  Moringa oleifera has anti-inflammatory and antioxidant properties, but its effects in polymicrobial sepsis are incompletely defined. We evaluated M. oleifera oil (MOO) in female Wistar rats subjected to cecal ligation and puncture (CLP). Forty rats were randomized to Control, Sham, CLP, CLP + MOO 100 mg/kg, or CLP + MOO 200 mg/kg (n = 8/group). At 24 h, survival, clinical scores, serum apelin, omentin-1, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), malondialdehyde (MDA), recoverable bacterial burden, and histopathology were assessed. CLP decreased omentin-1 and increased IL-6, TNF-α, MDA, recoverable Staphylococcus aureus and Escherichia coli, clinical severity, and multi-organ injury. At 200 mg/kg, apelin and omentin-1 were 1.15 ± 0.12 and 28.4 ± 3.1 ng/mL, while IL-6, TNF-α, and MDA decreased to 18.4 ± 1.8 pg/mL, 24.1 ± 2.8 pg/mL, and 2.5 ± 0.3 nmol/mL, respectively. Neither organism was recovered above the detection limit. Survival was 62.5% in CLP, 87.5% with 100 mg/kg, and 100% with 200 mg/kg MOO. Within this 24 h model, a single post-CLP oral dose of MOO was associated with lower inflammatory cytokine concentrations and MDA, reduced recoverable bacterial burden, improved clinical and histopathological findings, and higher descriptive survival. Because MDA was the sole oxidative endpoint and no non-septic MOO-only group or molecular redox assays were included, these findings support the attenuation of sepsis-associated lipid peroxidation but do not establish a direct antioxidant mechanism.

  Bee products are an important source of nutrients and bioactive phytochemicals. This study aimed to determine the chemical composition (proximate composition, general phytochemical composition, sugar, and phenolic profiles) of four different products (honey, bee pollen, bee bread, and propolis), obtained from the same apiary, as well as to assess their biological activity through antioxidant and enzyme inhibition assays (α-amylase, α-glucosidase, lipase, AchE, neuraminidase, angiotensin-converting enzyme, urease, trypsin, tyrosinase, carbonic anhydrase, thioredoxin reductase, adenosine deaminase). Clear differences were observed among the samples in terms of both chemical composition and biological activity. The analysis revealed that bee pollen exhibited the highest carbohydrate content (87.9%), while propolis was identified as the richest source of phenolic compounds (14,858.9 mg/kg) among the analyzed samples. Propolis exhibited the highest biological activity in all applied antioxidant assays (CUPRAC, DPPH•, and ABTS•+) and in most enzyme inhibition assays. Notably, the α-glucosidase inhibition activity of propolis was comparable to that of the reference standard. In addition, honey exhibited remarkable trypsin inhibition, also comparable to the applied standard. These findings highlight the diverse bioactivities of hive products, which could play a key role in promoting health and preventing diseases.
