Background/Objectives: Hyperlipidemia is a serious risk factor for cardiovascular diseases and liver steatosis. In this work, we explored the effect of an herbal formula (CBF) containing immature Ceratonia siliqua pods and Ocimum basilicum extracts on lipid metabolism disorders and lipoprotein-rich plasma (LRP) oxidation in mice. Methods: The phenolic composition was determined using HPLC-DAD analysis. The antioxidant activity was studied using various in vitro methods. Acute toxicity was evaluated in mice. Importantly, the effect of the CBF on lipid metabolism disorders was investigated in a high-fat diet (HFD) hyperlipidemia mouse model. An in silico study was carried out to predict underlying mechanisms. Results: The HPLC analysis revealed gallic acid, cinnamic acid, and naringenin as major phenolics of the carob pod aqueous extract. Concerning the basil hydro-ethanolic extract, rosmarinic, chicoric, caftaric, and caffeic acids were the main phenolics. Accordingly, the CBF prevented LRP oxidation in a concentration-dependent manner. This formula is not toxic in mice (LD₅₀ > 2000 mg/kg body weight). Moreover, animals administered the CBF at 200 mg/kg/day presented a significant decline in their body weight gain, adipose tissue weight, plasma total cholesterol, low-density lipoprotein cholesterol (LDL-C) level, and glycaemia after 10 weeks’ treatment. Accordingly, the CBF decreased the plasma atherogenic index and the LDL-C to HDL-C ratio and reduced the level of fats accumulated in the liver. The molecular docking study revealed that chicoric, rosmarinic, and caftaric acids, and naringenin bound particularly strongly to many proteins involved in the regulation of lipid and cholesterol metabolism. This includes the HMG-CoA reductase, PPARα/γ, PCSK9, Cyp7a1, and ATP-citrate lyase. Conclusions: The CBF could be a good source of natural supplements, functional foods, and pharmaceuticals effective in managing hyperlipidemia and oxidative stress and preventing their related cardiovascular disorders.

Background: This study investigated the hypolipidemic and hepatoprotective effects of refined soybean oil supplemented with an Ocimum basilicum L. extract, characterized by HPLC and found to be rich in caftaric, caffeic, chicoric, and rosmarinic acids. Methods: After a 12-week model of diet-induced hyperlipidemia, we examined the plasma levels of TC, TG, Glucose, HDL-C, and LDL-C and the LDL-C/HDL-C ratio using enzymatic kits. The Plasma Hepatic and Biliary Marker Analysis was analysed following standardized hospital protocols with quality-controlled instrumentation. Results: The supplementation with Basil-Enriched Oil (BEO) resulted in a notable redistribution of lipids, significantly reducing the plasma total cholesterol (−75%), triglycerides (−96%), and glucose (−22%), while enhancing their hepatic sequestration. This was accompanied by a marked improvement in the LDL-C/HDL-C ratio and a reduction in hepatic oxidative stress (measured by MDA). Importantly, BEO preserved liver structure and prevented steatosis, despite inducing an increase in adaptive hepatomegaly. Conclusions: The results reveal a dual mechanism whereby the antioxidant properties of BEO collaborate with reprogrammed lipid metabolism, promoting safe hepatic storage rather than harmful circulating levels. These findings strongly advocate for the extract’s potential as a nutraceutical for addressing hyperlipidemia and related metabolic disorders by targeting both oxidative stress and lipid imbalance. Further research is required to confirm these effects in clinical settings and to confirm its long-term efficacy.

Species of the Opuntia genus are widely recognized for their richness in bioactive metabolites and antioxidant potential, particularly in their cladodes. However, despite increasing interest in cochineal-resistant cultivars, their genotoxic safety remains poorly explored. In this study, the phytochemical composition, antioxidant activity, and genotoxic effects of cladode extracts from three Dactylopius opuntiae-resistant Opuntia species (O. ficus-indica, O. robusta, and O. stricta) collected in eastern Morocco were comparatively evaluated. Hydroethanolic extracts were characterized for their biochemical composition and screened for antioxidant activity using DPPH, β-carotene bleaching, FRAP, and total antioxidant capacity assays. An untargeted UHPLC-Orbitrap MS/MS approach was applied to profile secondary metabolites, while genotoxicity was assessed using the comet assay on rat leukocyte DNA. The three species exhibited distinct phytochemical and antioxidant profiles. O. ficus-indica showed the highest total phenolic and flavonoid contents and the strongest radical scavenging and reducing capacities, whereas O. stricta was particularly rich in ascorbic acid and exhibited the highest total antioxidant capacity. Metabolomic analysis revealed a predominance of phenolic acids and flavonoids, with piscidic acid as a major constituent, along with isorhamnetin derivatives and organic acids. Importantly, none of the extracts induced genotoxic effects compared to the negative control, while all differed significantly from the oxidative damage induced by hydrogen peroxide. Overall, these findings demonstrate the phytochemical richness, antioxidant potential, and genotoxic safety of cochineal-resistant Opuntia cladodes, supporting their sustainable valorization in food, nutraceutical, cosmetic, and agricultural applications.
