Morels ( spp.) are valuable medicinal and edible mushrooms. In this study, chemical profiles of aromas and lipophilic extracts of black morel () grown in China were analyzed by gas chromatography/mass spectroscopy, along with the evaluation of antioxidant and antimicrobial activities for the lipophilic extracts. Sixty-five compounds in total were identified from the aromas, and 1-octen-3-ol was the main component for aromas of fresh (34.40%) and freeze-dried (68.61%) black morels, while the most abundant compound for the aroma of the oven-dried sample was 2(5)-furanone (13.95%). From the lipophilic extracts, 29 compounds were identified with linoleic acid as the main compound for fresh (77.37%) and freeze-dried (56.46%) black morels and steroids (92.41%) as the main constituent for an oven-dried sample. All three lipophilic extracts showed moderate antioxidant activities against 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) with the IC values ranging 7.56 ∼ 17.52 mg/mL and 5.75 ∼ 9.73 mg/mL, respectively, and no obvious antimicrobial activity was observed for lipophilic extracts. The drying methods affect the chemical profile of black morel, and freeze-drying was favorable for retaining nutrients and morel smell. This is the first report on the aroma and lipophilic extracts of grown in China.

Background: Edible oils are susceptible to contamination with polycyclic aromatic hydrocarbons (PAHs) throughout production, storage, and transportation processes due to their lipophilic nature. The necessity of quantifying PAHs present in complex oil matrices at trace levels, which bind strongly to impurities in oil matrices, poses a major challenge to the accurate quantification of these contaminants. Therefore, the development of straightforward and effective methods for the separation and enrichment of PAHs in oil samples prior to instrumental analysis is paramount to guaranteeing food safety.

Commercial ascorbyl-6-O-esters (AEs) are composed of saturated fatty acids with relatively high melting points, resulting in limited solubility in lipophilic media. Therefore, a lipase-catalysed synthesis and purification method for ascorbyl-6-O-oleate (AO) was proposed in this study. The esterification synthesis (i.

Accurate determination of plasma protein binding (PPB) is crucial in understanding the pharmacokinetics and pharmacodynamics of drugs, particularly for highly bound compounds where traditional methods may fall short. In this study, we present a pioneering approach for the precise determination of PPB that takes advantage of the lipophilicity of highly bound compounds. Twenty four highly bound compounds (with a fraction unbound (f) from 10 to 10) were tested with the most commonly used method, i.

Essential fatty acids (EFAs) in edible oils are crucial for human nutrition. However, their high unsaturation renders edible oils susceptible to oxidation during storage and processing. The addition of lipophilic antioxidants is an effective strategy to inhibit oxidation and safeguard the nutritional integrity of edible oils.
