In the search for new anti-Alzheimer’s and neuroprotective drugs from Polygonacae, P. hydropiper L. was identified, collected and processed for fractionation as previously reported from our laboratory (Ayaz et al., 2014b (link), 2016 (link)). A plant specimen was deposited with voucher no H.UOM.BG.107 at the herbarium of the University of Malakand, Chakdara, Dir (L), KP, Pakistan. Solvent based fractions and saponins were initially subjected to in vitro anti-Alzheimer’s studies. The solvent fractions, especially chloroform and ethyl acetate were selected for the isolation of pure compounds due to their prominent activities in preliminary assays. Several compounds were isolated using gravity column chromatography eluting with n-haxane and ethyl acetate. The purified compounds were rotary evaporated to remove any remaining solvent. Initially, 1H NMR spectra was obtained to reveal the chemical structure by comparing the spectra with those reported in the literature. The 13C NMR spectra were used to ascertain the carbon skeleton of the compounds. The spectral data was supplemented by using mass spectrometry to confirm the structures. Among the isolated compounds, β-sitosterol was most active in the preliminary analysis and was evaluated in detail (Figure 1).

The optimized chromatographic analysis was carried out using a Waters Alliance 2695 liquid chromatography system (Waters, Milford, CT, USA) equipped with 2996 photodiode array detector (Waters, Milford, CT, USA) and ACE C18 (150 × 4.6 mm, 3 μm) column (ACT, Aberdeen, UK). Since all triterpenoids cannot be separated in a single chromatographic run, different chromatographic conditions were used.
For the analysis of triterpenoid acids (maslinic, corosolic, betulinic, oleanolic, ursolic acids) and neutral triterpenoids with chromophores (betulin, erythrodiol, uvaol), the mobile phase consisted of acetonitrile and water (89:11, v/v), delivered at a flow rate of 0.7 mL/min in the isocratic mode. The column temperature was set at 20 °C with an injection volume of 10 μL. Whereas the isocratic elution system for the analysis of neutral triterpenoids, which lacks chromophores (lupeol, β-amyrin, α-amyrin, friedelin) and phytosterol (β-sitosterol), consisted of acetonitrile and methanol (10:90, v/v). The column temperature was set at 35 °C, the flow rate was 1 mL/min, and the sample injection volume was 10 μL.
Detection of all triterpenoids was performed at a wavelength of 205 nm corresponding to the maximum absorption, and peaks were identified with retention times as compared with standards.

In this analysis, 10 mg of b-sitosterol standard was dissolved in a few drops of PA-grade chloroform and then supplemented with HPLC-grade methanol to reach a final volume of 10 mL. This solution was then prepared as a stock solution at a concentration of 1000 ppm, and further dilutions were made as needed using HPLCgrade methanol until the desired concentrations were achieved. All solutions with varying concentrations were filtered through a 0.22 µm PTFE filter before being injected into the HPLC system. HPLC analysis was performed at a flow rate of 1 mL/minute, using a mobile phase composed of methanol:acetonitrile (9:1, v/v), C18 stationary phase, and a wavelength of 202 nm to detect b-sitosterol (Khonsa et al., 2022) (link). After obtaining the peak areas from the HPLC analysis, a graph was constructed by plotting the concentrations of the standard b-sitosterol solutions (x-axis) against the corresponding peak areas (y-axis). The resulting line equation became the standard curve for b-sitosterol.
For the analysis of b-sitosterol content in the dry extract of Javanese ginseng roots, the extract was initially dissolved in 5 mL HPLC-grade methanol. Subsequently, the extract solution was filtered through a 0.22 µm PTFE filter into an HPLC vial, reaching a final volume of 1.5 mL. This solution was then injected into the HPLC instrument using the same HPLC settings as those used for the analysis of standard b-sitosterol solutions of various concentrations. The peak area obtained from HPLC analysis was used as the y-value in the standard curve equation to determine the concentration of bsitosterol in the sample as the x-value.
The concentration of b-sitosterol was then converted into the b-sitosterol content in the root extract using Eq. ( 5) (Fuentes-Arderiu, 2013). where C(SIT) represents the concentration of b-sitosterol, Vs is the solvent volume (HPLC-grade methanol), and RPW is the weight of root powder used for one-sample replication. Furthermore, the bsitosterol productivity of the roots was calculated using Eq. ( 6) (Mangoli, 2020) . In calculating the b-sitosterol productivity from the roots, we assumed the dimensions of the hydroponic gully to be 2.1 m x 0.58 m (length x width) with a total of 48 plants in each hydroponic set.

