<i>Tephrosia apollinea</i> seed: a new rich source of essential polyunsaturated fatty acids, tocopherols, sterols, and squalene

<p><i>Tephrosia apollinea</i> is a legume species, native to southwest Asia and northeast Africa, rich in bioactive flavonoids (hydrophilic compounds). <i>T. apollinea</i> seeds were not considered previously as a potential source of lipophilic compounds such as: essential fatty acids, tocopherols, sterols, and squalene, hence, the present study were performed. The oil yield in <i>T. apollinea</i> seeds amounted to 11.8% dw. The <i>T. apollinea</i> seed oil was predominated by the polyunsaturated fatty acids - linoleic (26.8%) and α-linolenic (22.7%). High levels were recorded also for oleic (27.6%) and palmitic (14.9%) acids. Four tocopherols and one tocotrienol, with the domination of γ-tocopherol (98%) were identified in <i>T. apollinea</i> seed oil. The β-sitosterol (59%), Δ5-stigmasterol (21%) and campesterol (9%) were detected as main sterols in <i>T. apollinea</i> seed oil. The total content of tocochromanols, sterols, carotenoids and squalene in the <i>T. apollinea</i> seed oil was 256.7, 338.1, 12.5 and 1103.8 mg/100 g oil, respectively. <i>T. apollinea</i> seeds oil, due to the high concentration of lipophilic bioactive compounds can find a potential application in the food, cosmetic and pharmaceutical industry.</p>
