Oral Squamous Cell Carcinoma (OSCC) is one of the most prevailing malignancies of the head and neck area. So far, treatment methods are associated with harmful effects which drive attention towards natural compounds such as coffee. The current study attempted to test the anti-cancerous effect of green coffee, medium roasted coffee and decaffeinated coffee in OSCC cell lines and correlate the obtained results with their total phenolic content. We prepared coffee extracts using soxhlet apparatus. Then, we purchased and sub-cultured OSCC-25 cell into four study groups. We subjected three of those groups to coffee extracts separately. We left the remaining group without any treatment as a control group. We assessed cell cytotoxic effect of each extract by MTT viability assay. Additionally, we evaluated the apoptotic effect of each extract on OSCC-25 cell lines using flowcytometric analysis. Finally, we measured the total phenolic content in each coffee extract. The results revealed that coffee extracts induced varying degrees of cell cytotoxicity and apoptosis. Green coffee showed the highest cytotoxic and apoptotic effect followed by medium roasted coffee, then decaffeinated coffee. The total percentage of necrotic cells were higher in the coffee extracts groups, compared to the control group with a higher value in favor of green coffee followed by medium roasted coffee. Upon chemical analysis, the results showed that green coffee extract contained the highest concentration of phenolic compounds followed by medium roasted coffee then decaffeinated coffee extracts. We concluded that green coffee was the most potent anti-cancer extract. It seems plausible that coffee, and particularly green coffee could be for treating of OSCC.

Diplotaenia turcica is widely utilized in conventional treatment in the east of Turkey. Due to the insufficient data on the safety profile, the acute and sub acute toxicity of Diplotaenia turcica was determined. Furthermore, total phenolic content, flavonoid content and antioxidant activity of the extract were determined. The acute toxicity of hydroalcoholic root extract of Diplotaenia turcica (HREDT) was evaluated in mice after administration of single oral dose at the 5000 mg/kg (acute model) and rat after 28 days orally administration at the dose range of 250, 500 and 1000 mg/kg (subacute model). According to result, the LD50 value of HREDT was found to be greater than 5000 mg/kg. In sub acute toxicity study, no statistically significant differences were observed in the values of hematological and pathological parameters in comparison with control group. It was determined that the glucose, triglyceride, cholesterol and LDL levels exerted a significant effect depending on the HREDT doses. The results from the present study found out that HREDT did not produce any toxic effects or deaths in animals for both single and chronic administration. Additionally, HREDT showed moderate antioxidant activities and exhibited relatively notable total phenolic content.

Background: Curcuma heyneana (Valeton & Zijp.) or temu giring has various pharmacological activities. However, its hepatoprotective activity toward ethanol induction has never been carried out. Objectives: The objective of this research was to evaluate the hepatoprotective activity of the C. heyneana rhizome extract toward Wistar rats induced by ethanol. Methods: The research was initiated with the determination of curcuminoid content, total phenolic content, total flavonoid content, and characterization of extract using gas chromatography-mass spectrometry (GC-MS). Hepatoprotective activity was tested using the C. heyneana extract at doses of 50, 100, and 150 mg/kg with 5 g/kg ethanol as an inducer. Aspartate transaminase (AST), alanine transaminase (ALT), liver weight, and macroscopic and microscopic liver were used as parameters. Data were analyzed using analysis of variance (ANOVA). Results: The curcuminoid content of the extract was 1.18% (w/w). Total phenolic content of the C. heyneana extract was 400.37 mg gallic acid equivalent (GAE)/g sample, while total flavonoid content was 27.25 mg quercetin equivalent (QE)/g sample. Nine compounds were identified in the extract. Administration of the extract at doses of 50, 100, and 150 mg/kg kept the liver normal. It was identified macroscopically from the dark red color without any white spot and normal liver weight. Furthermore, at doses of 50, 100, and 150 mg/kg, the extract inhibited AST and ALT elevation, which was significantly different from the negative control group (P < 0.05). The extract also prevented hepatocyte injury that was seen microscopically. Conclusions: It can be concluded that the C. heyneana extract at doses of 50, 100, and 150 mg/kg is effective as hepatoprotective in the liver injury induced by ethanol.

