Curcuma amada and Curcuma aeruginosa are economically and medicinally very important species in India. Both of the species look similar in morphological nature. In the present study, an effort has been made to work out the identifying characters and detailed comparative account of both species for ready identification of the entire plant, live or in the herbarium and also the discrimination of drugs made from the rhizome of both species. The studies of both species revealed the presence of entire major compounds like alkaloids, flavonoids, glycosides, phenols, and tannins, saponins etc. The macroscopic and microscopic studies of both species expressed difference. The activities of the powder with different chemicals and fluorescent studies showed characteristic...

In this study, the phytochemical analysis took place for solvent extracts (petroleum ether, chloroform) and essential oils. Maceration method and hydrodistillation were used for the solvent extraction and essential oil extraction respectively. Solvent extract was studied for phytochemical analysis and antibacterial activities. The antibacterial activity of a solvent extract of Lantana camara L. leaf was investigated against Pseudomonas aeruginosa (gram -), E. coli (gram-) and Staphylococcus aureus (gram+). The paper disk agar diffusion methods tested the antibacterial activity inhibition of growth. Phytochemical analysis showed that solvent extract (petroleum ether, chloroform) contains more constituents than the essential oil of Lantana camara L. leaf. This difference might come from the volatile constituents and non-volatile constituents of this plant. Solvent extracts gave a positive test for most phytochemical analysis, but the oil gave a positive test only for carbohydrate and terpenoids. Staphylococcus aureus was highly susceptible to the petroleum extract than chloroform extract; with a zone of inhibition from 14.17 ± 0.29 mm to17.7 ± 0.2 mm. Pseudomonas aeruginosa was less susceptible...

A phytotherapeutic approach to modern drug development can provide many invaluable drugs from traditional medicinal plants. Medicinal plants have been considered as an important therapeutic aid for alleviating ailment of humankind. Numerous plants and polyherbal formulations are used for the treatment of liver diseases. This present investigation was aimed at assessing the hepatoprotective activity of aqueous, ethanol and acetone extract of Sesbania grandiflora leaves against carbon tetrachloride (CCl4) induced liver damage in Albino rats. Silymarin as a standard drug for comparing the activity. The activity was assessed by comparing the biochemical parameters in serum levels such as serum glutamate pyruvate transaminase, serum glutamate oxalate transaminase, total bilirubin, alkaline phosphatase of plant extracts treated group with carbon tetrachloride treated animals. Results showed, ethanolic extract treated group showed highly significant activity (P<0.001), whereas aqueous extract treated group has shown the significant (P<0.01) action but less compared with ethanolic extract, acetone treated group showed moderate action. Plant extracts restore biochemical enzymes and bring down to normal as compared to standard drug silymarin....

Emergence of multidrug-resistant strains of pathogens and adverse effects of antibiotics have rapid lead search for new antimicrobials. Medicinal plants have gained more importance as a source of alternative and effective drugs. Euclea racemosa sub sp. schimperi (DC.) Dandy (Ebenaceae) has many traditional uses against infections and related disorders. The objective of this study was to evaluate the antibacterial potential and identify major phytochemical groups in root extracts of E. racemosa. Root part of the plant was extracted by maceration using methanol, acetone, and chloroform. Extracts were subjected to antibacterial screening against seven bacteria strains: Staphylococcus aureus (ATCC215223), Streptococcus pneumonia (ATCC49619), Streptococcus pyogenes (ATCC19615), Escherichia coli (ATCC259292), Klebsiella pneumonia (ATCC70060), Pseudomonas aeruginosa (ATCC27853), and Salmonella typhi (ATCC1912/R). Well, the diffusion method was used to perform the antibacterial screening. Determination of minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and phytochemical screening was also done on the extracts. Results indicated that the different extracts displayed significant (P<0.05) antibacterial activities and the methanol extract were more active. Flavonoids, glycosides, phenols, saponins,...

Plants are valuable sources of natural products. Despite the availability of different approaches for the discovery of therapeutically, natural products remain as one of the best reservoirs of new structural types. They play a major role in the cure of various diseases from ancient time. Role of plant metabolites to inhibit the growth and activity of pathogenic bacteria is cherished. Research towards the invention of sources of plant metabolites gives sustenance against the problem of development of resistant pathogen. The review presents information about some new sources of phytometabolites against...
