Allium ampeloprasum L., commonly known as wild leek, is an edible vegetable that has been cultivated for centuries. However, no detailed studies have been undertaken to valorize A. ampeloprasum seed oil. This study aims to evaluate the physicochemical properties, chemical composition, and antioxidant activity of A. ampeloprasum seed oil. The seed oil content was found to be 18.20%. Gas chromatographymass spectrometry (GC-MS) showed that linoleic acid (71.65%) was the dominant acid, followed by oleic acid (14.11%) and palmitic acid (7.11%). A. ampeloprasum seed oil exhibited an oxidative stability of 5.22 h. Moreover, γ- and δ-tocotrienols were the major tocols present (79.56 and 52.08 mg/100 g oil, respectively). The total flavonoid content (16.64 µg CE /g oil) and total phenolic content (62.96 µg GAE /g oil) of the seed oil were also determined. The antioxidant capacity of the oil, as evaluated using the ABTS assay (136.30 µM TEAC/g oil), was found to be significant. These findings indicate that A. ampeloprasum seeds can be regarded as a new source of edible oil having health benefits and nutritional properties.

Physicochemical Properties and Biological Activities of Garlic (Allium sativum L.) Bulb and Leek (Allium ampeloprasum L. var. Porrum) Leaf Oil Extracts


The result indicated that oils extracts of both garlic bulb and leek leaves demonstrated considerable biological activities as antioxidant and antimicrobial potentials. Leek oil was found to have stronger antioxidant and antibacterial potential. However, garlic bulb oil demonstrated better antifungal potential. Both garlic and leek oil extracts exhibited marked inhibition activity against bacteria at high concentrations. Therefore, the oil extracts of both Allium spp. can be used as a potential source of ingredients for sustainable pharmaceutical and nutraceutical industries in further study conducted on them.

The plant has diuretic, anthelmintic, anticholesteremic, antiseptic, antispasmodic, cholagogue, sudorific, laxative, expectorant, antipyretic, tonic and vasodilatory properties. It is recommended for the treatment of kidney problems, atherosclerosis, heart diseases, gallstones, kidney stones and dropsy. Also, it is used against exhaustion, rheumatism, rickets, tuberculosis, pharyngitis, laryngitis, tracheobronchitis and constipation. It is applied externally to the skin against eczema, psoriasis and other skin problems. The herbal tea is used against cough, chronic and acute bronchitis, heartburn, stomach and duodenal ulcers and the inflammations of the digestive tract. Finally, the plant juice is considered to have heart-healthy benefits, as well it helps to detox smokers’ bodies.
