty acids), neutralization number of fatty acids 207.40 mg of KOH/g, mean molecular weight of fatty acids 270.54, and phosphatides 0.87%. The fatty-acid composition determined by gas-liquid chromatography was: palmitic 11.62%, oleic 21.35%, stearic 1.82%, linoleic 64.42%, and palmitoleic 0.79%. From the UV spectrum, the amount of conjugated dienes was 1.31%, and the qualitative composition of the fatty acids was similar to that of cottonseed oil. By enzymatic hydrolysis, the oil's triglyceride composition was: GI SSS 0.13%, GI USU 2.69%, GI SSU 1.20%, GI SSU 28.52%, GI SUS 3.16%, and GI 64.30%, with main types being triunsaturated and diunsaturated.
