Abstract
ABSTRACT The objective of this ongoing research is to investigate and assess the aqueous extracts, vegetable oil, and residual plant components derived from O. dillenii by use of HPLC, and GC-MS. Subsequent investigations employed colorimetric techniques to identify reducing and soluble sugars. We developed and validated an energy-dispersive X-ray fluorescence (EDXRF) method for determining the concentrations of essential chemical elements (O, C, Ca, Mg, K, S, P) in seeds, juice, and peel, as well as their residues. HPLC analysis yielded results indicating that extracts from O. dillenii seeds, juice, and peel from distinct regions (Oujda, Nador, and Essaouira) contained elevated concentrations of metabolites. Specifically, peel and juice extracts exhibited the highest levels of organic acids and betanin compared to O. dillenii seeds. Conversely, seed oils displayed a noteworthy tocopherol content, predominantly δ-tocopherol. Similarly, an examination of organic acid composition in juice, peel, and seeds from three different regions revealed their elevated levels. Citric acid and oxalic acid emerged as predominant components in the juice. Overall, Opuntia dillenii’s physicochemical and phytochemical characterization improves in understanding its potential as a bioactive chemical promoter, which could lead to the creation of new medicinal medicines or functional food ingredients.
