Cytotoxic, anti-inflammatory and antioxidant activities of four different extracts of Galega officinalis L (Goatâs rue)
Purpose: To evaluate the cytotoxic, anti-inflammatory and antioxidant activities of four different solvent extracts obtained from the aerial parts of Galega officinalis L.Methods: The hexane, DCM, methanol and water extracts of G. officinalis were successively obtained by soxhlet extraction method. The cytotoxic activity of the extracts was assessed against human lung carcinoma (A-549), human colorectal adenocarcinoma (HT-29), human brain glioblastoma (U-87), and colon adenocarcinoma (DLD-1) by Resazurine test. The antioxidant activity of extracts were determined by Folin-Ciocalteau, oxygen radical absorbing capacity (ORAC), and 2â.7â-dichlorofluorescin-diacetate (DCFH-DA) cell-based assay while their anti-inflammatory activity was determined by nitric oxide (NO) assay.Results: DCM extract showed strong cytotoxic activity against lung adenocarcinoma and brain glioblastoma cell lines, with IC50 (concentration inhibiting 50 % of cell growth) values of 11 ± 0.4 and 16 ± 3 ÎŒg/mL, respectively. The hexane extract showed moderate anticancer activity against the same cell lines (59 ± 13 and 63 ± 16 ÎŒg/mL, respectively). DCM extract also showed significant anti-inflammatory activity, inhibiting NO release by 86.7 % at 40 ÎŒg/mL in lipopolysaccharide (LPS) - stimulated murine RAW 264.7 macrophages. Of all test extracts, the methanol extract of G. officinalis showed the highest antioxidant activity with 2.33 ± 0.09 ÎŒmol Trolox/mg , 7.10 ± 0.9 g tannic acid equivalent (TAE), and IC50 of 44 ± 4 ÎŒg/mL.Conclusion: The findings of this study suggest that DCM extract may possess anticancer effect against lung adenocarcinoma and brain glioblastoma, as well as serve as an anti-inflammatory agent.Keywords: Galega officinalis L, Biological activity, Bioassay, Anticancer, Lung adenocarcinoma, Brain glioblastoma, Goatâs ru
THE EFFECTS OF OXIDATIVE STRESS ON PHENOLIC COMPOSITION AND ANTIOXIDANT METABOLISM IN CALLUS CULTURE OF COMMON DAISY
Background: Exogenous pretreatment of oxidative stress on callus cultures of Bellis perennis L. (common daisy) induced catalase
(CAT), superoxide dismutase (SOD), total phenolic, total flavonoid, total protein and selected commercial phenolic compounds
production and accumulation.
Materials and Methods: The callus culture obtained from B. perennis pedicel explants was incubated on Murashige and Skoog
medium (MS) containing 10 mM H2O2 or 0 mM H2O2 (for control group) for 10 hours. Twenty phenolic compounds (apigenin,
caffeic acid, p-coumaric acid, gallic acid, genistein, kaempferol, luteolin, myricetin, procyanidin-C1, quercetin, rutin hydrate,
vanillic acid, ferulic acid, salicylic acid, sinapic acid, chlorogenic acid, hesperedin, naringenin, rosmarinic acid and isorhamnetin)
were detected by LC-ESI-MS/MS analysis in methanolic extracts of 10 mM H2O2 and control treatments.
Results: A predominant phenolic compound was chlorogenic acid followed by rutin hydrate, caffeic acid, luteoline, isorhamnetin,
quercetin, myricetin, apigenin, p-coumaric acid and kaempferol. No gallic acid, genistein, procyanidin-C1, vanillic acid, sinapic
acid, hesperidin and naringenin were detected in H2O2 treatment and control groups of B. perennis. The total phenolic contents
estimated were in the order of H2O2 treatment (285.36 ÎŒg/g dw) and control (220.79 ÎŒg/g dw) groups. The biosynthesis and
accumulation of kaempferol, myricetin, quercetin and isorhamnetin were only determined in H2O2 treatment callus materials. The
H2O2 pretreatment clearly showed in a raise in enzymatic and non-enzymatic antioxidant activities. Finally, a significant positive
correlation between phenolic accumulation and comprehensive activities of CAT, SOD, total phenolic, total flavonoid and proline
was accessible.
