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...
متن کاملIsolation 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...
متن کاملIsolation 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.
متن کاملISOLATION AND STRUCTURAL ELUCIDATION OF THE FIRST KNOWN C-HOMOPROTOBERBERINE
A novel C-homoprotoberberine alkaloid, Hediamine (2), has been isolated from the roots of Berberis actinucantha (Berberidaceae). Conclusive proof for the structure of hediamine was obtained by its comparison with the isomeric lactam (4), by chemical transformation, and by means of spectroscopic techniques (UV, IR, MS, NMR).
