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.
