摘要： In this study, ultra-high performance liquid chromatography-tandem mass spectrometry was used to isolate and identify terpenoids in three types of pineapple fibers (pineapple leaf fiber, pineapple stem fiber, and pineapple root fiber). The research results showed that in the positive and negative ion modes, 9 and 26 terpenoid compounds were identified from the three types of pineapple fibers, totaling 35 species in 12 categories, among which triterpene saponins had the largest number of species. Pineapple root fiber contains the highest total terpenoid content, followed by pineapple stem fiber and leaf fiber. In the OPLS-DA model, the VIP and S-plot methods revealed the differences in terpenoid compounds in three pineapple fibers. The research results showed that there were 9, 8 and 7 significantly different terpenoid compounds in pineapple leaf fiber and pineapple stem fiber, pineapple leaf fiber and pineapple root fiber, and pineapple stem fiber and pineapple root fiber respectively. Functional terpenoids such as ivy saponin, dehydroabietic acid, myrcene and ginsenoside are distributed in different parts of pineapple with varying degrees of enrichment. This study provides a basis for differentiated utilization and value-added use of pineapple leaves, stems and roots. Utilization provides scientific basis.
