Abstract

This study aimed to identify the secondary metabolite compounds present in the ethanol extract of Plukenetia volubilis L. (sacha inchi) shells through phytochemical screening and LC-MS analysis. The extraction was performed using the maceration method with 95% ethanol as solvent, resulting in a yield of 47.33%. Qualitative phytochemical tests revealed the presence of alkaloids, flavonoids, tannins, terpenoids, saponins, and glycosides in the extract. Further LC-MS analysis tentatively identified several phenolic and flavonoid compounds with known biological activities, including sinapinic acid, 1-o-sinapoylglucose, and azelaic acid from the dicarboxylic acid group. The presence of these compounds highlights the potential of sacha inchi shell extract as a natural antioxidant and antidiabetic agent. These findings support the valorization of sacha inchi agricultural waste as a promising raw material for pharmaceutical and nutraceutical applications.
