“…Campesterol (Peak 2), stigmasterol (Peak 3), and β ‐sitosterol (Peak 6) were confirmed on the basis of the match of their RRT values and their MS fragmentation patterns with those of authentic standards. Campesterol, β ‐sitosterol, and stigmasterol are the most common phytosterols (Bacchetti, Masciangelo, Bicchiega, Bertoli, & Ferretti, ; Boulila & Bejaoui, ; Cossignani, Blasi, Simonetti, & Montesano, ). Peak 1 and Peak 5 were identified to be 24‐methylenecholesterol and 24‐Methyldesmosterol respectively by matching RRT values and MS fragmentation patterns with those reported by Takatsitoa et al.…”

Lycium ruthenicum Murr. (LRM, Solanaceae), also called "black wolfberry" in China, is extremely tolerant drought. Although black wolfberry has seeds that are rich in oil, being considered as a potential alternative for edible oil production, little information has been found regarding its characterization. The present study evaluated the fatty acid profile of the seed oil and its phytosterol contents. Moreover, its antioxidant potential and its inhibition activities on pancreatic lipase, and cholesterol esterase (CEase) were also determined. The key fatty acids of studied oil were linoleic (74.58%), oleic (11.82%), γ-linolenic (6.60%), palmitic (4.88%), and stearic (1.40%) acids, which together comprised 99.28% of the total fatty acids. Phytosterols including 24-methylenecholesterol, campesterol, stigmasterol, dihydrolanosterol, 24-methyldesmosterol, β-sitosterol, Δ -avenasterol, cycloartenol, and Δ avenasterol were identified for the 1st time. The inhibition values (IC ) for the DPPH and ABTS radical scavenging capacities of the oil were 7.86 and 15.49 mg/mL, respectively. Additionally, LRM seed oil was also demonstrated to possess strong pancreatic lipase, and CEase inhibition activities with IC values of 12.38 and 2.63 mg/mL, respectively. The mechanism study indicated that the inhibitory manner of the oil on CEase belonged to uncompetitive inhibition of reversible inhibition. The results derived from above studies suggest that LRM seed oil could be a potential source of high value phytochemicals for developing novel functional food.

“…For comparison, lower total levels of phytosterols were shown by Montesano et al [48] in pumpkin (295 mg/100 g), and by Ying [37] in poppy seed (about 190 mg/100 g), avocado fruit (about 135 mg/100 g) and hemp (83 mg/100 g) oils. Lower and different levels of total sterols in goji berry (Lycium barbarum L.) produced in Mongolia (130.1 mg/100 g), China (55.1 mg/100 g) and Italy (42.8 mg/100 g) were determined by Cossignani et al [49]. The content of tocopherols and sterols in vegetable oils decreases with heating and storage; therefore, storage conditions, as well as distribution and display in shops, is crucial [37,43].…”

In this study, 29 cold-pressed camelina (Camelina sativa L.) oils, pressed from seeds grown in Poland and purchased directly from local producers, were analyzed. The degree of change in the tested oils’ characteristic hydrolytic and oxidative lipid values was determined. Oxidative stability was determined using the Rancimat and PDSC methods. Fatty acid and phytosterol contents were determined by GC-FID, and tocopherols by HPLC. The analyzed oils were characterized by good, but variable, quality, and met the requirements specified for cold-pressed edible oils. Highly desirable fatty acid composition, low SFA content (about 6%), high α-linolenic acid content (34.7–37.1%), and optimal PUFA n-3 to PUFA n-6 ratio (1.79–2.17) were shown. The high nutritional value of camelina oils was confirmed on the basis of high contents of tocopherols (55.8–76.1 mg/100 g), phytosterols (331–442 mg/100 g), and carotenoids (103–198 mg of β-carotene/kg). The optimal nutritional quality indices were as follows: 0.05–0.07 for the atherogenicity index (AI), and 0.1–0.2 for the thrombogenicity index (TI). The significant impact of primary (PV) and total oxidation (TOTOX) of camelina oil on oxidative stability was evaluated using Rancimat and PDSC methods. Both methods were also confirmed to be appropriate for the assessment of the oxidative stability of camelina oils.

“…Due to its special nutritional composition (free sugars, carotenoids, polyphenols, flavonoides, vitamins, fatty acids, minerals, proteins, etc.) with health benefits such as immunity enhancement, antioxidant, anti-aging and anti-tumor effects, Goji berry has been proposed as functional food and included in the category of "superfoods" [4,[7][8][9][10][11][12][13][14][15][16][17]. Other major aspects of the medicinal quality of Goji fruit are heart disease risk reduction, hypoglycaemic, hypolipidemic and neuroprotective effects, prevention of some eye diseases and male fertility facilitation [18][19][20].…”

BACKGROUND: Lycium barbarum L. has received considerable attention due to nutritional value of berries and its cultivation in Europe has attracted growing interest. OBJECTIVE: The aim of the study was characterization of Lycium barbarum L. berry cultivated in North Macedonia in terms of nutritional and functional properties and comparison with Lycium chinense M. variety. METHODS: Minerals, total proteins, sugars, antioxidant activity, fatty acids, carotenoids and polyphenols were determined and lipid indices were evaluated. Principal Component Analysis was used to describe variability of composition, while heat map to recognize the parameters significantly different for varieties. RESULTS: Lycium barbarum L. cultivated in North Macedonia represents a rich source of K, Cu, Mn, P, Zn, Mg, Fe and antioxidant compounds. Polyunsaturated fatty acids (mainly linolenic acid) were dominant in oil resulting in very low atherogenic and thrombogenic indices. A variability of 35.1% was ascribed to minerals, carbohydrates and proteins, 22.3% to ω-6 fatty acids and lipid indices of oil, 19.4% to nutrients with antioxidant activity and 13.4% to ω-3 fatty acids (n-3 and n-3/n-6 ratio). CONCLUSIONS: Chemometric analysis highlighted significant differences in terms of inorganic nutrients, antioxidant capacity, proteins, sugar profile and lipid indices in Lycium barbarum L. compared to Lycium chinense M.
