  • Antiproliferative and antioxidant potential of methanol extracts of aerial
           parts of Colchicum boissieri and Colchicum balansae

    • Authors: Mehlika ALPER
      Abstract: The antiproliferative and antioxidant activities, and total phenolic, flavonoid, and tannin contents of methanol extracts obtained from the aerial parts of Colchicum boissieri and Colchicum balansae were investigated in the present study. The evaluation of the antiproliferative effects of the extracts under study was carried out using the MTT assay. The antioxidant potentials of the extracts were assigned by using several assays (FRAP, CUPRAC, DPPH, ABTS, and β-carotene). The antiproliferative effects of both extracts on Caco-2 cells appeared to be generally similar for the incubation times tested. The antioxidant potential was found to be higher in the extract of C. boissieri (FRAP: on average 1.39 mg TE/g, CUPRAC: on average 10.06 mg TE/g, DPPH: on average IC50= 0.59 mg/mL, ABTS: on average IC50= 0.267 mg/mL, β-carotene: on average 78.58%) than the extract of C. balansae. In terms of total phenolic, flavonoid and tannins contents, C. boissieri extract (on average 1.97 mg GAE/g, 8.65 mg QE/g and 4.75 mg CE/g, respectively) was determined to be richer than C. balansae extract. The results suggest that both extracts have some biological properties for pharmaceutical applications. Further studies may contribute to the use of these plants for various purposes such as natural antioxidant sources or cancer agents.

  • The therapeutic effects and antioxidant properties of epigallocatechin-3
           gallate: A new review

    • Authors: Seda BEYAZ; Özlem GÖK, Abdullah ASLAN
      Abstract: The aim of this review is to investigate the possible protective and preventive effects of epigallocatechin-3 gallate (EGCG) in terms of human health including hepatoprotective, neuroprotective, cardioprotective, nephrotoxicity and anticancer effects. Green tea is one of the most consumed beverages in many countries, especially in Turkey and it plays protective roles in the treatment of various diseases via the polyphenol it contains. It is known that EGCG, which is the main bioactive polyphenol in green tea, has versatile bioactivities. It has been determined that EGCG has the highest free radical scavenging ability among common phenolic compounds. It regulates gene expression and molecular signaling pathways by inhibiting oxidative stress and inflammation. In addition, it prevents cell death by suppressing cytokine production and neutrophil migration in inflammatory diseases. With the studies conducted in the last decade, it has been determined that EGCG has anticancer, antioxidative, antiinflammatory, antidiabetic, antitumor, antihypertensive and neuroprotective activities. Especially, its anticancer effect has been found to have chemopreventive and chemotherapeutic activities in various cancer types such as colon, lung and breast cancer with in vivo and in vitro studies conducted to investigate molecular targets. This review was written to examine the possible protective and preventive effects of EGCG in terms of human health, including its hepatoprotective, neuroprotective, cardioprotective, nephrotoxicity and anticancer effects.

  • Antioxidant Activities and Chemical Composition of Essential Oil of
           Rhizomes of Zingiber officinale (Ginger) and Curcuma longa L.(Turmeric)

    • Authors: Ümit ERDOĞAN
      Abstract: This study aimed to determine the essential oil volatile components of ginger and turmeric rhizomes, as well as to determine the total antioxidant capacity of essential oil samples according to the CUPric Reducing Antioxidant Capacity (CUPRAC), ferric reducing antioxidant potential (FRAP) method and free radical scavenging activities of oil samples and standards such as BHA, BHT, and Trolox were determined using a DPPH method. Essential oil analysis of volatile components was also performed on a Shimadzu GCMS-QP2010 SE (Japan) model with Support Rx-5Sil MS capillary column (30 m x 0.25 mm, film thickness 0.25 μm). Antioxidant capacities of essential oils were evaluated according to the CUPRAC method in millimole Trolox/gram -oil equivalent. GC-MS analysis of ginger showed the presence of 5 major peaks identified as Curcumene (13.46%), Zingiberene (33.92%), α-Farnesene (8.07%), β-Bisabolene (6.39%), and β-Sesquiphellandrene (15.92 %), respectively. GC-MS analysis of Turmeric showed the presence of 3 major peaks identified as Ar-Turmerone (29.24%), α-Turmerone (22.8 %), and β-Turmerone (18.84%). CUPRAC values of calculated antioxidant capacities of essential oil samples were determined as 1.97 ± 0.102 mmolTR/g-oil for Zingiber officinale R. and 3.40 ± 0.071 mmol TR/g-oil for Curcuma longa L. The scavenging effect of turmeric, ginger and standards on the DPPH radical decreased in the order of Trolox>BHA>BHT>Turmeric>Ginger which were 95.25 ± 0.05%, 62.57 ± 0.34%, 61.6 ± 0.3%, 51.45 ± 0.59%, and 50.26 ± 0.09%, at the concentration of 150µg/mL, respectively. Additionally, it revealed that essential oils of turmeric and ginger exhibited effective ferric reducing power.