Dpph Method

A free radical is one of the triggers of degenerative diseases that become the biggest cause of death. Excessive production of free radicals can be neutralized by antioxidant. Antioxidants can be generated from within the body (intracellular). One of them by the enzyme SOD (superoxide dismutase). However, when the production of free radicals exceeds the ability of intracellular antioxidants to neutralize it, antioxidants from outside (extracellular) is necessary. The ethanol extract of Artocarpus camansi leaves (EEACL) contains phenolic compounds which has very strong antioxidant activity based on in vitro study using the DPPH method, but the in vivo study about the total phenolic content effect of its leaves toward antioxidant activity has not been done. 25 mice were divided into 5 groups consisting of control group, a group was induced by stress and three groups were induced by stress, but given EEACL with each dose of 50 mg/kg bw, 100 mg/kg bw and 150 mg/kg bw. Inducing stress in the form of psychological stress was carried out for 7 days and continued with the EEACL administration for 7 days. The mice were dissected and the livers were isolated, then the liver morphological was examined using Hematoxyllin Eosin (HE) staining method and SOD level was examined with immunohistochemical staining method. The data were analyzed with One Way ANOVA and Duncan test using SPSS program version 19.0. Total phenolic content of EEACL is 235.03 ± 4.306 mg GAE/ g of sample. The average SOD levels in the control group is 94.05 %, stressed group is 55.94 %, stress with EEACL dose 50 mg/kg bw group is 58.40 %, stress with EEACL dose 100 mg/kg bw group is 79.68 %, stress with EEACL dose 150 mg/kg bw group is 80.90 %. Based on statistical result, SOD level increased along with the increase of EEACL dose, but not significantly (p < 0,05). Total phenolic content of EEACL has an influence to SOD levels. SOD level increased along with the increase of EEACL administration dose. The higher dose of EEACL leading to higher levels of SOD in the mouse liver.Keywords : total phenolic content, superoxide dismutase, antioxidant, Artocarpus camansi

Functional Product

In this study, it is aimed to obtain a new and functional product as a result of adding the remaining black carrot into powder form in different proportions (10, 20 and 30%). Biscuits without waste fermented carrot powder (WFCP) were taken as control group. When ascorbic acid, total phenolic content and antioxidant activity values of WFCP were examined, it was found 1032.75 mgAA / 1000g, 4254.92 mg GAE / kg dry weight and % inhibition 43.30, respectively. The textural properties of the biscuit dough with the addition of AFHT were investigated. Moreover, the effect of adding WFCP on colour values, water activity, moisture, ash, ascorbic acid, total phenolic content, antioxidant activity and textural properties of biscuits were determined. With the addition of WFCP, L* and b* values were decreased and a* values were increased in biscuits compared to control sample. Water activity and ash values increased as WFCP rate increased in biscuits. Ascorbic acid, total phenolic and antioxidant activity (DPPH) values of biscuits added with WFCP (30%) increased by 4.89, 7.22 and 4.04 times, respectively, compared to the control group. The addition of WFCP also improved the textural properties of the biscuits, while the hardness value of control group was found to be 4175.87 g force, the highest hardness value was obtained as 6494.09 g force for 20% WFCP added biscuits. In sensory evaluation, the biscuits with the addition of 10% WFCP gained the highest likelihood with 5.6 in terms of general acceptability.

Flavonoid Content

The current investigation is intended to evaluate the content of phytochemical constituents and antioxidant potential of hydroalcoholic extracts of stem and root of Grewia serrulata DC (HAESGS & HAERGS) and leaf and bark of Grewia Nervosa (Lour.) panigrahi (HAELGN & HAEBGN). Initially, all the extracts at different concentrations were estimated for their total phenolic content and total flavonoid content. The study was further extended for their antioxidant potential evaluation using various in vitro methods such as 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical, hydroxyl radical and superoxide radical scavenging assays. The total phenolic content (mg gallic acid equivalent per gram of extract) was high in HAELGN (170.82±0.19) and HAERGS (123.00±0.48) than HAESGS (111.2±0.26) and HAEBGN (119.60±0.23). The total flavonoid content (mg quercetin equivalent per gram) is greater in HAERGS (71.24±0.50) and HAESGS (65.68±0.27) than HAELGN (55.82±0.35) and HAEBGN (62.38±0.45). The IC50 values (µg/ml) of different plant extracts inferred that DPPH radical scavenging activity is greater in HAELGN (42.91±0.88) and HAEBGN (53.87±0.35) than HAESGS (126.73±1.20) and HAERGS (88.87±1.25). However, hydroxyl and superoxide radical scavenging activity is more in HAERGS (135.41±1.19 & 88.00±1.42) and HAELGN (172.28±1.91 & 108.163±1.09) than HAESGS (237.3±1.65 & 110.074±0.87) and HAEBGN (204.7±1.04 & 125.54±1.07). The results of present comprehensive analysis demonstrated that both the plants Grewia serrulata DC and Grewia Nervosa (Lour.) panigrahi possess high phenolic, flavonoid contents and potential antioxidant activity, and could be used as a valid source of natural antioxidants and might be utilized for pharmacological screening of various therapeutic activities.
