UHPLC-MS/MS Profiles of Resin Glycosides in Nine Sweet Potato Cultivar Leaves

128 tentatively identified resin glycosides from nine sweet potato cultivars, including Shangshu 19, Xuzi 20-1, and Blackheart. The data includes pancreatic lipase inhibitory activity measurements, expressed as Orlistat equivalents, for cultivar extracts. The dataset was authored by Yi Lin and last updated on March 19, 2026.

Use Cases

• Identify cultivar-specific resin glycoside profiles based on UHPLC-Q-TOF-MS/MS analysis
• Correlate structural features with pancreatic lipase inhibition based on Orlistat equivalent measurements
• Select sweet potato cultivars for agriceutical development based on multivariate analysis results
• Study the structure-activity relationship of pentasaccharide resin glycosides based on identified marker compounds

Strengths

• Includes pancreatic lipase inhibitory activity data for nine cultivars, with specific Orlistat equivalent values (e.g., 2.44 ± 0.30 ng/μg for Xushu 32)
• Tentatively identifies 128 resin glycosides based on UHPLC-Q-TOF-MS/MS analysis
• Identifies four specific pentasaccharide resin glycosides as potential marker compounds for inhibition

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is contained in a DOCX file (1.1 MB), which may require extraction of tabular data
