Glycolipids from edible plant sources were accurately quantified by silica-based, normal-phase high-performance liquid chromatography using an evaporative light-scattering detector. Five major glycolipid classes (acylated steryl glucoside, steryl glucoside, ceramide monohexoside, monogalactosyldiacylglycerol, and digalactosyldiacylglycerol) were separated and determined with a binary gradient system consisting of chloroform and methanol/water (95:5, vol/vol) without any interference from other lipid classes and pigments. The described method was applied to 48 edible plants available in Japan including cereals, legumes, vegetables, and fruits. Examined plant species contained glycolipids in wide concentration ranges, such as 5-645 mg/100 g tissue.

The antimicrobial efficacy and the impact on sensory quality of preservatives from different natural sources can vary dramatically. This makes it challenging for manufacturers to incorporate natural preservatives in shelf-stable beverage formulation. This study compares new-to-market natural glycolipids (NG) derived from Dacryopinax spathularia and white button mushroom extract (WBME) containing chitosan from Agaricus bisporus.

Article Synopsis
- A new bacterial strain called REN37 was isolated from Sichuan's Baijiu fermented grains and is identified as a Gram-negative, non-motile, rod-shaped organism belonging to the genus Isoalcanivorax.
- The strain thrives best at temperatures of 32-37°C, a pH of 6.0-7.0, and with 1-2% NaCl, and shows significant genetic differences from its closest relative, Isoalcanivorax pacificus, suggesting it is a novel species.
- The strain contains specific fatty acids and lipid types, and features genes that indicate its potential for efficient oil degradation; it has been named Isoalcanivorax beigongshangi sp. nov

Glucose and lipid metabolism disorders are the core pathological mechanism of a variety of metabolic diseases, and the incidence of related diseases is increasing year by year, which seriously threatens human life and health. Traditional Chinese medicine with medicinal and edible properties refers to Chinese medicinal resources that have both medicinal and edible characteristics. Due to its safety and its health-promoting and medicinal functions, traditional Chinese medicine has received increasing attention in the development of functional health foods.
