Extraction of Condensed Tannins from Branchlets of Casuarina glauca [PDF]

, 2005
探讨了对粗枝木麻黄(Casuarinaglauca)小枝多酚(Polyphenols)和缩合单宁(Condensedtannins)的适合提取条件.为确保样品中的多酚和缩合单宁的含量不被低估,含有1.0%HCl的7:3的丙酮水提取液是合适的提取溶剂.它能抑制以共价键结合的蛋白质和纤维素结合态的缩合单宁在样品处理过程中形成和在此酸性条件下对形成的复合物有一定的溶解,能提取出最大量的可溶态的多酚和缩合单宁.同时通过3次以上的提取,样品颗粒大小对可溶性多酚和缩合单宁的影响不显著 ...

Waste Adsorbent Valorization of Biopolymer‐Modified Zn–Fe Layered Double Hydroxides for Crystal Violet Removal and Enhanced Nonenzymatic Urea Detection

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
This graphical abstract illustrates the synthesis of Zn–Fe LDH composites with biopolymers (chitosan, cellulose, and carrageenan) for the efficient removal of crystal violet dye. The resulting spent adsorbents are subsequently repurposed for electrocatalytic urea detection, demonstrating a sustainable, circular approach to wastewater treatment and ...

The mechanisms of condensed tannins inhibit Pediococcus pentosaceus

Chemical and Biological Technologies in Agriculture
Background The antibacterial mechanisms of action of condensed tannins (CTs) obtained from tea are well known. However, the antibacterial mechanism of CTs from legumes, such as sainfoin, against to Pediococcus pentosaceus was still unclear.

Gene expression and metabolic variability in fungus‐resistant PIWI (‘Pilzwiderstandsfähig’) grape cultivars

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5841-5850, 15 August 2026.
Abstract BACKGROUND Fungus‐resistant PIWI (Pilzwiderstandsfähig) grape cultivars are promising for reducing pesticide inputs in viticulture, but their enological potential is still poorly characterized. We performed a pilot, single‐vintage study integrating berry gene expression and phenolic composition in five Italian red PIWI cultivars (Cabernet ...

Valorization of fruit pits from Prunus laurocerasus and Prunus cerasifera as agro‐food byproducts: Bioactive properties and safety assessment for potential food additive applications

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 6002-6014, 15 August 2026.
Abstract BACKGROUND Food additives are widely used to extend the shelf life of foods and maintain their quality. In this study, the potential of Prunus laurocerasus and Prunus cerasifera fruit pits (endocarp and seed) as food additives was investigated in terms of cytotoxicity, antigenotoxicity, antioxidant activity, enzymatic anti‐browning, and urease
