<![CDATA[The potential of Rhizophora mucronata mangrove fruits as antioxidants is noteworthy, with promising prospects as nutraceuticals, particularly in their role as immunomodulators for T lymphocyte cells. R. mucronata fruits have been utilized by household industries in Indonesia as a coffee-like drink (artificial coffee). This study aims to determine the ability of mangrove fruit artificial coffee R. mucronata to stimulate T lymphocyte cells and renal histopathology conditions in LPS-induced mice animal models. This study also characterizes proximate characteristics, antioxidant capacity, and Gas Chromatography-Mass Spectrometry (GC-MS) screening of mangrove fruit artificial coffee compounds. The stages of this research included the process of mangrove fruit artificial coffee; analysis of proximate and caffeine; compounds screening (GC-MS) and toxicity prediction (Pro-Tox II); antioxidant capacity (DPPH); T lymphocyte cell expression (flow cytometry); and renal histopathological evaluation. The results showed moisture content (5.22±0.20%); ash (5.17±0.27%); protein (13.74±0.24%); fat (11.63±0.32%); carbohydrate (64.23±0.15%), caffeine (1.09±0.04%). GC-MS analysis showed that the compounds contained in artificial coffee were derivatives of fatty aldehyde, fatty acid, and cycloalkanes compound classes. Predicted toxicity of artificial coffee LD50 5000 mg/kg. Antioxidant capacity is classified as moderate (IC50 119.41±0.99µg/mL). Mangrove fruit artificial coffee can increase the relative number of CD4+CD62L+ by 14.68-29.48% and CD8+CD62L+ T lymphocyte cells by 12.60-30.33%. Artificial coffee can also increase the number of healthy cells and reduce the cells that undergo necrosis in the renal of LPS-induced mice. This study concluded that mangrove fruit artificial coffee R. mucronata positively affects T lymphocyte activation and mice renal cells’ protection from necrosis due to LPS induction. ]]>
