Xanthylium Cation Extraction Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
SPE was carried out using multimode cartridges CHROMABond C18 ec (Macherey-Nagel GmbH & Co. KG, Düren, Germany) consisting of an octadecyl-modified silica gel with a bed volume of 10 g. The method is based on the extraction procedure of George et al. [23 (link)]. The cartridges were conditioned with 120 mL ethanol and then equilibrated with 120 mL ultrapure water obtained from a Synergy purification system (Millipore, Molsheim, France). The sample (30 mL) was loaded onto the cartridges. The xanthylium cations were collected during this step. The cartridges were then washed with 120 mL of water, followed sequentially by 120 mL of 5% and 7.5% aqueous ethanol solutions, and 70 mL of 25% aqueous ethanol solution. The ethyl esters of the xanthylium cations were then eluted with 50 mL of 40% ethanol. The solvents were evaporated after SPE and the residue was subsequently lyophilized.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
