Abstract. This work describes a photodegradation catalyst, for water organic contaminants in visible light,
based on curcumin (a natural dye) sensitized TiO2 (anatase) nanoparticles. Phenazopyridine (a pharmaceutically active gradient) was used as a contaminant. A 400 nm, and shorter, cut of filter was used to confirm only visible light was used in photodegradation process with no UV radiation. The catalyst system was characterized by electronic absorption spectroscopy and XRD. The particle size forthe catalyst nanaprticles was calculated using Scherrer equation and found to be ~45 nm in average. Different reaction parameters were studied, such as effect of contaminant concentration, amount of loaded catalyst, and pH value on the photodegradation rate. Turn number (T.N.) and quantum yield (Q.Y.) values were calculated for comparative assessment of the catalyst effeciency. The results show the ability of curcumin dyes to sensitize TiO2 anatase nanoparticles in photodegradation phenazopyridine under visible radiation.
Key words: Curcumine; sensitization; photo-degradation; phenizopyridine; Anatase TiO2.
1. Introduction Different catalyst systems were suggested for photo-degradation of organic contaminants in water, using ultra violet radiations [1-4]. Despite the advantages of such photocatalyst systems, they demand UV rather than the freely abundant visible light. Because only a small fraction of UV exists in the arriving solar radiation [5, 6], researchers focus their efforts to sensitize their catalyst systems on visible solar light[7-14]. The most commonly used semiconductor in photo-degradation processes is the nano-sized titanium oxide TiO2, by virtue of its stability to photo corrosion, low cost, abundance, safety and high photo-catalytic activity [4, 15-18]. Dye-sensitized TiO2 particles were investigated in both light-to-electricity conversions (Graetzel cells) and in photodegradation processes [13, 14]. Different types of dyes are known including ruthenium complexes, CdS nano-particles and others [11, 19-22]. Natural dyes extracted from plants were also widely reported as sensitizers for TiO2 particles in Graetzel cells. Examples of such dyes are chlorophyll derivatives, natural porphyrines, anthocyanins, and curcumin which exist in molecular form [23-28]. Unlike the case with solar cells, natural dyes have been used to a far lesser extent as sensitizers in water purification 127

Abstract. Aqueous and ethanolic extracts of Mentha pulegium L. (Lamiaceae) from two different locations Tizi-Ouzou and Bejaia in Algeria were examined in vitro. Phenolic compounds and antioxidant activity were analyzed. Measurement of total phenolic and total flavonoids contents of the extracts of M. pulegium were achieved by using Folin-Ciocalteu and chloride aluminium methods, respectively. The total phenolic content of water extract from Tizi-Ouzou location was found significantly higher (55.78 2.78 mg GAE/g DW). The flavonoids content was also higher in the extracts from this location for both ethanolic and water extracts (2.17 0.12; 2.04 0.03 mg QE/g DW, respectively). Antioxidant activities were assessed by five in vitro antioxidant assays. Results showed that the two M. pulegium provenances were significantly different according to their antioxidant activity. Indeed, aqueous extract issued from Bejaia plant exhibited stronger antioxidant activity. For instance, Bejaia provenance shoots showed lower IC50 value of 20.35 μg/ mL for H2O2 test. Key words: Pennyroyal extracts; Antioxydant activity; Bejaia location, Tizi-Ouzou location.
1. Introduction Mentha pulegium L. (Algerian name: Fliou) is one of the most frequently used Algerian herb, its aerial part is considered effective in treating a wide range of disorders, mainly for the treatment of flatulent dyspepsia and intestinal colic due to its carminative and antispasmodic properties (Dellile, 2007). Its essential oil and dry parts have been traditionally used in medicine (digestive, liver and gallbladder disorders, amenorrhea, gout, colds, increased micturition, skin diseases and abortifacient), gastronomy (culinary herb), aromatherapy and cosmetics. Recent research reported its antioxidant and antimicrobial properties (Teixera et al., 2012). The occurrence of at least some of mentioned above diseases as well as aging processes may result from oxidative stress leading to a variety of alterations within the human organism caused by reactive oxygen species (ROS). ROS is a collective term used to include both the 138

Abstract. The separation of enantiomers of great interest to the pharmaceutical, chemical and food industries. This work has focused on studying the properties of chiral HPLC separation of some mono-and bis-heterocyclic derivatives Hesperetin possessing a stereogenic center in position 2. The chiral separation of these molecules was performed by HPLC using two chiral stationary phases derived polysaccharides (Chiralcel OJ, Chiralpak IA) and various mobile phases (alkane / alcohol). The Chiralpak IA column showed a better enantioseparation using methanol alone as polar mobile phase. In addition, these compounds have undergone antibacterial tests. The majority of compounds have an inhibitory overlooked all the microorganisms tested power. The antioxidant activity overlooked the DPPH have been shown that these derivatives showed a very important activity of free radicals. Key

