The supplied index reports: This study compared three water-based extraction methods for Metapanax delavayi leaves using UPLC-QTOF-MS/MS and GNPS molecular networking for compound identification and annotation. Under the tested conditions, subcritical water extraction performed favourably in yield, compositional diversity and antioxidant activity.

A total of 136 compounds were identified or annotatedAnalysis of aqueous extracts from Metapanax delavayi leaves by UPLC-QTOF-MS/MS and GNPS molecular networking; 12 key constituents were further confirmed against reference standards
