Then, water (2 mL) was added, and the resulting mixture extracted with EtOAc (2 mL), The organic phase was collected, dried with anhydrous MgSO4, and the solvent evaporated to afford an oil (0.202 g), which was subjected to column chromatography using DCM/MeOH as eluent of increasing ...
When I see the starting materials disappear on TLC, I do 3 extraction in EtOAc and then I dry the organic phase with MgSO4. At the end of this process, normally I purify on reverse phase the crude, and and sometimes at the NMR I see the product that I want, but the yield is 5-...

Of the original sediment, an equivalent of 2 g of dry sediment was placed in a 100‐ml Teflon® microwave tube. For the aerobic degradation and/or Tenax extraction, the sediments were first separated from the medium by centrifugation (10 min, 4,000 rpm); thereafter, the pellet was added...

MgSO4alone is what becomes the dissolved solid. MgSO4makes around 49% of the MgSO4·7H2O (you can calculate it using molar masses of the elements), the rest - 51% - is water. MgSO4dissociates into Mg2+and SO42-- the latter is so called polyatomic anion, it is quite stable and do...

A. ursinum has been also reported to be a rich source of phenolic compounds (up to 27.9 g GAE (gallic acid equivalent)/ 100 g) [5]. Similar to organosulfur compounds, it was found to contain steroidal saponins that are also commonly found in the Allium genus [1,6]. Other identified ...
