Bioautography is a mean of targeted-directed isolation of active molecules on chromatogram. Bioautography is technique to detect substances affecting the growth rates to test organisms in complex mixtures and matrices. The antimicrobial, antioxidant and enzyme inhibitory activities can be performed on TLC bioautography. Bioautography methods are divided into three categories. 1)Agar diffusion or contact bioautography 2) Immersion or agar-overlay bioautography 3) Direct bioautography. High throughput method enabling analyses of many samples in parallel and the comparison of their activity. Both

Medicinal herbs such as Cosmos caudatus and Orthosiphon stamineus are sources of a huge number of bioactive compounds with antioxidant and antimicrobial properties. C. caudatus plant has bioactive compounds such as phenolics, flavonoids, and terpenoids. On the other hand, phytochemicals from O. stamineus have been shown to have a wide range of traditional applications due to their antioxidant and antibacterial characteristics. The bioautography method is used to isolate active molecules on chromatogram followed by the chemical and biological detection system. In antimicrobial bioautography, ag

Background: A simple bio-assay for determination of streptomycin hyphenated with planar chromatography techniques was developed. Objective: This study aims to validate the method for identification and determination of streptomycin in injection preparations with TLC-bioautography. Methods: Thin Layer Chromatography (TLC) was performed on the silica Gel GF-254 using KH2PO4 solution as mobile solvent. The visualization was performed by spraying 2% resorcinol. Direct bi autography was developed using Escherichia coli ATCC 25922 as a bacterial test, grown on the nutrient agar medium at 37oC for 24

Essential oils (EOs) are becoming increasingly popular in medical applications because of their antimicrobial effect. Direct bioautography (DB) combined with thin layer chromatography (TLC) is a screening method for the detection of antimicrobial compounds in plant extracts, for example, in EOs. Due to their lipophilic character, the common microbiological assays (etc. disk diffusion) could not provide reliable results. The aim of this study was the evaluation of antibacterial and anti-biofilm properties of the EO of cinnamon bark, clove, peppermint, thyme, and their main components against Ha

Plant extracts are widely utilized for their antimicrobial effect, alone or in combination with traditional drugs. However, the current global lack of harmonization on the assays used to investigate their biological effect makes the result comparison very challenging. In the present chapter, we highlight the variables used for the antimicrobial testing, which may affect the end result. The in vitro antimicrobial methods, including diffusion methods, dilution methods and thin-layer chromatography-bioautography are reported, together with a range of assays aimed at evaluating the mechanisms of a

Desorption electrospray ionization (DESI) is a technique used for direct sampling of a sample or an analyte deposited on a surface under ambient conditions [1]. In DESI, ionized droplets of a spray are directed towards the sample causing desorption of ions due to exchange of charge and momentum. The resulting ions are carried into an ion trap mass spectrometer and analyzed. DESI was originally demonstrated by Takats et al. [1]. They described the new method and applied the same to analyze various compounds present on a variety of surfaces. Followed by this, several researchers [1–5] have inves
