Two new iridoids from Patrinia scabra.
From the roots of Patrinia scabra two new iridoids, 3-methylbutyric acid 7-hydroxy-7-hydroxymethyl-4-(3-methyl-butyryloxymethyl)-6-oxo-1,6,7,7a-tetrahydrocyclopenta[c]pyran-1-yl ester (1) and 6-hydroxy-7-methylhexahydrocyclopenta[c]pyran-3-one (2) have been isolated. Their structures were determined by means of NMR spectra and X-ray crystallographic analysis.
