背景:藻类提取物在农业中被用作生物肥料而不是化学肥料。Further,众所周知,藻类具有高含量的植物激素,比如赤霉素,水杨酸,脱落酸,和油菜素类固醇.
目的:本研究的主要目的是使用磁性可回收离子液体(IL)从马尾藻中提高提取率并同时提取植物生长所需的激素。
方法:在本研究中,用乙酸进行酸性消化,然后用氢氧化钾进行碱性消化。
结果:结果显示离子液体对萃取产率的影响为266%。使用高效液相色谱(HPLC)方法分析提取的植物激素。赤霉素含量高,水杨酸,脱落酸,和油菜素类固醇在改进藻类提取中的应用表明,海藻提取物可以作为环境友好的液体生物肥料代替化学肥料,在有机农业可持续农业中发挥关键作用。此外,离子液体的可恢复性八倍,浸出可忽略不计,证明了引入的程序是具有成本效益的。
结论:报道的藻类提取程序通过使用酸性/初级离子液体环境来改进。该过程是经济的,因为离子液体由于其磁性特征而具有简单的可重用性。
BACKGROUND: Algae extracts are utilized as biofertilizers instead of chemical ferti-lizers in agriculture. Further, algae are known to possess a high content of plant hormones, such as gibberellin, salicylic acid, abscisic acid, and brassinosteroids.
OBJECTIVE: The main objective of this study was to increase the extraction yield and simulta-neously extract hormones required for plant growth from Sargassum swartzii using Magnetic recoverable ionic liquid (IL).
METHODS: In this study, extraction was performed by acidic digestion with acetic acid and then alkaline digestion with potassium hydroxide.
RESULTS: The results showed the ionic liquid effect in extraction yield by 266 percent. The extracted phytohormones were analyzed using high-performance liquid chromatography (HPLC) methods. High levels of gibberellin, salicylic acid, abscisic acid, and brassinosteroids in improved algae extraction showed that seaweed extract could be used as environmentally friendly liquid bio-fertilizers to replace chemical fertilizers and could play a crucial role in organic farming for sustainable agriculture. Additionally, the recoverability of ionic liquid eight times with negligible leaching proved the introduced procedure to be cost-effective.
CONCLUSIONS: The reported procedure for algae extraction improved by using an acidic/primary ionic liquid environment. This procedure is economical because of the simple reusability of ionic liquid due to its magnetic features.
