This study determined (1) phytochemical and antioxidant properties of moringa (Moringa oleifera Lam.) seed extract obtained by Naviglio's method; (2) antimicrobial activity; and (3) immunostimulant properties using Longfin yellowtail leukocytes. The results by Fourier Transform Infrared (FTIR) spectroscopy showed that moringa seed extract (MoSE) contained stretching vibrations of -OH, C-H, H-C=C-H, C-N, and C=O groups associated with free fatty acids and phytochemical molecules, whose profile included phenols, flavonoids, tannins, alkaloids and leucoanthocyanins. The seed extract demonstrated high antioxidant capacity and antibacterial activity against Vibrio parahaemolyticus and Aeromonas hydrophila. Moringa oleifera seed extract had no cytotoxic effects on fish peripheral blood leukocytes and enhanced immune parameters, such as respiratory burst activity, nitric oxide production, superoxide dismutase and catalase activities. In conclusion, MoSE obtained by Naviglio's technique was rich in phytochemical compounds with high antioxidant capacity, effective antibacterial activity and enhanced immune parameters in Longfin yellowtail leukocytes.

辣木 (Moringa oleifera) 种子提取物对长鳍鰤 (Seriola rivoliana) 外周血白细胞的抗菌和免疫调节活性

本研究确定了 (1)通过 Naviglio 方法获得的辣木 ( Moringa oleifera Lam.) 种子提取物的植物化学和抗氧化特性;(2) 抗菌活性;(3) 使用 Longfin 黄尾白细胞的免疫刺激特性。傅里叶变换红外 (FTIR) 光谱的结果表明,辣木种子提取物 (MoSE) 包含与游离脂肪酸和植物化学分子相关的 -OH、CH、HC=CH、CN 和 C=O 基团的伸缩振动,其谱包括酚类、黄酮类、单宁、生物碱和无色花青素。种子提取物显示出对副溶血弧菌嗜水气单胞菌的高抗氧化能力和抗菌活性。辣木种子提取物对鱼外周血白细胞没有细胞毒性作用,并增强免疫参数,如呼吸爆发活性、一氧化氮产生、超氧化物歧化酶和过氧化氢酶活性。总之,通过 Naviglio 的技术获得的 MoSE 富含植物化学化合物,具有高抗氧化能力、有效的抗菌活性和增强的 Longfin 黄尾白细胞免疫参数。
