title: [Study on secondary metabolites of endophytic fungi Penicillium dangeardii].
abstract: Endophytic fungi Penicillium dangeardii, isolated from Lysidice rhodostegia Hance root, was fermented and the secondary metabolites were studied. By means of Sephadex LH-20 column chromatography, ODS column chromatography and PHPLC over the fermented culture, 5 compounds were isolated. By using ESI-MS and NMR, the structures of the compounds were determined as N-[9-(β- D-ribofuranosyl)-9H-purin-6-yl]-L-aspartic acid (1), 3-caffeoylquinic acid (2), 4-caffeoylquinic acid (3), and 5-caffeoylquinic acid (4), 3-hydroxy-benzoic acid-4-O-β-D-glucopyranoside (5).
