Comparison of the chemistry and diversity of endophytes isolated from wild-harvested and greenhouse-cultivated yerba mansa (Anemopsis californica)

- Fourteen fungal endophytes were isolated from yerba mansa (Anemopsis californica).
- Chaetomium cupreum yielded a new antimicrobial spirolactone, chaetocuprum.
- Endophyte diversity was higher from wild-harvested than cultivated roots.
- Results indicate the importance of source material for endophyte drug discovery.
