“…Through pairwise comparison of samples in three groups, it was found that, no matter whether NAD, HAD or VFD is adopted, the main metabolite types of PCS are concentrated in classes such as lipids and amino acids. This finding is similar to the metabolite analyses results of P. ostreatus and P. citrinopileatus reported by Li et al [ 24 ]. However, further data analysis revealed that the amounts and contents of many metabolites were distinctly different between each group, indicating that drying methods can exert an important effect on metabolite formation.…”

Pleurotus citrinopileatus Singer (PCS) has attracted increasing attention as a raw material for medicine and food. Its quality is greatly affected by the accumulation of metabolites, which varies with the applied drying methods. In this study, we utilize an approach based on ultra-high-performance liquid chromatography/Q Exactive mass spectrometry (UHPLC-QE-MS) to reveal the metabolic profiles of PCS from three different drying methods (natural air-drying, NAD; hot-air-drying, HAD; vacuum freeze-drying, VFD). The results showed that lipids, amino acids and their derivatives were all important secondary metabolites produced during NAD, HAD and VFD treatments, with the key differential metabolites of PCS during drying including fifteen lipids and seven amino acids. Meanwhile, VFD was the best way for long-term preservation of dried PCS. Hot-drying methods, especially HAD, can improve the medicinal component of PCS. Furthermore, KEGG enrichment analysis highlighted 16 pathways and indicated that amino acid metabolism might be the key metabolite pathway for the PCS drying process. Our study elucidates the relationship between drying methods and metabolites or metabolic pathways of PCS to determine the mechanisms affecting the quality of PCS, and finally provides reference values for further development and application in functional food and medications.

“…Organic acids and soluble sugars, as indispensable contributors to fruit quality, affect fruit flavor and indirectly have both favorable and unfavorable effects on commercial fruit quality (Li et al 2023). Soluble sugars and organic acids are nutrients and key indicators of fruit crop quality, flavor, and ripeness.…”

Figs (Ficus carica Linn.) are a new generation of economic forest crops with high nutritional value. This study aimed to clarify the intrinsic association between organic acids and the quality of figs after introducing multispecies. The figs introduced in Shandong are rich in organic acids and contain a wide variety of highly concentrated bioactive compounds. A total of 24 organic acids were detected in this experiment, 13 of which were newly detected. Citric acid was the main organic acid in Shandong-introduced figs, accounting for 66% of the total acid on average. This was followed by malic and citric acids, accounting for 15.9% and 11.6%, respectively. The mean total phenolic, flavonoid, and soluble solid contents were 1.627 mg/g, 0.588 mg/g, and 16.217 °Brix, respectively. The fig cultivar Banane had the highest total organic acid content and high total phenolic and flavonoid contents. The results of the partial least squares regression showed that the regression coefficients of caffeic acid, ferulic acid, chicoric acid, p-hydroxybenzoic acid, and quinic acid on the total soluble solids were in the range of 0.194–0.279, favoring the accumulation of total soluble solids. Trans-aconitic acid, citric acid, cis-aconitic acid, pyruvic acid, and tartaric acid promoted the accumulation of total phenolics and flavonoids. The regression coefficients ranged from 0.200 to 0.310 for total phenolics and 0.233 to 0.290 for total flavonoids. The discovery of a close intrinsic association between organic acids and nutrients provides a new reference basis for screening good fig cultivars and their nutritional development.

“…The complete characterization of a compound is achieved with 2D-NMR [ 20 ]. Molecular networking is a tool used to identify and classify the similarity between metabolites [ 22 ]. This approach allows for the visual representation of the structural relationships among the natural constituents in crude extracts and further compares the tandem MS spectra to the publicly accessible spectral library for the rapid characterization and identification of known constituents [ 23 ].…”

Breonadia salicina (Vahl) Hepper & J.R.I. Wood is widely distributed throughout Africa. It is used ethnobotanically to treat various diseases. However, the metabolic profile of the Breonadia species is not well characterized and the metabolites that are responsible for the bioactivity of this plant remain unknown. Therefore, there is a need to determine the phytochemical and bioactivity profile to identify metabolites that contribute to the antidiabetic, anti-inflammatory and antiproliferation activity, including the genotoxicity and cytotoxic effects, of Breonadia salicina. The study is aimed at exploring the metabolomic profile antidiabetic, anti-inflammatory and antiproliferation activity, as well as the genotoxicity and cytotoxicity effects, of constituents of B. salicina. The compounds in the B. salicina extract were analyzed by ultra-performance liquid chromatography with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS), and the resultant data were further analyzed using a molecular networking approach. The crude stem bark and root extracts showed the highest antidiabetic activity against α-amylase at the lowest test concentration of 62.5 µg/mL, with 74.53 ± 0.74% and 79.1 ± 1.5% inhibition, respectively. However, the crude stem bark and root extracts showed the highest antidiabetic activity against α-glucosidase at the lowest test concentration of 31.3 µg/mL, with 98.20 ± 0.15% and 97.98 ± 0.22% inhibition, respectively. The crude methanol leaf extract showed a decrease in the nitrite concentration at the highest concentration of 200 µg/mL, with cell viability of 90.34 ± 2.21%, thus showing anti-inflammatory activity. No samples showed significant cytotoxic effects at a concentration of 10 µg/mL against HeLa cells. Furthermore, a molecular network of Breonadia species using UPLC-QTOF-MS with negative mode electrospray ionization showed the presence of organic oxygen compounds, lipids, benzenoids, phenylpropanoids and polyketides. These compound classes were differentially distributed in the three different plant parts, indicating the chemical differences between the stem bark, root and leaf extracts of B. salicina. Therefore, the identified compounds may contribute to the antidiabetic and anti-inflammatory activity of Breonadia salicina. The stem bark, root and leaf extracts of B. salicina yielded thirteen compounds identified for the first time in this plant, offering a promising avenue for the discovery of new lead drugs for the treatment of diabetes and inflammation. The use of molecular networking produced a detailed phytochemical overview of this Breonadia species. The results reported in this study show the importance of searching for bioactive compounds from Breonadia salicina and provide new insights into the phytochemical characterization and bioactivity of different plant parts of Breonadia salicina.
