The aim of this study was to investigate the anticancer activities of five chloroform extracts prepared from the aerial parts of Centeura kilaea Boiss. (CKC), C. cuneifolia Sm. (CCC), C. salicifolia M.Bieb. ex Willd. (CSAC), C. stenolepis Kerner (CSC1 and CSC2) against hepatocellular cancer HepG2 cell line. At the same time, antioxidant and anti-inflammatory activities of the extracts were examined. Anticancer, anti-inflammatory, antioxidant activities of extracts were carried out by MTT, lipoxygenase, DPPH-ABTS methods, respectively. CCC, CSAC and CKC have the highest anticancer activity when compared to other extracts. Similarly, CSAC and CCC had the best antioxidant capacity, while CSAC and CKC showed strong anti-lipoxygenase activity. Among all the tested extracts, the highest amounts of total phenolic were found in the CSAC. The study revealed that CSAC and CCC displays remarkable antioxidant, anticancer and anti-inflammatory activity.

Context: Linum usitatissimum (Linn); known as Flaxseed, is one of the most important medicinal plants traditionally used for health benefits and also as nutritional purposes. Objective: Estimation of total phenolic and flavonoid contents, and evaluation of the antioxidant, antiinflammatory and anticancer activities have been performed on hexane, ethyl acetate, n-butanol, and methanol extracts and also on fractions of methanol extract (hexane, ethyl acetate, and n-butanol). Materials and Methods: Phenolic and flavonoid contents were detected using spectrophotometric and colorimetric assays. Antioxidant and anti-inflammatory activities were estimated in-vitro. Anticancer activity of extracts was tested on Hepatocellular carcinoma cell line (HepG2) and breast cancer cell line (MCF7). Results: The methanolic extract and its ethyl acetate fraction showed higher contents of total phenols and flavonoids. Also, the methanolic extract showed a higher antioxidant activity. The butanolic and ethyl acetate fractions at concentration 500μg/ml yielded a higher percent of inhibition of protein denaturation; 87.9% and 90%, respectively. The ethyl acetate fraction and the methanolic extract showed an obvious anticancer activity against HepG2 and MCF7 (IC50=60±0.24 and 29.4±0.12μg. ml-1) and (IC50=94.7±0.21 and 227±0.48μg. ml-1), respectively. The GC-MS analysis showed that the methanolic extract had 32 compounds whereas the ethyl acetate and butanol fractions contained 40 and 36 compounds, respectively. Conclusion: Flaxseed contains different biologically active compounds that have been found to possess various activities, which can protect the human body against several diseases.

Scrophularia tenuipes is an Algerian-Tunisian endemic species, which has not been studied yet. Ethyl acetate (EA) and n-butanol (Bu) fractions obtained from Scrophularia tenuipes were investigated for their health benefit properties, in particular with respect to in vivo/in vitro anti-inflammatory and antioxidant activities, as well as their potential to inhibit key enzymes with impact in diabetes (α-glucosidase and α-amylase). The fractions had a distinct phytochemical composition, of which EA was richer in total phenolic compounds (225 mg GAE/g) and mostly composed of the phenylethanoid acetyl martynoside. Compared to EA, Bu had higher amounts of total flavonoids, and according to the result obtained from UHPLC-DAD-ESI-MSn analysis, harpagoside (iridoid) was its major phytochemical. EA fraction was quite promising with regard to the in vivo (at 200 mg/kg, po) anti-inflammatory effect (62% and 52% for carrageenan-induced rat paw edema and xylene-induced ear edema tests, respectively), while Bu fraction exhibited a stronger antioxidant capacity in all tests (IC50 = 68 µg/mL, IC50 = 18 µg/mL, IC50 = 18 µg/mL and A0.50 = 43 µg/mL for DPPH●, ABTS•+, O2•− scavenging assays and cupric-reducing antioxidant capacity method, respectively). Both fractions also showed a strong effect against α-amylase enzyme (IC50 = 8 µg/mL and 10 µg/mL for EA and Bu fraction, respectively).

