compounds produced by this species include
cylindol A, an inhibitor of 5-lipoxygenase activity (Matsunaga
et al. 1994a); cylindrene, a sesquiterpenoid with inhibitory
activity on contractions of vascular smooth-muscle (Matsunaga
et al. 1994b); graminone B, a lignan with vasodilative activity
(Matsunaga et al. 1994c); and imperanene, a phenolic compound
with platelet aggregation inhibitory activity (Matsunaga
et al. 1995). Bioactivity-guided fractionation of the methanolic
extract of the rhizomes of cogongrass yielded the compounds
5-hydroxy-2-(2-phenylethyl)chromone and 5-hydroxy-2-[2-(2-
hydroxyphenyl)ethyl]chromone that showed significant neuroprotective
activity against glutamate-induced neurotoxicity in
primary cultures of rat cortical cells
