Eman A. Ibrahim, Alaa A. Gaafar, Zeinab A. Salama, Farouk K. El Baz
Abstract
The potency of Solenostemma argel (asclepiadaceae) as anti-inflammatory and antioxidant effects was investigated. Three solvent extract were used for extracting (polyphenolic, flavonoids and tannins) from the leaves of Solenostemma argel (S. argel). Three complementary antioxidant systems: (DPPH∙ free radical scavenging, Fe2+-chelating and iron reducing power as well as the total phenolic, total flavonoids and total tannins contents of the extracts were also investigated. In-vitro anti-inflammatory effects of S. argel were assessed by using albumin denaturation assay. Our findings indicated that S. argel acetone extract exhibits greater scavenging activity than those extracted by other solvents. The same trend was achieved by using Fe2+-chelating and reducing power. The results revealed that the aqueous, acetone and ethanol extracts of S. argel showed anti-inflammatory activity (74.19%, 69.44% and 66.58%) respectively by inhibiting the heat induced albumin denaturation. The outcomes from HPLC study showed that acetone extract from S. argel had the highest amounts of e-vanillic, benzoic, pyrogallol, chlorogenic and ellagic acids. Whereas, rosmarinic, quercetrin and narengin acids were the major flavonoid compounds in S. argel acetone extract. The obtained results showed that, the solvent plays a vital role in the extraction of the plant constituents and S. argel is a very promising source of bioactive compounds. From the results obtained, it could be concluded that flavonoids and related polyphenols present in the S.argel extract may be responsible for the antioxidant and anti-inflammatory activities which may be attributed to the radical scavenging and anti-inflammatory effects of some of their active constituents.

Abstract
Keloid occurred by abnormal wound healing, characterized by massive fibroblast proliferation and excessive collagen accumulation. Therapy for keloid is relatively limited and mostly has side effects. Tithonia diversifolia has widely been studied for having anti-proliferative effect against some cancer cells in vitro. This study was conducted to assess T. diversifolia potential as an antifibrotic agent. Antifibrotic activity of standardized ethanolic extract of T. diversifolia leaf on cell proliferation of keloid fibroblasts and its collagen accumulation were expressed by IC50 values using probit regression analysis. Keloid fibroblast proliferation inhibition percentage was elevated gradually along with the given doses of T. diversifolia extract with very strong correlation (r=0.838;p=0.000 in 72 hours; r=0.924;p=0.000 in 120 hours of incubation) with the lowest IC50 value 3.624 µg/mL in 120 hours incubation time. There was also significant time-dependent effect (p=0.005). As well for collagen accumulation with moderate correlation (r=-0.797;p=0.000 for 72 hours incubation time; r=-0.583;p=0.000 for 120 incubation time) with lowest IC50 value 2.280 µg/mL in 120 hours incubation time. This study concluded that the ethanol extract of T. diversifolia is potential to be developed as antikeloid in the future although some additional data such as toxicity and clinical study

Abstract
The present study aimed to evaluate the antifungal activities of Acacia ataxacantha against six strains of Aspergillus and the acute toxicity of hydroalcoholic extract in rat models. Five extracts including hexane, dichloromethane, ethyl acetate, methanol and mixture of water/methanol of A. ataxacantha’s barks were evaluated against six Aspergillus strains using agar diffusion method and counting of number fungal spores. Oral acute toxicity at a dose of 2000 mg/kg was conducted as per Organization for Economic Co-operation and Development (OECD) 423 guidelines. Results obtained showed that all the extracts inhibited mycelial growth and sporulation of fungi with percentages of inhibition ranging from 5.37- 53.02% and 33.77 to 99.70% respectively. The antifungal activity of the extracts at the same concentration is more marked on the sporulation of fungi. Ethyl acetate and dichloromethane extracts exhibited the most significant antifungal activity. In the acute toxicity evaluation, all animals were physically active and no deaths of rats were observed during the test. No significant change was observed in body weight, haematological and biochemical parameters of treated rats compared with controls. The histopatological analysis of liver and kidney showed normal architecture suggesting no morphological disturbances. The overall finding of this study suggests that A. ataxacantha inhibited the mycelial growth and sporulation of Aspergillus strains. Equally, hydroalcoholic extract of this plant is non-toxic up to 2000 mg/kg body weight. Thus, A. ataxacantha could be used as an antifungal.

Abstract
The aim of the study was to analyze chemical composition and inhibitory potential of leaf and flower extracts of Mimusops elengi L. against the enzymes α-amylase, α-glucosidase and acetylcholinesterase. Inhibitions of these enzymes are considered to be effective in controlling diabetes and memory function. Methanol extracts of leaves and flowers were tested against the enzymes α-amylase, α-glucosidase and acetylcholinesterase. Chemical composition in both the extracts were analysed by GC-MS, after derivatization. Leaf extract had stronger activity against the enzyme α-glucosidase than the flower extract. But the flower extract showed higher activity against the enzymes α-amylase and acetylcholinesterase. Total 41 components (7 organic acids, 9 sugars, sugar alcohols and sugar acid, 5 amino acids, 6 fatty acids, 8 phenols, 2 flavonoids, 1 inorganic acid, porphine, phytol and phenylethylamine) could be identified from both the extracts. The flower extract contained lesser metabolites both qualitatively and quantitatively. The study suggests potential beneficial effects of the extracts which needs further analysis in vivo for bioactivity and for identification of active constituents.

