“…Only Adams identified 22.7% of limonene from the plant samples collected from Greece [44] . The findings of Unlu et al were in conformity with our results [45] . The plant species is same but the percentage compositions of the major components are in different proportions depending on the location of the plant.…”

“…The J. excelsa essential oil showed a strong antimicrobial activity against the anaerobic bacterium Clostridium perfingenes, while exhibiting moderate activity against Staphylococcus aureus, Staphylococcus pyogenes, and Candida albicans (Unlu et al, 2008). However, as far as our literature survey could ascertain, there was no report on the antimicrobial activity of J. horizontalis.…”

Nowadays, the overdose use of antibiotics and the increase of microbial resistances have made researchers to carry out more studies about the new drugs with new chemical composition. In order to produce these new drugs, different species of special plants can be useful by scientists and researchers. Base on this, the leaves and fruits of Juniperus excelsa and Juniperus horizontalis were collected from Iranian National Botanic Garden. Essential oils were isolated by hydro-distillation method. The essential oil components were analyzed by gas chromatography-mass spectrometry (GC-MS). The yields of the leaves and fruits of J. excelsa and J. horizontalis essential oils were 0/79 to 4/15% and 1/083 to 2/7%, respectively. There were 15 and 27 components in the essential oil of J. excelsa and J. horizontalis, respectively. The major compound in the essential oils obtained from the leaves and fruits of J. excelsa were α-pinene (79/95 and 89/49%, respectively). The main compound in the essential oils obtained from the leaves and fruits of J. horizontalis were sabinene (30/21 and 38%, respectively). In addition, bornyl acetate (10/66%) and delta-cadinene (3/79%) were identified as major components in the essential oil of the leaves obtained from J. horizontalis. Juniper essential oils were evaluated for the antibacterial activity against thirteen bacterial species by disk diffusion and micro dilution method. Juniper essential oils showed more antibacterial activities against Gram-positive as compared to Gram-negative bacteria species. The antibacterial activity of essential oils may be related to presence of α-pinene, limonene, and sabinene which are known to have antibacterial properties.

“…Chemotherapy has not achieved the much-required success in the eradication of microbial infection because of the antimicrobial resistance developed by most pathogenic microorganisms (Unlu et al, 2008). Bacterial infections are some of the most serious global health issues of present century (Ananth et al, 2010), they are evolving numerous mechanisms to evade antimicrobial agents (Parekh andChanda, 2007, Sharath K et al, 2016).…”

Abstract:Euphorbia antiquorum is a large shrub or small tree belonging to the largest and the most diverse family in the plant kingdom, Euphorbiaceae. E. antiquram latex was used as a classical binding agent for the kshara sutra in the management of the anal fistula. In the present study, an attempt was made to evaluate the antimicrobial properties of latex of E. antiquorum on certain microbes. The methanolic extract of the latex was prepared. The fractions of methanol extract were tested for their antibacterial activity against the Gram positive bacteria, Streptococus agalactiae and Staphylococcus aureus and Gram negative bacteria Escherichia coli and P. aeruginosa. The results revealed that the latex showed minimum inhibition only to E. coli and S. aureus. Latex did not posses antibacterial activity against S. agalactiae and P. aeruginosa. The results suggest that the E. antiquorum latex extract account for the antibacterial properties and has a potential for use as an antimicrobial agent.
