“…The results of DPPH study in this study showed that the leaf and seed tea of persimmon are good free radical scavengers. Results of Jang et al (2010) and Akter et al (2010) also showed that Values are the mean±SD of triplicate experiments. Different superscripts in the same column followed by the values are significantly different at p<0.05.…”

“…Not only the fruits but also other parts of persimmon like leaves and seeds are found to contain different phytochemicals having nutritive and medicinal values. Persimmon seeds possess high antioxidant potential and also contain high level of unsaturated fatty acids (Jang et al, 2010). Persimmon leaf extract showed therapeutic potential to alleviate the severity of radiation-induced liver injury, hyperglycemia, hypoinsulinemia, and dyslipidemia in rats (Ashry et Huang et al (2016) indicated that persimmon leaves contained a potent protective effect on cognitive deficits induced by amyloid beta in rats.…”

Acceptance of green tea, a health promoting functional food material, could be increased if its flavor is improved. Persimmon seeds and leaves are likely potential options for green tea improvement since they contain a large number of volatile flavor compounds. In the present study, amino acids, volatile flavor compounds, and antioxidant potentials of persimmon tea (PT) prepared with green tea were investigated. PT contained 8 essential amino acids, most of which are associated with learning ability and memory as well as stroke and neurodegenerative diseases prevention. Total free amino acid was high in persimmon seed tea (273.37-300.61 µg/mL) as compared to persimmon leaf tea (179.75-198.44 µg/mL). Total phenol content of persimmon leaf tea ranged from 333.07 to 348.87 GAE µg/g and that of seed tea from 324.63 to 356.73 GAE µg/g. Some of the volatile flavor compounds such as 2-undecanone; furfural; 5-methyl furfural; benzoic acid, methyl ester; benzaldehyde, 4-methyl; and phenol, 2,4-bis (1,1-dimethylethyl) were found in persimmon leaf and seed tea. The results of the present study suggest that persimmon leaf and seed could offer good options to enhance the preference of green tea along with its nutritional value.

“…In this method, O2 •-derived from dissolved oxygen by PMS-NADH coupling reaction reduces the yellow dye (NBT 2+ ) to produce the blue formazan, which was measured spectrophotometrically at 560 nm. It was found that plant samples containing antioxidant molecules are able to inhibit the formation of blue formazan complex [30,31]. The decrease in absorbance at 560 nm with plant extract indicates the consumption of O2 •-in the reaction mixture.…”

Objective: To investigate the antioxidant activity of ethanolic extract of Terminalia bellerica fruit pulp (TBFP), seed (TBS) and bark (TBB), and identification of phytochemical constituents of said extracts. Methods:The antioxidant potential of T. bellerica (TB) parts was evaluated by free radical scavenging activity (FRSA), superoxide anion radical scavenging activity (SARSA), hydroxyl radical scavenging activity (HRSA) and compared with reference standard quercetin. Lipid peroxidation (LPO), ferric thiocyanate activity (FTC) and reducing power (RP) of the plant extracts were also examined. The phytochemical constituents of said extracts have been quantified by gas chromatography-mass spectrometer (GC-MS) method.Results: Ethanolic extract of TBFP exhibited high phenolic content (254.33) followed by TBS (227.33) and TBB (185) mg/g of GAE. TBFP showed lowest IC 50 for FRSA (62 µg/ml), SARSA (39 µg/ml) and HRSA (27 µg/ml) and highest RP (3.39 ascorbic acid equivalents/ml). TBB showed lowest IC 50 for LPO (48 µg/ml) whereas TBS showed lowest IC50 Conclusion: On the basis of correlation of antioxidant studies with total phenolic content (TPC) and GC-MS analysis of different part of TB, it may be concluded that high concentration of total phenolics and other bioactive phytochemicals of TB extracts make it a potential source of nutraceutical antioxidants.for FTC (109 µg/ml). Predominant phyto-compounds present in TB extracts were quinic acid, gallic acid, ethyl galate, 9, 12 octadecadienoic acid and glucopyranose in varying concentrations as analyzed by GC-MS.

“…The antioxidant properties of phenolic compounds originate from their properties of donating eto free radicals to stabilize them. Therefore, the quantity of TPC in methanolic and aqueous extracts of T. bellerica was determined ( Figure 1) in order to determine the antioxidant capacity of plant extracts (Jang et al, 2010;Sampath Kumara et al, 2012). According to Shahriar et al (2012) and Venkatesan et al (2017) hexane and chloroform extracts of Terminalia arjuna fruit (73.00 and 61.72 mg/g of GAE) and Terminalia chebula bark (28.68 and 62.68 mg/g of GAE) exhibited lower TPC in comparison to the reported values of methanolic extracts in this study.…”

Terminalia bellerica Roxb., commonly known as Beleric myrobalan, is a well-known large deciduous tree with various pharmaceutical properties. However, scientific information on T. bellerica, growing in India, as regards to its phytochemical constituents and pharmacological properties is very limited. With this in view, this study investigated the antioxidant, DNA protective and antibacterial activities of different parts (fruit pulp, seed and bark) of T. bellerica. Methanol (70%) and water (100% distilled water) were used for the extraction and analysis of total phenolic contents (TPC). Plant extracts were further screened for antibacterial activity against both gram (+) and gram (-) bacteria and minimum inhibitory concentration (MIC) values were calculated. Amongst the tested extracts, methanolic extract contained more TPC than aqueous extract. Methanolic fruit pulp (MEFP) showed lower IC 50 (118.7 µg/ml) for free radical, (77.65 µg/ml) superoxide anion radical, (73.76 µg/ml) hydroxyl radical scavenging activity, (115.6 µg/ml) lipid peroxidation and (184.98 µg/ml) ferric thiocyanate assay. Methanolic extract also exhibited more potential DNA protective and antibacterial activity than aqueous extract. Furthermore, the correlation between TPC and antioxidant studies revealed that phenolics are mainly responsible for antioxidant, DNA protective and antibacterial activities of T. bellerica. This study suggests that the methanolic extract of T. bellerica could be a potential source of natural antioxidants.
