Yiqi Yangxin Anshen Oral Liquid (YQYX) is a multi-herbs compound derived from the ancient Chinese formulae Suanzaoren Decoction and Guipi Tang. It has been clinically used to treat insomnia and anxiety for nearly three decades. To evaluate the efficacy of YQYX and to elucidate its therapeutic mechanisms in mitigating pathological changes induced by sleep deprivation (SD). Chemical constituents and serum-absorbed components were characterized using UHPLC-Orbitrap-MS/MS. Network pharmacology was employed to predicted therapeutic targets. PCPA-induced SD rats underwent pentobarbital-induced sleep test, Morris water maze, and open field test. Serum inflammatory cytokines were measured by ELISA, and hypothalamic neurotransmitters were quantified using a validated UHPLC-QQQ-MS/MS method. Hippocampal damage was evaluated by H&E and NeuN immunofluorescence, and cAMP/PKA/CREB/BDNF pathway was studied by Western blot and immunofluorescence. LC-MS identified 102 chemical constituents and 49 serum-absorbed components in YQYX. Network pharmacology analysis based on the serum-absorbed components predicted the cAMP signaling pathway as a key therapeutic target. YQYX significantly ameliorated SD-induced sleeplessness effects, spatial learning-memory impairments, and anxiety-like behaviors. It also reduced serum levels of IL-1β, TNF-α, and IL-6. Notably, YQYX restored hypothalamic neurotransmitters homeostasis (serotonin, dopamine, histamine, and acetylcholine). Histological analysis showed that YQYX prevented SD-induced hippocampal damage. Moreover, YQYX upregulated the cAMP/PKA/CREB/BDNF signaling pathway. YQYX exhibits multi-target therapeutic effects by maintaining neurotransmitter homeostasis, protecting hippocampal neurons, and activating neuroplasticity pathways, thereby validating its ethnopharmacological basis for treating sleep disorders.
