Hola @LatinXChem ! Hello, presenting my work "Quantification of damnacanthal in organic extracts of Morinda citrifolia by High Performance Liquid Chromatography (HPLC)" in #LatinXChem24 #LatinXChemAna #Ana58

[David Cáceres @davidcaceres_mx]

It may not look like it in the picture but I am excited to participate as a judge in the upcoming #LatinXChem24 on October 14 & 15. We would be happy to have your contribution. Register now. You have until September 15th. https://t.co/K3tEODdGbd

@munoz_rdd @LatinXChem Hola, gracias por su pregunta. Para todas las extracciones utilicé DCM. En las imágenes incluyo las condiciones del análisis cromatográfico así como los parámetro de las extracciones.

@WaldmanLab @TheChemMixt @LatinXChem Ultrasound: EAU
Microwave: EAM
Reflux: ECR
Soxhlet: ES
Maceration: EM
As can be seen, the one with the highest amount of damnacanthal is not necessarily the one with the highest proportion of extract. So the "best" method depends on the purpose.

@WaldmanLab @TheChemMixt @LatinXChem Hello, thank you very much for your inquiry. The conditions reported in the literature were used, however, when using conventional methods and methods assisted by some equipment, there are some important differences between them as shown in the table.
