Abstract
The cytotoxic compound moronic acid (1) and the new tetracyclic triterpene 3,4-seco-olean-18-ene-3,28-dioic acid (2), were isolated from the aerial parts of the medicinal plant Phoradendron reichenbachianum (mistletoe, Loranthaceae) through a bioassay-guided fractionation. In addition, squalene, glycerol trilinoleate, morolic acid, betulonaldehyde, betulinaldehyde, α-germanicol, lupeol, β-sitosterol and β-sitosteril glucopyranoside, were identified in this plant species. The structures were elucidated on the basis of chemical and spectroscopic evidence.
