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.
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Seitomycin: isolation, structure elucidation and biological activity of a new angucycline antibiotic from a terrestrial Streptomycete.
A new antibiotic, named seitomycin (1c), and the known microbial metabolite tetrangulol methyl ether (2) were found in the ethyl acetate extract of two terrestrial Streptomyces sp. isolates. The structure of the new antibiotic was elucidated by spectroscopic studies and by comparison of the NMR data with the structurally related hatomarubigin C (1a) and SM-196 B (1b). Seitomycin (1c) showed mod...

متن کاملIsolation and structure elucidation of new antibiotics related to angolamycin.
Angolamycin (1) and two novel analogues (2 and 3) were isolated from the culture broth of a Streptomyces strain. NMR and MS analysis proved that 2 is the 18-dihydro-, while 3 is the 18-deoxo-18-dihydro derivative of angolamycin. Full experimental assignment of the 1H and the 13C NMR spectra of these compounds was obtained from 1D and 2D chemical shift correlation measurements. Compounds 2 and 3...
