Article Title: Analysis of the Antioxidant Composition of Low Molecular Weight Metabolites from the Agarolytic Bacterium Alteromonas macleodii QZ9-9: Possibilities for High-Added Value Utilization of Macroalgae

doi: 10.3390/antiox11101977

Figure Lengend Snippet: Kinetics of DPPH scavenging activity of fermentation products from two culture periods during the reaction time of 1 h, ( A ) the period of 0 h to 50 h, and ( B ) the period of 50 h to 100 h. ( C ) DPPH scavenging activity of fermentation products during the culture of strain QZ9-9 after 1 h reaction. Note: The reaction time refers to the time consumed by the combination reaction between fermentation products and DPPH solution.

Article Snippet: According to the results of the composition analysis of the molecular weight ≤3 kDa, the maculosin was selected to vitrify the antioxidant activity by the method of the DPPH free radical scavenging experiment (the details are presented in the ), which was purchased from Shanghai Apeptide Co., Ltd., Shanghai, China.

Techniques: Activity Assay

Article Title: Assessment of Cosmetic Properties and Safety of Use of Model Washing Gels with Reishi, Maitake and Lion’s Mane Extracts

doi: 10.3390/molecules27165090

Figure Lengend Snippet: Kinetics of the absorbance changes in DPPH • solutions in the presence of water extract of Maitake, Lion’s Mane and Reishi. Values are the mean of three replicate determinations Negative control: ethanolsolution (1000 µg/mL). Positive control: ascorbic acid solution (1000 µg/mL).

Article Snippet: Moreover, DPPH free radical scavenging capacities were determined, which proved to be better for Lion’s Mane (2.85 μmole TE/g) than Maitake (1.75 μmole TE/g) [ ].

Techniques: Negative Control, Positive Control