1. Introduction Much of the current research interest focuses on the study of chiral molecules such as flavanons. Due to their polyphenolic structure, these compounds have health-related properties, which are based on their antioxidant activity as well as anticancer, antiviral and anti-inflammatory activities [1, 2]. Among the different types of flavanones most studied, we are interested in this work on Hesperetin [5,7-dihydroxy-2-(3'-hydroxy-4'-methoxyphenyl) chroman-4-one] is a flavanone obtained by the hydrolysis acid of hesperidin. Hesperetin and its glycoside is also mainly present in citrus fruits. The aglycone is less dominant in nature than the glycoside. The most widely distributed glycoside of hesperetin is hesperidin, which is conjugate with rhamnosyl-β-1,6-glucose. Hesperidin (hesperetin-7-rutinoside) is present in higher extents in lemons, limes, sweet oranges, tangerine and tangor species of citrus fruits [3]. The flavanone Hesperetin is a chiral molecule exists in two enantiomeric forms due to the presence of an asymmetric carbon at position 2 [4], and it shows significant reactivity centers allowing him heterocyclic derivative formation [5]. It has in its structure two important 170

Abstract. Allelopathic activity study of 15 plant’s aqueous extracts was evaluated on the germination and
growth of two experimental models, Lactuca sativa and Rhaphanus sativus. The seeds tested were germinated in petri dishes with increasing concentration: 0.25; 0.5 ; 0.75 and 1 % of plant extract. Seasonal variation of allelopathic activity of Tetraclinis articulata was studied. Fractionation assay by liquid-liquid partitioning was also undertaken for the same species. In parallel of this biological activity test, phytochemical screening of the main phytoconstituents was established by TLC with quantification of phenolics and flavonoïds contents. Inhibitory effects with variable intensities were observed on the germination and growth of L. sativa. Aqueous extract of T. articulata was exhibited the more inhibitory effect on L. sativa germination while aqueous extract of Peganum harmala showed the more growth inhibitory effect with all concentrations tested, for the two experimental models. Investigation of seasonal variation revealed that June and November samples of T. articulata presented the most important inhibitory effect on L. sativa germination. Phytochimical screening by TLC identified that these active extracts contain phenolic acids, flavonoïds, cardiotonic glycosids, sesquiterpens lactons and saponins. Phenolics and flavonoïds contents quantified by spectrophotometry were very important in some active extracts like Globularia alypum, Pistacia lentiscus, Acacia raddiana and Haloxylon scoparium.

Abstract. Bee pollen is a fine powder-like material produced by flowering plants pollen, mixed with nectar and bee secretions and gathered by the honey-bees. Pollens are the male reproductive cells of flowers and bees' primary food source, containing concentrations of phytochemicals and nutrients and rich in secondary metabolites. It is known that bee pollen contains lipids, sugars, proteins, amino acids, flavonoid and phenolic acids such as caffeic acid and gallic acid. The aim of our study is to evaluate caffeic and gallic acids from different sorts of bee pollen from Algeria using an HPLC method. Analysis of caffeic acid, and gallic acid was realized with the chromatographic column VPODS RP18 type and using a gradient of mobile phase (Acetonitril- 0,1% acetic acid) and spectrophotometric detection. Caffeic acid in the range from 24.734 to 42.182 µg/g and gallic acid from 0.321 to 0.406 mg/g was determined in tested pollen samples. Key Words: Bee pollen, HPLC, phenolic acids, caffeic acid, gallic acid.
INTRODUCTION Bee pollen has been used for many years in both traditional medicine and supplementary nutrition, as well as in alternative diets, mainly due to its nutritional properties and health benefits. Bee pollen is the result of the agglutination of flower pollens; it is made by worker honey bees with nectar and salivary substances and stored at the hive entrance [1]. The collection of bee pollen is a relatively recent development, dependent primarily on the basic concept of scraping pollen off of the bees’ legs as they enter the hive. When analyzing and studying the nutritional and therapeutic properties of bee pollen, modern science has made it possible to specify its valuable antimicrobial [2], antifungal [3], antioxidant [4], anti-radiation [5], hepatoprotective [6], chemopreventive [7], anticancer [8] and antiinflammatory activities [9]. 190
