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...

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 Novel Compound from Leaves of Derris Trifoliate

In the present work, leaves of mangrove plant, Derris trifoliata was successively extracted with methanol and for characterization, the leaf extract was subjected to thin layer chromatography and high performance thin layer chromatography. Different compounds were isolated and the structure of one particular compound was elucidated by NMR, IR, UV and GC-MS spectra.
