| in vitro studies of endophytic fungi from tripterygium wilfordii with anti-proliferative activity on human peripheral blood mononuclear cells. | an array of endophytic fungi which habitat in a chinese medicinal plant, tripterygium wilfordii hook. f., (twhf) were isolated and tested for their suppressive activity on phytohemaglutinin (pha) stimulated proliferation of human peripheral blood mononuclear cells (pbmc). out of the 343 isolates, representing 60 different morphotypes, were screened. amongst the screened fungi, only 15 isolates showed anti-proliferative activity. ethyl acetate extracts of pestalotiopsis leucothës, mucor sp. verti ... | 2004 | 15325734 |
| caryophyllene sesquiterpenoids from a fungicolous isolate of pestalotiopsis disseminata. | three new caryophyllene-type sesquiterpene alcohols, 6-hydroxypunctaporonin e (1), 6-hydroxypunctaporonin b (2), and 6-hydroxypunctaporonin a (3), have been isolated from cultures of the fungicolous fungus pestalotiopsis disseminata. the structures of 1-3 were determined mainly by analysis of 1d and 2d nmr data. the structure and absolute configuration of 6-hydroxypunctaporonin e (1) was confirmed through x-ray crystallographic analysis of its mono-bromobenzoate derivative. compounds 1 and 2 sho ... | 2006 | 16643036 |
| eucalyptus microfungi known from culture. 1. cladoriella and fulvoflamma genera nova, with notes on some other poorly known taxa. | a study of microfungi associated with living eucalyptus leaves and leaf litter revealed several novel and interesting taxa. cladoriella eucalypti gen. et sp. nov. is described as a cladosporium-like genus associated with litter collected in south africa, while fulvoflamma eucalypti gen. et. sp. nov. is newly described from leaf litter collected in spain. beta-conidia are newly reported for species of pestalotiopsis, namely pestalotiopsis disseminata in new zealand, and a pestalotiopsis sp. from ... | 2006 | 18490971 |
