Using thin-layer chromatography (TLC) bioautography, a total of 58 extracts from various organs (aerial parts, leaves, flowers, fruits, roots) of 16 Turkish plants were tested for their antibacterial, antifungal, acetylcholinesterase inhibitory, antioxidant, and radical scavenging activities. The hexane, CHCl3/CH2Cl2, water, and total MeOH extracts were used. No activity was observed against tw...

The bark of Chamaecyparis lawsoniana (A. Murray) Parl. was extracted with methanol and sequentially partitioned with n-hexane, ethyl acetate, n-butanol and deionized water. The antioxidant activities of the four extracts were evaluated using the DPPH• and ABTS methods. The total phenolic content of the extracts was determined using the Folin-Ciocalteu method and expressed as gallic acid equival...

The aim of the present study was to isolate cyanobacteria from oil refinery waste water and detection of antagonistic activity of their extracts on four species of pathogenic bacteria. The cyanobacterium was isolated and purified on Blue green algae medium number 11 (BG-11) medium. Methanol and water extracts prepared from the cultured cyanobacterium after 45 days growth on BG-11 medium. The bi...

Extracts from the plants Plantago lanceolata and P. rugelii were evaluated for toxicity to the root-knot nematode Meloidogyne incognita, the beneficial microbes Enterobacter cloacae, Pseudomonas fluorescens and Trichoderma virens, and the plant-pathogenic fungi Fusarium oxysporum f. sp. gladioli, Phytophthora capsici, Pythium ultimum, and Rhizoctonia solani. Wild plants were collected, roots we...

In our previous studies, we showed the inhibitory effects of Punica granatum L. flower and Rhus coriaria L. fruit water extracts on dental plaque accumulation by several bacteria, especially Streptococcus mutans (S. mutans), on orthodontic wire by in-vitro assays. In this study, the anti-cariogenic properties of the extracts were evaluated by assessing their effects on expression of glycosyltra...

background & aim: the purpose of present study was to examine and validate the folk's claim of inhalation of monechma ciliatum seeds powder by traditional african natives for cold and allergic conditions, so as to formulate a useful therapeutic agent to respiratory tract infections. experimental: different extracts were bio-assayed in vitro for their bioactivity to inhibit the growth of pat...

The perchlorate anion (ClO4-) is an anthropogenic contaminant of increasing concern in water supplies, and has been shown to disrupt thyroid activity. Most perchlorate analyses are currently carried out by ion chromatography (IC) with suppressed conductivity detection (SCD). While this procedure has been demonstrated to provide acceptable performance for analysis of water samples, the determina...

the introduction of acacia saligna in the north nile delta of egypt is causing harmful impacts on the plant diversity. thirty stands were established in both invaded and non-invaded areas. the species abundance and diversity were determined. soil samples were collected and analyzed. the correlation between vegetation and soil variables was investigated. the allelopathic potential of water and m...

Adiantum capillus veneris is a medicinally essential plant used for the treatment of diverse infectious diseases. The study of phytochemical and antimicrobial activities of the plant extracts against multidrug-resistant (MDR) bacteria and medically important fungi is of immense significance. Extracts from the leaves, stems, and roots of Adiantum capillus veneris were extracted with water, metha...

The antimicrobial activity as well as phytochemical screening of the hexane, acetone, methanol and water extracts of Clematis brachiata Thunb (Ranunculaceae) leaves was investigated. The agar dilution assay method was used for the evaluation of the antimicrobial activity of extracts against 10 bacteria and four fungal species. The phytochemical screenings were performed by using the standard pr...
