Analysis of the Functional Components of Four “Sanghuang”‐Like Species Using UPLC‐ESI‐MS/MS‐Based Widely Targeted Metabolomics and TCMSP Database

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.
“Sanghuang” is a rare, edible, medicinal macrofungus. However, various macrofungi that share similar appearances, habitats, and therapeutic effects with “Sanghuang” have been erroneously used in traditional folk medicine. As of date, metabolic differences among these “Sanghuang”‐like species have been unclear, impeding their commercial utilization ...

In Vitro Acaricidal Activity of Croton macrostachyus Leaf and Ricinus communis Seed Extracts Against Cattle‐Infesting Ticks (Rhipicephalus spp. and Amblyomma spp.)

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
Ticks are major ectoparasites of cattle and vectors of zoonotic and livestock diseases. Reliance on synthetic acaricides like diazinon has led to environmental concerns and rising resistance, prompting the search for ecofriendly alternatives. This in vitro study evaluated the acaricidal activity of Croton macrostachyus, Ricinus communis, and their ...

Facile (Z)‐Selective Synthesis of β,γ‐Unsaturated Ketones by a Silicon‐based Olefination Strategy

Angewandte Chemie International Edition, Volume 64, Issue 49, December 1, 2025.
A silicon‐based olefination strategy has been developed to access challenging (Z)‐configured β,γ‐unsaturated ketones from readily accessible branched vinyl silanes and acid chlorides. This method enables the straightforward synthesis of a broad variety of deconjugated ketones with high (Z)‐selectivity under mild conditions and provides a new ...

Sucrose Monoesters of Ricinoleic Acid and 12-Ketooleic Acid

The Journal of the Society of Chemical Industry, Japan, 1959
リシノール酸およびそれを酸化して得られる12-ケトオレイン酸のサッカロースモノエステルを合成して,その界面活性剤としての諸性状を明らかにするとともに,既に報告があるサッカロースモノステアレートおよびオレエートと,同一条件下における比較検討を行って,脂肪酸基の構造の差異によるその界面活性能の相違について研究を行った結果,(1)これら4種のエステルの表面張力,界面張力は各濃度においてほぼ同じであり,大きい差異はない。(2)浸透性は1%以下の濃度にあっては12-ケトオレエートが,1%にあってはリシノレートが大で,脂肪酸部に親水基を持つものが良好であり,ステアレート,オレエートと大きい差異を生じた。(3)起泡性は12-ケトオレエート>リシノレート>オレエート>ステアレートの順となり,特にステアレートは小さく,

Electrospun Fibers Containing Bio‐Based Ricinoleic Acid: Effect of Amount and Distribution of Ricinoleic Acid Unit on Antibacterial Properties

Macromolecular Materials and Engineering, 2015
AbstractNovel bio‐based and biodegradable electrospun membranes, containing bactericidal ricinoleic acid (RA) units either by copolymerization with butylene succinate (BS) units or by blending PRA and PBS homopolymers, are characterized in their chemical, thermal, mechanical and surface properties. In the blends E. coli and S.

Lignin‐Sourced Aromatics for Biodegradable Flexible Copolyesters Mimicking Poly(Butylene Adipate‐co‐ Terephthalate)

ChemSusChem, Volume 18, Issue 23, December 1, 2025.
In this study, two series of novel PBAT‐mimicking copolyesters are introduced by exploiting lignin‐based building blocks. This class of copolyesters exhibits good barrier properties and biodegradability, paving the way for terephthalate‐free, biodegradable, flexible copolyesters. Poly(butylene adipate‐co‐terephthalate) (PBAT) is an important commercial
