Tapiasin3Study Findings
• Antidiabetic: Study of C. procumbens on alloxan-induced diabetic rats showed the test drug to have good hypoglycemic effects. Results showed reduction of blood glucose, triglycerides and cholesterol levels.
• Anti-Inflammatory: Ethanolic extract of the aerial parts of C. procumbens exhibited significant anti-inflammatory activity with inhibition of carrageenan-induced rat paw edema and inhibition of leukocyte migration and reduction of pleural exudates in the cotton pellet granuloma method.
• Antibacterial: Study of aqueous extract showed antibacterial activity against B. subtilis, S. aureus, E. coli, P. aeruginosa, P. vulgaris and K. pneumonia in comparison with standard drug ciprofloxacin.
• Antibacterial / Leaves: Ethanolic extracts of leaf of C. procumbens showed significant antibacterial activity against S. aureus, Strep pyrogenes.
• CNS Depressant Effects / Analgesic: Alcoholic extract of whole plant produced central nervous system depression and significant prolongation of pentobarbitone sleeping time. The extract also exhibited significant analgesic effect.
• Antioxidant / Leaves: Study evaluated the in vitro antioxidant activity of ethanolic extract of C. procumbens by DPPH and Nitric oxide radical inhibition activity assays. Results showed promising results. Standards used were ascorbic acid and rutin.
• Anthelmintic / Leaves: Study evaluated various extracts of leaves for anthelmintic activity against earthworm Pheretima Posthuma. Ethanolic and aqueous extracts showed potent anthelmintic activity compared with Albendazole.
• Hepatoprotective / D-Galactosamine Induced Liver Injury: Study evaluated a chloroform extract of whole plant for hepatoprotective activity against D-Galactosamine induced liver injury in rats. Results showed significant reversal of biochemical changes.
• Antimicrobial / Leaves: Study evaluated ethanol extracts of Heliotropium indicum and Coldenia procumbens for antimicrobial activity against S. aureus, B. subtilis, Strep pyogenes, P. aeruginosa, K pneumonia, Aspergillus niger, T. viride and Candida albicans. Results showed the leaf extract to showed the highest activity against both bacteria and fungi. H. indicum leaf extract showed highest inhibitory activity.
