Analysis of components absorbed into blood and brain of Lithocarpus litseifolius leaves
To analyze the prototype components absorbed into blood and brain of
Lithocarpus litseifolius
leaves, so as to provide a reference for clarifying the pharmacological material basis of its prevention and treatment of central nervous system dis
eases.
METHODS
2
The ethanol extract of
L. litseifolius
leaves, as well as the gastric lavage fluid and perfusion solution were prepared. Using rats as subjects, plasma samples of intestinal wall metabolism, intestinal flora metabolism and hepatic metabolism were prepared via
in situ
intestinal perfusion and closed intestinal loop method; while comprehensive metabolic plasma samples, brain tissue samples, and cerebrospinal fluid samples were collected after intragastric administration. UPLC-HRMS technology was utilized to analyze and identify chemical components and prototype components absorbed into blood and brain of
L. litseifolius
leaves.
RESULTS
2
A total of 66 chemical constituents were identified in
L. litseifolius
leaves, primarily consisting of flavonoids, organic acids, and others. A total of 16, 13, 11, and 5 prototype components were identified in intestinal wall metabolism, intestinal flora metabolism, hepatic metabolism, and comprehensive metabolic plasma samples, respectively. Additionally, 4 prototype components were detected in brain tissue and 9 in cerebrospinal fluid. Phloridzin, trilobatin, phloretin-2-
O
-malonyl hexoside, and phloretin were identified as common components across all sample types.
CONCLUSIONS
2
Prototype components absorbed into blood and brain of
L. litseifolius
leaves,
such as phloridzin, trilobatin, phloretin, and other components may serve as the pharmacological material basis for their therapeutic effects on central nervous system diseases.
