Pycnarrhena cauliflora (Miers.) Diels., local name sengkubak, is one of indigenous plants from West Kalimantan that has been used as natural flavor. Pycnorrhena cauliflora is one of species of Menispermaceae family which is rich in bisbenzylisoquinoline alkaloids. This alkaloids are known to have various biological activities including antiprotozoal, antiplasmodial, antifungal and antibacterial activities. This study aimed to investigate antimicrobial activity of  the P. cauliflora (Miers.) Diels. methanolic extracts against gram-positive and gram-negative bacteria. The methanolic extract of P. cauliflora (Miers.) Diels., root, leaf and stem were prepared by maceration. The disk-diffusion method was then used to determine the antimicrobial activity of the extracts against Streptococcus pyogenes, S. mutants, Staphylococcus aureus, S. epidermidis, Salmonella typhi, Shigella flexneri, Pseudomonas aeruginosa and Escherichia coli after 18-24 h incubation at 37 oC. Amoxicillin was used as positive control for gram-positive bacteria and ciprofloxacin was used as gram-negative bacteria. The inhibition zones were then measured in mm. Analysis were conducted in duplicates. The results showed in general the methanolic extracts of P. cauliflora (Miers.) Diels. root (inhibition zone diameter= 10-23 mm) were more active than that leaf (0-15 mm) and stem (0-17 mm) extracts against gram-positive bacteria. The zone inhibition diameter of amoxicillin as positive control was 8-42 mm. In addition, the methanolic extracts of P. cauliflora (Miers.) Diels. root (12-17 mm) were also more active than that leaf (0-12 mm) and stem (0-12 mm) extracts against gram-negative bacteria. The zone inhibition diameter of ciprofloxacin as positive control was 33-36 mm. In conclusion, the methanolic extract of P. caulifloria (Miers.) Diels. root is the most extract active against both gram-positive and gram-negative bacteria. Further study will be focused to isolate active compounds in the methanolic extract of the root.

AbstractObjective: Scientists are looking for new resources which have biological activities. The present study was planned to evaluate the antioxidant and antimicrobial activity of ethanol and acetone extracts, as well as the volatile compounds of two freshwater green algal species Spirogyra spp. and Zygnema stellinum (Vaucher) C. Agardh belonging to Zygnemaphyceae (Conjugatophyceae) obtained from Ordu University Campus wetlands.Methods: The extracts were tested in vitro for their antimicrobial effects using disc diffusion method. Total phenolic content and the antioxidative activity according to FRAP and DPPH methods of the extracts were also determined. The secondary metabolites from the investigated extracts were identified using GC-MS.Results: The extracts dramatically inhibited almost all tested microorganisms. The antimicrobial activity of the acetone extract of the Zygnema against C. albicans was found as more higher than positive control Nystatin. In accordance with antimicrobial activity, the highest total phenolic content was also determined in the presence of the acetone extract of the Zygnema. Furthermore the highest FRAP value and the lowest EC50 (mg/mL) value were calculated for the same extract. The main components of the all consisted of dimethyl and diethyl ester of 1,2-benzenedicarboxylic acid. However, the abundance of these metabolites in the extracts was not associated with antimicrobial or antioxidant activity. Biological activities of these algal species could be attributed to chemicals such as 1-Pentadecene and 1-Tetradecene which were present in smaller amounts.Conclusion: Investigated algal species can be evaluated to use in biotechnological applications such as food industry and medicine.

Popularly known as red mandioqueira, ‘mandioqueira vermelha’, Qualea paraensis Ducke is a plant species belonging to the family Vochysiaceae, with a natural distribution in the Amazon region. It is used in traditional medicine, by native communities of the Amazon and Bolivia, for the treatment of skin lesions caused by microorganisms. Previous studies of the species have found antimalarial activity in vivo assays. However, studies involving the investigation of numerous biological activities of Q. paraensis are incipient. Biological assays already performed with plants of other species of the genus Qualea have shown promising biological activities. Therefore, this study describes the evaluation of the biological activities (bactericide, fungicide, toxicity, and anticholinesterase) of an ethanolic extract of the bark of Q. paraensis from the state of Roraima, Brazil. For the evaluation of the toxicity of the extract, a system with microcrustacean Artemia salina was used. Antimicrobial activity was tested for the pathogenic groups of fungi (Aspergillus flavus and Fusarium proliferatum), Gram-negative bacteria (Escherichia coli and Salmonella tiphymurium), and Gram-positive bacteria (Staphylococcus aureus and Streptococcus sanguinis). The potential of the extract for the inhibition of the enzyme acetylcholinesterase (AChE) was also evaluated. The assays for determining the antimicrobial activity for Gram-positive bacteria revealed satisfactory IC50 (29.98μg/mL) inhibition values for S. sanguinis strains, showing inhibition of 64.6% of their growth. The assay for S. aureus, however, presented low inhibition. For Gram-negative bacteria, there was moderate inhibition of E. coli strains. The extract showed low toxicity to A. salina and inhibition of 23.66% of the AChE enzyme.

