The present invention relates to novel lipopeptide compounds, pharmaceutical compositions of these compounds and methods of using these compounds as antibacterial compounds. The compounds of the invention are particularly useful against a variety of bacteria, including resistant strains. The compounds are useful as antibacterial agents against
Clostridium difficile.
A method for the isolation of delta-9-tetrahydrocannibinol (THC) from, Cannabis plant material, wherein delta-9-THC Acid and THC are separately obtained comprising the steps of extracting the Cannabis plant material, chelating delta-9-THC acid on alumina solid support from cannabis extracts rich in the acid washing of non-acid components of the extract with organic solvents and eluting of the delta-9-THC acid with strong polar solvents.
The method also includes a process by which to increase the THC content and decrease the weight of Cannabis extracts or residue from distillation of Cannabis extracts containing a low concentration of THC, comprising treatment of such materials with water-missible organic solvents followed by filtration and evaporation of the solvent to obtain the concentrated residue.
