High oleic vegetable oils have been attracting more and more research attention in recent years due to its benefit towards human health. This was because that the high oleic vegetable oils contained more oleic acid C18:1 than the traditional typical vegetable oils, and the oleic acid in the high oleic oils were around 70 or more 1 . Many studies have reported that the oleic acid, a kind of monounsaturated fatty acids MUFA , was helpful to reduce the risk of cardiovascular diseases, such as coronary heart disease and atrial fibrillation 2 4 . In contrast, PO contained a higher content of palmitic acid C16:0 and steric acid C18:0 , both of which were saturated fatty acids SFA . They could increase serum LDL-C levels, and might have a negative effect on human health 2, 5, 6 . According to 2015-2020 Dietary Guidelines for Americans, intake of saturated fats should be controlled to less than 10 of calories per day through substituting unsaturated fats for them and intake of fats rich in oleic acid, such as olive oil and nuts,

“…The fragments with m/z 575.63 ([DG 16:0_18:2] + ), m/z 577.63 ([DG 16:0_18:1] + ), m/z 601.65 ([DG 18:1_18:2] + ) were formed by a loss of C 18:1 , C 18:2 , and C 16:0 along with ammonia, respectively. It was suggested that the signal intensity of [DAG] + was dependent on the length of acyl chains (Zhang et al, 2016). TG 18:2_18:1_16:0 represents the structure of linoleyl‐oleoyl‐palmitoyl‐glycerol.…”

Ginkgo biloba is a living fossil and traditionally known as a source of pharmaceuticals and cosmetics, largely because of the lipids in the kernels. In the present study, fatty acids, triacylglycerols, micronutrients, and oxidative stabilities of G. biloba kernel oils from four major different cultivated regions in China were systematically analyzed. The results showed that the kernel oils contained more than 26 triacylglycerol species with high contents of linoleic acid (42.04–43.01%), oleic acid (14.33–18.00%), and trans‐vaccenic acid (15.13–16.86%). Functional fatty acids such as trans‐vaccenic acid, palmitoleic acid, and podocarpic acid were particularly enriched in the oils. In addition, high levels of tocopherols (173.41–272.18 mg/100 g) and 304.09–673.26 mg/100 g of phytosterols in the oils contributed to significantly improve their oxidative stabilities. In particular, α‐tocopherol (106.63–127.35 mg/100 g), γ‐tocopherol (41.41–133.65 mg/100 g), campesterol (53.22–139.88 mg/100 g), and β‐sitosterol (245.50–522.62 mg/100 g) were the dominant micronutrients; while γ‐tocopherol significantly affected oxidative stabilities of the four oils from different regions. It is suggested that the G. biloba kernel oils are ideal sources for high‐valued usages in skin care purpose, physical therapy, functional food, and nutritional supplements.

“…The potential of ELSD in the analysis of different lipid classes has been established. [ 25 ] Even though Refractive index detectors (RID) are compatible with HPLC, they are limited by the presence of only one single mobile phase, leading to poor ability to separate complex samples effectively. Moreover, the main disadvantage of UV‐based detectors is their limited quantification ability.…”

Phospholipids are the main constituent of cellular membranes and have recently been identified to have diagnostic value as biomarkers for many diseases. Accordingly, much emphasis is now laid on developing optimal analytical techniques for the phospholipid profiles of various biological samples. In the present study, different classes of phospholipids are first separated by optimized hydrophilic interaction chromatography with evaporative light scattering detector (HILIC‐ELSD). The phospholipids in each class are then identified by ultraperformance liquid chromatography‐quadrupole time‐of‐flight mass spectrometry (UPLC‐Q‐TOF‐MS). Validation results confirm that this approach meets the requirements of quantitative analysis. Finally, the approach is adopted to analyze the phospholipid profiles in Caenorhabditis elegans. A total of 111 phospholipid species is identified according to the mass fragments. Major fatty acyl chains in phospholipids are found to be formed by oleic acid (C18:1), arachidonic acid (C20:4), and eicosapentaenoic acid (C20:5). Overall, this study improves current knowledge on analytical techniques of the phospholipid composition in C. elegans and provides a basis for future lipidomics research. Practical applications: Phospholipids reportedly play a crucial role in the development of many diseases. Until now, only a small portion of phospholipids in Caenorhabditis elegans has been reported by using one‐dimensional analysis strategy. The offline 2D liquid chromatography method developed in this study identifies 111 phospholipid species in Caenorhabditis elegans. The obtained phospholipid profiles complement the lipid database of Caenorhabditis elegans. The study also provides the basis for the future development of a 2D online approach.
