Antibacterial activity plants

Documented effects The entire plant shows antibacterial activity (Plant Resources of the USSR 1991). 

Documented effects Lectins, isolated from this species, show bonding specificity with human blood type A (Sharon and Lis 2004). In experiment on animals, an infusion and decoction of the plant had antibacterial activity (Plant Resources of the USSR 1987).

PHARMACOLOGICAL ACTIVITIES AND CLINICAL TRIALS Antibacterial activity. Alcohol extract of black tea, assayed on Salmonella typhi and Salmonella paratyphi A, was active on all strains of Salmonella paratyphi A, and only 42.19% of Salmonella typhi strains were inhibited hy the extract ". Ffot water extract of the dried entire plant and the tannin fraction, on agar plate, were active on Escherichia coli. Pseudomonas aeruginosa, and Staphylococcus aureus. ...

Antibacterial activity. Methylene chloride extract of the dried aerial parts of the plants, on agar plate at a concentration of 1 g/mL, was active on Bacillus subtilis L Methanol extract of the shade-dried plant, on agar plate at a concentration of 0.6 mg/mL, was inactive on Staphylococcus aureus. A concentration of 10 mg/mL was inactive on Escherichia coli and Pseudomonas aureugi-nosab L...

Anti-amoebic activity. Ethanol (80%) extract of the dried rhizome was inactive on Entamoeba histolytica, minimum inhibitory concentration (MIC) greater than 1 mg/ mL The extract, administered intragas-trically to male hamsters at a dose of 800 mg/kg, was active vs experimentally induced hepatic amebiasis . A dose of 250 mg/kg, administered intragastrically to rats on days 1-5, produced weak activity and a dose of 500 mg/kg was active " ". Anti-atherosclerotic activity. Ethanol (50%) extract of the dried rhizome, administered intragastrically to male rabbits at a dose of 500 mg/kg, reduced atherogenic index from 4.7 to 1.2 on the aorta . Antibacterial activity. Decoction of the dried entire plant, on agar plate, was inactive on Proteus vulgaris, Staphylococcus aureus, and Staphylococcus epidermidis MIC 125 mg/mL. Bacillus subtilis, Bordetella... 

Isomarinone (1679), an isomer of the previously known marinone (7), was isolated from the same tropical sediment bacterium (1638). Another marine-derived bacterium related to the genus Streptomyces has yielded the novel azamerone (1680) (1639). The British Columbian medicinal plant Moneses uniflora contains the antibiotic 8-chlorochimaphilin (1681), which is more active than chimaphilin (1640). Sesame roots (Sesamum indicum) have yielded the red chlorinated naphthoquinone chlorosesamone (1682) (1641). Cultures of Streptomyces strain LL-A9227 produce chloroquinocin (1683), which has some antibacterial activity against Gram-positive bacteria (1642). The two xestoquinones 1684 and 1685 were characterized from the Philippino sponge Xestospongia sp., and display topoisomerase II activity (1643). 

The Streptomyces strain that produces celastramycin A (1212) has also yielded celastramycin B (2166) (1225). Another Streptomyces sp. has afforded bischloro-anthrabenzoxocinone ((-)-BABX) (2167), which has antibacterial activity and inhibits ligand-binding activity of liver X receptors (1937). An example of a rare chlorinated anthraquinone is anthrasesamone C (2168), which was characterized in the Japanese plant Sesamum indicum (1938). The angucycline-type marmycin B... 

Another Streptomyces sp. obtained from black anaerobic intertidal sediment collected near Christchurch, New Zealand was fermented in a saline medium and found to produce modest antibacterial activity against Bacillus subtil is.14 The isolation of the active compound revealed it to be an actinoflavoside, a molecule of an unprecedented structure class (Structure 18.5). Actinofla-voside resembles the common plant-derived flavonoid glycosides, but this compound contains an... 

Plants are not the only natural products used as a source for drugs. Microorganisms have, of course, been extensively screened for antibiotics since Alexander Fleming s discovery of the antibacterial activity of Penicillin notatum in the 1920s. Numerous...
