Bioactivity-guided isolation
WebTherefore, a phytochemical investigation of AMS was undertaken through a bioactivity-guided fractionation approach. The active components of the most active fraction were further defined as a mixture of phorbol esters, and, moreover, the new active phorbol ester possessing polyunsaturated fatty acid (1) was isolated. WebFeb 1, 2024 · Although, the bioactivity guided isolation, against either cancer cell lines or T. brucei, pointed to fraction (90–135) as inactive, isolation attempts were made considering its highest yield (2.7 g) and to identify other chemical structures which would be screened against other microorganisms i.e. Mycobacterium marinum (unpublished data).