Conclusion: The present results suggest that using H2O2 as an elicitor or a stimulant plays a significant enhancement role in special
phenolic molecules biosynthesis and activation of antioxidant metabolism on callus cultures of B. perennis
Antiproliferative Activity of Some Medicinal Plants on Human Breast and Hepatocellular Carcinoma Cell Lines and their Phenolic Contents
Purpose: To determine the phenolic composition and antiproliferative activity of 16 different extracts (hexane, dichloromethane, methanol and water) obtained from Bellis perennis, Convolvulus galaticus, Trifolium pannonicum and Lysimachia vulgaris on human breast cancer (MCF-7) and human hepatocellular carcinoma (HepG2/C3A) cell lines.Methods: The aerial parts of the plants were successively extracted with hexane, dichloromethane, methanol and water using a Soxhlet apparatus. The phenolic content of the plants were determined by plants by high performance liquid chromatography (HPLC) while their antiproliferative activity was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide, a yellow tetrazole (MTT) assay.Results: Among the tested extracts, the methanol extract of B. perennis showed the best antiproliferative activity against MCF-7 cell line with IC50 (inhibiting 50 % of cell growth) value of 71.6 ÎŒg/mL. Furthermore, the dichloromethane extract of C. galaticus showed the best anti-proliferative activity against HepG2/C3A cell line with IC50 of 57.3 ÎŒg/mL. The HPLC data for the plant extracts showed the presence of the following phenolic compounds: gallic acid monohydrate, caffeic acid, rutin hydrate, luteolin-7-O-ÎČ-D glucoside, kaempferol, myricetin, quercetin, coumarin and apigenin.Conclusion: The findings of this study indicate that there is some justification for the use of B. perennis and C. galaticus as traditional anticancer medicinal herbs.Keywords: Bellis perennis, Convolvulus galaticus, Trifolium pannonicum subsp. elongatum, Lysimachia vulgaris, MCF-7, HepG2/C3A, Phenolics, Breast cancer, Antiproliferativ
EVALUATION OF ANTIBACTERIAL, ANTITUMOR, ANTIOXIDANT ACTIVITIES AND PHENOLIC CONSTITUENTS OF FIELD-GROWN AND IN VITRO-GROWN LYSIMACHIA VULGARIS L.
Background: Lysimachia vulgaris L. (Yellow loosestrife) is a medicinal plant in the family Myrsinaceae. It has been used in the
treatment of fever, ulcer, diarrhea and wounds in folk medicine. It has also analgesic, expectorant, astringent and antiinflammatory
activities. Two different sources of the plant (field-grown and in vitro-grown) were used to evaluate the biological
activities (antibacterial, antitumor and antioxidant) of L. vulgaris. In vitro-grown plant materials were collected from L. vulgaris
plants that were previously regenerated in our laboratory.
Materials and Methods: Plant materials were extracted with water, ethanol and acetone. For antibacterial test, disc diffusion
method and 10 different pathogenic bacteria were used. Antioxidant activity was indicated by using DPPH method. The total
phenol amount by using Folin-Ciocaltaeu method and the total flavonoid amount by using aluminum chloride (AlCl3) colorimetric
method were determined.
Results: Generally, yellow loosestrife extracts demonstrated antibacterial activity against Gram-positive bacteria (Staphylococcus
aureus, S. epidermidis and Streptococcus pyogenes). Strong antitumor activity of yellow loosestrife was observed via potato disc
diffusion bioassay. Nine different phenolics were also determined and compared by using High-Performance Liquid
Chromatography (HPLC).
