Yellow pigments, fomitellanols A (1a) and B (2a), and drimane-type sesquiterpenoid ethers of isocitric acid, cryptoporic acids P (3) and Q (4), have been isolated from the fruiting bodies of Fomitella fraxinea (Polyporaceae). Their structures were established by a combination of extensive NMR spectroscopy and/or X-ray crystallographic analyses, and their biological activity against COX-1, COX-2, and 5-LO was investigated.

This study is the first to explore the effects of the novel yellow pigment monascinol (Msol) from red mold rice (RMR) on reducing body fat and to compare its effects with those of monascin (MS) and ankaflavin (AK). In a high-fat diet-induced rat model, different doses of RMR fermented rice (RL, RM, RH) and purified Msol, MS, and AK were administered over an 8-week period. The results showed that all treatment groups significantly reduced body weight and fat mass.

Objective: This study aimed to evaluate the in vitro effects of coffee exposure on the color and roughness of conventional and bulk-fill resin composites, with and without surface pre-reacted glass-ionomer (S-PRG) filler.

Methodology: Forty-eight cylindrical samples (Ø6 mm × 2 mm) were prepared and categorized as follows (n = 12 per group): conventional nano-hybrid (Tetric N-Ceram, Ivoclar); nano-hybrid with S-PRG filler (Beautifil II, Shofu); bulk-fill (Tetric N-Ceram Bulk Fill, Ivoclar); and bulk-fill with S-PRG filler (Beautifil Bulk Restorative, Shofu). The samples were assessed for surface roughness (Ra, μm), color coordinates (CIE Lb), and overall color change (ΔE, ΔE).

Soybean has outstanding nutritional and medicinal value because of its abundant protein, oil, and flavonoid contents. This crop has rich seed coat colors, such as yellow, green, black, brown, and red, as well as bicolor variants. However, there are limited reports on the synthesis of flavonoids in the soybean seed coats of different colors.

Integrative Targeted Metabolomics and Transcriptomics Reveal the Mechanism of Leaf Coloration in 'Sakimp005'.

Int J Mol Sci

December 2024

Research and Development Center of Landscape Plants and Horticulture Flowers, Yunnan Engineering Research Center for Functional Flower Resources and Industrialization, Southwest Research Center for Engineering Technology of Landscape Architecture (State Forestry and Grassland Administration), College of Landscape Architecture and Horticulture Sciences, Southwest Forestry University, Kunming 650224, China.

One of the most important characteristics of ornamental plants is leaf color, which enhances the color of plant landscapes and attracts pollinators for reproduction. The leaves of 'Sakimp005' are initially green, then the middle part appears yellow, then gradually become white, while the edge remains green. In the study, leaves of 'Sakimp005', in four developmental stages (S1-G, S2-C, S3-C, and S4-C), were selected for the determination of pigment content, chromaticity values, integrative metabolomics, and transcriptomics analyses.