Objectives.Salvia fruticosaMill. (S. fruticosa) is widely used in folk medicine. Accordingly, the present study was designed to evaluate the antioxidant and anti-inflammatory activities ofS. fruticosa, and to determine the phenolic constituents of its extracts.Methods. The antioxidant activity was determined using 2,2-diphenylpicrylhydrazyl assay. Total phenolic contents were estimated using Folin-Ciocalteu reagent, and high-performance liquid chromatography was performed to identify phenolic constituents. To evaluate the anti-inflammatory activity, carrageenan-induced mouse paw edema was determined plethysmographically.Key Findings. Different plant extracts demonstrated strong radical scavenging activity, where the ethyl acetate extract had the highest value in the roots and the lowest in the aerial parts. This antioxidant activity was correlated to the total phenolic content of different extracts, where rutin and luteolin were the most abundant constituents. Interestingly, both the roots and aerial parts revealed a significant anti-inflammatory activity comparable to diclofenac.Conclusions. This study is the first to demonstrate pharmacologic evidence of the potential anti-inflammatory activity ofS. fruticosa. This activity may partly be due to the radical scavenging effects of its polyphenolic contents. These findings warrant the popular use of the East Mediterranean sage and highlight the potential of its active constituents in the development of new anti-inflammatory drugs.

This study was carried out to evaluate the anti-inflammatory and antioxidant activities of Cucumis sativus Linn. (Family: Cucurbitaceae) leaves. The methanolic extract of C. sativus leaves (MCS) was investigated for antiinflammatory activities in Long Evans rat model at two different doses of 150 and 250 mg/kg body weight and the effects were compared with the standard, indomethacin (10 mg/kg body weight). It exhibited highest antiinflammatory activity at the dose 250 mg/kg. In the formalin test, the extract at both doses (150 and 250 mg/kg body weight) significantly prevented the increase in volume of paw edema (P<0.05 and P<0.001). In carrageenan-induced paw edema test the MCS significantly (P?0.001) reduced inflammation by 57.35 % (150 mg/kg body weight) and 72.06% (250 mg/kg body weight) in comparison to the standard drug, indomethacin (79.41%) at the end of 5h. MCS was also screened for DPPH scavenging activity, total antioxidant capacity, reducing ability as well as total phenolics content to assess its antioxidant potential. Total phenolic content and total antioxidant capacity of MCS were found to be 262.31 mg/g equivalent of gallic acid and 267.2 mg/g equivalent of ascorbic acid, respectively. The IC50 of free radical scavenging of DPPH was 13.06 ?g/ml while that of standard ascorbic acid was 13.17 ?g/ml. The reducing power of MCS was found to be concentration dependent.Bangladesh Pharmaceutical Journal 18(2): 169-173, 2015

Ethanol Extracts

The Dayak tribe are the indigenous people of West Kutai, East Kalimantan, Indonesia, and they have experiences in using plants for traditional medicine and the commonly used plants include Baccaurea macrocarpa (Miq.) Müll.Arg., Entada phaseoloides (L.) Merr., Goniothalamus macrophyllus (Blume) Hook.f. & Thomson, Gynura crepidioides Benth., Helicia robusta (Roxb.) R. Br var. robusta, Litsea elliptica, Pogostemon cablin (Blanco) Benth, and Rhodomyrtus tomentosa (Aiton) Hassk. Therefore, the present study aimed to analyze these plant species for their phenolic content, and antioxidant, antibacterial, anti-tyrosinase, and anticancer activities. The total phenolic content and total antioxidant capacity were analyzed using Folin-Ciocalteu reagent and the phosphomolybdenum method, respectively. The antioxidant activities were evaluated by DPPH and ABTS assays. The antibacterial activity was determined by agar well diffusion and microdilution methods against six bacterial strains. The anticancer activity of the plant extracts was assayed against MDA-MB-231 human breast cancer cells. Based on the ethanol extraction, the highest yield was obtained from L. elliptica (10.42%), while H. robusta extract contained the highest phenolic content, antioxidant capacity, and antioxidant activities. All the extracts exhibited antibacterial activities against all the tested strains of bacteria, with the highest activity found in R. tomentosa extract, which also showed the highest activity against the cancer cells. The ethanol extract from E. phaseoloides exhibited tyrosinase inhibition activity (IC50 = 543.83 ± 51.06 µg/mL). The results herein suggested that the ethanol extracts from some medicinal plants from East Kalimantan have potential as antioxidant, antibacterial, anticancer, and anti-tyrosinase agents.

