“…ROS are highly unstable and damage cells by attacking intracellular proteins, nucleic acids, and cell membranes (Min et al, 2022). To maintain homeostasis, they are mostly eliminated by defense mechanisms, such as the antioxidant defense system, which includes glutathione peroxidase (GPx) catalase (CAT), and superoxide dismutase (SOD) (Wang, 2022;Jóźwiak & Politycka, 2019). However, when the rate of ROS generation exceeds that of elimination, homeostasis is perturbed, resulting in cellular damage and the loss of normal function, which can cause diseases like arteriosclerosis and cardiovascular disease as well as accelerated aging (Wilmes et al, 2020;Hao et al, 2022).…”
The purpose of this study is to investigate the effect of bioconverted Oenanthe javanica extract (BOE) using Lactiplantibacillus plantarum SM4 on production of bioactive compounds. Response surface methodology was used to determine the optimal ultrasound-assisted extraction conditions including the extraction time, extraction temperature, and ethanol concentration for the enhancement of bioactive compounds production. The predicted optimum UAE conditions were extraction time of 26.0 min, extraction temperature of 92.8 °C, and 59.9% ethanol, respectively, and 5.14 mg GAE/g DM of TPC and 0.59 mg QE/g DM of TFC were produced under the optimum condition. Then, O. javanica extraction (OJE) has been bioconverted by using L. plantarum SM4 to increase the bioactive compounds. In HPLC-mass spectrometry analyses, higher concentration of p-coumaric acid was identified in BOE than in OJE, and chlorogenic acid in OJE was converted to quinic acid, confirming an increase in bioactive compounds by bioconversion. Thus, we have concluded that optimization of UAE and the BOE is an effective process for enhancement bioactive compounds from O. Javanica and this finding provides a scientific basis of bioactive compounds in natural product can be utilized as food, cosmetics, and pharmaceutical materials from BOE.
