The present study was aimed to optimize the protocol for the synthesis of silver nanoparticles using aqueous extracts of Sargassum swartzii (Turner) C.Agardh and evaluate cytotoxic potetnials using brine shrimp bio-assay activity and Trypan blue dye exclusion method. The reduction of pure Ag+ ions was monitored by measuring the UV-Vis spectrum of the solution at 200-900 nm using Shimadzu spectr...

The aim of this study was to investigate the in vitro cytotoxic activity of total extract of MeOH (70%) and partition fractions of hexan, chloroform (CHCL3), ethylacetate (EtOAc) and MeOH-H2O of brown algae species (Sargassum swartzii, Cystoseira myrica, Colpomenia sinuosa) found in the Persian Gulf against in different cell lines including HT-29, Caco-2, T47D, MDA-MB468 and NIH 3T3 cell lines ...

OBJECTIVES The objective of this study was to evaluate larvicidal activity of native marine algae against main malaria vector Anopheles stephensi. STUDY DESIGN The total 70% methanol (MeOH) extract and partition fractions of chloroform (CHCl3), ethylacetate (EtOAc), and MeOH from two algae, Sargassum swartzii and Chondria dasyphylla were investigated for larvicidal activities against late III...

six species of sargassum c. agardh (sargassaceae) with compressed primary branches, including: s. binderi sonder, s. aquifolium (turner)c. agardh, s. oligocystum montagne, s. swartzii (turner)c. agardh, s. crassifolium j. agardh and s. cristaefolium c. a. agardh, were identified in the persian gulf and oman sea coasts, among which s. binderi is reported as newly recorded species in iran for the...
