In this study, water-soluble polysaccharide and fatty acids of Cordia myxa fruit harvested from the southwest of Iran were isolated and investigated. The extraction yield of water-soluble polysaccharide of C. myxa fruit (WSPCM) was 24.12%, and its experimental purity was 79.43%. The High Performance Liquid Chromatography results indicated that the WSPCM consisted of glucose, fructose, sucrose, maltose, ribose, maltitol, and maltoheptaose. The atomic absorption spectrometer analysis indicated that WSPCM was a rich source of Ca and Na. The dynamic light scattering results illustrated that the average particle size and zeta potential were 1510.7 nm and − 64.96, respectively. Fourier transform infrared spectroscopy revealed the presence of α and β-configurations in WSPCM. The total unsaturated and saturated fatty acids were 60.62% and 39.38%, respectively and oleic, palmitic, and linoleic were the main fatty acids. The WSPCM represented good antibacterial activities against both Gram-positive and Gram-negative pathogenic bacteria. Moreover, it showed a relatively good antioxidant activity. In conclusion, WSPCM could be introduced as a novel natural antioxidant and antibacterial substance in functional food.

在这项研究中，从伊朗西南部收获的Cordia myxa果实的水溶性多糖和脂肪酸被分离出来并进行了调查。粘纤梭菌水溶性多糖的提取得率果（WSPCM）为24.12％，其实验纯度为79.43％。高效液相色谱结果表明，WSPCM由葡萄糖，果糖，蔗糖，麦芽糖，核糖，麦芽糖醇和麦芽七糖组成。原子吸收光谱仪分析表明，WSPCM是钙和钠的丰富来源。动态光散射结果表明，平均粒径和ζ电势分别为1510.7 nm和-64.96。傅立叶变换红外光谱揭示了WSPCM中存在α和β构型。总的不饱和脂肪酸和饱和脂肪酸分别为60.62％和39.38％，其中主要的脂肪酸是油酸，棕榈酸和亚油酸。WSPCM对革兰氏阳性和革兰氏阴性致病菌均具有良好的抗菌活性。此外，它显示出相对较好的抗氧化活性。总之，WSPCM可以作为功能性食品中的新型天然抗氧化剂和抗菌物质引入。
