ABSTRACTPhaseoulus lunatus L., a variety of baby lima bean, which is produced in the coastal region of Ecuador, is a profitable crop of that country. Various cultivars of this common bean are considered a sources for nutraceutical compounds, such as bioactive peptides. To assess the potential biologic activities of protein isolates and hydrolysates of P. lunatus baby lima beans, this study evaluates the proteins antimicrobial, antioxidant and anti-inflammatory activities. Antioxidant activity was measured by the TBARS method. In-vitro anti-inflammatory activity was measured by the inhibition of denatured protein as well as a diffusion method, according with CLSI guidelines by antimicrobial activity. Both fractions (isolate and hydrolysates) showed anti-inflammatory and antioxidant activity. However, protein hydrolysates (pH 5) had a better performance than protein isolates. The same effect was observed in antimicrobial activity, when protein hydrolysates had a broad-spectrum antimicrobial activity against Gram-negative and Gram-positive bacteria. These preliminary studies suggest that P. lunatus baby lima beans could have a considerable biological activity for nutraceutical applications.

Abstract Background Mahanintangtong is listed in the Thailand’s National List of Essential Medicines (NLEM). It is used to treat non-specific fevers and illnesses such as pharyngitis and chickenpox. In this study, we investigated the biological activities of the different medicinal plants used in the Mahanintangtong formula. Methods The plant materials were extracted by maceration and decoction. Antimicrobial activity, assessed by disc diffusion method, the minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) were compared with commercially available standard antibiotics. To elucidate the anti-inflammatory mechanisms, inhibition of nitric oxide (NO), tumor necrosis factor α (TNF-α), and interleukin 6 (IL-6) production was tested by Griess and ELISA techniques. Antioxidant activity was measured by ABTS and DPPH scavenging assays. Results The extracts with the best antimicrobial activities were carbonized Tectona grandis showing against Streptococcus pyogenes, Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa. The ethanol extract of Dracaena loureiroi wood exhibited the highest NO and IL-6 inhibitory activity with IC50 values of 9.42 ± 1.81 and 12.02 ± 0.30 μg/mL, respectively. The ethanol extract of Pogostemon cablin had the highest TNF-α inhibitory with IC50 values of 10.68 ± 0.02 μg/mL. In anti-free radical testing, the ethanol extract of D. loureiroi displayed high antioxidant activity by both ABTS and DPPH assays. Conclusion The ethanol extracts from carbonized T. grandis and Mahanintangtong showed good antimicrobial activity, especially against S. pyogenes, and good anti-inflammatory activity. These findings are relevant to the pathogenesis of pharyngitis and justify additional studies to see if Mahanintangtong could have clinical utility.

Our study is intended to prepare and evaluate the polyherbal formulation (PHF) using Nyctanthes arbor-tristis, Piper nigrum, and lemon juice. Poly Herbal Formulation F1 and F2 were synthesised and subjected to qualitative, quantitative phytochemical analysis and antioxidant activity was measured using a standard protocol. Antimicrobial activity of PHFs was observed by the agar well diffusion method. The anti-inflammatory and anti-diabetic activities (In-vitro) were studied in F1 by using inhibition of albumin denaturation method. TLC and FTIR are done for the structural elucidation in F1. The F1 and F2 exhibited the presence of flavonoids, alkaloids, tannins, phenols, terpenoids, carbohydrates, saponins, Glycosides and proteins. The F1 and F2 show significant activity against the standard in the antimicrobial and antioxidant activity. The presence of flavonoids and alkaloids may contribute to the anti-microbial activity. The Nitric oxide radical scavenging activity and a metal chelating assay of the F1 possess the highest antioxidant activity of 73.1% and 69% respectively. TLC confirms the presence of flavonoids in F1. FTIR spectrum shows the functional group of amines, alcohols, nitrites, aromatic and aliphatic compounds. These FTIR bands denote stretching and vibrational bands responsible for the compounds like flavonoids, terpenoids, phenols and amino acids. This investigation shows the excellent result in antimicrobial, antioxidant and in-vitro anti-diabetic and anti-inflammatory activities. In future, the PHF of F1 can be used as potent therapeutical agents and can be further exploited for their other beneficial effect in the pharmacological studies.

Ethanolic extracts of Pergularia tomentosa L. were used for the relative analysis of antioxidant and antimicrobial activity against two types of Gram-negative bacteria. (Escherichia coli G (-) and Pseudomonas aeruginosa G (-)) and a gram positive (Staphylococus aureus G (+)). Maximum activity was recorded against Escherichia coli, with a maximum inhibition diameter of 23mm using the disk diffusion method. In addition, the results revealed a higher bacterial activity against Escherichia coli with an inhibition diameter of 23mm compared to standard antibiotics Ampicillin/Nystatin with an inhibition diameter of 11.75mm. The study of the antioxidant activity by the DPPH and FRAP methods showed that vitamin C is the most active with an IC50 equal to 0.010 g/ml, followed by the crude extract, with a value of 0.012 g/ml and finally Tocopherol (VE) which seems to be the least effective with an IC50 of 0.015 g/ml. The results obtained in the present study suggest that Pergularia tomentosa L. can be used in the treatment of diseases caused by the organisms tested. Further chemical and pharmacological investigations can be carried out to isolate and identify the chemical constituents in selected plants responsible for antimicrobial activity.
