Background: Vanga Bhasma is said to possess antimicrobial activity (Jantughna Prabhava). Hence it was decided to evaluate the antimicrobial activity of Jarit Vanga Bhasma (JVB) prepared with special reference to Rasatarangini 18/29-33. Objectives: JVB was synthesized, analysed and its antimicrobial effects were studied in Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumonia, Escherichia coli and Candida albicans. Materials and Methods: The JVB was prepared and analyzed for the quality parameters mentioned in the Ayurvedic texts as well as the modern parameters like XRD, SEM and EDX to find out the nature of the Vanga Bhasma samples. The anti-microbial study was done to find out the anti-microbial efficacy of the JVB samples. Results and Conclusions: The adopted method for preparation of JVB was able to produce a Bhasma compatible to organoleptic parameters mentioned in the ancient texts. The obtained JVB was grayish white with the formation of the small sized particles as small as a nanoparticle which was confirmed by SEM study. XRD study confirms that Tin oxide is the major compound found in all the JVB samples. JVB showed antimicrobial activity in inhibiting the growth of Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumonia, Escherichia coli and Candida albicans with a concentration of 100mg/ml. The mean zone of inhibition was 12.33mm, 12.33mm, 14.66mm, 10.33mm and 16mm respectively. This outcome further supports the Krumighna and Jantughna properties (Anti-microbial activity) of Vanga Bhasma. Hence, JVB is said to possess Anti-Microbial activity.

Objective. To evaluate the antimicrobial activity of soft and purified propolis extracts. Study object and methods. Antimicrobial activity of soft and purified propolis extracts was determined with reference cultures of Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 33499, Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis ATCC 12459, Bacillus subtilis ATCC 6633, Bacillus cereus ATCC 8035, and fungus Candida albicans ATCC 60193. Microbiological tests were performed under aseptic conditions. Minimum inhibitory concentration (MIC) – the highest dilution of preparation (the lowest concentration of preparation) that suppresses growth of reference microorganisms – was determined. Results. Concentration of phenolic compounds in soft propolis extract that possesses antimicrobial activity against gram-positive (Staphylococcus aureus, Enterococcus faecalis) and gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis) is 0.587±0.054 mg and 0.587±0.054–0.394±0.022 mg (P>0.05) and in purified propolis extract – 0.427±0.044 mg and 0.256±0.02 mg (P>0.05). Klebsiella pneumoniae is most resistant to soft propolis extract when the concentration of phenolic compounds is 1.119± 0.152 mg and to purified propolis extract when the concentration of phenolic compounds is 1.013±0.189 mg (P>0.05). Spore-forming Bacillus subtilis bacteria are more sensitive to soft and purified propolis extracts when the concentration of phenolic compounds is 0.134±0.002 mg and 0.075±0.025 mg, respectively, and Bacillus cereus – when the concentration is 0.394±0.022 mg and 0.256±0.02 mg (P>0.05). Sensitivity of fungus Candida albicans to soft and purified propolis extracts is the same as Bacillus subtilis. Encapsulated bacterium Klebsiella pneumoniae is most resistant to antimicrobial action of soft and purified propolis extracts as compared with gram-positive Staphylococcus aureus and Enterococcus faecalis bacteria (P<0.05), gram-negative Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis (P<0.05), sporeforming Bacillus subtilis and Bacillus cereus bacteria (P<0.05), and fungus Candida albicans (P<0.05). There is no statistically significant difference between antimicrobial effect of soft propolis extract and purified propolis extract on gram-positive bacteria, gram-negative bacteria, spore-forming bacteria, encapsulated bacteria, and Candida fungus. Conclusions. Soft and purified propolis extracts possess antimicrobial activity. They could be recommended as natural preservatives in the manufacture of pharmaceutical products.

Ethanol extract from the leaves of rhaponticum (Rhaponticum carthamoides D.C. Iljin) and shrubby cinquefoil (Potentilla fruticosa L.) was produced at the Department of Food Technology, Kaunas University of Technology. The antimicrobial activity of the viscous extract or rhaponticum and shrubby cinquefoil was evaluated using standard microorganism cultures (bacteria Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 33499, Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis ATCC 12459, Bacillus subtilis ATCC 6633, Bacillus cereus ATCC 8035 and fungi Candida albicans ATCC 60193). The minimum inhibitory concentration (MIC) of the examined preparations was determined. Results. Both studied preparations – rhaponticum (Rhaponticum carthamoides D.C. Iljin) and shrubby cinquefoil (Potentilla fruticosa L.) – demonstrated similar antimicrobial activity. The highest sensitivity to the studied preparations was observed in microbes with eukaryotic cell structure: Candida albicans, which is a fungus, and a spore-forming prokaryotic bacterium, Bacillus cereus. The highest resistance was observed in Escherichia coli and Klebsiella pneumoniae. Conclusions. The studied preparations – viscous extracts of rhaponticum and shrubby cinquefoil – are substances with antimicrobial activity against gram-positive (Staphylococcus aureus and Enterococcus faecalis) and gram-negative (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Proteus mirabilis) bacteria, spore-forming bacteria (Bacillus subtilis and Bacillus cereus), and fungi (Candida albicans).

