Abstract
In this study, the components of Moringa oleifera (Lam) seed were extracted using an ultrasonic-assisted extraction technique with 70% methanol solution as the solvent. The antioxidant properties of the extract were evaluated through its scavenging abilities against DPPH. and ABTS. The antiproliferative effects of this extract on breast cancer MDA-MB-231, colon cancer SW480, leukemia HL-60, liver cancer SMMC-7721, and lung cancer A549 were assessed using the MTS assay. The distribution of MA, D-trehalose, and rbGlu in the heart, kidney, liver, and spleen of mice in various intervals was visually investigated using MALDI-IMS. In particular, the metabolic pathways of rbGlu were further elucidated. The result shows that rbGlu is metabolized to rbot-Glu in mice within 1 h. This approach further substantiates the use of MALDI-MSI technique in situ for studying the pharmacological mechanisms of bioactive component in natural products.
期刊介绍：
The Journal of Mass Spectrometry publishes papers on a broad range of topics of interest to scientists working in both fundamental and applied areas involving the study of gaseous ions.
The aim of JMS is to serve the scientific community with information provided and arranged to help senior investigators to better stay abreast of new discoveries and studies in their own field, to make them aware of events and developments in associated fields, and to provide students and newcomers the basic tools with which to learn fundamental and applied aspects of mass spectrometry.
