isolation and structure elucidation of a new alkaloid from the indonesian blue-green alga arthrospira platensis

a new alkaloid (1) and two known compounds (2 and 3) were isolated from the blue-greenalga arthrospira platensis. their structures were determined on the basis of spectroscopic data.according to the obtained data and values in the literature, the compounds were concluded to beeckol.

Isolation and Structure Elucidation of Three New Dolastanes from the Brown Alga Dilophus spiralis

Three new dolastane diterpenes (1-3) and five previously reported perhydroazulenes were isolated from the organic extracts of the brown alga Dilophus spiralis. The structure elucidation and the assignment of the relative configurations of the isolated natural products were based on extensive analyses of their spectroscopic data, whereas the absolute configuration of metabolite 2 was determined ...

Hepato-Protective Effects of Blue-Green Alga S. platensis on Diclofenac-Induced Liver Injury in Rats

Introduction: This research aimed at evaluating the hepato-protective effect of the alga Spirulina platensis against diclofenac-induced liver injury in rats. The study’s ultimate aim was to understand whether Spirulina could be developed as a functional food for therapy and protective therapeutic use. Methods: Hepatic injury was induced by administering diclofenac sodium (50mg/kg i.p.) for 5 da...

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...

Isolation and structure elucidation of coumarin and cinamate derivatives from Lycium ruthenicum

Lycium species is a popular medicinal plant in the traditional Chinese medicine and Lycium ruthenicum is a native medicinal plant of Iran. Lycium genus has several biologically important properties too. Investigation of chemical composition of ethyl acetate extract of this plant is the goal of this study. Two coumarins (Scopoletin and Sculetin) and Methyl-2-hydroxy-4-undecanoxy-trans-cinamate w...
