A computationally driven experimental search for polymorphs of 3-hydroxybenzoic acid confirmed the third form and small energy differences between polymorphs.

In this paper, the extraction of polyphenols from amaranth seed using a Box–Benhken design four factors—ultra-turrax speed, solid-to-liquid ratio (RSL), methanol concentration and time—were studied. There were two responses studied for model: total phenolic content (TPC) flavonoid (TFC). The factors which influenced most TPC TFC RSL, ultra-turrax speed. Twelve acids (rosmarinic acid, p-coumaric...

Bordetella sp. strain 10d metabolizes 4-amino-3-hydroxybenzoic acid via 2-hydroxymuconic 6-semialdehyde. Cell extracts from 4-amino-3-hydroxybenzoate-grown cells showed high NAD(+)-dependent 2-hydroxymuconic 6-semialdehyde dehydrogenase, 4-oxalocrotonate tautomerase, 4-oxalocrotonate decarboxylase, and 2-oxopent-4-enoate hydratase activities, but no 2-hydroxymuconic 6-semialdehyde hydrolase act...

Preservatives are chemical substances whose role is to protect medicinal products against harmful changes caused by microorganisms. They are added to sterile medicinal products, such as eye drops and multidose solutions for injections, as well as to non-sterile products, such as water oral solutions, creams, gels, suppositories and capsules with liquid content. The most commonly used preservati...

This study isolated, determined, and quantified plant growth inhibitors in Japanese chestnut (Castanea crenata Sieb. et Zucc), a deciduous species native to Japan and Korea. In laboratory assays, C. crenata leaves showed strong inhibition on germination and seedling growth of Echinochloa crus-galli (barnyardgrass), Lactuca sativa (lettuce), and Raphanus sativus (radish). Laboratory and greenhou...

dendrobium genus was reported to contain alkaloid, bibenzyl, fluorenone, phenanthrene, sesquiterpenoid, and phenolic acid, which have biological properties. our aim was to investigate the protective effect of an aqueous extract of dendrobium nobile lindl (dne) against cisplatin-induced acute kidney injury (aki). quantification of four phenolic acids (4-hydroxybenzoic, vanillic, syringic, and fe...
