Abstract This study aimed to investigate the antidiabetic and antihyperlipidemic activity of the active fraction of Asparagus gonoclados root tubers (AGAF) in streptozotocin-induced diabetic rats. After 45 days of treatment with the active fraction (AGAF) of Asparagus gonoclados at a dose of 50 mg/kg b.w.t., the levels of fasting blood glucose (FBG), hemoglobin, HbA1c, insulin, serum lipid profiles, and renal and hepatic function markers were measured in all experimental groups of rats. Treatment with AGAF remarkably normalized the FBG, insulin, and lipid profile levels. AGAF also normalized the hepatic and renal function markers in STZ-induced diabetic-treated rats. The findings from our current study confirm that AGAF successfully alleviates diabetes mellitus and its associated complications by improving insulin secretion and action with no apparent toxic effects on the liver or kidney.

Abstract In our previous study on Salsola kali, the ethyl acetate extract revealed an in vitro cytotoxic effect against the tumor cell lines (MCF-7, HepG2, and A549). Therefore, this study was conducted to identify phenolic and flavonoid components in this extract by LC-ESI-TOF/MS technique and explore the mechanism of the cytotoxic effect on the progression of the cell cycle and the induction of apoptosis by flow cytometry. Further, protein markers were evaluated as cytotoxicity mechanisms to confirm apoptosis initiation. LC-ESI-TOF/MS analysis identified eleven phenolics and forty-five flavonoid compounds from the ethyl acetate extract. Ethyl acetate extract induced G1 cell population arrest in HepG2 cells after 24 hours of exposure. The flow cytometry data confirmed that ethyl acetate primarily initiates cell death by starting early and late apoptotic manners. Induction of apoptosis by ethyl acetate extract was proved by a significant increase in cytochrome C, caspase 3, and Bax levels, while the level of antiapoptotic BCl2 was significantly decreased. Moreover, the Bax/BCl2 ratio was increased after treatment in a dose-dependent manner of ethyl acetate extract compared to that of the untreated group. These findings suggest that ethyl acetate extract may have a remarkable anticancer effect in HepG2 cells through cell cycle regulation and apoptosis. GRAPHICAL ABSTRACT

Abstract Aquaculture is the fast-growing industry and, consequently, fish waste management is becoming a rising concern. Fish scale trash contains collagen as a biomaterial which offers excellent properties such as biocompatibility, biodegradability, porosity, low toxicity, cell adhesion and water absorption capacity which makes it suitable for biomedical research in the form of scaffolds. But the scaffolds have the limitation of having less stability. To overcome this shortcoming, collagen scaffolds can either be modified by chemical or physical treatments such as crosslinking with suitable polymers and dehydrothermal treatment, respectively. In the present study, extraction of fish collagen from the scales of Cyprinus carpio was performed followed by crosslinking with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) & N-hydroxysuccinimide (NHS). Comparative characterization was done by techniques such as ATR-FTIR, FESEM and TGA to analyse the chemical composition, surface morphology and thermal degradation of fish collagen scaffold (CS) with EDC/NHS crosslinked collagen scaffold (EDC/NHS-CS). Crosslinked collagen scaffold’s antimicrobial activity was also determined with agar well diffusion assay by using S. aureus strain of bacteria and cytotoxicity on mouse fibroblast cells (NIH/3T3) by MTT assay. Moreover, the biomedical industry wants to shift to sustainable approaches and fish collagen-based scaffolds may prove to be a potential source in tissue engineering. And thus, also help in the management of fish waste. GRAPHICAL ABSTRACT

Abstract Acanthaceous plants have emerged as important therapeutic plants on a global scale, producing biologically active chemical compounds with larvicidal, antimicrobial, and cytotoxic properties. In traditional Thai medicine, the crude extracts of these plants, including Clinacanthus nutans, Justicia gendarussa, and Rhinacanthus nasutus, have been used to detoxify bug bites and some skin illnesses caused by fungus and viruses. This study argued for investigating acanthaceous plant extracts for alternate advantages such as anti-inflammation. The presence of anti-inflammatory components in extracts was examined using HPLC in order to evaluate their potential. Lupeol, a prospective anti-inflammatory triterpene found in medicinal plants, was employed as a chemical marker. The anti-inflammatory activities of extracts containing the active chemical were studied utilizing protein denaturation and inhibition of nitric oxide production in RAW 264.7 cells stimulated with LPS. Also, the extract of combined active plants was assessed. Lupeol was detected in the tested extracts in quantities ranging from 0.25 to 1.22% w/w. It was found in the highest concentration in the extract of Clinacanthus nutans and in the lowest concentration in the extract of Justicia gendarussa. All extracts of plants containing the active ingredient exhibited anti-inflammatory effects. Their IC50 values ranged between 0.87 and 29.28 mg/mL. The extract made from a combination of plants that contained lupeol demonstrated the most potent anti-inflammatory effect, with a 0.6-fold difference when compared to diclofenac. This research implied that investigating acanthaceous plant extracts containing this active agent might be more beneficial in the design of herbal recipes with anti-inflammatory characteristics.

