Abstract



Isolates of four polypores; Ganoderma colossum, Ganoderma lucidum, Trametes cingulata and Daedalea quercina were compared using the High performance liquid chromatographic profiles of their triterpenoids. A higher abundance of colossolactone E was found in Ganoderma colossum isolate (FC 876) when compared with FC 872 obtained at different periods and dried differently and 23- hydroxycolossolactone E found in FC 876 was not observed in FC 872. Equal abundance of constituents was also found in Ganoderma lucidum isolates (FC 871 and FC 875) collected from different hosts and geographical locations. The isolates of Trametes cingulata that were of different ages showed predominance of the major constituents in FC 873 and FC 885 isolates when compared with FC 870. The abundance of the triterpenoid in the isolates of Daedalea quercina was almost doubled in FC 882 when compared with that of FC 878. These conform with the chemical spot test results on these polypores in a previous work. The ability of the polypores to produce triterpenoids is affected by their age, period of collection, geographical location and method of drying, which also affected the High Performance Liquid Chromatography characteristics of their secondary metabolites.
