Bioactive metabolites from Spilanthes acmella Murr.
Spilanthes acmella Murr. (Compositae) has been used as a traditional medicine for toothache, rheumatism and fever. Its extracts had been shown to exhibit vasorelaxant and antioxidant activities. Herein, its antimicrobial, antioxidant and cytotoxic activities were evaluated. Agar dilution method assays against 27 strains of microorganisms were performed. Results showed that fractions from the ch...
متن کاملVasorelaxant and Antioxidant Activities of Spilanthes acmella Murr.
This study reports the effect of Spilanthes acmella Murr. extracts on phenylephrine-induced contraction of rat thoracic aorta as well as their antioxidant activity. Results show that the extracts exert maximal vasorelaxations in a dose-dependent manner, but their effects are less than acetylcholine-induced nitric oxide (NO) vasorelaxation. Significant reduction of vasorelaxations is observed in...
متن کاملIN VITRO FLOWERING OF SHOOTS REGENERATED FROM CULTURED NODAL EXPLANTS OF Spilanthes acmella MURR
An efficient protocol for in vitro flowering of Spilanthes acmella Murr., a medicinally valuable plant, has been developed. Multiple shoot formation of up to 4 shoots was obtained on Murashige and Skoog (MS) medium supplemented with BAP (1.0 mg/l). Regenerated shoots were subcultured cultured on MS medium containing various concentrations of BAP alone or in combination with IAA. Presence of BAP...
متن کاملEvaluation of nutrient uptake and physical parameters on cell biomass growth and production of spilanthol in suspension cultures of Spilanthes acmella Murr.
Spilanthes acmella Murr. has a plethora of highly valuable biologically active compounds and has been listed as one of the important medicinal plants of the world. However, no perceptible biotechnological advances have been made for this genus to exploit or enhance its utility. To nullify the effect of seasonal variations, the present report is the first attempt to establish in vitro cell suspe...
متن کاملIn Vitro Response of Encapsulated Shoot Tips of Spilanthes Acmella
Multiple shoots were achieved through axillary bud explant of Spilanthes acmella on MS medium supplemented with 0.5mg/l BA. In vitro developed axillary buds and tiny shoots isolated from the multiple shoots were encapsulated in different strength of sodium alginate. The present work explains the role of components of culture medium on morphogenic response of encapsulated shoot tips to various t...
