“…On the day of harvest, there was no difference ( P < 0.05) in anthocyanins content and the total phenolic content (TPC) ( Supplementary Figure 1 ) according to the drainage conditions, but a significant difference in antioxidant activity was observed. The antioxidant activity of fruit has been reported to indicate storability in early harvest stages ( Oz et al., 2016 ) and can be decided by the secondary metabolites ( Park et al., 2020 ). There were significant differences in DPPH free-radical scavenging activity, expressed as RC 50 value, on harvest time ( P < 0.05) ( Figure 3C ).…”

“…Especially, fruit ripening results in fluctuation in the concentrations of specific VOCs such as aldehydes, alcohols, and esters ( Porta and Rocha-Sosa, 2002 ; Lv et al., 2014 ; Xu et al., 2017 ). As strawberry are vulnerable to mechanical injury, water loss, and fungi-caused decay, it has been recognized as one of the most perishable and delicate fruits ( Giampieri et al., 2012 ; Hashmi et al., 2013 ; de Souza et al., 2014 ; Neri et al., 2015 ; Park et al., 2020 ). Its quality is fluctuated and can be determined by color, texture, and chemical composition, e.g.…”

The metabolome of strawberries at harvest determines their storage capacity. Therefore, dynamics of volatile production during storage of strawberry cultivated under diverse drainage ratios, T1 (12.0%), T2 (25.3%), T3 (36.4%), and T4 (56.5%), were evaluated. Among the various non-target VOCs analysis, there were some groups including aldehydes, esters, and furans occupied over 5% with exhibiting high coefficient of determination (R2) following the days after storage (DAS). Aldehydes content decreased over the storage period, while the esters (methyl butanoate, methyl hexanoate, ethyl hexanoate, and benzyl acetate) and furanones (furaneol and mesifuran) were increased as representing aroma compounds in strawberry ripening. Even on the same day, it was investigated that the release of VOCs linked to fruit decay was delayed in the groups (T1 and T2) that were given relatively little water compared to T3 and T4. The hexanal and ethyl hexanoate as an over-ripened signal showed a rapid increase from 4 DAS to 5 DAS in T3 and T4, respectively, while T1 and T2 showed significant increase from 5 DAS to 6 DAS. Relatively slower over-ripening tendency of T1 and T2 was supported by changes of firmness, total soluble solid content, anthocyanin content, and antioxidant activity during storage. T1 and T2 showed higher antioxidant activity at the harvest time and lower anthocyanin accumulation than T3 and T4. The present study elucidated that the preharvest drainage changes during cultivation was involved in fruit quality during strawberry storage. Besides, volatilomics analysis depicted that T2 as an optimal ratio, could delay the occurrence of stress and senescence, and guaranteed the strawberry yield. In conclusion, this study provided evidence that the practical application of drainage ratios could improve horticultural product quality even with low water use and VOCs might be considered an early indicator for strawberry fruit shelf-life.

“…The DPPH radical scavenging activity was assessed using the DPPH decolorization method with some modifications, as per MJ Park, DH Ryu, JY Cho, DG Lee, JN Lee and Y-H Kang [ 27 ]. Before the experiment, DPPH powder was dissolved in ethanol to a concentration of 0.2 mM, and its absorbance was adjusted to 1.00 ± 0.05.…”

Background Atopic dermatitis (AD) is a chronic inflammatory condition characterized by the accumulation of reactive oxygen species and the expression of inflammatory factors. Regarding its anti-atopic activity, numerous traditional medicinal materials and secondary metabolic products play pivotal roles in modulating the associated mechanisms. Methods This study aimed to utilize Salvia miltiorrhiza Bunge (SMB) as an anti-AD source. In-vitro activity assessments and qualitative and quantitative analyses using UPLC-TQ-MS/MS and HPLC-DAD were conducted in two cultivars (‘Dasan’ and ‘Kosan’). Statistical analysis indicated that the profiles of their secondary metabolites contribute significantly to their pharmacological properties. Consequently, bio-guided fractionation was undertaken to figure out the distinct roles of the secondary metabolites present in SMB. Results Comparative study of two cultivars indicated that ‘Dasan’, having higher salvianolic acid A and B, exhibited stronger antioxidant and anti-inflammatory activities. Meanwhile, ‘Kosan’, containing higher tanshinones, showed higher alleviating activities on anti-AD related genes in mRNA levels. Additionally, performed bio-guided fractionation re-confirmed that the hydrophilic compounds of SMB can prevent AD by inhibiting accumulation of ROS and suppressing inflammatory factors and the lipophilic components can directly inhibit AD. Conclusions SMB was revealed as a good source for anti-AD activity. Several bioactive compounds were identified from the UPLC-TQ-MS/MS and different compounds content was linked to biological activities. Characterization of these compounds may be helpful to understand differential role of secondary metabolites from SMB on alleviation of AD.

“…It also carries one hydroxyl group at the 4 -position of B-ring [1]. Pg processes a wide range of biological activity including antioxidant [1], anti-inflammatory [2], anti-hyperglycemic [3], antiobesity [4], antidiabetic [5], neuroprotective [6], and anticancer activity [7]. Several physicochemical or physiological instabilities, such as physiologic pH, temperature (37 • C), oxygen, salt, enzymes, etc., limit the therapeutic effect of Pg [8].…”

Pelargonidin-3-O-glucoside (Pg) is a well-known anthocyanin derivative possessing potential biological activity. Nonetheless, the bioactivity of Pg is limited due to instability in the physiological environment. Functionalized nanoliposomes using chitosan and/or pectin coating is an excellent carrier system for nanoencapsulation of food bioactive compounds such as Pg. Therefore, this study aimed to investigate the protective effect of Pg-loaded pectin–chitosan coated nanoliposomes against palmitic acid (PA)-induced hepatocytes injury in L02 cells. Firstly, Pg-loaded pectin–chitosan coated nanoliposomes were characterized using the DLS, HPLC, TEM, and cellular uptake study in L02 cells. Thereafter, we assayed the protective effect against PA-induced lipotoxicity, ROS and O2•− generation, mitochondrial dysfunction (MMP), and GSH depletion. Results showed that Pg-loaded nanoliposomes significantly reduced the PA-induced L02 cells toxicity via suppressing ROS production, O2•− generation, MMP collapse, and GSH reduction, whereas the free-Pg samples were not effective. On the contrary, the chitosan and/or pectin coated nanoliposomes showed higher results compared to coating-free nanoliposomes. Altogether, the results of our study ensured that Pg-loaded pectin–chitosan coated nanoliposomes was capable of reducing PA-induced hepatocytes injury. Thus, pectin–chitosan coated nanoliposomes can be useful for hepatocellular delivery of hydrophilic compounds with greater biological activity.
