“…Among the bacteria, K. pneumonia has higher value of 14 mm and P. vulgaris has lower value of 10 mm in 1 mg/ml concentration but similar effect in both gram positive and gram negative bacteria at minimum concentrations of 0.25 mg/mL (Table 3). The present observation that essential oil of A. adenophora has antibacterial activity can be correlated with study done by Kurade et al 2010 12 . Antibacterial effect of essential oils is, generally, less against gram-negative bacteria than gram-positive bacteria 13 .…”

The earlier investigation of the essential oil of E. adenophorum leaves from India shows 1-napthalenol (17.50%), α-bisabolol (9.53%), bornyl acetate (8.98%), β-bisabolene (6.16%), germacrene-D (5.74%) , α-phellandrene (3.85%) and a di-epi-α-cedrene (2.98%) 12 . Weyerstahl and co-workers from India (1997) reported the composition of the essential oil of flowers of E. adenophorum 22 .…”

“…A hepatotoxic compound (9-oxo-10, 11-dehydroagerophonrone) was identified from the crude extract of A. adenophora, this component promotes a chronic equine respiratory disease known as "Numinbah horse"and liver lesions 9 .They also found b-farnesene, germacrene D, bisabolene, caryophyllene and four more cadinene derivatives were also reported. Other compounds identified from the stems and leaves of this species were found to be 9-oxo-ageraphorone, 9-β-hydroxy-ageraphorone, epifriefdelinol, stigmasterol, octacosanoic acid, b-daucos-terol, o-hydroxycinnamic acid, ferulic acid, cafeicacid and 2-isopropenyl-5-acetyl-6-hydroxybenzo-furan acetate.There are some previous reports on the antimicrobial activity of the oils of some species of Eupatorium 10,11,12 . However, the natural products profile and consequently the bioactivity is known to vary with the climate and geographic location of the plants 13 .…”

The essential oil of Ageratina adenophora locally call Banmara was analyzed by GC-MS. A total of 45 volatile compounds was identified and torreyol (16.8%) was the major component in oil. The sesquiterpene fraction was higher than the monoterpene one. The essential oil showed significant antibacterial activity against both gram positive (Klebsiella pneumoniae and Staphylococcus aureus) and gram negative (Escherichia coli and Proteus vulgaris) bacteria.

“…This infection affects the skin, oral cavity, esophagus, gastrointestinal tract, vagina and the human vascular system (Calderone and Fonzi, 2001). The above results reveal the potential of this essential oil against pathogenic microorganisms, broadening the biological importance of the species, already known for its actions as antipyretic, antimutagenic, and insecticide, among others (Naz and Bano, 2013;Seth et al, 2012;ZandiSohani et al, 2012;Kurade et al, 2010;Sharma and Kumar, 2009;Sonibare and Effiong, 2008;Verma and Verma, 2006;Barre et al, 2005;Deena and Thoppil, 2000;Siddiqui et al, 1995).…”

Lantana camara L. is considered a weed, but is used in agriculture and traditional medicine due to its different pharmacological effects. The objective of this study was to determine the chemical composition and the bioactivity of essential oil from L. camara flowers collected in Boa Vista, Roraima, Brazil. Essential oil was obtained using a Clevenger type apparatus. The oil obtained was analyzed by gas chromatography coupled to flame ionization detector (GC-FID) and gas chromatography coupled to mass spectrometer detector (GC-MS) and its bioactivity was assayed against fungi and bacteria, as well as for acetylcholinesterase inhibition. The chemical composition of essential oil presented major compounds contrasting with the literature, while its bactericidal and fungicidal activity was excellent, reaching over than 90% inhibition against yeast. A potent anti-acetylcholinesterase activity, superior than 77% inhibition, was also observed.

“…Essential oil of Ageratum has been reported to inhibit several bacteria and fungi having more potent antimicrobial activity than citronella and geranium oils [7]. Essential oil of A. houstonianum, a close relative of A. conyzoides, has antibacterial activity against Micrococcus luteus and Rhodococcus rhodochrous with minimum bactericidal concentration (MBC) of 100 mg/ml and 12.5 mg/ml, but not against Arthrobacter protophormiae, Escherichia coli and Staphylococcus aureus [8]. However in another study [9] hexane extract, aqueous extract and methanolic leaf extract of Ageratum conyzoides inhibited one strain each of S. aureus, Yersinia enterocolitica, Salmonella gallinarum and E. coli.…”

Ageratum conyzoides, a weed prevalent in India, is known for its several therapeutic uses to control infections. In the present study we compared the antimicrobial potential of its ether extract and methanolic extract with ciprofloxacin on 294 strains of Gram positive bacteria (GPBs), 575 strains of Gram negative bacteria (GNBs), 15 yeast and 5 mould strains of clinical and nonclinical origin belonging to 49 genera and more than 155 species using disc diffusion assay. The microbial strains in the study were isolated from samples of abiotic (41) and biotic (101) environment, foods (81), clinically sick (441), dead (108) and healthy (75) animals and human beings, and 42 were reference strains. The study revealed that there was no appreciable difference in antimicrobial activity of ether extract (ACEE) or methanolic extract (ACME) of A. conyzoides. A total of 214 (24.1%) strains were sensitive to ACME while of the 697 strains tested for ciprofloxacin 551 (79.1%) were sensitive. Sensitivity to ACME among 294 GPBs (44.9%) was significantly (p<0.0001) higher than among 575 strains of GNBs (12.4%). There was no significant difference among GPBs and GNBs for ciprofloxacin (one of the most commonly used antibiotics in India) sensitivity, but oxidase negative GNBs (385) as well as GPBs (238) were about two times more commonly sensitive to ciprofloxacin than 190 oxidase positive GNBs (p = 0.001) and 56 oxidase positive GPBs (p, 0.03), respectively. For ACME oxidase positive strains had 2.4 times more odds (p < 0.0001) in their favour of being sensitive to ACME (53.4%) than oxidase negative strains (18.6%). The most sensitive strains to ACME belonged to oxidase positive GPBs (62.5%) followed by oxidase negative GPBs (40.8%), oxidase positive GNBs (27.4%) and oxidase negative GNBs (4.9%). All Aeromonas, Alcaligenes, Klebsiella, and Proteus species strains were resistant to ACME irrespective of source of isolation or association with illness. In contrast, majority of the strains of Burkholderia (76.9%), Bacillus (66.7%) and Brucella (53.8%) species were sensitive to ACME. The study revealed that A. conyzoides might be containing useful antimicrobial component(s) more active against oxidase positive potentially pathogenic strains often associated with systemic and deadly infections in animals as well as in humans.
