Analysis of bioactive chemical components of two medicinal plants (Coriandrum sativum and Melia azedarach) leaves using gas chromatography-mass spectrometry (GC-MS)

The main objective of this study was to determine the phytochemical composition in the leaves of Coriandrum sativum, using methanolic extraction and report the main functional components by using IR technique. The phytochemical compounds in the extract were then screened by GC-MS method. Seven bioactive phytochemical compounds were identified in the methanolic extract of C. sativum: 1,6- octadien-3-ol, 3,7-dimethyl, 1,6-octadien-3-ol,3,7-dimethyl, 2-aminobenzoate, bicyclo[2.2.1]heptan-2-one,1,7,7-trimethyl., geranyl vinyl ether, 9,10-secocholesta-5,7,10(19)-triene-3,24,25-triol., ascorbic acid 2,6-dihexadecanoate and 7aH-cyclopenta[a] cyclopropa[f]cycloundecene. Thirteen bioactive phytochemical compounds were identified in the methanolic extract of Melia azedarach. In the present investigation, a variety of compounds have been detected in M. azedarach including trichloromethane, propanedioic acid, diethyl ester, 2-pyrrolidinyl-methylamine, butanedioic acid, diethyl ester, 2-piperidimethanamine, butanedioic acid, hydroxyl-, diethyl ester, 2,5-dimethylhexane-2,5-dihydroperoxide, dithiocarbamate, s-methyl-,n-(2-methyl-3-oxobutyl), triethyl citrate, y-sitosterol, ethyl 9,12,15-octadecatrienoate, hexadecanoic acid,  2-hydroxy-1-(hydroxymethyl)ethyl ester, and octadecane, 3-ethyl-5-(2-ethylbutyl). It contains chemical constitutions which may be useful for various herbal  formulation as anti-inflammatory, analgesic, antipyretic, cardiac tonic and antiasthamatic. C. sativum is highly active against Aspergillus terreus 6.01 ± 0.200. Bioactive compounds of C. sativum and M. azedarach were assayed for in vitro antibacterial activity against Staphylococcus aureus, Proteus mirabilis,  Pseudomonas aerogenosa, Escherichia coli and Klebsiella pneumonia using the diffusion method in agar. The zone of inhibition was compared with different standard antibiotics. The diameters of inhibition zones ranged from 5.60 ± 0.320 to 1.96 ± 0.200 mm for all treatments.Key words: Anti-bacterial, antifungal activity, Coriandrum sativum, GC-MS analysis, Melia azedarach, phytochemicals

Mycobacterium avium paratuberculosis and Mycobacterium avium complex and related subspecies as causative agents of zoonotic and occupational diseases

Mycobacterium avium complex (MAC) and Mycobacterium avium paratuberculosis (MAP) cause zoonotic infections transmitted by birds and livestock herds. These pathogens have remained as serious economic and health threats in most areas of the world. As zoonotic diseases, the risk of development of occupational disease and even death outcome necessitate implementation of control strategies to prevent its spread. Zoonotic MAP infections include Crohn's disease, inflammatory bowel disease, ulcerative colitis, sarcoidosis, diabetes mellitus, and immune-related diseases (such as Hashimoto's thyroiditis). Paratuberculosis has classified as type B epidemic zoonotic disease according to world health organization which is transmitted to human through consumption of dairy and meat products. In addition, MAC causes pulmonary manifestations and lymphadenitis in normal hosts and human immunodeficiency virus (HIV) progression (by serotypes 1, 4, and 8). Furthermore, other subspecies have caused respiratory abscesses, neck lymph nodes, and disseminated osteomyelitis in children and ulcers. However, the data over the occupational relatedness of these subspecies is rare. These agents can cause occupational infections in susceptible herd breeders. Several molecular methods have been recognized as proper strategies for tracking the infection. In this study, some zoonotic aspects, worldwide prevalence and control strategies regarding infections due to MAP and MAC and related subspecies has been reviewe
