“…It has been reported that ginger (rich in sesquiterpenes) essential oils possessed a wide spectrum of antimicrobial activity (Baratta et al, 1998;Singh et al, 2008;Anwer, 2009). The obtained results corroborated with the earlier reported data of Daw et al, (1994) and Farag et al (1989b). In general, the extract of antimicrobial mechanism of essential oils has not been completely elucidated.…”

“…In general, the extract of antimicrobial mechanism of essential oils has not been completely elucidated. However, it has been proposed that the chemical structure of essential oils or their main could play an important role for the antimicrobial activity (Farag et al, 1989b;Daw et al, 1994), which may enable them to destroy the cellular structure leading to death. Therefore, the bioactivity of essential oils is dependent not only on the major compounds but also on the chemical structures of these compounds (Farag et al, 1989 b, c).…”

INTRODUCTION Throughout the ages, man has been able to rely on nature to provide for his basic needs: food, shelter, clothing and also for his medical needs. The therapeutic use of the extraordinary virtues of plants for the treatment of all diseases of man is very old and evolves with the history of mankind. Still today, a majority of the world's population, especially in the developing countries development, is only treated with traditional herbal remedies. The modern pharmaceutical industry itself is still relying on the diversity of plant secondary metabolites to find new molecules with unprecedented biological properties. This source seems inexhaustible since only a small part of the 400 000 known plant species have been investigated phytochemically and pharmacologically, and each species may contain up to several thousand different constituents (Hostettmann et al., 1998). Ginger is grown in sunny and tropical areas, mainly in Asia (India, China, Nepal). There are written records of its use dating back more than 3,500 years, but it seems that its qualities have been known for more than 5,000 years. He is known in our regions thanks to the Mediterranean trade of Romans and Greeks. It is often used as a spice to decorate dishes. In Malaysia and India, where ginger comes from, it is a well-known medicinal plant, especially in Indian Ayurveda medicine which is very old. Today, it is used worldwide to treat intestinal disorders, flu-like conditions and depressed health. Ginger consists of two parts: the underground part, called the rhizome, is gnarled and branched and the aerial part is formed of leaves and a stem about one meter in height. The rhizome, whose pulp is yellow inside, serves as a reserve for the plant and ensures its survival. The leaves are alternate, lanceolate and fragrant and the flowers are yellow with a red lip. The fruits contain few black seeds. Ginger multiplies and reproduces itself rather thanks to the division of its rhizome. It needs a wet, warm and sunny weather to grow, which is why it is usually found in tropical countries.

Antimicrobial and Antioxidant Activities of New Metal Complexes Derived from 3-Aminocoumarin

et al. 2011

3-Aminocoumarin (L) has been synthesized and used as a ligand for the formation of Cr(III), Ni(II), and Cu(II) complexes. The chemical structures were characterized using different spectroscopic methods. The elemental analyses revealed that the complexes where M=Ni(II) and Cu(II) have the general formulae [ML2Cl2], while the Cr(III) complex has the formula [CrL2Cl2]Cl. The molar conductance data reveal that all the metal chelates, except the Cr(III) one, are non-electrolytes. From the magnetic and UV-Visible spectra, it is found that these complexes have octahedral structures. The stability for the prepared complexes was studied theoretically using Density Function Theory. The total energy for the complexes was calculated and it was shown that the copper complex is the most stable one. Complexes were tested against selected types of microbial organisms and showed significant activities. The free radical scavenging activity of metal complexes have been determined by measuring their interaction with the stable free radical DPPH and all the compounds have shown encouraging antioxidant activities.

“…The antimicrobial effects of D. moldavica essential oil were measured against 4 grampositive and 2 gram-negative bacteria and factors such as quantitative and qualitative activities related to inhibitory including cloud, cloud diameter, and MIC rate were evaluated. MIC was shown for bacteria, at the scope of 26 -36 (18,19).…”

The Effects of the Ethanol Extract of Dracocephalum Moldavica (Badrashbu) Against Strains of Antibiotic-Resistant Escherichia coli and Klebsiella pneumonia

et al. 2017

Background: Today, due to the increased drug resistance, plants are used for treatment. The aim of this study was to investigate the effect of ethanol extract of Badrashbu (Dracocephalum moldavica) against strains of antibiotic-resistant Escherichia coli and Klebsiella pneumonia. Methods: Badrashbu plant extracts were prepared using a rotary device. Escherichia coli and Klebsiella pneumonia were isolated from nosocomial infection patients at hospitals of Zabol. The MIC and MBC of Badrashbu extracts in different concentrations of bacteria were determined by disk diffusion method. Results:The results of plant extracts showed that the highest MIC (minimum inhibitory concentration) for E. coli isolates was 20 milligrams per milliliter, and 6 strains were inhibited at this concentration. The highest MIC for K. pneumonia was 40 milligrams per milliliter, and only one strain was inhibited at the concentration. This result can be used to treat the disease. Conclusions:The results of this study showed that Badrashbu extract inhibits Escherichia coli and Klebsiella pneumonia; so it can be used to reduce the plant disease.