Antioxidant activities of wampee peel extracts using five different solvents (ethanol, hexane, ethyl acetate, butanol and water) were determined by using in-vitro antioxidant models including total antioxidant capability, 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity, reducing power, and superoxide scavenging activity. Ethyl acetate fraction (EAF) exhibited the highest antioxidant activity compared to other fractions, even higher than synthetic antioxidant butylated hydroxyl toluene (BHT). In addition, the EAF exhibited strong anticancer activities against human gastric carcinoma (SGC-7901), human hepatocellular liver carcinoma (HepG-2) and human lung adenocarcinoma (A-549) cancer cell lines, higher than cisplatin, a conventional anticancer drug. The total phenolic content of wampee fraction was positively correlated with the antioxidant activity. This is the first report on the antioxidant and anticancer activities of the wampee peel extract. Thus, wampee peel can be used potentially as a readily accessible source of natural antioxidants and a possible pharmaceutical supplement.

Phenolic And Flavonoid

Honey is a well-known natural sweetener and is rich in natural antioxidants that prevent the occurrence of oxidative stress, which is responsible for many human diseases. Some of the biochemical compounds in honey that contribute to this property are vitamins and phenolic compounds such as phenolic acids and flavonoids. However, the extent to which these molecules contribute towards the antioxidant capacity in vitro is inconsistently reported, especially with the different analytical methods used, as well as other extrinsic factors that influence these molecules’ availability. Therefore, by reviewing recently published works correlating the vitamin, total phenolic, and flavonoid content in honey with its antioxidant activities in vitro, this paper will establish a relationship between these parameters. Based on the literature, vitamins do not contribute to honey’s antioxidant capacity; however, the content of phenolic acids and flavonoids has an impact on honey’s antioxidant activity.

The present study consisted in evaluating the antioxidant, anti-inflammatory and cytoprotective properties of ethanolic extracts from three mint species (Mentha spicata L. (MS), Mentha pulegium L. (MP) and Mentha rotundifolia (L.) Huds (MR)) with biochemical methods on murine RAW 264.7 macrophages (a transformed macrophage cell line isolated from ascites of BALB/c mice infected by the Abelson leukemia virus). The total phenolic, flavonoid and carotenoid contents were determined with spectrophotometric methods. The antioxidant activities were quantified with the Kit Radicaux Libres (KRLTM), the ferric reducing antioxidant power (FRAP) and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays. The MS extract showed the highest total phenolic content, and the highest antioxidant capacity, while the MR extract showed the lowest total phenolic content and the lowest antioxidant capacity. The cytoprotective and anti-inflammatory activities of the extracts were quantified on murine RAW 264.7 macrophages treated with 7-ketocholesterol (7KC; 20 µg/mL: 50 µM) associated or not for 24 h and 48 h with ethanolic mint extracts used at different concentrations (25, 50, 100, 200 and 400 µg/mL). Under treatment with 7KC, an important inhibition of cell growth was revealed with the crystal violet test. This side effect was strongly attenuated in a dose dependent manner with the different ethanolic mint extracts, mainly at 48 h. The most important cytoprotective effect was observed with the MS extract. In addition, the effects of ethanolic mint extracts on cytokine secretion (Interleukin (IL)-6, IL-10, Monocyte Chemoattractant Protein (MCP)-1, Interferon (IFN)-ϒ, Tumor necrosis factor (TNF)-α) were determined at 24 h on lipopolysaccharide (LPS, 0.2 µg/mL)-, 7KC (20 µg/mL)- and (7KC + LPS)-treated RAW 264.7 cells. Complex effects of mint extracts were observed on cytokine secretion. However, comparatively to LPS-treated cells, all the extracts strongly reduce IL-6 secretion and two of them (MP and MR) also decrease MCP-1 and TNF-α secretion. However, no anti-inflammatory effects were observed on 7KC- and (7KC + LPS)-treated cells. Altogether, these data bring new evidences on the potential benefits (especially antioxidant and cytoprotective properties) of Algerian mint on human health.
