| 2 | Phenolic extract from Ocimum basilicum restores lipid metabolism in Triton WR-1339-induced hyperlipidemic mice and prevents lipoprotein-rich plasma oxidation显示文摘In this study we investigated the hypolipidemic and anti-lipoprotein-oxidation activities of phenolic extract from sweet basil a popular culinary herb.The hypolipidemic activity was studied in mice model injected intraperitoneally with Triton WR-1339 at a dose of 200 mg/kg body weight.The animals were grouped as follows:normolipidemic control group(n=8),hyperlipidemic control group(n=8)and phenolic extract-treated group(n=8)at a dose of 200 mg/kg body weight.After 7 h and 24 h treatment,the oral administration of the phenolic extract exerts a significant reduction of plasma total cholesterol,triglycerides and LDL-cholesterol concentrations(P<0.001).On the other hand,we demonstrated that the phenolic extract prevents plasma lipid oxidation by 16%(P<0.001),20%(P<0.001),32%(P<0.001)and 44%(P<0.001)at a doses of 10,25,50 and 100g/mL,respectively.The results were compared with ascorbic acid used as standard synthetic antioxidant.HPLC analysis shows that the extract contains 4 major phenolics and is especially rich in rosmarinic acid.This finding indicates that the phenolic extract might be beneficial in lowering hyperlipidemia and preventing atherosclerosis. | Ilham Touiss Saloua Khatib Oussama Bekkouch Souliman Amrani Hicham Harnafi | 2017 | Food Science and Human Wellness2017，6，1： | 1 |
| 3 | Anti-inflammatory, anticoagulant and antioxidant effects of aqueous extracts from Moroccan thyme varieties显示文摘Objective: To evaluate the anti-inflammatory, anticoagulant and antioxidant effects of aqueous extracts of thyme varieties from Moroccan.Methods: The aqueous extracts of tree medicinal plants [Thymus atlanticus(T. atlanticus), Thymus satureioides and Thymus zygis(T. zygis)] were screened for their antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl radical-scavenging, ferric reducing antioxidant power assay, radical scavenging activity method, the inhibition of 2,2'-azobis(2-amidinopropane) dihydrochloride that induces oxidative erythrocyte hemolysis and thiobarbituric acid reactive substances assay. The anti-inflammatory activity of aqueous extracts was evaluated in vivo using croton oil-induced ear edema and carrageenan-induced paw edema in mice and rats, respectively. This extracts were evaluated in vitro for their anticoagulant activity at the different concentrations by partial thromboplastin time and prothrombin time activated. Results: All thyme varieties were found to possess considerable antioxidant activity and potent anti-inflammatory activity in the croton oil-induced edema. Administration of aqueous extracts of two varieties(50 mg/kg)(T. zygis and T. atlanticus) reduced significantly the carrageenaninduced paw edema similar to non-steroidal anti-inflammatory drug(indomethacin, 10 mg/kg). In partial thromboplastin time and prothrombin time tests, T. atlanticus and T. zygis extracts showed the strongest anticoagulant activity. In contrast, Thymus satureioides did not show the anticoagulant activity in these tests. Conclusions: All aqueous extracts possess considerable antioxidant activity and are rich in total polyphenol and flavonoid but they act differently in the process of inflammatory and coagulation studied. This study shows great variability of biological activities in thyme varieties. | Tarik Khouya Mhamed Ramchoun Abdelbassat Hmidani Souliman Amrani Hicham Harnafi Mohamed Benlyas Younes Filali Zegzouti Chakib Alem | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，8： | 1 |

| 10 | Attenuation of coda waves in the SW of High-Atlas area, Morocco显示文摘We investigate attenuation scattering and loss properties in Souss basin(SW of High-Atlas) as a transition zone between the High and Anti Atlas ranges. This district consists in a thinned crustal patch with shallow seismicity and loose sedimentary trenches that perform an important contribution to augment seismic attenuation. So far, no coda waves approach in our knowledge have been used to draw satisfying outputs about the attenuation properties in the region. Therefore, this update suggests to correlate the lateral changes of seismic attenuation to different characteristics and asperities i.e. seismic activity,crustal age and thickness, heat flow, and ground deformation rate. To do so, we analysed coda waves derived from waveform data of more than 23 local earthquakes from seven broadband seismometers recorded during 2010 e2012 period. As a starter, we utilized the backscattering model which defines theseismic attenuation as inversely proportional to quality factor by the equation A ?1=. QQcestimates c were deducted at various central frequency bands 1.5, 3.0, 6.0, 9.0, 12.0 and 18.0 Hz according to different lapses times. The estimated average frequency dependence quality factor gives relation Qc? 120 f1;01,while the average Qcvalues vary from 149 at 1.5 Hz to 1895 at 18 Hz central frequencies. We observed an intimate dependence between quality factor and frequency ranges, which reflects the complexity of geological/geophysical pattern in the Souss basin and the presence of a variety of heterogeneities within the underlying crust. | Roumaissae Azguet Ghizlane Bouskri Youssef Timoulali Mimoun Harnafi Younes EL.Fellah | 2019 | Geodesy and Geodynamics2019，10，4： | 0 |
| 11 | Investigation of antioxidant and antihemolytic properties of Thymus satureioides collected from Tafilalet Region,south-east of Morocco显示文摘Objective:To examine the antioxidant and antihemolytic activities of the aqueous extract,total polyphenols and total flavonoids of Thymus satureioides(T.satureioides).Methods:This plant was collected from Tafilalet Region of Morocco.The aqueous extract was obtained by cold maceration,and the components were obtained by Soxhlel extraction using solvents of varying polarity.The identification and quantification of phenol(caffeic and rosmarinic acids) and llavones(luteolin 7-glycoside and hesperetin) were carried out by high performance liquid chromatography analysis.Results:Total polyphenol and flavonoids contents in the aqueous extract of T.satureioides were(456.73±6.94) mg caffeic acid equivalent/g of dry plant and(172.79±2.12) mg rutin equivalent/g of dry plant,respectively.Different extracts showed good antioxidant activity.IC_(50)for 1.1-diphenyl-2-picrylhydrazil radical scavenging activity was(0.480±0.010),(0.418±0.005),(43.S91 ±2.467) and(0.510±0.010) mg/niL for the aqueous extract,total polyphenol,flavonoids and trolox,respectively.Also,the extracts showed ferric reducing antioxidant power and the values were(50.79±2.02),(117.51±6.46).(7.03±0.29) and(44.33±7.55) mmol trolox/g for the aqueous extract,total polyphenol,flavonoids and trolox.respectively.Serum levels of malondialdehyde was significantly decreased in comparison with the oxidized control(P<0.00l).They showed good activity against 2.2.-azobis 2-amidinopropane dihydrochloridc induced hemolysis in erythrocytes of rabbit blood.In addition,they ameliorate the half time of hemolysis.Conclusions:Our results provide evidence that aqueous extract,total polyphenols and total flavonoids of T.satureioides exhibit marked antioxidant and antihemolytic activities,thus confirming and justifying the popular uses of this plant to relieve some pains. | Mhamed Ramchoun Khalid Sellam Hicham Harnafi Chakib Alem Mohamed Benlyas Farid Khallouki Souliman Amrani | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，2： | 0 |