      Abstract: Objective: The aim of this study is to determine the phytochemical contents and the antioxidant activity of Helianthemum lippii (L.) Dum.Cours. crude extract.Methods: For preliminary phytochemical analysis, standard procedures were applied, while identification and quantification of individual phenolic compounds were performed by HPLC analysis. The Folin–Ciocalteu method was used to evaluate the total phenolic acid content of the plant extracts, The total flavonoid content was determined using the aluminum chloride colorimetric assay. The FTIR spectroscopy method was used to examine the chemical makeup of the organic extracts. The antioxidant activities were assessed using the 1,1-diphenyl-2-picrylhydrazyl and reducing power assays.Results: Chemical analysis revealed the presence of numerous secondary metabolites, such as polyphenols, flavonoids, tannins, saponins, anthocyanins, cardiac glycosides, leuco anthocyanins steroids, terpenoids, alkaloids, and mucilage. For the HPLC analysis, we obtained 65 peaks and we identified 6 major elements of bioactive compounds. The total concentration of polyphenols and flavonoids was varied respectively 183.12±2.84 mg gallic acid eq/g dry wt and 72.00±1.03 mg quercetin eq/g dry wt /mg. The general concentration of condensed tannin and hydrolyzable tannin compounds were expressed in terms of catechin equivalent (5.88±1.58 mg Ca eq/g dry extract) and gallic acid (2.818±0.138 mgTA eq/g dry wt) respectively. FTIR spectroscopy investigation indicated several characteristic peak values in the extract with diverse functional groups such as amide, alcohol, and phenol groups. Concerning the antioxidant activity, we found that this extract has high inhibitory percentages equivalent to IC50 3.085±0.001 for DPPH and 1.724±0.021 for reduction power (µg/mL). Conclusion: Our study proved that the aqueous extract of the H lippii is very rich in secondary metabolites; in addition, it has a tremendous anti-oxidant capacity, which leads us forward to introduce it for medical use.

  • Effect of culture time on secondary metabolite production from
           MeJA-stimulated in vitro roots of Hyoscyamus niger L.

    • Authors: Hikmet DEVECİ; Tunhan DEMİRCİ, Nilgün GÖKTÜRK BAYDAR
      Abstract: This study was conducted to determine the effects of different culture times on root growth and accumulation of secondary metabolites in adventitious roots from Hyoscyamus niger petioles. For this purpose, adventitious roots transferred to culture media containing 1 mM methyl jasmonate (MeJA) were harvested at 11 different culture times, starting from day 1 to day 30. After harvest, the fresh and dry weights of the roots and the root growth index as parameters of root growth, as well as the amounts of tropane alkaloids and phenolic compounds, were examined. It was found that the fresh and dry weights and the growth index of the roots harvested between the 12th and 30th day were the highest. The highest amounts of scopolamine were obtained from roots harvested on days 15, 18, and 21. The highest hyoscyamine accumulation was found on days 12 and 15. The highest total phenolic content was 19.33 mg g-1 in root cultures harvested on day 15. HPLC analyses revealed that ferulic acid, caffeic acid, o-coumaric acid, p-coumaric acid, rutin, and quercetin were not detected in the roots. On the other hand, the amounts of gallic acid, catechin, epicatechin, vanillin, cinnamic acid, rosmarinic acid, and chlorogenic acid showed significant changes depending on the culture times. Considering all the results, it was found that the optimum culture time for the production of secondary metabolites in H. niger adventitious root cultures stimulated with 1mM MeJA was 15 days.

  • Essential oil composition of two endemic Nepeta L. (Lamiaceae) taxa from
           Southwestern Turkey

    • Authors: Gürkan SEMİZ; Batıkan GÜNAL, Metin ARMAĞAN
      Abstract: Nepeta L. is one of the important genus in the Lamiaceae family. It includes ca. 300 herbaceous species and mostly grows in Eurasia. Nepeta is represented in Turkey by 40 taxa and of these 16 are endemic. Nepeta species are commonly utilized in traditional medicine by the local people, primarily as spasmolytic, diuretic, and bronchodilator agents. As a consequence of studies on Nepeta taxa, terpenoids and flavonoids have been identified as the most common components. In this report, chemical contents of two endemic Nepeta taxa (N. viscida from Buharkent/Aydın and N. nuda L. subsp. lydiae from Altınyayla/Burdur) were presented. The main constituents were determined as α-terpineol (20.59%), trans-β-caryophyllene (9.90%) and spathulenol (9.37%) for N. viscida, and 1,8-cineole (31.31%), borneol (18.95%) and caryophyllene oxide (14.59%) for N. nuda subsp. lydiae.

