Ward Taifi (Taif rose) is considered one of the most important economic products Taif, Saudi Arabia. In this study both fresh and dry Taif rose were biologically phytochemically investigated. The 80% methanol extracts and<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mi>n</mml:mi></mml:mrow></mml:math>-butanol fractions had high radical scavenging activity toward artificial 1,1-diphenyl picrylhydrazyl (DPPH) • with SC 50 values range 5.86−12.24 µg/ml whereas...
Trichinellosis, a zoonosis caused by the genus Trichinella, is widespread foodborne disease. Albendazole, one of benzimidazole derivatives, used for treating human trichinellosis, but with limited efficacy in killing encysted larvae and numerous adverse effects. Cyperus rotundus L. herbal plant wide range medicinal uses, including antiparasitic, frequently traditional medicine to treat various illnesses.LC-ESI-MS was identify active phytoconstituents methanol extract (MeOH ext.) aerial parts...
Determination of antioxidant and antimutagenic activities Phlomis armeniaca Mentha pulegiumOnder YUMRUTAS, Saadet D. SAYGIDEGER
The use of plants and their derived substances increases day by for the discovery new therapeutic agents owing to versatile applications. Conocarpus erectus L. (family Combretaceae) is one two species in genus widely spread Taif other parts Kingdom Saudi Arabia. It used some countries as folk remedy anemia, catarrh, conjunctivitis, diabetes, diarrhea fever. To our knowledge from literatures there little work about phytochemical contents biological activities C. which encouraged authors carry...
Oriental Journal of Chemistry is a peer reviewed quarterly research journal pure and applied chemistry. It publishes standard papers in almost all thrust areas current chemistry academic commercial importance. provides platform for rapid publication quality papers, reviews letters. abstracted indexed reputed National International agencies.
Abstract Background The Convolvulus genus is distributed all over the world and has a long history in traditional medicine. As nanotechnology expands its reach into areas like drug delivery biomedicine, this study intends to assess potential of arvensis L. extracts as anti-bacterial, anti-inflammatory anti-cancer agents, along with chemical profiling methanolic (MeOH) extract active ingredients. Methods composition an 85% MeOH was investigated by liquid chromatography electrospray source...
In the present study, antioxidant activity of methanolic extracts leaves seven Egyptian Cassia species was investigated using two methods, phosphomolyb-date method and 1,1 diphenyl-2-picrylhydrazyl radical (DPPH) scavenging method.· The results revealed that C. glauca is most potent other plant decreases in following order: grandis > nodosa fistula didymobtrya occidentalis sophera. Defatted extract active subjected to fractionation different organic solvents such as CHCl3, EtOAc BuOH....
Rosa damascena Miller var. trigintipetala Dieck (Taif rose) is considered as one of the most important economic products Taif governorate, KSA. In this study, different components rose essential oil were characterized using GC-MS technique. addition, in vitro cytotoxic, genotoxic and anticancer effects investigated toward normal human peripheral blood lymphocytes two kinds cancer cell lines; HepG2 MCF7. analysis showed that acyclic monoterpene alcohols had highest content (254.7 mg/g oil)....
Essential oils of aromatic plants as an important phytochemical class have been recognized for many years a great source pharmaceutical agents and food additives. There are factors influencing the chemical composition essential including extraction techniques. In this project, effect methods (hydrodistillation, microwave assisted hydrodistillation solvent free extraction) Mentha longifolia L. growing in Taif, KSA on yield their were investigated. addition, anticancer antimicrobial activities...
Recently, the residues or by-products of agriculture industry take attention for their valuable source natural antioxidants. Taif rose (Rosa damascena trigintipetala Dieck) is considered one most important economic products Taif, Saudi Arabia. In this study, antioxidant and total phenolic contents defatted flowers fresh were investigated. The activity was chemically determined using three methods; 1,1-diphenyl picrylhydrazyl (DPPH.) free radical scavenging activity, phosphomolybdenum method...
On the bases of ethnomedicinal and random plant collection approaches for searching out new pharmacologically bioactive agents, 45 Egyptian species belonging to 25 families were collected, methanol extracts (52) assayed in vitro their antischistosomal antimicrobial activities. Only Curcuma longa L. (Zingiberaceae) Nerium oleander (Apocynaceae) lethal Schistosoma mansoni worms after a 24-h incubation period culture medium at concentration up 100 μ g/mL. The different successive organic C....
Introduction: Cisplatin is a highly effective chemotherapeutic agent; its clinical use severely limited by serious side effects as nephrotoxicity. The aim of this study to evaluate the nephroprotective activity defatted methanolic extract two Egyptian plants: Lantana camara and Cucurbita pepo certain fractions derived from L. on cisplatin-induced nephrotoxicity in rats. Also, identification chemical constituents HPLC-ESI- MS. Methods: Nephrotoxicity was induced rats single dose cisplatin....
The methanol extract of the leaves Buddleja asiatica Lour. (Loganiaceae) showed antioxidant activity toward well known in vitro tests such as total capacity by phosphomolybdenum method, free radical scavenging 1,1- diphenyl-2-picrylhydrazyl assay (DPPH assay) and hydrogen peroxide methods. Due to high n-butanol successive fraction DPPH H 2 O (SC 50 = 11.99 18.54 μg/ml, respectively), this was subjected chromatographic separation isolation. Four non-phenolic compounds were isolated identified...
The aim of this study was to characterize the chemical composition some volatile components, in vitro antimicrobial and anticancer activity essential oil n-hexane extract from Trachyspermum ammi L. (Family Apiaceae). samples obtained by GC-MS analysis, evaluated disc diffusion method whereas sulphorhodamine method. Twenty-three monoterpenoide compounds were identified which four compounds; -terpinene, thymol, P-cymene -pinene major components with quantity 266.28, 201.97, 194.91 38.49 mg/g...
