Antibacterial and phytochemical studies on twelve species of Indian medicinal plants
No full textThe aqueous and methanol extracts of 12 plants each belonging to
different families were evaluated for antibacterial activity against
medically important bacteria viz. B. cereus ATCC11778 , S. epidermidids
ATCC12228 , E. aerogenes ATCC13048, P. vulgaris NCTC 8313, S.
typhimurium ATCC 23564. The in vitro antibacterial activity was
performed by agar disc diffusion and agar well diffusion method. The
aqueous extracts were inactive but methanol extracts showed some degree
of antibacterial activity against the tested bacterial strains. S.
typhimurium was the most resistant bacteria while B. cereus was the
most susceptible bacteria. Amongst the plant species screened, methanol
extract of Bauhinia variegata bark showed best antibacterial activity
In-vitro Antimicrobial Activities of Extractsof Launaea procumbens Roxb. (Labiateae), Vitis vinifera L. (Vitaceae) and Cyperus rotundus L. (Cyperaceae)
No full textThe aqueous and ethanolic extracts of Launaea procumbens Roxb.
(Labiateae), Vitis vinifera L. (Vitaceae) and Cyperus rotundus
L. (Cyperaceae) were evaluated for antimicrobial activity
against clinically important bacteria viz. Alcaligenes faecalis
ATCC8750, Bacillus cereus ATCC11778, Bacillus subtilis
ATCC6633, Enterobacter aerogenes ATCC13048, Escherichia coli
ATCC25922, Klebsiella pneumoniae NCIM2719, Proteus
mirabilis NCIM224, Proteus vulgaris NCTC8313,
Pseudomonas aeruginosa ATCC27853, Pseudomonas pseudoalcaligenes
ATCC17440, Salmonella typhimurium ATCC23564, Staphylococcus aureus
ATCC25923, Staphylococcus epidermidis ATCC12228,
Staphylococcus subfava NCIM2704 and Candida tropicalis
ATCC4563. The in vitro antimicrobial activity was performed by agar
disc diffusion and agar well diffusion method. The ethanolic extracts
of all the plants were active against all the investigated bacterial
strains while all the aqueous extracts were inactive except for Vitis
vinifera L. S. typhimurium was the most resistant bacterial strain
against all the extract

Indian medicinal herb: Antimicrobial efficacy of Mesua ferrea L. seed extracted in different solvents against infection causing pathogenic strains
No full textAbstractObjectiveTo study the antimicrobial potential of Mesua ferrea (M. ferrea) L. seed extracts employed for antimicrobial assay.MethodsThe plant powder was extracted in seven different solvents of increasing polarities against a wide spectrum of microbial strains. Agar disc diffusion method was employed for antimicrobial assay at the concentration of 500 μg/disc. Gram-positive bacteria were most susceptible and yeast was most resistant. The pronounced antimicrobial activity was with the extracts in non-polar solvents than in polar ones.ResultsThe results were compared with the zones of inhibition produced by commercially available standard antibiotics. The lipophilic extracts of M. ferrea L. showed more activity towards Gram positive bacteria.ConclusionThese results indicate that activity could be attributed to the presence of essential oil, xanthones and coumarines present within the seed of this plant. These results indicate that M. ferrea extract could be useful in fighting emerging drug-resistant microorganisms
Evaluation of antibacterial activity and phytochemical analysis of Bauhinia variegata L. bark
No full textBauhinia variegata L. bark powder was defatted with petroleum
ether. The non-defatted plant material as well as the defatted plant
material was then individually extracted in different solvents with
increasing polarity viz. 1,4-dioxan, acetone, methanol,
dimethylformamide (DMF) and distilled water respectively. The
extractive value of B. variegata L. for non-defatted extracts ranged
from (0.7-13%) and for defatted extracts the extractive value ranged
from (1-10.5%). The antibacterial activity of all the extracts
(non-defatted and defatted) of Bauhinia variegata L. bark was
determined by agar well diffusion method at three different
concentrations i.e., 10 mg/ml, 5 mg/ml and 2.5 mg/ml. The antibacterial
activity of defatted extracts of Bauhinia variegata L. was more than
those without defatting. Maximum activity was observed at highest
concentration i.e. 10mg/ml. Defatted acetone and methanol extracts of
Bauhinia variegata L. were most active as compared to other extracts
against all the studied organisms. Petroleum ether extracts of Bauhinia
variegata L. was inactive against all microorganisms