A molecular docking approach was used to study the relationship between β-sitosterol and its main targets. Protein Data Bank (PDB; http://www.rcsb.org/pdb/home/home.do) was used to collect structural data of the key core genes and PubChem (https://pubchem.ncbi.nlm.nih.gov) was used to obtain chemical data of β-sitosterol. To simulate how β-sitosterol binds to the target protein, PyMol software was applied to dehydrate, hydrogenate, and charge. AutoDockTools-1.5.6 software was used to determine the location and size of the Grid box, the binding site of the disease target protein to the ligand. Autodock vina V1.1.2 software was used to complete the molecular docking and assess the affinity of the compounds to the target proteins. PyMOL software was used for visualization and numerical heat map analysis.

β-sitosterol was chosen as a marker for the determination of Pet-B as it is isolated in considerable amount from Pet-B together with its various biological activities viz. wound healing, anti-oxidant, anti-inflammatory or anti-microbial activities. It was determined by HPTLC (CAMAG) in Pet-B according to Mallick and Dighe (2014) [41 (link)].

Formulation of larval zebrafish HFD: Following the dissolution of 10 g of egg yolk powder and 1 g of cholesterol, the resulting mixture was homogenized on a magnetic stirrer and subsequently dried overnight in a freeze dryer (SCIENTE, Ningbo, China).
Formulation of adult zebrafish HFD: After the dissolution of 10 g of egg yolk powder, 10 g of cholesterol, and 3 g of glucose, the resulting mixture was homogenized with 100 g of zebrafish feed using a magnetic stirrer. Subsequently, the mixture was dried overnight in a freeze-dryer (SCIENTE, Ningbo, China). The HFD for the experimental group was enriched with 50 mg of β-sitosterol, while the control group received an equivalent amount of DMSO as the β-sitosterol group.
Construction of a larval zebrafish model of NAFLD: Fish were raised to 5 days post-fertilization (dpf) in an E3 medium, with 0.003% 1-phenyl-2-thiourea (PTU) added at 22 h post-fertilization (hpf) to clear pigment [33 (link)]. Zebrafish at 5 dpf were selected for the experiment, and the larvae were fed with HFD twice a day for 5 days. During feeding, 3% glucose solution was added for soaking, and the feeding time was 1 h. After feeding, a fresh E3 culture medium was replaced. The experimental group was given 200 μg/mL of β-sitosterol, the positive control group received 62.5 μg/mL of bezafibrate (a peroxisome proliferator-activated receptor activator that reduces blood lipids), and the control group received the same amount of DMSO as the β-sitosterol group. Subsequently, the accumulation of triglyceride and cholesterol in zebrafish larvae was detected [29 (link)]. Toxicity tests were used to determine bezafibrate and β-sitosterol concentrations.
Construction of an adult zebrafish model of NAFLD: This model was established by a feeding regimen of HFD administered twice daily for one month. Subsequently, the liver of the zebrafish was collected to determine the levels of cholesterol and triglyceride, followed by statistical analysis to confirm the establishment of the model [34 (link)].

The research design in this study used a completely randomized design (CRD) with four variations of chitosan concentrations: 0, 12.5, 25, and 50 ppm, along with 12 replications (for cultivation data) or 3 replications (for HPLC data). ANOVA (Analysis of Variance) One-Way test was conducted to determine the presence of differences among the data groups. If differences were found, ANOVA was followed by Tukey's test (at a significance level of 0.05) to assess the significance of the effects of chitosan concentration on variables such as root weight increase, shoot weight increase, growth rate, root-to-shoot ratio, b-sitosterol content in the roots, and b-sitosterol productivity from the roots. All statistical analyses in this research were conducted using Minitab 19 software.
