Isolation, Characterization and Antiproliferative Activity of Secondary Metabolites from Tanacetum alyssifolium (Bornm.) Grierson

Isolation of secondary metabolites from Pseudomonas fluorescens and its Characterization

Twenty Pseudomonas fluorescens strains were isolated from rice growing soil samples and characterized. One of the P.fluorescens isolated and identified from the dual culture test. It was fermented for secondary metabolite in a small scale and extracted with ethyl acetate. The isolated metabolite tested against rice fungal pathogens. The structure of the compound was elucidated by high-resolutio...

Isolation and Structure Elucidation of Secondary Metabolites from Echinophora platyloba DC from Iran

Background: Echinophora platyloba DC (Apiaceae) is one of the two endemic species of Echinophora genus in Iran. It has many folkloric uses and several biological activities but there is no information about its phytoconstituents. Objective: In this work some of the secondary metabolites were isolated, purified and identified from n-hexane, ethyl acetate and methanol extracts from the aerial pa...

Activity-guided investigation of antiproliferative secondary metabolites of Asteraceae species

Isolation and characterization of phytochemicals of Johrenia paucijuga (DC.) Bornm.

Background and objectives: The genus Johrenia belongs to Umbelliferae family and contains five species that are endemic to Iran. Johrenia paucijuga grows widely in the north-west, west and center of Iran. So far, there has been no research about phytochemistry of J. paucijuga. In the present study, phytochemicals of the plants have been isolated and their structures h...

Isolation and identification of secondary metabolites from the aerial parts of Stachys lavandulifolia Vahl

Stachys lavandulifolia Vahl is an herbaceous wild plant native to Iran which is traditionally used in Iranian folk medicine as a mild sedative tea for reducing anxiety and for treatment of gastrointestinal disorders. Our previous study on ethyl acetate extract of S. lavandulifolia proved anti-anxiolytic activity and so the present study was designed to determine chemical components of this biol...
