Cytotoxic properties of compounds 1 - 5 were evaluated against murine leukemia P-388
cells according to the method described previously [II], showing their IC so were 10.52, 13.27,

12.99, 33.18, and 67.69, respectively. Compounds 1 -- 3 ex hibited strong cytotoxic properties
while compound 4, the unisoprenylated flavonoL was weakl y active, and compound 5 was
inactive. Thus, C-isoprenylation at the rings A and B of the flavonol greatly enhances its
cytotoxic properties. The presence of a pyran ring in compound 1 could be important for
cytotoxic activity.
Conclusion
Five compounds have bcen isolated from Mocoranga Cll7denoceras, one of them is new
co mpound, namely macaflavonol FOllr known compollnds are glyasperin A, brollssonol E,
Kaempferol , and Quercetin. Macafl avonol, glyasperin A, and brollssonol E exhibited strong
' ytutoxic properties \vhile Macaflavonol have highest activity, with IC so 10,52 pM . Kaempferol
weakly active and Quercetin was not active. PresencL.: of pyran ring in maca flavon ol could be
Important for cytotoxic activity.
