Abstract Besides agecorynin C, eupalestin and lucidin dimethyl ether, two new highly oxygenated flavones were isolated fromAgeratumhoustonianum . Their structures were established by spectroscopic and degradative evidence as 5, 6, 7, 8, 2′, 3′, 4′, 5′-octamethoxyflavone and 5, 6, 7, 2′, 3′, 4′, 5′-heptamethoxyflavone.

Novel derivatives of amidines of formula
wherein the substituents are defined as in the specification which are useful for inhibiting activity on NO-synthase enzymes producing nitrogen mono oxide and/or trapping the reactive oxygen species (ROS) making them useful for treating various diseases.
