“…Prior to this study, polyphenolic characterization of species in Betulaceae was performed, and isorhamnetin, quercetin, kaempferol, and their glycosides were identified as major flavonoids, which contribute to the anti-melano effect and antioxidant activity [40]. Furthermore, gallic acid and flavonoids were major polyphenols in plants in the Fagaceae family, which contribute to antioxidant activity [41,42]. Similar to the Betulaceae and Fagaceae, Aceraceae species were reported to exhibit antioxidant activity due to various phenolic compounds, such as quercetin, kaempferol, and flavonoid derivatives [43].…”

Chemotaxonomic metabolite profiling of 62 indigenous Korean plant species was performed by ultrahigh performance liquid chromatography (UHPLC)-linear trap quadrupole-ion trap (LTQ-IT) mass spectrometry/mass spectrometry (MS/MS) combined with multivariate statistical analysis. In partial least squares discriminant analysis (PLS-DA), the 62 species clustered depending on their phylogenetic family, in particular, Aceraceae, Betulaceae, and Fagaceae were distinguished from Rosaceae, Fabaceae, and Asteraceae. Quinic acid, gallic acid, quercetin, quercetin derivatives, kaempferol, and kaempferol derivatives were identified as family-specific metabolites, and were found in relatively high concentrations in Aceraceae, Betulaceae, and Fagaceae. Fagaceae and Asteraceae were selected based on results of PLS-DA and bioactivities to determine the correlation between metabolic differences among plant families and bioactivities. Quinic acid, quercetin, kaempferol, quercetin derivatives, and kaempferol derivatives were found in higher concentrations in Fagaceae than in Asteraceae, and were positively correlated with antioxidant and tyrosinase inhibition activities. These results suggest that metabolite profiling was a useful tool for finding the different metabolic states of each plant family and understanding the correlation between metabolites and bioactivities in accordance with plant family.

“…The QI galls possessed potent free radical quenching and potent antioxidant activity when tested both in chemical as well as biological models [40]. The main constituents found in the QI galls are tannins (gallotannic acid) (50% -70%), gallic acid (2% -4%), ellagic acid, sugar and essential oils [41].…”

The galls of the Quercus infectoria (QI) tree are traditionally believed to have great medicinal value. Pharmacologically the galls are claimed to have various biological activities such as astringent effect, antidiabetic, antitremorine, local anaesthetic, antipyretic, anti-inflammatory, antibacterial, antiviral and many more. These pharmacological activities of gall extracts were reported to be due to its excellent antioxidant activity with phytochemicals constituents of phenolic and flavanoid compounds. The phenolic compounds or polyphenols can act on bone metabolism by modulating osteoblast proliferation, differentiation and mineralization, as well as osteoclastogenesis. In addition, elemental and physico-chemical analysis indicated the presence of important minerals in QI, such as calcium, magnesium, phosphorus, oxygen, potassium, aluminium, carbon, zinc, iron, manganese, nickel and silica. The current review will be focusing on the potential bone health benefits of the well-known traditional herbal medicine, QI or locally known as the "manjakani".

“…Polyphenols are known to possess varied roles; they are potent free radical scavenger protecting the constituents of the cells from damage due to oxidative stress -thereby preventing various chronic diseases associated with it. The antioxidant activity of the polyphenols is due to their structure and to their redox property to either accept or donate the electrons which causes the delocalisation of unpaired electrons in their aromatic structure 19 , the antioxidant activity of the Quercus infectoria has been studied for their antioxidants 20 and is shown to contain efficient free radical scavenging activity. Due to geographical difference and the weather conditions there may be difference in the content and the biological activity.…”

Quercus infectoria seeds were used in the present study, and fatty acid content in fixed oil was determined using GC-FID. The total amount of the oil present in the seed was 7.2%. The major fatty acid identified were oleic acid (58.13%), linoleic acid (19.84%), palmitic acid (15.99%), stearic acid (2.27%), α-linolenic acid (1.31%) and other constituents like heptadecanoic acid, cis-11-eicosenoic acid, cis-10-heptadecenoic acid, behenic, lignoceric and myristic acid with less the 1%. Due to its phenolic compounds and α-tocopherol, the oil exhibits its antioxidant activity. Antioxidant properties of the oil were determined via DPPH radical scavenging and β-carotene bleaching assay. The physical properties and UV and FT-IR spectra were also determined.