Plectranthus neochilus Schltr. (Lamiaceae) is a plant recently introduced in Cuba. Worldwide, it is an ethnomedicinal alternative for its use against microbial infections, but the Cuban population use the extracts to treat sleep disorders. To address this apparent incongruity, four collections (from different seasonal conditions in the year) of Cuban P. neochilus cultivars were analyzed in terms of their pharmacognostic characteristics. Three extracts using fresh and dried leaves were chemically and biologically characterized. UPLC-DAD-MS/MS analysis was performed to determine their chemical composition, while a panel of nine microorganisms was used to evaluate their antimicrobial activity. Finally, cytotoxic effects of different fractions were measured in three cell lines by the resazurin viability assay. In contrast to previously reported micro and macromorphological properties of P. neochilus, the leaves from the Cuban cultivars did not present glandular trichomes, nor did they produce quantifiable levels of essential oils. Moreover, aqueous extracts used by the population revealed no significant antimicrobial activity and were not cytotoxic. The three extracts showed a similar phytochemical composition, i.e., eight flavonoids, seven abietane diterpenes, and rosmarinic acid as the major constituent, most of them reported for the first time in this species. The low yield of essential oil, the absence of glandular trichomes, compounds with a high level of oxidation, and a moderate antimicrobial activity detected were the most distinctive pharmacognostic and biological characteristics of P. neochilus grown in Cuba. These aspects could explain its non-use as an antimicrobial.

Aims: The need to find new antimicrobial agents to cope with this phenomenon increases. Background: Infection diseases are illness caused by different microorganisms, such as bacteria, among those caused by resistant bacteria are associated with greater morbidity, mortality and cost of the treatment than those caused by sensitive bacteria of the same species. Objective: Need to find new antimicrobial agents to cope with this phenomenon increases. Method: This work carried out the study of biological activities of Cissus incisa, taking account its traditional use. Three extracts were prepared from the leaves of this plant: hexane, chloroform methanol (1:1) and aqueous. Their antibacterial and antitubercular activities were evaluated using microdilution and alamar blue assays; respectively. Result: The chloroform/methanol extract (1:1) was the most active of the three tested extracts for antimicrobial activity. In this way, the extract exhibits a broad spectrum of antimicrobial activity, against the Gram positive and Gram negative bacteria tested, with MIC values between 125 to 500 μg/mL. Conclusion: This research contributes both to the knowledge of the Mexican flora, as well as the discovery of potential antibacterial agents derivate from plants.

There are many single drug and compound formulations prescribed for Jwara (~ fever) in Ayurvedic classics. Tribhuvanakirti Rasa (TKR), Godanti Bhasma (GB) and Sudarshana Ghana Vati (SGV) are widely used compound formulations that are separately indicated for the treatment of Jwara (~fever) in different dosage schedules. In Ayurvedic Formulary of India Tribhuvana-Mishrana (TM) has been chiefly indicated in treatment of Sarva Jwara (~ fever). Therefore, in this study comparative antimicrobial activity of TM and its individual ingredients viz. TKR, GB and SGV were evaluated against four fever-causing microbes such as gram-positive bacteria Staphylococcus aureus and the gram-negative bacteria Salmonella typhii, Escherichia coli and Pseudomonas aeruginosa. The aqueous extract of all the four samples (formulation as whole and the three individual ingredients separately) in a dose 125mcg/ml were tested for their antimicrobial activity against four different microbes by agar well diffusion method. The study shows that TM and its ingredients independently show significant antimicrobial activity. S. aureus was found to be most sensitive to SGV and moderately sensitive to TKR and TM while S. typhii was found to be most sensitive to TM as compared to others. TKR was found to be most effective against E.coli while SGV and TM both showed significant antimicrobial effect against E. coli. TM could provide an alternative to synthetic antibiotics against human microbial infections.

Twelve compounds of mono methyl and symmetrical dimethyl substituted benzhydrol and benzophenone were synthesized using standard synthetic procedures and screened for possible antimicrobial activity against thirteen known Gram-positive and Gram-negative bacteria, as well as two yeasts. Most benzhydrol and benzophenone derivatives under investigation demonstrated some antimicrobial activity, with ortho-methylbenzophenone, dapsone, meta-dimethylbenzophenone, and para-dimethylbenzyhydrol showing the greatest inhibition. Only four compounds, ortho-methylbenzhydrol, para-methylbenzhydrol, para-methylbenzophenone, and para-diaminobenzophenone, completely lacked antimicrobial activity. An Analysis of Variance (ANOVA) showed a significant difference between both the microorganisms and the chemical compounds used, which may provide insight into novel compounds to combat infections in humans and animals.

The effect of ionized aqueous solutions (anolytes and catholyte) in the processing of fruits (cherries, morellos, and strawberries) for decontamination has been tested. Freshly prepared analytes and catholyte without the addition of salts were used, as well as stored for 7 months anolytes, prepared with 0.5% NaCl and a combination of 0.5% NaCl and 0.5% Na2CO3. The anolyte prepared with a combination of 0.5% NaCl and 0.5% Na2CO3, as well as the anolyte obtained with 0.5% NaCl, exhibit high antimicrobial activity against the surface microflora of strawberries, cherries, and sour cherries. They inactivate E. coli for 15 minutes. The other species of the fam. Enterobacteriaceae were also affected to the maximum extent, as is the total number of microorganisms, especially in cherries and sour cherries. Even stored for 7 months, they largely retain their antimicrobial properties. Anolyte and catholyte, obtained without the addition of salts, showed a lower effect on the total number of microorganisms, but had a significant effect on Gram-negative bacteria, and especially with regard to the sanitary indicative E. coli.
