“…However, other antioxidant methods are needed to make a full assessment upon the low antioxidant activity of these samples At the same time, the secondary metabolite group, tannins, saponins and flavonoids, were found to be present in the plant in preliminary qualitative phytochemical analysis. In other studies on Acer species, the fact that different tannin compounds are responsible for many different activities [35,39,40]. The presence of such tannin compounds in this species suggested that the tannins content of ACC extracts should be examined in future studies.…”

“…A. ginnala Maxim. ), while the water and hexane subextracts (50.0 μg/mL and 46.3 μg/mL, respectively) were less active than the standards [35]. Also, the alcohol extract of A. rubrum (antioxidant capacity = 3325 ± 129) showed higher activity and the alcohol extract of A. saccharum (antioxidant capacity = 968 ± 155) exhibited less activity than the commercial standardized French maritime pine bark extract Oligopin ® (antioxidant capacity = 1930 ± 101) [36].…”

This study on Acer campestre L. subsp. campestre, used traditionally in treatments of various inflammation disorders, especially hemorrhoids and rheumatism, aimed to determine the total phenolic contents, the antioxidant and antimicrobial potentials, and the chemical composition profile of the extracts and subextracts from maple syrup and Acer campestre L. subsp. campestre leaves and twigs. The antioxidant activities of maple syrup extracts and subextracts were examined by 2,2-diphenyl-1-picryl-hydrazyl (DPPH), and the total phenolic contents of all samples were determined using the Folin-Ciocalteu reagent (FCR) method. Also, they were tested for their antimicrobial activities by microbroth dilution technique. Catechic tannin, saponins and flavonoids are determined in its leaves and twigs by preliminary qualitative phytochemical analysis. The alcoholic extracts obtained by 48-hour maceration (91.2%), ethyl acetate subextract of alcohol extracts obtained by 24-hour maceration (91.1%) and alcohol extracts obtained by 24-hour maceration (88.8%) exhibited higher radical scavenging activity than other samples, while the decoction and infusion had moderate activities. Beside of this, it was found that the syrup and its subextracts have more total phenolic contents than other extracts. The alcohol extracts obtained by 24-hour maceration and by 48-hour maceration exhibited higher activity against Candida albicans (78 μg/mL and 156 μg/mL, respectively). Only the alcohol extract obtained by 48-hour maceration and ethyl acetate subextract of syrup showed an activity against Escherichia coli, while all samples except butanol subextract of syrup have an antibacterial activity against Pseudomonas aeruginosa.

Chromatographic isolation of the 80% MeOH extract of Acer ginnala (AG) yielded seven galloyl derivatives: gallic acid (1), ginnalin B (2), acertannin (3), maplexin D (4), maplexin E (5), quercetin-3-O-(2′′-galloyl)-α-L-rhamnopyranoside (6), and kaempferol-3-O-(2′′-galloyl)-α-L-rhamnopyranoside (7). This is the first study to report the isolation of compounds 4 and 5 from AG. Galloyl derivatives 3–7 exhibited potent radical scavenging activities, with 5 and 7 showing particularly strong inhibitory activities against nitric oxide production in lipopolysaccharides- (LPS-) stimulated RAW264.7 cells. In addition, oral administration of AG extract (500 mg/kg b.w.) improved symptoms of hyperglycemia and blunted the increases in serum GOT/GPT levels in a rat model of streptozotocin-induced diabetes. These results suggest that galloyl derivatives (1–7) are antioxidant and anti-inflammatory agents and that AG extract has potential as a functional material or novel herbal medicine for treating diabetes mellitus.
