“…For the determination of the phenolic content (TPC, TFC, and TCT) and for the antioxidant potential (DPPH, FRAP, ABTS, RPA, FICA, OH-RSA, and TAC), the analyses were carried out according to the methods employed by Suleria et al, 61 Subbiah et al, 54 and Chen et al 62 with a few modifications. Absorption data were measured using a Multiskan GO microplate photometer (Thermo Fisher Scientific Inc., Waltham, MA, USA).…”

Sweet cherries ( Prunus avium L.) are popular fruits around the world with a high nutritional value and abundant phenolic compounds. Phenolic compounds of cherries contribute to positive health benefits. This study aimed at determining the phenolic content and antioxidant activities in four Australian-grown sweet cherry cultivars, including Bing, Ron’s, Merchant, and Lapins, as well as the identification of individual phenolic compounds with liquid chromatography–electrospray ionization–quantum time-of-flight–mass spectrometry (LC–ESI–QTOF–MS 2 ). Lapins exhibits the highest total phenolic content (TPC) value (1.73 ± 0.90 mg gallic acid equivalents (GAE)/g) while Ron’s exhibits the highest total flavonoid content (TFC) value (0.51 ± 0.02 mg QE/g). In 2,2′-azinobis-(3-ethylbenzo-thiazoline-6-sulfonic acid) (ABTS), reducing power assay (RPA), and total antioxidant content (TAC) assays, Merchant exhibited the highest values (0.51 ± 0.07, 1.74 ± 0.04, and 2.79 ± 0.09 mg AAE/g, respectively) and almost showed the highest antioxidant activity. Ron’s presented the highest value (1.21 ± 0.09 mg EDTA/g) in ferrous ion-chelating activity (FICA) assay and exhibits the strongest metal chelating ability. The correlation between phenolic contents and antioxidant assays was observed. In the LC–ESI–QTOF–MS 2 analysis, a total of 43 phenolic compounds has been detected in four sweet cherry cultivars, including 11 phenolic acids, 25 flavonoids, 5 other phenolic compounds, 1 lignan, and 1 stilbene. Venn graph showed that Lapins has the greatest number of unique compounds. Our study shows the presence of phenolic acids and provides information to be utilized as an ingredient in food, pharmaceutical, and nutraceutical industries.

“…Moreover, Hayward and SunGold samples had the most comparable phenolic profile, while Hayward and round organic Hayward shared the fewest phenolic compounds. In addition to fruit varieties, growing conditions also can affect phenolic content and composition [11,87]. However, Park, et al [12] stated that organically and conventionally grown kiwifruit exhibited similar bioactive compound content, but difference in polyphenol content was notable when comparing between cultivars.…”

Kiwifruit hold significant nutritional value and are a good source of antioxidants due to their diverse range of bioactive compounds. Kiwifruit waste is generated throughout the food supply chain, particularly during transportation and storage. Kiwifruit rejected from the retail market due to unfavorable appearance still possess potential economic value as kiwifruit are abundant in phenolic compounds. The present work studied the phenolic profile and antioxidant potential of rejected kiwifruit, including SunGold (Actinidia chinensis), Hayward (Actinidia deliciosa), and round organic Hayward (Actinidia deliciosa). Regarding phenolics estimation, SunGold possessed the highest TPC (0.72 ± 0.01 mg GAE/g), while Hayward exhibited the highest TFC (0.05 ± 0.09 mg QE/g). In antioxidant assays, SunGold showed the highest antioxidant activities in DPPH (0.31 ± 0.35 mg AAE/g), FRAP (0.48 ± 0.04 mg AAE/g), ABTS (0.69 ± 0.07 mg AAE/g), •OH-RSA (0.07 ± 0.03 mg AAE/g) assays, and FICA (0.19 ± 0.07 mg EDTA/g), whereas Hayward showed the highest RPA (0.09 ± 0.02 mg AAE/g) and TAC (0.57 ± 0.04 mg AAE/g). Separation and characterization of phenolics were conducted using LC-ESI-QTOF-MS/MS. A total of 97 phenolics were tentatively characterized from rejected SunGold (71 phenolics), Hayward (55 phenolics), and round organic Hayward (9 phenolics). Hydroxycinnamic acids and flavonols were the most common phenolics characterized in the three samples. The quantitative analysis was conducted by HPLC-PDA and found that chlorogenic acid (23.98 ± 0.95 mg/g), catechin (23.24 ± 1.16 mg/g), and quercetin (24.59 ± 1.23 mg/g) were the most abundant phenolics present in the rejected kiwifruit samples. The notable presence of phenolic compounds and their corresponding antioxidant capacities indicate the potential value of rescuing rejected kiwifruit for further utilization and commercial exploitation.