Conclusion: Future investigations should be focused on fractionation of the extracts to identify active components for biological
activity

Abstract Number â 48: Cerebral Sinus Venous Thrombosis Secondary to Chronic Inflammatory Disorders in Children
Introduction Cerebral Sinus Venous Thrombosis (CSVT) is a rare form of venous thromboembolism that can lead to significant morbidity and mortality predominantly in young people. While previous literature has identified prothrombotic and infectious pathologies as significant risk factors for CSVT, chronic systemic conditions such as connective tissue diseases (CTD) are less studied. The purpose of the current study is to describe the clinical features, neuroimaging characteristics, treatment, and longâterm neurological outcomes in children with CSVT secondary to CTD. Methods We reviewed electronic medical records of patients under 18 years of age diagnosed with CSVT secondary to CTD between 2002â2018 in a single center. We analyzed data regarding demographics, comorbidities, neuroimaging and neurological examination findings during the initial encounter. Subsequent longâterm followâup neurological examinations, lab and imaging workup, and medical management was also analyzed. Results Eight patients (Male:Female: 6:2) met the criteria and were included in the analysis. The patientâs age ranged from 6 weeks to 17 years. CTDs include Behcetâs (n = 2), Kawasaki (n = 1), systemic lupus erythematosus (n = 1), Wegener granulomatosis (n = 1), sarcoidosis (n = 1), and inflammatory bowel disease (n = 1). Five patients had a normal neurological examination on initial presentation, two had papilledema, and one had hypotonia and poor suck reflex. On initial neuroimaging, the most common thrombosis locations were transverse sinuses (n = 7). All patients received antiâthrombolytic therapy (heparin, warfarin, or Lovenox) between 2.5 to 6 months. Three patients had complete resolution and one had partial resolution of thrombosis on followâup neuroimaging (average = 4.3 months, range 3â8 months). On longâterm clinical followâup (average: 41.3 months, SD: 62.1), all patients had normal neurological examinations. Conclusions Our case series demonstrated that 50% of patients with CSVT secondary to CTD showed full/partial resolution of thrombosis on followâup neuroimaging. In addition, they also had good clinical outcomes on longâterm clinical followâup with anticoagulation or antithrombotic treatment. This study uncovers the favorable outcomes of CSVT associated with CTD in children, but more cohort studies are required in order to make accurate conclusions
<em>In vitro</em> antibacterial and antitumor efficiency of some traditional plants from Turkey
50-58Traditional usages of medicinal plants can be justified scientifically with bioassays. Three different extracts (aqueous, methanol and ethanol) of 11 Turkish traditional plants [Mentha longifolia (L.) L., Lamium album subsp. crinitum (Montbret & Aucher ex Benth.) Mennema, Sideritis taurica Steph. ex Willd., Hypericum perforatum L., Hypericum linarioides Bosse, Cyanus triumfettii (All.) DostĂĄl ex Ă. Löve & D. Löve, Daphne oleoides Schreb., Anemone nemorosa L., Polygonatum orientale Desf., Cynoglossum montanum L. and Hyoscyamus niger L.] were evaluated for their antibacterial and antitumor potentials. Antibacterial activity was evaluated with 3 Gram-positive (Staphylococcus aureus, Staphylococcus epidermidis and Streptococcus pyogenes) and 7 Gram-negative (Serratia marcescens, Salmonella typhimurium, Pseudomonas aeruginosa, Proteus vulgaris, Klebsiella pneumonia, Enterobacter cloacae and Escheria coli) bacteria by using disc diffusion method. Ethanol and methanol extracts of S. taurica, and all extracts of H. perforatum and H. linarioides showed the best antibacterial activities against tested Gram-positive bacteria. Aqueous extract of L. album displayed the best inhibition against Streptococcus pyogenes. Antitumour potential was revealed with Agrobacterium tumefaciens-induced potato disc tumor assay. Strong antitumor activity was observed with ethanol and methanol extracts of L. album (90 % and 80 %, respectively). This study ascertained the scientific rationale behind the traditional knowledge of S. taurica, H. perforatum, H. linarioides, L. album and D. oleoides. Identification of active components should be investigated for plant extracts having strong antibacterial and antitumor activities in further studies.</em