Abstract The present study describes the isolation and structural elucidation of bioactive natural products from the hydro ethanol extract of Dilenia indica L. barks (DIHEEB) and their inhibitory activity against α-amylase and α-glucosidase enzymes. Some natural products including n-nonyl oleate (1), stigmasterol (2), β-sitotenone (3), betulin (4), and betulinic acid (5) were isolated from the DIHEEB extract. These natural products were characterized through IR, NMR, and mass spectroscopy. Among all these compounds, 4 and 5 have shown significant activity to inhibit α-glucosidase and α-amylase, which proves their anti-diabetic effect. The α-amylase and α-glucosidase inhibitory activity of 4 (α-amylase: IC50 68.79±1.6 μg/ml; α-glucosidase: IC50 69.19±1.8 μg/ml;) are very much comparable with known anti-diabetic drug acarbose (IC50 64.70±1.6 μg/ml). But compound 5 also shows a comparable extent of activity against α-amylase and α-glucosidase and it is also well established in the literature. Molecular docking and other in-silico properties were studied to elucidate the interactions and conformations of the isolated molecules with the target protein enzyme. With minimal conformational energy, 4 and 5 bind to the α-amylase (PDB ID: 4GQR) and α-glucosidase (PDB ID: 3A4A) enzymes, as proved by their respective docking score (-8.2 and -9.4 kcal/mol) and having different types of binding interactions. Also, the pharmacokinetics (PK), drug-likeness scores (DLS), and well permeability properties were studied along with no violation of Lipinski’s rule. Both in vitro and in silico results suggest that D. indica could be a potential source of anti-diabetic formulations. GRAPHICAL ABSTRACT

Abstract Three depsides, namely sekikaic acid (1), homosekikaic acid (2), and 4′-O-demethylsekikaic acid (3) were isolated from acetone fraction of Ramalina spp. The structures were characterized by using spectroscopic techniques like 1H NMR, 13C NMR, ESI MS and IR. The quantitative determinations of these compounds were conducted by reversed phase high performance liquid chromatography with photodiode array detector (LC-PDA). The developed assay method could be considered as a suitable quality control method for Ramalina spp. The content on percentage dry basis of these compounds were 1.39%, 0.98% and 0.58% for compound 1, 2 and 3, respectively. It is the first time report for tyrosinase inhibition activity for depsides. All of these compounds exhibited inhibition for tyrosinase enzyme with the IC50 values 110.3±3.5, 90.1±1.4, and 206.4±5.1 µg/mL by the compounds 1, 2 and 3, respectively. The structure activity relationship of despides showed that the methoxy group at ring A might have enhanced the inhibitory activity. Therefore, these compounds may have their potential use in cosmetics with further studies. GRAPHICAL ABSTRACT

Abstract The use of Moringa oleifera leaves as a poultry feed has been recognized worldwide, thanks to its multi-beneficial properties for broiler quality and production. However, research on the absorption and bioaccessibility of antioxidant compounds in this material is still limited. This study aims to investigate the effect of simulated poultry digestion on the bioaccessibility of quercetin 3-D-galactoside (Q3G) from Moringa leaf extracts and its antioxidant capacity via an in vitro model. Initially, a bio-guided fractionation procedure was employed to isolate Q3G and co-occurring antioxidants from Moringa leaves using column chromatography. The identification of Q3G and major phytocompounds within the potent active samples was carried out using high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/ MS). The findings revealed that Q3G is predominantly present in the ethyl acetate extract of Moringa leaves, with the highest concentration recorded as 1.3 mg/g of dry weight. Via a simulated poultry digestion model, the bioaccessibility of Q3G in the small intestinal stage was calculated to have the highest proportion of 67.1%. Significantly, the change in Q3G content was in accordance with the tendency for antioxidant activity of the Q3G-included fractions throughout the digestion. The correlation analysis suggested that Q3G has an important role in the antioxidant capacity of Moringa leaf extracts. To the best of our knowledge, this study represents a pioneering attempt to investigate the bioaccessibility and antioxidant activity of Q3G and Q3G-included extracts from Moringa leaves, utilizing an in vitro poultry digestion model.

