Chromatography and bioautography of endophytic fungi extracts of Uncaria tomentosa (Willd.) DC with antibacterial activity

Endophytic fungi of different species have already proved their efficacy against a range of pathogenic bacteria. However, the separation of the compounds contained in these extracts that actually have an effective activity is not a constant, but it is essential for the scientific knowledge to formulate a new medication. Thus, this study aimed to separate compounds from two endophytic fungi extracts of Uncaria tomentosa...
