Abstract:
Objective:To analyze and identify the non-medicinal parts in Zanthoxylum nitidum husk by HPLC-LTQ/Orbitrap-MS, and study the antioxidant activity, in order to provide the scientific basis for further research and development of Z. nitidum. Method:Data is collected by HPLC-LTQ/Orbitrap-MS,and high-resolution MS and MS2 spectra of mass spectrogram of chromatographic peaks were analyzed and compared with the literature database. The structure of each chromatographic peak was calculated and confirmed. The anti-oxidative activity of the Z. nitidum husk was studied by DPPH scavenging free radical ability and ABTS free radical scavenging ability. Result:Twenty-five alkaloids were identified from Z. nitidum husk. The main constituents were isoquinoline alkaloids (nitidine,liriodenine,magnocurarine),pyrrolidine alkaloid (allocryptopine,oxymatrine,oxysophocarpine),quinoline alkaloid (magnoflorine,nitidine chloride),and organic amine alkaloids (γ-sanshool). Antioxygenic activity was studied by DPPH scavenging free radical ability and ABTS free radical scavenging ability. The results showed that they were within the measured concentration range, the antioxidant activity increased with the rise of the sample concentration, a good dose dependence was presented. Conclusion:In this paper,the chemical constituents and the activity Z. nitidum husk were studied. Studies have shown a variety of alkaloids, with a good antioxidant activity. This study provides a reference for further research and development of Z. nitidum.
