“…The antioxidant property of fruit juices is accredited to the redox activity of the polyphenols allowing them to work as a reducing agent and help in the metal chelation process along with the reduction of the hydrogen‐donating molecules (Aadil, Zeng, et al, ). Bound phenolic compounds in fruits are reported to be embedded in the cell wall, whereas soluble phenolics are stored in the vacuole (Gan et al, ). Ultra‐sonication results in rupturing of cell wall, therefore, releasing the bound and soluble phenolic compounds in fruit juices.…”

Apple-grape juice blend (50:50) were subjected to blanching (thermal), high temperature-short time (72°C: 15 s), ultra-sonication (5 & 10 min), thermo-ultrasound (5 min, 40°C; 10 min, 40°C), and thermo-ultrasound (5 min, 50°C; 10 min, 50°C) and were compared to control treatment for the antioxidant indices. Furthermore, one best treatment each from ultra-sonication (10 min), thermo-ultrasound at 40°C (5 min), and thermoultrasound at 50°C (5 min) was analyzed through high performance liquid chromatography diode array detector (HPLC-DAD) for the quantification of individual phenolic acids, flavanols, stilbenes, and anthocyanins. Polyphenolic profile (HPLC-DAD) of apple-grape juice blends treated with ultra-sonicated (10 min), thermo-ultrasound (5 min; 40°C), and thermo-ultrasound (5 min: 50°C), resulted in identification of 23 polyphenols (9 phenolic acids; 6 flavanols; 1 stilbene; 7 anthocyanins). Results of HPLC characterization revealed a significant (p < .05) effect of tested treatments on all the polyphenols. Among phenolic acids, chlorogenic acid was observed to be highest (422.12 mg/L) in ultra-sonicated juice blend (T U-10 :10 min) followed by caftaric, gallic, syringic, vanillic, caffeic, ferulic, and cinnamic acids. While, content of resveratrol (stilbene), epigallocatechin gallate (flavanol), and Malvidin 3, 5-diglucoside (anthocyanin) were also found to be maximum (33.08, 386.32, and 70.25 mg/L, respectively) in ultra-sonicated (10 min) apple-grape juice blend samples. Keeping in view the polyphenolic profile and consumer preferences, ultra-sonication could be employed industrially as an alternative substitute of thermal processing techniques to enhance the quality of apple-grape juice blend.Practical application: For years, several nonthermal techniques are used for the preservation and quality improvement of fresh juices mainly by preventing the microorganisms and enzymes. Among these technique, single nonthermal treatment has a capacity to reduce the amount of microorganism and enzymes while a combined technique such as thermo-ultrasound has a better effect than single treatment, which have been investigated in this study. Therefore, this article would encourage the juice industrialists by applying these techniques for commercialization of juice and juice products in a more effectual manner.

“…While the term "phenolic compounds" includes a broad group of molecules containing at least one phenol unit, different other subgroups, such as flavonoids, tannins, and phenolic acids, among others, can be defined based on their chemical structures [28]. In the current work, the content of major phytochemical groups from B. speciosa stem bark extracts was evaluated while using spectrophotometric methods and are summarized in Table 1.…”

Bridelia species have been used in traditional African medicine for the management of diverse human ailments. In the current work, the detailed phytochemical profiles of the extracts of the stem bark of B. speciosa were evaluated and the antioxidant and enzyme inhibitory properties of the extracts were assessed. The anti-bacterial and anti-mycotic effects of the extracts were evaluated against selected pathogen strains. Additionally, the anti-proliferative effects were studied on the liver cancer HepG2 cell line. Finally, the putative protective effects were assessed on isolated rat liver that was challenged with lipopolysaccharide (LPS). The results revealed the presence of 36 compounds in the ethyl acetate extract, 44 in the methanol extract, and 38 in the water extract. Overall, the methanol extract showed the highest antioxidant activity, particularly in LPS-stimulated rat liver. Additionally, this extract exerted the highest antimycotic effect on C. albicans, whereas the water extract showed a promising anti-proliferative effect on liver cancer HepG2 cells. The methanol extract was also the most active as enzyme inhibitor, against acetylcholinesterase and butyrylcholinesterase. The current study appraises the antioxidant and enzyme inhibition properties of B. speciosa methanol extract and showed that this specie could be a promising source of biologically active phytochemicals, with potential health uses.

“…Phenolic compounds are ubiquitously distributed metabolites in higher plants [16,44], and they play an important role in plant defenses against biotic and abiotic stresses [45], particularly the phytopathogenic fungi [17,46]. Moreover, numerous phenolic acids and phenolic-rich extracts exhibited high inhibitory effects on the radial growth of fungi [18,47].…”

The Antifungal Activity of Gallic Acid and Its Derivatives against Alternaria solani, the Causal Agent of Tomato Early Blight

et al. 2020

Tomato (Solanum lycopersicum L.) is among the most important vegetable crops worldwide. Early blight disease, caused by Alternaria solani, is a destructive foliar disease of tomato and other Solanaceae species. Herein, we investigated the in vitro antifungal properties of gallic acid and two of its derivatives (syringic and pyrogallic acids) against A. solani during 2019 and 2020 seasons. The physiological and biochemical effects of these compounds on infected tomato plants were also investigated using the whole plant bioassay. The in vitro investigation showed that all tested compounds showed fungistatic action and inhibited the mycelial radial growth of A. solani in a dose-dependent manner. In two separate pot-experiments, those compounds efficiently suppressed the development of the disease symptoms and area under disease progress curve (AUDPC), without any phytotoxic effects on the treated tomato plants. Additionally, all tested compounds positively enhanced the biochemical traits of treated plants including the chlorophyll content, the total soluble phenolics, the total soluble flavonoids, and the enzymatic activities of catalase, peroxidase, and polyphenol oxidase during 2019 and 2020 seasons. Moreover, the treatment with gallic acid and its derivatives significantly increased all yield components of A. solani-infected tomato plants such as the total number of flowers and fruits, and the fruit yield for each tomato plant in both experiments. Considering the fungitoxicity of phenolic acids against A. solani with no phytotoxicity on treated tomato plants, we believe that gallic acid and its derivatives might be a sustainable eco-friendly control strategy to reduce the usage of chemical fungicides partially or entirely against A. solani particularly, and fungal diseases in general.