However, research on the absorption and bioaccessibility of antioxidant compounds in this material is still limited. This study aims to investigate the effect of simulated poultry digestion on the bioaccessibility of quercetin 3-D-galactoside (Q3G) from Moringa leaf extracts and its antioxidant capacity via an in vitro model. Initially, a bio-guided fractionation procedure was employed to isolate Q3G and co-occurring antioxidants from Moringa leaves using column chromatography. The identification of Q3G and major phytocompounds within the potent active samples was carried out using high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/ MS). The findings revealed that Q3G is predominantly present in the ethyl acetate extract of Moringa leaves, with the highest concentration recorded as 1.3 mg/g of dry weight. Via a simulated poultry digestion model, the bioaccessibility of Q3G in the small intestinal stage was calculated to have the highest proportion of 67.1%. Significantly, the change in Q3G content was in accordance with the tendency for antioxidant activity of the Q3G-included fractions throughout the digestion. The correlation analysis suggested that Q3G has an important role in the antioxidant capacity of Moringa leaf extracts. To the best of our knowledge, this study represents a pioneering attempt to investigate the bioaccessibility and antioxidant activity of Q3G and Q3G-included extracts from Moringa leaves, utilizing an in vitro poultry digestion model. The findings establish a crucial foundation for future research and development endeavors that aim to produce antioxidant supplements enriched with Q3G from natural sources for applications in poultry production.

Abstract This study aimed to evaluate the antidiabetic and antioxidant potentials of fractions from Cassia siamea and Butea monosperma. The water, hexane, dichloromethane, and ethyl acetate fractions of tested plants was determined their bioactivities by hemolysis, antiglycation, alpha-glucosidase and dipeptidyl peptidase-IV (DPP-IV) inhibition, glucose uptake by yeast cells, DPPH radical scavenging, and total phenolic content determination assays. Non-hemolytic effects of all fractions were shown by < 20% on RBCs. The best inhibition activities for AGE formation of water and hexane fractions from C. siamea were shown in IC50 values (mg/mL) of 0.17 and 0.14, respectively. For B. monosperma, the EtOAc fraction exhibited the best inhibitory effect with an IC50 value of 0.10 mg/mL. The water and ethyl acetate fractions of C. siamea strongly inhibited α-glucosidase, and their IC50 values were 0.16 mg/mL and 0.17 mg/mL, respectively. Ethyl acetate fractions of B. monosperma significantly inhibited α-glucosidase, with a respective IC50 value of 0.14 mg/mL. DPP-IV inhibitory activities for water, hexane, and ethyl acetate fractions of C. siamea revealed with IC50 values of 0.11, 0.09, and 0.18 mg/mL, respectively and those of B. monosperma were 0.23, 0.13, and 0.24 mg/mL, respectively. The glucose uptake effect observed in the water and ethyl acetate fractions of B. monosperma was better than that observed in the fractions of C. siamea at tested glucose concentrations (5-25 mM). In addition, all tested fractions were very active in antioxidant capacity. This study indicated that the water fraction of C. siamea and ethyl acetate fraction of B. monosperma exhibited the best antidiabetic potential with high antioxidant power. GRAPHICAL ABSTRACT

Abstract Carob (Ceratonia siliqua L.) is an evergreen tree widely cultivated in the Mediterranean contour thanks to its nutritional and economic value. Carob fruit (pods) and leaf preparations are used in traditional medicine as gastro-protective, anti-diarrheal, analgesic, laxative, hypocholesterolemic and anti-diabetic agents. Recent studies indicated that carob pods contain a variety of nutritional elements, including high amounts of carbohydrates, proteins (in seeds), and an appreciable amount of dietary fiber but low-fat content. Phytochemicals present in all parts of the plant are phenolic acids, flavonoids, hydrolysable and condensed tannins and volatile compounds, together with the functional sugar D-pinitol found in pods. These compounds were associated with many in vitro and in vivo pharmacological activities, including antioxidant, gastroprotective, anti-inflammatory, hypoglycemic, hypolipidemic, cardioprotective, anti-proliferative and cytotoxic activities. Clinical trials demonstrated a beneficial effect of carob fiber on cholesterolemia and the in vivo toxicological studies reported the safety of carob pulp and seeds, besides the low toxicity of leaves. This study aims to review the recent knowledge about the ethnopharmacological uses, nutritional and bioactive compounds available in Ceratonia siliqua, besides pharmacological effects and toxicity of carob pulp (unripe and ripe), seeds and leaves.
