EFFECT OF CANNA INDICA L. EXTRACT AGAINST CAFFEINE-NICOTINE CO-ADMINISTRATION-INDUCED EXAGGERATION IN TYPE 2 DIABETIC RATS
Objective: This study was designed to evaluate the protective effect of Canna indica L. extract against caffeine-nicotine administration-induced type 2 diabetes exaggeration in rats.Methods: A study was conducted for three weeks in four rat groups (n=6); viz.ĂÂ type 2 diabetic control group, a caffeine-nicotine diabetic control group (20mg/kg, 0.4mg/kg, ip twice daily), ĂÂ and Canna indica L. extract and caffeine-nicotine treatment group and ĂÂ standard drug treated caffeine-nicotine diabetic group (Glibencamide, 5mg/kg, once daily). Type 2 diabetes was induced by two weeks high fatty diet and a single dose streptozotocin (50mg/kg, ip) on 1th day of the study in all groups. Blood and urine samples were collected every week for serum biochemical analysis.Results: Results of extract treatment and standard drug treatment were compared with untreated caffeine-nicotine co-administration group. Difference in each relevant serum parameter was analyzed through ANOVA and Dunett's t test. Extract treated caffeine-nicotine-diabetic group showed about 150-200mg/dL (p<0.001) reduction in the serum glucose than untreated caffeine-nicotine-diabetic control group. Extract treatment reduces serum glucose by 10-15 mg/dL than glibenclamide treatment with higher significance (p<0.001). Extract treatment showed better results than standard drug in liver and kidney function test and exhibited its better potential in controlling diabetic complications. Extract treatment increased HDL-C and reduced triglycerides, LDL-C, VLDL-C and TC much better and with higher significance than standard drug. Extract treatment reduced TC by at least 60-80mg/dL (p<0.01) in comparison to caffeine-nicotine-diabetic control group. Extract treatment reduced 10-15mg/dL of more total cholesterol than that of standard drug.Conclusion: Caffeine-nicotine co-administration-induced exaggeration of type 2 diabetes was better treated by CI extract than that of standard drug gibenclamide.ĂÂ Keywords: Type 2 diabetes, Streptozotocin, Caffeine, Nicotine, Diabetic complication, Ra
Antibacterial Effectiveness of Rice Water (Starch)âCapped Silver Nanoparticles Fabricated Rapidly in the Presence of Sunlight
Antioxidant, antibacterial and cytotoxic potential of silver nanoparticles synthesized using terpenes rich extract of Lantana camara L. leaves
Several attempts have been made for green synthesis of silver nanoparticles (AgNPs) using different plant extracts. Present study revealed that, antioxidant, antibacterial and cytotoxic AgNPs were synthesized using terpenes-rich extract (TRE) of environmentally notorious Lantana camara L. leaves. AgNPs were characterized by advanced techniques like UVâVisible and Infra red spectroscopy; XRD, SEM techniques as terpenes coated sphere shaped NPs with average diameter 425Â nm. Further, on evaluation, AgNPs were found to exhibit dose â dependent antioxidant potential, good to moderate antibacterial activity against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa; and toxicity on Brine shrimp (A. salinanauplii) with LD50 value 514.50Â Âľg/ml
Phytochemical analysis of Canna indica L. roots and rhizomes extract
Canna indica L. (Cannaceae) roots and rhizomes were reported to possess various biological properties like antimicrobial, anthelmintic potential and HIV-1 reverse transcriptase inhibition. In our previous studies, they showed antidiabetic activity on normal rats and rats co-addicted with caffeine and nicotine. In the pursuit of the phytochemical/s responsible for these biological activities, present study was aimed at phytochemical evaluation of hydroalcoholic extract (HAE) of C. indica L. roots and rhizomes; including preliminary screening, thin layer chromatography, H1-NMR and HR-LC/MS-MS analysis. After preliminary detection of flavonoids, tannins and sterols, HAE was tested for presence of β-sitosterol using TLC. H1-NMR spectrum of HAE revealed the presence of around 761 deshielded protons corresponding to different polar compounds. HR-LC/MS-MS analysis carried out at both positive and negative ion mode, indicated the presence of more than 90 compounds including short fragment of peptide. As per METLIN database, predicted major phytochemicals were 3â˛-hydroxytrimethoprim, 3,7-epoxycaryophyllan-6-one, swietenine, typhasterol, hexacosanedioic acid and 3β, 6Îą,7Îą-trihydroxy-5β-cholan-24-oic acid few of which, are biologically active.
