“…Total phenolic content was determined by the Folin-Ciocalteu colorimetric method (Seon et al, 2021). After 50 μL of metabolites and 50 μL of Folin reagent (0.25 mol/L) were shaken for 3 min, 1 mL of 0.7 mol/L Na 2 CO 3 was added to react for 1 h. 200 μL of the reaction solution was taken out and the absorbance was measured at 750 nm.…”

Presently in order to excavate suitability of resources of lactic acid bacteria for fermentation of mandarin fish, a strain of lactic acid bacteria (LAB), which was cultivated from stinky mandarin fish via using traditional MRS medium (CMC 1-8), was firstly isolated and purified. Subsequently, it was discovered that the as-harvested LAB was recognized as Lactobacillus sakei subsp. sakei with assistance of technology of phenotypic identifying and 16S rRNA sequencing. Concurrently, relevant characteristics in aspects of growth curve, acid production capacity, temperature and salt tolerance of Lactobacillus sakei subsp. sakei were plainly investigated. Furthermore, the preliminary research on protease properties and biological properties was revealed. The results unfolded that the strain could grow and produce acid normally at 37 °C, and deliver a strong tolerance even under 3% NaCl at 12 °C, which could be significant sufficiently to satisfy the low-temperature and salty fermentation of mandarin fish. The best compatible temperature and pH value for protease production were at 70 °C and 9.0, respectively. Resultantly, the main metabolites, containing polyphenols, flavonoids and soluble polypeptides, performed a remarkable effect on scavenging abilities of 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 1,1-diphenyl-2-picrylhydrazine (DPPH) free radical and ferricyanide reducing ability, of which the IC 50 were 1.05, 6.87, and 4.62 mg/mL, respectively. And, the metabolites displayed partial inhibitory effects on Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Bacillus subtilis. Therefore, CMC 1-8 can potentially serve as a functional microorganism to directionally ferment mandarin fish.

“…Flavonoids function to improve blood circulation throughout the body and prevent blockages in blood vessels, reduce cholesterol content and reduce fat accumulation in blood vessel walls, reduce the risk of coronary heart disease, contain anti-inflammatory (anti-inflammatory), function as antioxidants, help reduce pain if bleeding or swelling occurs Janicsák et al (1999). The research results of Ho-Young Seon et al (2021), showed a high significance that there was a correlation between the content of flavonoids and polyphenols with free radical and antioxidant activity.…”

Humans can use specific secondary metabolites as antioxidants or medicinal raw materials. Each plant has different secondary metabolites and a unique structure. Similarly, secondary metabolites were found in sorghum (Sorghum bicolor L. Moench). This paper aims to describe the types, characteristics, and benefits of secondary metabolites found in sorghum plants. The results of phytochemical screening showed that sorghum contains several secondary metabolites, namely alkaloids, flavonoids, tannins, polyphenols, saponins, steroids, and terpenoids. Epidemiological studies show that consuming plants rich in polyphenolic compounds reduces the rate of heart disease, cancer, gastrointestinal tract, neurological disease, liver disease, atherosclerosis, and obesity. Flavonoids are one of the phenol groups. Phenolic compounds have potential antioxidant activity and some of them be more effective than vitamins C, E, and carotenoids. Antioxidants are believed to have a role in reducing oxidative stress which plays a role in the development of chronic degenerative diseases including heart disease, cancer, and premature aging. Alkaloids are a group of compounds containing aromatic nitrogen. Alkaloids in the health sector are used as anti-tumor, antipyretic (fever-reducing), anti-pain (analgesic), stimulating the nervous system, raising and lowering blood pressure, and fighting microbial infections.

The present study aimed to evaluate the role of bioactive components in Solanum nigrum fruit, its phytochemical screening, and in vivo antioxidant potential against liver injury. The HPLC analysis of an ethanolic extract of Solanum nigrum fruit revealed the presence of bioactive components that showed its significant in vitro antioxidant activity. Moreover, The Sprague Dawley rats were divided into four groups for in vivo analysis: G1 (negative control), G2 (positive control), G3 (rats receiving standard drug), and G4 (rats receiving Solanum nigrum fruit extract). The Solanum nigrum fruit reduced the level of liver enzymes, and bilirubin. An opposite trend was seen in the case of albumin, catalase, creatinine, and superoxide dismutase. Histology slides also showed the normal cell structure of hepatocytes. Conclusively, Solanum nigrum fruit bioactive components have the ability to reduce oxidative stress.
