“…However, for the DPPH scavenging activity, QS showed a similar trend with Q. serrata species. Another study also described that the extract from leaves of QS species showed higher DPPH scavenging activity than quercetin which was used as the control group (Kim et al, 2016 ). The particle sizes of QS leaf powder can also influence their antioxidant activities and bioactive compounds (Hong, 2019 ).…”

“…Studies have revealed that the extracts from the leaves and bark of QS contain a large concentration of phenolic compounds and were found to be significantly higher than two other Quercus species and Rhaphiolepis indica . In this regard, it has been suggested that QS is a promising natural ingredient that can be utilized in the pharmaceutical setting (Kim et al, 2016 ; Tuyen et al, 2016 ). Moreover, Lee and Park ( 2011 ) demonstrated the strong antioxidant activity and inhibitory effect of QS extract on tyrosinase and elastase, and they recommended the application of this extract in new functional cosmetics.…”

Quercus salicina Blume (QS) is an oak species that is indigenous to Japan and Korea. Historically, extracts of leaves, stems, barks and buds from the QS tree had been extensively utilized as herbal medicines. As rich sources of natural antioxidants, QS extracts could prevent oxidative stress and the occurrence of related neurodegenerative diseases. In pharmaceutical applications, decoction or infusion of comminuted QS powder is prepared as an herbal tea for oral use. Various extraction methods and extracting mediums showed the potential antioxidant activities of QS extracts, as well as the different types and levels of bioactive compounds found in them. Due to their functional properties and possibly low-level of cytotoxicity, the potential application of QS extracts as a novel food ingredient could be considered. In this review paper, a brief overview about QS extracts and their bioactive components, antioxidant activities, toxicity and technological applications is described based on previous works.

“…At the concentration of 5 mg/ mL, the DPPH radical scavenging activity was higher than that of quercetin (86.72 %) in the control group. [9] In the DPPH test, ABTS test, iron reduction antioxidant capacity (FRAP) test, and H 2 O 2 removal test of QS ultra-fine leaves powder, ball milling time was positively correlated with free phenol content and negatively correlated with phenols bound to the cell wall. [20] There is only one article about the antioxidant activity of QS stems, which is the study of its methanol extract.…”

“…The leaves are lanceolate, 5 -11 cm long and 1-2 cm wide, with hard teeth at the top, bright light green color on the front and dark green on the back, often gray-colored hair but yellow in autumn, and easy to transplant. [8][9][10] (Figures 1 and 2) QS is abundant in Tokushima Prefecture, Japan, and is recorded in the specification 2018 of Japanese pharmaceutical Bureau. Studies have shown that QS has multiple biological activities; in particular, tea drinks and drugs made from this herb are frequently used to treat urolithiasis.…”

The crude extracts of different parts (leaves and shoots) of Quercus salicina Blume (QS) have shown considerable effect in urolithiasis. QS has been widely used in clinical practice and has attracted great research interest The relevant published literature, however, reveals only partial education of its chemical components and bio-active mechanisms, and only two review articles have summarized the QS research progress. In this review, a comprehensive and systematic review of chemistry and pharmacodynamics of QS was carried out using the international authoritative databases (1959-2021), focusing on phenols and flavonoids, and their effect such as urinary stone dissolution, anti-inflammatory, anti-diabetes, anti-bacterial, antioxidant, and anti-allergy activities as well as toxic effects. The aim of review is to provide the most recent and effective literature support for further basic research and application development.

“…Ferulic acid, a phenolic acid, has vast conveyance plant kingdom and is more bioavailable than other dietary flavonoids and monophenolics studied in Table 1. It has been detailed to be a powerful antioxidant, antiinflammatory, and is accounted to terminate free radical chain reaction and decrease the chance for coronary heart diseases 3,[9][10][11][12][13][14] . Salicin is the metabolic antecedent of salicylic acid; a ponder compound.…”

Now a day's interest towards natural and has been growing due to the unhealthy consequences of chemicals in the health industry; though, herbal substances possess several quality control and confirm pharmacological action issues. This present study was designed to determine the effects of Salix alba L. methanolic extract (MESAL) for its antioxidant and anti-inflammatory activity in rat models. Further to establish and validate a sensitive, fast and reproducible high performance thin layer chromatographic (HPTLC) method of two biomarker compounds Salicin and Ferulic acid from MESAL. The antiinflammatory activity was studied by the carrageenan-induced rat paw oedema method while DPPH free radical scavenging ability was utilized to determine the antioxidant activity. Additionally, the separation was performed by HPTLC with quantification of markers (Salicin and Ferulic acid). Among the different combinations of mobile phases used, the best separation was achieved in Toluene: Ethyl acetate: Methanol: Formic Acid (5:3:1:1v/v/v/v). The MESAL exhibited antioxidant activity with a maximal inhibitory concentration (IC 50 ) value of 400 µg/ml, and exerted anti-inflammatory activity, wherein 70 % protection was shown at 400 mg/ml. In contrast, HPTLC method gave compact spots of Salicin and Ferulic acid at R f 0.22 ± 0.02 and 0.68 ± 0.02, respectively. The MESAL displayed potent antioxidant and anti-inflammatory properties. Statistical analysis proves that the HPTLC method is repeatable and selective for the estimation of the said drugs, thus can be used for routine analysis and quality control of raw material of Salix alba L.