  • The Use of Organic Sun-Dried Fruits for Delivery of Phenolic Compounds

    • Authors: Gökhan DERVİŞOĞLU; Ahmet YEMENİCİOĞLU
      Abstract: The aim of this study is to characterize and increase the total soluble (water soluble + alcohol soluble) phenolic (SPCT) and flavonoid content (SFCT) and total soluble free radical scavenging based antioxidant capacity (SACT) of major sun-dried fruits such as raisins, figs, prunes and apricots. Due to their high insoluble dietary fiber content, the bound antioxidant capacity formed 61 to 67% of the overall antioxidant capacity (water soluble + alcohol soluble + bound) of sun-dried fruits. The SPCT, SFCT and SACT of sun-dried fruits changed between 1675 and 3860 µg catechin/g (d.w.), 161 and 495 µg catechin/g (d.w.) and 13 and 28.5 µmol Trolox/kg (d.w.), respectively. The incorporation of green tea polyphenols into sun-dried raisins, figs and apricots by controlled rehydration conducted in green tea extracts increased their SPCT, SFCT and SACT 1.5 to 1.8 fold, 1.3 to 1.6 fold, and 1.5 to 2.6 fold, respectively. The method applied caused limited increases in SPCT (1.1 fold) and SFCT (1.2 fold) of prunes, but it increased SACT of these fruits 1.6 fold. This study showed the possibility of using sun-dried fruits not only as source of dietary fiber, but also for delivery of phenolic compounds. The methods used in this study for delivery of green tea phenolic compounds to selected organic sun-dried fruits could be an alternative method to increase intake of these invaluable antioxidant compounds and increase functionality of sun-dried fruits which are already accepted as good source of dietary fiber.

  • Molecular Docking, Antibacterial and Antioxidant Activities of Compounds
           Isolated from Ethiopian Plants

    • Authors: Yadessa MELAKU; Tokuma GETAHUN, Markos ADDİSU, Hailemichael TESSO, Rajalakshmanan ESWARAMOORTHY, Ankita GARG
      Abstract: This study evaluated the antibacterial and antioxidant activities of the constituents of L. tomentosa and S. longipedunculata. The in-silico molecular docking analysis of the isolated compounds was also reported herein for the first time. The GC-MS analysis of the essential oil of L. tomentosa led to the identification of eleven components with 2,5-dimethoxy-p-cymene identified as the principal constituent (59.39%). Lauric acid (1), β-stigmasterol (2), chrysophanol (3), and emodin (4) were isolated from L. tomentosa using silica gel column chromatography. Likewise, 9H-xanthene-3,5-diol (5), 1,7-dihydroxy-4-methoxyxanthone (6), and oleic acid (7) were isolated from S. longipedunculata. The structures of the isolated compounds were elucidated using UV-Vis, IR, and NMR spectroscopic methods. Compounds 3 and 4 are new to the genus Laggera, while 5 and 6 are new to the species S. longipedunculata. Compounds 3-6 inhibited DPPH radical by 86, 92, 88, and 90%, respectively. Compounds 5 and 6 inhibited 79.2 and 81.9% peroxide formation, respectively. The antioxidant activities displayed by compounds 4-6 suggest their use as a natural antioxidant. Compounds 4 and 6 inhibited the growth of bacteria by 18.00±0.10 and 16.06±0.22 mm, respectively. Compounds 3, 4, and 6 showed binding affinities of −10.4, −10.4, and −9.9 kcal/mol against Staphylococcus aureus DNA Gyrase, respectively, while 4 showed −10.4 kcal/mol against human topoisomerase IIβ. Therefore, the present study results showed that emodin and 1,7-dihydroxy-4-methoxyxanthone might be considered lead compounds for further development as antibacterial and anti-cancer agents. The findings also substantiate the traditional use of these plants against bacteria.

In the study, metals and mineral analyses were carried out using dry ashing method with ICP-OES, vitamin A and vitamin E analyses were carried out using the HPLC method and vitamin C, total phenol, flavonoids, antioxidant capacity, DPPH, ABTS, hydrogen peroxide, hydroxyl radicals scavenging activity and anti-hemolytic activity of the methanol extract Lycianthes rantonnetii (L. rantonnetii) plant was determined spectrophotometrically. According to the results, Cu, Zn, Co, Mg, retinol, -tocopherol, ascorbic acid, total antioxidant activity, phenolic and flavonoid contents of L. rantonnetii were 57.60  4.83 mol/kg, 0.14  0.01 mmol/kg, 2.23  0.10 mol/kg, 39.13  1.76 mmol/kg, 12.22 ± 3.37 μmol/kg, 104.55 ± 7.44 μmol/kg, 80.61 ± 9.31 mg/100 g, 11.45 ± 0.60 mM ascorbic acid/g, 5.33 ± 0.41 mg GA/g and 3.76 ± 0.29 mg QE/g, respectively. The results of this study showed that the content of antioxidant vitamins, minerals of the L. rantonnetii plant was at high levels and it contains a reasonable amount of total phenol, and flavonoids also, it was determined that the plant had a high scavenging activity for free radicals. It is believed that L. rantonnetii can be used as an additive for food products in the various food sectors with appropriate antioxidant activities.
