AbstractSince cyberloafing has become prevalent across organizations, scholars have increasingly focused on exploring its antecedents. Based on ego depletion theory, we explore how and when interest incongruence, a particular type of person‐environment misfit, influences employee cyberloafing behaviours. Using three‐wave survey data of a sample from 443 Chinese employees, we found that interest incongruence is associated with ego depletion, leading to employee cyberloafing. Furthermore, our results demonstrated the moderating roles of trait self‐control and moral identity internalization in the interest incongruence‐ego depletion‐cyberloafing link at different stages. Specifically, trait self‐control mitigated the effect of interest incongruence on ego depletion and the indirect effect of interest incongruence on cyberloafing via ego depletion. Moral identity internalization mitigated the effect of ego depletion on cyberloafing and the indirect effect of interest incongruence on cyberloafing via ego depletion. These findings suggest that employee cyberloafing is not only an immoral issue but also a behaviour affected by employees' self‐regulatory resources.

Therefore, it is necessary to seek more efficient hypoglycemic drugs. The main objective of this study was to investigate the potential hypoglycemic effects of compounds from Polygonum capitatum.Materials and Methods: Our experiments were divided into three steps: (1) α-amylase test and oral starch tolerance test (OSTT) for screening the biological extract part of P. capitatum; (2) chemical isolation and identification using various separation techniques, and spectrum methods; and (3) evaluation of α-amylase inhibitory activity of isolates and in silico analysis for mechanism investigation.Results: The n-butanol fractioned part of P. capitatum was confirmed to be the biological part according to α-amylase test. Then, two new triterpenoid saponins were isolated from the n-butanol part, which were also the first isolated triterpenoid saponins from P. capitatum. The activities of compounds 1 and 2 against α-amylase were 51.9± 2.8% and 38.1± 2.2%, respectively, which was consistent with the molecular docking analysis. In which, 1 and 2 showed the binding affinity energy for α-amylase was − 9.4 kcal/mol and − 7.8 kcal/mol, respectively.Conclusion: Two new triterpenoid saponins were firstly isolated from P. capitatum, and displays potency as a hypoglycemic agent through blocking α-amylase.Keywords: α-amylase, Polygonum capitatum, triterpene saponins, hypoglycemic
