Factors such as the bee species, season, and geographical location can influence the composition of BV
A total of 14 HPLC fractions were collected, separated from solvent in vacuum, the residue of each fraction was suspended in H 2 O (10 mL), freeze-dried twice and, then, screened for the target compounds showing the pseudomolecular ions m/z 453 and 837, respectively, by means of UPLC-TOF MS using the following chromatographic conditions (0.3 mL/min, 40 C): starting with a mixture of H 2 O/MeOH (40/60, v/v), the MeOH content was kept constant for 1 min at 60%, increased to 90% within 8 min, increased to 95% within 10 min, increased to 100% within 1 min, kept constant for 1 min, decreased within 1 min to 60% MeOH, followed by re-equilibration for 1 min
Back in San Pedro de Atacama, we will make a stop at the Putana River, where we will be able to see the beautiful landscape of the Putana River, where we can observe the native flora and fauna that inhabit this place
