در مطالعه حاضر، توانایی دو گونه جلبک ماکروسکوپی enteromorpha intestinalis و sargassum angustifolium در تجمع زیستی فلزات سنگین نیکل، کادمیم، مس و سرب و امکان استفاده از محتوای کلروفیل آنها به عنوان شاخص استرس فلزی مورد مطالعه قرار گرفت. نمونه های جلبک و رسوب از 4 ایستگاه ساحلی در محدوده استان بوشهر و در طی دو فصل سرد (بهمن ماه 1387) و گرم (تیر ماه 1388) جمع آوری گردید. فلزات سنگین با کمک اسیدنیت...
sea algae are widely consumed in the world. there are several seaweeds including brown algae which are authorized for human consumption. these plants contain important phytochemical constituents and have various potential biological activities. the present study investigated the presence of phytochemical constituents and total phenolic quantity of the seaweeds sargassum angustifolium , sargassu...
The aerial parts of H. perforatum subsp. perforatum and H. perforatum subsp. angustifolium were investigated for their chemical composition and antimicrobial activity. Spectrophotometric analysis indicated that H. perforatum subsp. perforatum is richer in flavonoids and tannins than the other subspecies. HPLC analysis confirmed the higher yield of flavonoids in H. perforatum subsp. perforatum a...
Epilobium sp. are commonly used in traditional medicine in the treatment of early stages of benign prostatic hyperplasia and inflammation. It is suggested that a dominating constituent, oenothein B, is responsible for the extracts therapeutic effects. Several bioactivities were established for extracts and oenothein B in various in vitro models, but due to the questionable bioavailability of th...
Polyploid species generally occupy harsher habitats (characterized by cold, drought and/or high altitude) than diploids, but the converse was observed for Chamerion angustifolium, in which diploid plants generally inhabit higher altitudes than their polyploid derivatives. Plants at high altitudes may experience cold-induced water stress, and we therefore examined the physiological responses of ...
The antimicrobial activity and phenolic compounds of five Finnish honey products against important human pathogens Streptococcus pneumoniae, S. pyogenes, Staphylococcus aureus, and methicillin-resistant S. aureus were analyzed. Microbroth dilution method and HPLC-DAD were used in antimicrobial testing and phenolic compound determination, respectively. Significant antimicrobial activity (p < 0.0...
Over the period 2006–2010, 40 species of primary parasitoids belonging to eleven genera were found and reared from 50 species of host aphids, from a total of 106 host plants collected from 62 localities all around Slovenia. Over 230 tritrophic associations have been reviewed, including four associations which are reported for the first time; Ephedrus plagiator/ Staticobium limonii/ Limonium ang...
this study represents the first report on the chemical composition and biological activity of trifolium angustifolium var. angustifolium. the major components of the essential oil were identified as hexatriacontene (23.0%), arachidic acid (15.5%) and α-selinene (10.0%). the main constituents of the fatty acid obtained from the petroleum ether extract were identified as palmitic acid (29.8%), li...
The antimicrobial activity of the Epilobium angustifolium, E. hirsutum, E. palustre, E. tetragonum and E. rosmarinifolium ethanolic extracts was studied in vitro on Gram-positive and Gram-negative bacteria, yeasts and fungi. The cytotoxicity of the extracts was also evaluated using the Artemia salina test. All the extracts showed antimicrobial activity in a range of concentrations between 10 an...
