Prosthechea karwinskii is an endemic orchid of Mexico with significant value for its traditional uses: ornamental, ceremonial, and medicinal. The pharmacological activity this plant has been studied using specimens recovered from religious use during Holy Week in Oaxaca, Mexico, sourced various localities within state. Geographical variability can influence the chemical composition plants, as environmental factors affect production their secondary metabolites, which impact biological properties. This research evaluated leaves pseudobulbs P. obtained different comprising 95-790 g 376-3900 fresh material pseudobulbs, respectively, per locality. Compounds were identified UHPLC-ESI-qTOF-MS/MS following ultrasound-assisted hydroethanolic extraction. Twenty-one compounds twenty pseudobulb. findings revealed differences across between species. Roaguia locality exhibited highest extraction yield potential leaves. For Cieneguilla showed yield, El Lazo had lowest but potential. study represents first comprehensive analysis variation a native Mexican orchid. In all localities, contained known activity, validating species medicine highlighting medical applications.
