Secondary Metabolites of Endophytic Fungus Trichoderma harzianum Isolated from Physalis angulata
To study the secondary metabolites of the endophytic fungus
Trichoderma harzianum
which was isolated from
Physalis angulata
.
Method:
2
The strains were cultured in a big-scale by oscillating incubator. Then the obtained culture liquid and mycelia were extracted by EtOAC and actone
respectively. The extracts were integrated after recovery of solvents
and then the active secondary metabolites were isolated and purified by comprehensive use of open ODS flash column
sephadex LH-20
HPLC
and LC-MS analysis techniques. Their structures were identified according to their physico-chemical properties and nuclear magnetic resonance (NMR) data. The cytotoxicities of the compounds were determined by methyl thiazolyl tetrazolium(MTT) assay.
