2?-hydroxybetulinic acid 3?-caprylate: an active principle from Euryale Ferox Salisb. seeds with antidiabetic, antioxidant, pancreas & hepatoprotective potential in streptozotocin induced diabetic rats.

ABSTRACT: The aim of the present study was to evaluate the glycemic control, antioxidant, pancreas and liver protective effect of 2?-hydroxybetulinic acid 3?-caprylate (HBAC) from Euryale ferox Salisb. seeds on streptozotocin induced diabetic rats. The active principle was isolated from Euryale ferox Salisb. seeds extract by utilizing chromatographic techniques. The rats were divided into seven experimental groups: Gp 1-normal; Gp2- normal?+?HBAC (60 mg/kg p.o.); Gp3- diabetic control; Gp 4- Diabetic?+?HBAC (20 mg/kg p.o.); Gp5- Diabetic?+?HBAC (40 mg/kg p.o.); Gp6- Diabetic?+?HBAC (60 mg/kg p.o.) and Gp 7- Diabetic?+?Glibenclamide (10 mg/kg p.o.). Biochemical estimation, free radical scavenging examination and histopathological study was performed at the end of experimentation i.e. on 28th day. The active principle isolated and identified with spectral data as 2?-hydroxybetulinic acid 3?-caprylate (HBAC). It was detected for the first time that HBAC has improvised the glycemic control in streptozotocin induced diabetic rats. Furthermore, it is remarkable to note that it exhibited excellent free radical scavenging property and pancreas and hepatoprotective property as well, supported by histopathological examination. One of the mechanisms of action of HBAC appears to be stimulating the release of insulin from pancreatic ?-cells. HBAC improved the glycemic control, reduced the free radical activity along with corrected glycemic control, lipid profile, and enhanced level of insulin alongh with improvement in pancreas and hepatoprotective architecture. Considering the above results, HBAC shows potential to develop a medicine for diabetes as combinatorial or mono-therapy.

The aim of the present study was to evaluate the glycemic control, antioxidant, pancreas and liver protective effect of 2β-hydroxybetulinic acid 3β-caprylate (HBAC) from Euryale ferox Salisb. seeds on streptozotocin induced diabetic rats. The active principle was isolated from Euryale ferox Salisb. seeds extract by utilizing chromatographic techniques. The rats were divided into seven experimental groups: Gp 1-normal; Gp2- normal + HBAC (60 mg/kg p.o.); Gp3- diabetic control; Gp 4- Diabetic + HB ...[more]

Project description:Bio-fabrication of green or plant extract-based silver nanoparticles has garnered much praise over the past decade as the methodology is environment-friendly, undemanding, non-pathogenic, and economical. In the current study, leaves of Eurale ferox (Makhana), considered as waste, were used for the bio-fabrication of silver nanoparticles (ELAgNPs). Various analytical techniques including UV-VIS spectroscopy, Field emission scanning electron microscopy equipped with an energy dispersive X-ray spectrometer (FESEM-EDX), Particle size analyzer (PSA), Fourier transform infra-red spectroscopy (FTIR) and high-resolution transmission electron microscopy (HRTEM) were used for their characterization. Their antibacterial efficacy was examined against gram positive bacterium, Bacillus subtilis and gram negative bacterium, Escherichia coli. The antioxidant potential of the ELAgNPs was compassed by 2, 2 diphenyl-1-picryl hydrazyl (DPPH; λmax = 517 nm) assay, H2O2 (λmax = 230 nm) and OH- (λmax = 520 nm)-based radical scavenging assays. The cytotoxicity was checked against the VERO cell line using 3-[4, 5-dimethyl thiazol-2-yl]-2, 5 diphenyl tetrazolium bromide (MTT) assay. A mean particle size of 26.51 ± 8.87 nm with a size distribution of 7.08-53.94 nm was obtained using HRTEM. The ELAgNPs exhibited dose-dependent antibacterial efficacy with a maximum zone of inhibition (ZOI) of 21.98 ± 0.59 mm against B. subtilis and of 16.46 ± 0.22 mm against E. coli at 500 ppm after 24 h of incubation. The median lethal concentration for the cytotoxicity analysis was found to be 9.54 ± 0.35 ppm, 120.9 ± 6.31 ppm, and 20.74 ± 0.63 ppm for ELAgNPs, commercial silver nanoparticles (CAgNPs), and silver nitrate (SN), respectively. The ordinary one-way ANOVA results exhibited a significant decrease in cell viability after 72 h of incubation at p < 0.05, α = 0.05. In conclusion, the ELAgNPs showed good antibacterial, radical scavenging and dose-dependent cytotoxicity against the VERO cells. Therefore, these could be used for biomedical applications. Phyto-constituents present in the plant not only act as reducing agents but also as stabilizing and coating agents, and the availability of a wide range of metabolites makes the green approach more promising.
