“…In accordance, antioxidant compounds other than phenolic substances may play a major role in determining antioxidant activity in the various tissues of the sea cucumbers, though phenolic substances may be strong contributors to the antioxidant activity in holothurian muscle tissues. It is also possible that specific phenolic compounds play major roles, and that higher antioxidant activities are thus determined by particular phenolic profiles [ 30 , 35 , 36 ] and not by a high overall total of phenolic substances. For instance, antioxidant activity, such as that measured using FRAP, was related to the total flavonoid (a specific class of phenolic compounds) content in H. scabra [ 37 ].…”

Biological activity and bioactive compound content in sea cucumbers was assessed, considering Parastichopus regalis, Holothuria mammata, Holothuria forskali, and Holothuria arguinensis as species and intestine, muscle band, respiratory tree, body wall, and gonads as tissues. P. regalis had the lowest content in phenolic compounds and antioxidant activity in contrast to Holothuria species. In the respiratory tree, the highest phenolic concentration was recorded in H. arguinensis, 76.4 ± 1.2 mg GAE/100 g dw vs. 21.0–49.0 mg GAE/100 g dw in the other species. H. arguinensis had the highest DPPH and FRAP results in the gonads, 13.6 ± 0.7 mg AAE/100 g dw vs. 2.6–3.5 mg AAE/100 g dw and 27.1 ± 0.3 μmol Fe2+/g dw vs. 8.0–15.9 μmol Fe2+/g dw, respectively. Overall, P. regalis biomass presented the highest anti-inflammatory activity levels and H. arguinensis the lowest anti-inflammatory levels. The respiratory tree was the most anti-inflammatory (measured by the inhibition of cyclooxygenase-2, COX-2) tissue in H. mammata and H. forskali (also the muscle band in this case), 76.3 ± 6.3% and 59.5 ± 3.6% COX-2 inhibition in 1 mg/mL aqueous extracts, respectively. The results demonstrated a variable bioactive potential and advantage in targeting antioxidant properties in the muscle band and anti-inflammatory activity in the respiratory tree, which may constitute a starting point for a biorefinery approach envisaging multiple applications.

“…27 They found that the TPC and TFC values of these fruits ranged from 360.81 to 398.48 mg GAE/g and 13.69 to 23.87 mg QE/g, respectively. Other recent studies have reported TPC and TFC values for a variety of plant extracts, including Salvia aytachii ethyl acetate extract (TFC 22.33 ± 0.17 μg QE/mg), 46 seeds of seven sunflower methanol extracts (TPC 22.29-33.09 mg GAE/g), 47 sea cucumber tentacles (TPC 2.4138 mg GAE/g), 48 Ficus sycomorus L. hexane extract (TPC 1980.4 mg GAE/g; TFC 109.9 mg QE/g), 1 Aerva javanica methanol extract (TPC 44.79 mg GAE/g; TFC 28.86 mg QE/g), 49 and Australian native fruits (TPC 23.04 to 74.84 mg GAE/g and TFC 8.31 to 20.63 mg QE/g). 50 These findings demonstrate the wide range of TPC and TFC values that can be obtained from different plant extracts and highlight the importance of carefully selecting the extraction method and solvent to obtain accurate and reliable results.…”

BACKGROUNDCrataegus orientalis Pall. ex M. Bieb fruit (COPMB) is extensively used as a source of various products in the medicinal‐aromatic field and holds the potential for erosion control, ornamental purposes, food source, and economic benefits for forest villagers from its fruits. This study aims to determine the chemical components and biological activities of extracts prepared from COPMB using different solvents.RESULTSThe present work was designed to define the antioxidant activity [phosphomolybdenum (total antioxidant capacity), 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) (ABTS), ferric reducing antioxidant power (FRAP), cupric ion‐reducing antioxidant capacity (CUPRAC) and metal chelating activity (MCA)], phytochemical screening analysis, enzyme inhibitor (α‐amylase, α‐glucosidase and tyrosinase) potential, and liquid chromatography‐high resolution mass spectrometry (LC‐HRMS) secondary metabolite profiling in different extracts of COPMB. The results of LC‐HRMS revealed that fumaric acid was the main phenolic compound in all extracts. Among the extracts, ethyl acetate extract has the highest phytochemical and antioxidant properties [total phenolic content (TPC): 32.5 mg GAE/g, total flavonoid content (TFC): 12.2 mg QE/g, ABTS: 213.0 mg TE/g; CUPRAC: 126.0 mg TE/g, MCA: 145.0 mg EDTA/g; FRAP: 122.8 mg TE/g; TAC: 2.8 mmol TE/g]. Ethyl acetate and methanol extracts are more effective in α‐amylase (0.27 ± 0.01 mg/mL; 0.12 ± 0.00 mg/mL), α‐glucosidase (0.63 ± 0.02 mg/mL; 0.77 ± 0.02 mg/mL) and tyrosinase (0.03 ± 0.00 mg/mL; 0.03 ± 0.00 mg/mL) enzyme inhibition potentials compared to standard acarbose (0.75 ± 0.02 mg/mL for α‐amylase; 1.11 ± 0.03 mg/mL for α‐glucosidase) and kojic acid (0.04 ± 0.00 mg/mL).CONCLUSIONThe findings from this study suggest that COPMB could serve as a valuable source of natural agents for the food and pharmaceutical industry. © 2024 Society of Chemical Industry.

“…The major phenolics present in plants are flavonoids, phenolic acids, tannins, stilbenes, lignans, and coumarin [ 26 , 27 , 28 ]. Phenolic compounds are well known as antioxidants, which demonstrate inhibitory activities against α-glucosidase and tyrosinase activities as well as LDL-cholesterol, DNA, and lipid oxidation [ 29 ].…”

“…In addition, Cho et al [ 39 ] reported the potential of PL as a cosmetical ingredient with a potent whitening effect due to the ability of phenolic compounds (e.g., (+)-gallocatechin and prodelphinidin B-3) obtained from PL to show inhibition against melanin biosynthesis in melanoma cells and tyrosine enzymes. Tyrosinase is involved in the biosynthesis of melanin pigments and excessive melanin is linked to skin darkening and neurodegenerative disorders [ 29 ]. In another study, Xue et al [ 34 ] identified different phenolic compounds from PL and found that only chrysontemin showed tyrosinase inhibitory activity, and also suggested that the most prominent moiety in inhibiting tyrosinase enzyme was the 3′,4′-dihydroxy groups of the catechol.…”

Persimmon is a delicious fruit, and its leaves are considered a valuable ingredient in food, beverage, pharmaceutical, and cosmetic sectors. Traditionally, persimmon leaves (PL) are used as a functional tea in Asian culture to cure different ailments, and are also incorporated into various food and cosmeceutical products as a functional ingredient. PL mainly contain flavonoids, terpenoids, and polysaccharides, along with other constituents such as carotenoids, organic acids, chlorophylls, vitamin C, and minerals. The major phenolic compounds in PL are proanthocyanidins, quercetin, isoquercetin, catechin, flavonol glucosides, and kaempferol. Meanwhile, ursolic acid, rotungenic acid, barbinervic acid, and uvaol are the principal terpenoids. These compounds demonstrate a wide range of pharmacological activities, including antioxidant, anticancer, antihypertensive, antidiabetic, anti-obesity, anti-tyrosinase, antiallergic, and antiglaucoma properties. This review summarizes the latest information on PL, mainly distribution, traditional uses, industrial potential, and bioactive compounds, as well as their potential action mechanisms in exhibiting biological activities. In addition, the effect of seasonality and geographical locations on the content and function of these biomolecules are discussed.
