“…The iron-reducing ability of phenolic acids increases with increasing concentration. Compared with -COOH, -CH=CHCOOH can enhance the antioxidant activity of phenolic acids (Gao et al, 2022). After treatment with EDTA- Fe, ferric citrate and ferric gluconate, the contents of vanillic acid, protocatechuic acid, gentisic acid and p-hydroxybenzoic acid were all increased, similar to the results of Shi Pengbao's study (Shi et al, 2017).…”

In order to explore the effect of different irons on the fruit quality of wine grapes, as well as the phenolic acids and proanthocyanidins of the peel, "Cabernet Sauvignon" was taken as the research object. Ferrous sulfate, EDTA-Fe, ferric citrate, ferric gluconate and ferric sugar alcohol were sprayed between the coloring periods, and the foliar sprayed water was used as the control. The results showed that foliar spraying of iron would increase the fruit sugar-acid ratio and 100-grain weight; iron spraying would up-regulate the content of phenolic acid monomers, among which EDTA-Fe and ferric citrate had significant up-regulating effects, but all iron treatments had a significant effect on the increase. The content of caffeic acid and chlorogenic acid was down-regulated; the content of proanthocyanidin monomer was up-regulated by iron spraying, and the content of proanthocyanidin monomer was significantly up-regulated by ferric citrate treatment. Foliar spraying of ferric citrate not only balanced the sugar-acid ratio of the fruit, but also increased the content of phenolic acid and proanthocyanidin in the grape peel, which further improved the quality of the grapes and helped to increase the flavor of the wine.

“…Flavonoids are the material basis for Sophorae Flos , used to treat hemorrhage ( Sachetto et al, 2018 ), exuberant liver fires ( Wu et al, 2017 ), and cardiovascular and cerebrovascular diseases ( Annapurna et al, 2009 )—and are also used as quality control indicators ( Chinese Pharmacopoeia Commission C.P, 2020 ). Flavonoids and phenolic acids are outstanding antioxidants because of their phenolic hydroxyl structures that can bind to free radicals ( Gao et al, 2022 ). Traditionally, flowers and flower buds have been used for this purpose.…”

Sophora japonica L. is widely consumed in China because of its medicinal and nutritional value. Its quality is greatly affected by the accumulation of metabolites, which varies with the stage of flower development. However, changes in the characteristics of the secondary metabolites during flower maturity remain unclear. Ultra-high-performance liquid chromatography coupled with electrospray ionization-triple quadrupole-linear ion trap mass spectrometry (UPLC–ESI–QTRAP–MS/MS) revealed dynamic changes in the secondary metabolites of S. japonica during the five flower-maturity stages. We monitored 331 metabolites and screened 164. The differential metabolites showed seven trends during flower maturation, with flavonoids and phenolic acids having the most varied expressions. Flower buds (S2–S3) are rich in flavonoids and are thus suitable for use in high-quality medicine or industrial extraction. Our study provides an empirical basis for the informed harvesting of S. japonica based on its mode of utilization.

“…HBAs have a C6-C1 main structure derived directly from benzoic acid and include p-HBAs such as proto-catechuic, vanillic, gallic, and syringic acids, while HCAs are aromatic compounds with a side chain of three carbon atoms (C6-C3), and they are represented by coumaric, caffeic, ferulic, and synaptic acids. PA are found in vegetables, and specific HBAs are abundantly found in oilseeds, cereals, coffee beans, cowpeas, blackcurrants, raspberries, skins and seeds of pumpkins, and blackberries, while HCAs are found in coffee beans, cherries, grains, peaches, spinach, citrus fruits, plums, tomatoes, potatoes, and almonds [ 142 , 144 , 145 ].…”

Transdermal delivery devices and wound dressing materials are constantly improved and upgraded with the aim of enhancing their beneficial effects, biocompatibility, biodegradability, and cost effectiveness. Therefore, researchers in the field have shown an increasing interest in using natural compounds as constituents for such systems. Plants, as an important source of so-called “natural products” with an enormous variety and structural diversity that still exceeds the capacity of present-day sciences to define or even discover them, have been part of medicine since ancient times. However, their benefits are just at the beginning of being fully exploited in modern dermal and transdermal delivery systems. Thus, plant-based primary compounds, with or without biological activity, contained in gums and mucilages, traditionally used as gelling and texturing agents in the food industry, are now being explored as valuable and cost-effective natural components in the biomedical field. Their biodegradability, biocompatibility, and non-toxicity compensate for local availability and compositional variations. Also, secondary metabolites, classified based on their chemical structure, are being intensively investigated for their wide pharmacological and toxicological effects. Their impact on medicine is highlighted in detail through the most recent reported studies. Innovative isolation and purification techniques, new drug delivery devices and systems, and advanced evaluation procedures are presented.
