研究的目的是研究超声波浸渍(U)对鼠尾草直接提取鼠尾草酸(CA)及其衍生物-鼠尾草酚(C)的影响,与均质化辅助浸渍(H)相比。结果表明,超声浸渍过程(U)可以获得富含鼠尾草酸(CA)和鼠尾草酚(C)的浸渍液,还含有迷迭香酸(RA),总多酚,和植物色素,并显示抗氧化性能(DPPH测试)。在U和H之间,从鼠尾草中提取成分到浸油中的效率没有明显差异,与H相比,在大多数情况下使用超声会导致C的提取更多,并且从鼠尾草中提取到浸渍液中的色素的提取更少。在使用较高功率(320W)的浸渍U60分钟后,可以获得浸渍液中CA(147.5mg/100g)和C(42.7mg/100g)的最高同时含量。测定的化合物的量还取决于用于分析的甲醇(甲醇;70%甲醇)的浓度。浸渍U是一个简单的,安全,获得活性物质的“绿色方法”,随着步骤数量的减少,启用CA和C的有趣申请表,例如,用于食品或化妆品。
The aim of the study was to examine the effect of ultrasonic maceration (U) on the extraction of carnosic acid (CA) and its derivative-carnosol (C)-directly from sage into fish oil, compared to homogenization-assisted maceration (H). It was shown that the ultrasonic maceration process (U) allowed for obtaining a macerate enriched in carnosic acid (CA) and carnosol (C), also containing rosmarinic acid (RA), total polyphenols, and plant pigments, and showing antioxidant properties (DPPH test). There was no unequivocal difference in the efficiency of extracting ingredients from sage into the oil macerate between U and H, with the use of ultrasound in most cases resulting in a greater extraction of C and less extraction of pigments from sage into the macerate than in H. The highest simultaneous contents of CA (147.5 mg/100 g) and C (42.7 mg/100 g) in the macerate were obtained after 60 min of maceration U when using a higher power (320 W). The amount of determined compounds also depended on the concentration of methanol (methanol; 70% methanol) used for the analysis. The maceration U is a simple, safe, \"green method\" of obtaining active substances, with a reduced number of steps, enabling an interesting application form of CA and C, e.g., for food or cosmetics.
