摘要
本研究旨在通过制备一种山奈酚磷脂复合物（KA-PC）来提高山奈酚（KA）的溶解度，该复合物可用于防止大豆油变质。KA-PC 是通过溶剂蒸发法制备的，并通过傅立叶变换红外光谱（FTIR）、数显显微镜（DSC）和 X 射线衍射（XRD）对其进行了表征。此外，还将 KA-PC 添加到大豆油中，并测定了过氧化值和酸值。结果表明，KA-PC 提高了 KA 在水和正辛醇中的溶解度。几种表征方法确定 KA-PC 为无定形结构。KA-PC 清除 DPPH 自由基和 ABTS 自由基的速率高于 KA。贮存 15 天后，KA-PC 大豆油的过氧化值约为 17.35 mmol/kg，明显低于 KA 组（约 29.70 mmol/kg）。
Preparation, characterisation and evaluation of kaempferol phospholipid complex and its application in preventing the deterioration of soybean oil.
This study aims to improve the solubility of kaempferol (KA) by preparing a kaempferol phospholipid complex (KA-PC), which can be applied to prevent soybean oil from spoilage. KA-PC was prepared by solvent evaporation and characterised by FTIR, DSC, and XRD. Furthermore, KA-PC was added to soybean oil and the peroxide value and acid value were determined. The results showed that KA-PC improved the solubility of KA in both water and n-octanol. Several characterisation methods identified KA-PC as an amorphous structure. The rate of scavenging DPPH free radical and ABTS free radical of KA-PC was higher than that of KA. After 15 days of storage, the peroxidation value of the soybean oil of KA-PC was about 17.35 mmol/kg, which was significantly lower than that of the KA group (about 29.70 mmol/kg) The results help to prepare insoluble compounds into phospholipid complex (PC) and expand their application in food preservation.
期刊介绍：
The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds.
The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal.
Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
