ABSTRACT
The changes in effective components of Juglans mandshurica at different harvest periods were analyzed by UPLC-Q-TOF-MS/MS. Eighteen batch samples of J. mandshurica from six harvest periods were assessed by multivariate statistical analysis with Markerview software. The formula of different compounds were determined by accurate mass and isotopic abundance ratio from target screening function of Peakview 2.0/Masterview1.0 software. Then their structure were determined by analysis of MS/MS fragment or comparison with standard substances and references. Naphthoquinone are the major markers in samples of Juglans mandshurica from different harvest periods. Thirty-eight of naphthalenequinones were identified or inferred in J. mandshurica and contents decline gradually. UPLC-Q-TOF-MS method which develops a new strategy can identify and analyze chemical constituents from J. mandshurica rapidly and accurately, main chemical constituents can be used for quality evaluation and efficacy material research. The dynamic changes in the metabolite accumulation of J. mandshurica the basic data for harvesting medicinal plants at different times.
