Most of the extracts tested were relatively non-toxic to human lymphocytic MT-4 cells, but extracts of some fungi exhibited potent antl-HIV activity In an in vitro 3-（4, 5-dlmethyl-2 thlazoyl）-2,5-dlphenyl-2H-tetrazollum bromide assay with a selectivity Index greater than 3. Most fungi were Isolated from Dendrobium sp. and Taxus sp.展开更多

Kuhnia rosmarinifolia Vent. is a good host for 1- or 2-year-old growing S. album. The interaction between S. album and K. rosmarinifolia is still little known. Many studies have been carried out on a number of plants for identification and diversity of endophytes. In this study, in total 25 taxa of endophytic fungi were isolated from the roots of S. album and the roots of K. rosmarinifolia. The most frequently isolated genera were Penicillium sp. 1 and Fusarium sp. 1 in the roots of S. album and K. rosmadnifolia, respectively. S. album is a root parasite of K. rosmarinifolia. The interesting result is that they apparently do not share the same endophytic fungi isolates. This study for the first time explored the content of endophytic fungi from S. album and K. rosmarinifolia, which provides important information for further studies.展开更多
