Two new metabolites from the endophytic fungus Xylaria sp. isolated from the medicinal plant Curcuma xanthorrhiza
L Hammerschmidt, A Ola, WEG Mueller, WH Lin… - Tetrahedron …, 2015 - Elsevier
The endophytic fungus Xylaria sp. was isolated from healthy leaves of Curcuma
xanthorrhiza, collected on the island of Timor, Indonesia. Two new compounds (1 and 2),
together with the known resacetophenone (3), were isolated and their structures were
elucidated on the basis of comprehensive NMR and mass spectral analyses. The
enantiomers of rac-1 were separated by chiral HPLC and their HPLC-ECD spectra were
recorded to determine the absolute configuration on the basis of TDDFT-ECD calculations …
