Plectranthus Amboinicus

Plectranthus amboinicus or locally known as bangun-bangun, is an indigenous vegetable which can be freshly eaten. However, the plant is unpopular among local people and being neglected. It has been reported to be traditionally used for medicine to cure common illnesses such as cough, stomachache, headache and skin infection. Based on the potential, a study was conducted to bioprospect the antimicrobial activity of the essential oil. Plectranthus amboinicus essential oil of methanol and chloroform extract was tested against nine bacteria and four fungi i.e., Escherichia coli, Proteus vulgaris, Pseudomonas aeruginosa, Shigella flexneri, Klebsiella pneumoniae, Enterococcus faecal, Staphylococcus aureus, Salmonella typhi, Bacillus cereus, Candida albicans, Aspergillus niger, Aspergillus fumigatus and Aspergillus flavus. The methanol extract of Plectranthus amboinicus showed the maximum antibacterial activity against the bacteria Klebsiella pneumoniae and fungi Candida albicans. The antimicrobial activity of Plectranthus amboinicus was more at 100 mg/ml concentration when compared to 50 mg/ml concentration. Comparatively, the Methanol extract of Plectranthus amboinicus exhibited maximum antimicrobial activity when compared to Chloroform extract. The Plectranthus amboinicus has showed good antimicrobial activity against most of the bacteria and only one fungal yeast Candida albicans. No zone of inhibition was recorded against other fungal isolates like Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus and Negative DMSO control.

Calanthe masuca (D.Done) Lindl is a potential medicinal plant of terrestrial orchids. Tribal peoples were used the plants for therapeutic purpose. The present study was to evaluate the phytochemical analysis and Antimicrobial Activity of Calanthe masuca in leaf extracts. Preliminary phytochemical analysis revealed that the presence of bioactive substance in leaf extract was found that Alkaloids, Flavanoids, Phenol, Tannins, Saponins, Steroids, Terpenoids, Carboxcylic acid, Glycoside and Mucilage. Antimicrobial activity by Agar well diffusion method again six pathogenic microbes such as Staphylococcus aureus, Bacillus subtilis, E.coli and Pseudomonas aeruginosa in bacteria, Aspergillus niger and Candida albicans in fungi by using different solvent such as Aqueous, Methanol and Petroleum ether. It was observered that Methanol extract showed highest activity against the pathogen such as S.aureus (13.5 mm), B.subtilis (12.4 mm), E.coli (12.5 mm) and P.aeruginosa (13.0 mm) and then followed by the Aqueous extract and low activity showed in petroleum ether extract. The methanol extract showed signicant Antifungal activity against Aspergillus niger (14.0mm) and Candida albicans (13.0 mm) with higher concentration and Petroleum ether extract showed lower activity in fungi. The capacity of the crude concentrates of Calanthe masuca to suppress the development of microorganism which means that it has a wide range of antimicrobial potential utilized for various cures.

This study was performed to evaluate the antimicrobial activity of aerial parts of chloroform extract of Cassia auriculata L. The chloroform extract of C. auriculata were shown to possess an antimicrobial activity against two gram positive and two gram negative human pathogenic bacteria and fungi, viz. Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and fungus cultures Candida albicans and Aspergillus niger by using disc diffusion method. The extract showed antibacterial activity at all concentrations selected, but only the extract with the concentration of 300µg/ml showed maximum antibacterial activity against all the organisms except Pseudomonas aeruginosa which are comparable with the standard control, amikacin. The anti fungal activity of chloroform extract of C. auriculata revealed significant effect against Candida albicans and Aspergillus niger with the net inhibition zone of 14 and 14 mm, respectively at 300µg/ml concentration, which is almost comparable with standard control, ketokonazole used as an antifungal agent. The phytochemical analysis showed the presence of alkaloids, carbohydrates, fixed oils, fats, tannins, gum & mucilage, flavonoids, saponins, terpenoids, lignin and sterols. It is concluded that the antimicrobial activity showed by the plant was due to the presence of these phytochemicals. Further studies are highly needed for future drug development.DOI: http://dx.doi.org/10.3329/icpj.v2i6.14869 International Current Pharmaceutical Journal, May 2013, 2(6): 105-108

The antimicrobial activity of methanol and aqueous extract of M. pruriens seeds was determined by well diffusion method with ATCC strains of gram positive and gram negative bacteria clinical strains of multidrug resistant (MDR) Klebsiella pneumoniae, and clinical strains of Candida albicans. It was observed that both the aqueous and the methanol extract of M. pruriens seeds had antibacterial activity against all the ATCC bacterial strains. The MDR strain of Klebsiella pneumoniae was resistant to both aqueous and methanol extract of M. pruriens seed. Antifungal activity against Candida albicans was exhibited by both aqueous and methanol extracts of M. pruriens seed.

Antifungal Potential

This study evaluates the antimicrobial and antifungal potential of the essential oil extracted from a species located in the Andes of Ecuador, Piper barbatum Kunth, known as “cordoncillo” or “allupa”, used by the Quichua people as an antibacterial plant for washing female genitalia in cases of infection. The most abundant molecules in the essential oil were: α- phellandrene (43.16%), limonene (7.04%); some oxygenated sesquiterpenes such as: trans-sesquisabinene hydrate (8.23%), elemol (7.21%) and others. The evaluation of antimicrobial activity showed activity in all the strains analyzed; however, those in which MIC values are considered to be very strong (less than 500 µg/mL) are: Staphylococcus aureus 264 µg/mL, Streptococcus mutans 132 µg/mL, Candida albicans 132 µg/mL and Candida tropicalis 264 µg/mL. Antimicrobial bioautography defines which molecules are responsible for the activity; thus, it was possible to establish the chromatographic regions of = 0.02 and Rf = 0.04, as those with active molecules. It was established that 4 hydroxylated sesquiterpene molecules are involved: elemol (7.21%), trans-sesquisabinene hydrate (8.23%), β–eudesmol (3.49%) and 10-epi-γ-eudesmol (1.07%); the last two being the most active. The aim of this manuscript is to analyze both the ancestral knowledge of the Quichua people of Ecuador, and the chemical-biodiversity of the Andean forest ecosystem, in order to provide new raw materials of pharmaceutical interest.

The chemical composition of the essential oil obtained from the aerial parts of Santolina chamaecyparissus L., growing in Algeria, was investigated by GC-MS analyses. A total of 36 compounds were identified, accounting for 91.7% of the essential oil obtained. Camphor (31.1%) and cubenol (17.0%) were the predominant compounds. The potential of the antimicrobial activity was also investigated and the tested sample proved to be very active against Klebsiella pneumonia and Candida albicans (34.1 ± 0.02 mm and 35.0 ± 0.01 mm, respectively). Transverse sections of the leaf and stem of the plant suggest that the essential oil is localized in endogenous and exogenous sites.