“…Phenolic compounds are a group of compounds with polyhydroxy groups on the aromatic ring, which exhibit strong antioxidant properties via different mechanisms, including reactive oxygen species scavenger by donating electrons or transferring hydrogen atoms, metal chelators, oxidase inhibitors, and antioxidant enzyme cofactors. , According to the number of phenol units within the molecular structure, substituent groups, and the linkage type between phenol units, phenolic compounds can be classified into monomeric polyphenols, including phenolic acids, flavonoids, stilbenes, and lignans, or polymeric polyphenols, such as tannins. , Modern research has demonstrated a significant positive correlation between phenolic compounds and antioxidant capacity, suggesting that the main contributor to antioxidant capacity might be the phenolic compounds in lotus . The phenolic content can be estimated by various spectrometric assays, including the total phenolic content (TPC), total flavonoid content (TFC), and total tannin content (TTC), while various spectrophotometric-based in vitro antioxidant methods are used to estimate the overall antioxidant potential of plant materials, including the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assay, ferric reducing antioxidant power (FRAP) assay, and total antioxidant capacity (TAC) assay. − However, TPC and other colorimetric methods neither separate nor quantify individual phenolic compounds.…”

Edible lotus ( Nelumbo nucifera G.) is widely consumed in Asian countries and treated as a functional food and traditional medicinal herb due to its abundant bioactive compounds. Lotus rhizome peels, rhizome knots, and seed embryos are important byproducts and processing waste of edible lotus ( Nelumbo nucifera G.) with commercial significance. Nevertheless, the comprehensive phenolic profiling of different parts of lotus is still scarce. Thus, this study aimed to review the phenolic contents and antioxidant potential in lotus seeds (embryo and cotyledon) and rhizomes (peel, knot, and pulp) grown in Australia. In the phenolic content and antioxidant potential estimation assays by comparing to the corresponding reference standards, the lotus seed embryo exhibited the highest total phenolic content (10.77 ± 0.66 mg GAE/g f.w. ), total flavonoid content (1.61 ± 0.03 mg QE/g f.w. ), 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity (9.66 ± 0.10 mg AAE/g f.w. ), 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) scavenging activity (14.35 ± 0.20 mg AAE/g f.w. ), and total antioxidant capacity (6.46 ± 0.30 mg AAE/g), while the highest value of ferric ion reducing antioxidant power (FRAP) activity and total tannin content was present in the lotus rhizome knot (2.30 ± 0.13 mg AAE/g f.w. ). A total of 86 phenolic compounds were identified in five parts of lotus by liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS/MS), including phenolic acids (20), flavonoids (51), lignans (3), stilbenes (2), and other polyphenols (10). The most phenolic compounds, reaching up to 68%, were present in the lotus seed embryo (59). Furthermore, the lotus rhizome peel and lotus seed embryo exhibit significantly higher contents of selected polyphenols than other lotus parts according to high-performance liquid chromatography (HPLC) quantification analysis. The results highlighted that byproducts and processing waste of edible lotus are rich sources of phenolic compounds, which may be good candidates for further exploitation and utilization in food, animal feeding, and pharmaceutical industries.
