Herbal medicines possess a great demand in both developed and developing countries as a source of primary health care owing to their attributes having wide biological and medicinal activities, high safety margins and lesser costs. People living in rural areas of Nepal depend largely in the herbal medicines for the treatment. The present study concerns with the study of pharmacognostic characteristics, phytochemical constituents and the biological activity of Amaranthus spinosus L. The hexane, chloroform, ethanolic and aqueous extract of its aerial parts were subjected to preliminary phytochemical analysis and detected saponin, carbohydrate, tannin, protein, glycoside, flavonoid and phenol as phytoconstituents. The transverse section of the stem and leaves showed characteristic vascular bundle tissues. All the extracts were used for testing the antimicrobial activity and brine shrimp lethality. No extract showed the antimicrobial activity and ethanolic extract showed LC50 value of 31.62 ppm. Hexane, chloroform and water extracts were less toxic with LC50 values 236.88 ppm,194.98 ppm and 320.71 ppm respectively.DOI: http://dx.doi.org/10.3126/jmmihs.v1i4.11999Journal of Manmohan Memorial Institute of Health Sciences Vol. 1, Issue 4, 2015Page: 29-34

Present study aims to investigate phytochemical analysis as well as in vitro antimicrobial activity of crude aqueous, methanol, ethanol, chloroform and petroleum ether extracts from leaves of C. roseus. Antimicrobial activity of extract was studied against various bacterial strains (Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus and Mycobacterium smegmatis). Qualitative preliminary phytochemical analysis revealed that alkaloids, phenols, flavonoids, amino acid and cardiac glycosides are present in the extracts. The result for total phenol and flavonoids content was the highest in methanol and the lowest in petroleum ether crude extract. The study revealed that inhibition significantly depend upon the solvent used for extraction and bacterial strain tested for susceptibility. Aqueous extracts were found less efficient as compared to organic solvent. Methanolic extract were found more effective against tested microbes.

Tecoma stans is a flowering plant belonging to the family Bignoniaceae. It is the floral emblem of the Bahamas. Abutilon indicum belongs to the family Malvaceae. It is also called Indian Mallow. Tecoma stans and Abutilon indicumhave antimicrobial activity and can be used in producing antibiotics. There is an urgent need to produce new antibiotics as there is an increase in the development of pathogen resistant drugs. The aim of this study was to compare the antimicrobial activity of ethanolic extract of Tecoma stansand Abutilonindicum leaves. E.faecalis bacteria were maintained in nutrient agar slopes. The powder of the two herbs, were subjected to extraction by Soxhlet extractor and was concentrated to dry residue by Agar well diffusion method. The nutrient broth was inoculated with bacterial strains. The culture was adjusted to 0.5McFarland turbidity standard. Lawn culture was done in Muller-Hinton agar plate and then the plates were dried. A 6 mm diameter well is bored for different concentrations. The extracts were introduced into the well and allowed to stand for 24 hrs. The antibacterial activity was determined by measuring the zone of inhibition. The present finding on the antimicrobial potential of Abutilon indicum and Tecoma stands showed that the two plants have growth inhibitory activity against oral pathogen E. faecalis. Abutilon indicum has a zone of inhibition greater than Tecoma stans. Abutilon indicum exhibited better activity compared to Tecoma stans.