F. Sidaoui, S. Belghith Igueld, D. Barth, M. Trabelsi-Ayadi, J.K. Cherif
Abstract
This work was undertaken to explore the potential of extract of leaves Nettle (Urtica dioica L.) of Tunisia as sources of minerals and natural antioxidants. Two extraction methods were used and compared, the supercritical fluid extraction (SFE) with carbon dioxide (CO2) and traditional maceration extraction using ethanol (EtOH) as solvent. The SFE was explored at various operating conditions of pression (15 and 18 MPa) and temperature (40 and 60°C) (with or without glass beads). The phenolic and flavonoid contents were determined respectively by Folin-Ciocalteu and Aluminium chloride colorimetric method. The ABTS assay was used for determining the antioxidant activity. The protein assay was performed by the Kjeldahl method and the multielemental analysis by atomic emission spectrometry with inductively coupled plasma. The results show some variations between both extracts in terms of extraction yield and antioxidant activity. The SFE, with carbon dioxide (SC-CO2) is an interesting alternative to the conventional extraction using organic solvents. However, higher values of phenolic content (11.62 mg GAE.g-1 DW), flavonoid content (7.10 mgCE.g-1DW) and antioxidant activity TEAC (8.11 μM) correspond to extracts obtained by maceration. In all SFE extract assays, the highest yield was reached at 60°C – 15MPa with glass beads (2.5%). The ICP analysis shows the abundance of Urtica dioica L. in calcium (1116 mg.100g-1DW) and magnesium (544). The protein assay showed high content (15.75 %.). The present study indicates that the leaves of Urtica dioica L. of Tunisia are a potential source of minerals, proteins and antioxidants

Abstract
The ischemic stroke caused by thrombosis of the arterial vessels is a growing concern of this world right now. Present treatment for this disease is not satisfactory for all. That is why we aim to run this study with herbal preparations, as because we know herbal preparations are safe enough than any others. An in vitro thrombolytic model was used to check the clot lysis effect of the crude extracts of four Bangladeshi plants, which are, Crotalaria retusa, Crotalaria alata, Crotalaria prostrata and Crotalaria verrucosa. Streptokinase here was used as a positive control and water as a negative control. In short, venous blood withdrawn from twenty healthy volunteers was allowed to form clots that were weighed and treated with the test plant materials to disrupt the clots. Weight of clot after and before treatment provided a percentage of clot lysis. Through this model we got plants like C. retusa and C. prostrata showed highest significant potency, 39.16 ± 9.52% and 37.85 ± 7.74%, respectively compared with positive control standard streptokinase (79.55 ± 9.09%) and negative control distilled water (7.41 ± 2.76%). Other extracts showed moderate clot lysis activity, C. alata and C. verrucosa respectively lysis clots 31.63 ± 6.60% and 35.88 ± 8.94%. Our study suggests that thrombolytic activity of C. retusa and C. prostrata could be considered as very promising and beneficial for the Bangladeshi traditional medicine and should be proceed for further study regarding this activity.

Abstract
The present study was planned to evaluate and compare the in-vivo antipyretic activity of aqueous, hydroalcoholic, methanolic and petroleum benzene extracts of leaves of Allophylus cobbe (L.) Raeusch. in endotoxin (Lipopolysaccharide from E. coli serovar 0127: B8) induced pyretic models in adult Wistar rats of either sex. Acute oral toxicity study was conducted as per OECD guidelines. Preliminary phytochemical analysis as per standard procedures and HPTLC fingerprinting of the various extracts was done using solvent hexane: ethyl acetate. In vivo antipyretic activity was determined by LPS induced pyrexia model and oral administration of 250 mg/kg of various extract of A. cobbe and lipopolysaccharide at dose rate of 50µg/kg intramuscularly. The reduction in temperature of aqueous extract treated group was comparable to the standard antipyretic drug paracetamol by the second hour of study. No acute toxic symptoms were observed on oral administration of any of these extracts at 2000 mg/kg body weight which indicated the safety of extracts. Phytochemical analysis revealed the presence of secondary plant metabolites like as phenolics, alkaloids, glycosides, tannins, terpenes and flavonoids. The HPTLC chromatogram and densitometry of different leaf extracts of A. cobbe at visible, short and long UV revealed maximum no of peak 13 in petroleum ether extract followed by 6 peaks in aqueous, 7 peaks in hydroalcoholic and methanolic extract respectively. The results of the study indicated that the antipyretic response observed could be due to the presence of one or more components of polar nature. Further fractionation and isolation study needs to be undertaken for identifying the active compound responsible for the antipyretic activity of the extract and development of potent safe herbal antipyretic drug from this plant.
