BackgroundSolanesol is an important pharmaceutical intermediate raw material, mainly used to synthesize coenzyme Q10, vitamin K2. It can be found prominent in potato stems and leaves. But now potato stems and leaves are always abandoned or discarded as they are not suitable for use as feed in aquaculture or other purposes. These agricultural waste resources can be reutilized as the corresponding extracts.ObjectiveTo develop a simple and standardized method for the detection of total solanesol in potato leaves and its extracts.MethodsN-hexane was chosen as the extraction solvent for three times in the solanesol extraction from potato leaves. HPLC-MS was used for the detection.ResultsThe LOQ was 0.3 µg/g and the linear range was from 0.1 to 50 µg/mL. The precision and stability were evaluated by the relative standard deviations (RSDs) of three samples (potato leaves, Extract-1, Extract-2) for interday and intraday. The accuracy of the method was evaluated by the recoveries of three different spiked concentrations of solanesol for three samples, and results showed it ranged from 80.7% to 99.0% with RSDs less than 8.7%.ConclusionsThe method we established can provide a simple and standardized way for the extraction and detection of total solanesol.HighlightsThe work laid a foundation for the resource reutilization of potato stem and leaf.

S olanesol is a tetra sesquiterpene enol with various biological activities . Modern medical studies have confirmed that solanesol has the function of lipid antioxidation and scavenges free radicals. This study aimed to investigate the protective effect of solanesol against oxidative damage induced by high glucose on human normal hepatocytes (L-02 cells) and its possible mechanism. The results showed that solanesol could effectively improve the decrease of cell viability induced by high glucose, decrease the contents of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) in the extracellular medium, increased the enzyme activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT), balanced the level of reactive oxygen species (ROS) in cells, inhibited lipid peroxidation of all kinds of biological membranes, and restored mitochondrial membrane potential (MMP). In addition, Solanesol also inhibited the expression of Keap1, promoted the nuclear translocation of Nrf2 by hydrogen bonding with Nrf2, and activated the expression of downstream antioxidant factors NQO1 and HO-1. Altogether, these findings suggest that solanesol may be a potential protectant against diabetic liver injury.

Plant-derived terpenoids are essential secondary metabolites exhibiting broad-spectrum antibacterial properties. However, the bioactivities of terpenoids against Ralstonia solanacearum remain unexplored. Herein, the bioactivities of 30 terpenoids against R. solanacearum were assessed, and trans-anethole (TAN) was identified as a potent antibacterial agent with a minimum inhibitory concentration and minimum bactericidal concentration of 50 and 75 mg/L, respectively. TAN was low-toxic to silkworms, earthworms, seeds, and E. coli. Furthermore, TAN (>25 mg/L) significantly impeded the R. solanacearum growth, blocked ATP and exopolysaccharide (EPS) synthesis, caused DNA damage and cell rupture, and affected swimming motility and biofilm formation, and suppressed expressions of related genes. Compared with thiodiazole copper, and ethylicin, 100 mg/L TAN had a significantly greater control efficiency in both greenhouse and field tests. Importantly, TAN enhanced the abundance of the beneficial bacteria Bacillus and Sphingomonas. These findings highlight TAN as a potential bacterial wilt control agent.

Background: Parkinson’s disease (PD) is characterized by a complex interplay of dopaminergic degeneration, glial activation, and lipid metabolic dysregulation. However, accurately describing how natural product interventions remodel these pathologies across distinct brain regions and cellular microenvironments remains a critical challenge.Methods: We established an integrated multi-omics framework to decode the neuroprotective mechanisms of solanesol (Sol) in an MPTP-induced PD mouse model. We combined single-cell eQTL-based Mendelian randomization (scMR), transcriptomic localization, and virtual knockout analyses to prioritize cell-type-specific regulatory nodes across neuronal, glial, and vascular populations, avoiding the limitations of traditional bulk targeting. In vivo behavioral assays were conducted, alongside orthogonal validation via airflow-assisted desorption electrospray ionization mass spectrometry imaging (AFADESI-MSI) and gene–metabolite co-enrichment analysis, to map regional metabolic networks and structural spatial reprogramming.Results: Computational prioritization highlighted cell-type-specific regulatory nodes including PRKCB, PRKCE, PDGFRB, and FABP3/5. In vivo, Sol attenuated motor and cognitive deficits and largely restored the highly compartmentalized spatial distributions of striatal dopamine, L-DOPA, and acetylcholine. Crucially, AFADESI-MSI and co-enrichment analysis revealed that Sol specifically reversed MPTP-induced spatial disruptions by rescuing key neuromodulatory metabolites—including cervonoyl ethanolamide, phosphatidylcholine species, taurine, and NADHX—which were tightly coupled to sphingolipid signaling, fatty-acid transport, mitochondrial translation, and cell-adhesion pathways. Conclusions: Sol ameliorates PD-like pathology not through a singular target, but by choreographing a spatially and cellularly compartmentalized restoration of lipid–inflammatory homeostasis. Furthermore, our integrated single-cell and spatial metabolomic blueprint sets a new methodological paradigm for elucidating the precise execution programs of natural neurotherapeutics.

Carrier materials always account for the majority particularly in nanosized formulations, which are administrated along with the active ingredient part might result in metabolism related toxicity. The usage of bioactive excipients could not only reduce the sided effect but also provide additional therapeutic effects. In the present study, a triterpene based micellar drug delivery system was developed using a bioactive solanesol derivative. Solanesylamine was prepared firstly followed by conjugating with poly (ethylene glycol) using maleic acid amide linkage. The amphiphilic drug carrier PEGylated (2-propyl-3-methylmaleic acid)-block-solanesol amine (mPEG-CDM-NH-SOL) could be formed into micelles and loaded with doxorubicin (DOX) inside. The micelles were about 112 nm in size and the drug loading content was about 5.97 wt%. An acid triggered drug release behavior was obviously observed for the DOX loaded pH-sensitive micelle mPEG-CDM-NH-SOL-DOX. While not for DOX-loaded micelles without pH-sensitivity (mPEG-NHS-NH-SOL). CCK8 assay showed that the micelles of PEGylated solanesylamines exhibited certain inhibitory effect on tumor cells at high concentration and the pH sensitive ones seemed more toxic. In vivo studies showed that the pH sensitive mPEG-CDM-NH-SOL-DOX had a superior anti-tumor effect, indicating its great potential in cancer treatment.