Methanolic and aqueous leaf extracts of Chrysophyllum albidum (African star apple) and Garcinia kola (bitter kola) were studied for in-vitro microbial activity using the disc diffusion technique. The aqueous and methanolic leaf extracts of Chrysophyllum albidum showed antimicrobial activity against Escherichia coli, Staphylococcus aureus and Candida albicans but showed no antibacterial activity against Klebsiella pneumonia. The methanolic leaf extract of Garcinia kola inhibited the growth of Escherichia coli, Staphylococcus aureus and Klebsiella pneumonia while the aqueous extract of the leaf inhibited the growth of Staphylococcus aureus and Escherichia coli. Both methanolic and aqueous leaf extracts of the plant showed no antifungal activity against Candida albicans. The minimum inhibitory concentrations of the leaf extracts of Chrysophyllum albidum ranged from 12.5 mgL-1 to 25 mgL-1 while those of Garcinia kola ranged from 25 mgL-1 to 50 mgL-1. The results obtained suggest that the leaves of these plants can be used in treating diseases caused by the test organisms. The further investigation on the crude extracts would characterize bioactive components of the leaves of Chrysophyllum albidum and Garcinia kola.

Carbon Dioxide Extraction

The genus Lepidium L. from Brassicaceae Burnett. family covers over 150 species with an almost cosmopolitan spread. In Kazakhstan, 21 species are described, of which four species are characterized by medicinal properties (L. crassifolium Waldst. et Kit., L. perfoliatum L., L. ruderale L., and L. latifolium L.), used in folk medicine as means of antibacterial, irritant, laxative, antitumor, analgesic, and anthelmintic action. Methods. Raw materials were collected from Almaty region (Republic of Kazakhstan). Lepidium latifolium L. herb’s carbon dioxide extract (CO2 extract) was obtained by subcritical carbon dioxide extraction. A gas chromatograph with a mass spectrometric detector was used to determine the component composition of the extract. Antimicrobial activity was determined by two methods: the micromethod of serial dilution and the disc-diffusion method. Four microbial test strains were used: Staphylococcus aureus ATCC 6538-P, Escherichia coli ATCC 8739, Klebsiella pneumonia ATCC 10031, and Candida albicans ATCC 10231. Results. The technology of carbon dioxide extraction has undoubted advantages over traditional methods of extraction: it has a controlled selectivity in relation to groups of biologically active substances, allows deep extraction, and maximizes the release of rich complexes of compounds contained in plants. In this study, firstly, the CO2 extract was obtained under subcritical conditions from the aerial part of L. latifolium L., and the composition was determined. Hexane was the best solvent for CO2 extract, and 40 components were identified. Screening of antimicrobial activity of the L. latifolium’s CO2 extract showed the essential activity of all clinically significant strains tested: Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia, and Candida albicans. Conclusions. This research showed that the CO2 extract of the raw material of Lepidium latifolium L. contains biologically active compounds exhibiting an essential antimicrobial effect, and therefore it is possible to recommend for the development of various drugs for use in medical practice.

Aim: This work investigated the gas chromatography-mass spectroscopy of methanolic extract and antimicrobial spectrum of acetone and aqueous crude extracts of Ficus sycomorus stem bark. Place and Duration of the Study: Department chemistry research laboratory and microbiology laboratory, Yobe State University, Damaturu between April 2019 and August, 2019. Methodology: Pure isolates of Staphylococcus aureus, Salmonella typhi, Shigella dysentariae, proteus spp, Pseudomonas auruginosa, Escherichia coli, Bacillus subtilis, Klebsiella pneumonia and a fungi, Candida albicans were collected from National Veterinary Research Institute (NVRI), Vom, Plateau State. The plant was collected and the extract was used in preliminary phytochemical screening, GC-MS analysis and reconstituted for antimicrobial activities testing. Results: The preliminary phytochemical screening revealed presence of saponin, flavonoids, alkaloids, carbohydrates, cardiac glycoside and tannin. GC-MS analysis revealed the presence of heterocyclic members of pyrazole, imidazole, triazole, thiazole and 1, 3-Benzenedicarboxylic acid, bis (2-hethylhexyl) ester. Acetone extract showed the greatest antimicrobial activity against Bacillus subtilis, Pseudomonas aeruginosa, Proteus mirabilis and Shigella spp while the aqueous extract produced antibacterial activity against Bacillus subtilis, Staphylococcus aureus, Klebsiella pneumonia and Candida albicans. Both acetone and aqueous extracts of both stem bark extracts did not exhibit any activity against Escherichia coli. All the extracts were tested at 100mg/ml concentration. The Minimum Inhibitory Concentration (MIC) and the Minimum Bactericidal Concentration (MBC) (125 – 250 mg/ml) of both extracts were higher than those of ciprofloxacin (5.0 mg/ml). Conclusion: There is scientific basis for the uses of F. sycomorus in traditional medicine for the treatment of various diseases as prescribed earlier on and stronger basis for recommendation for its cautious use for the presence of 2-ethylhexyl which could be Carcinogenic. This is first study to identify 2-ethylhexyl from F. sycomorus stem bark extract and recommend cautious use.
