Methoxylated flavonols and flavanones from Eupatorium odoratum.
From the NaOH-soluble fraction of the C (6)H (6) extract of Eupatorium odoratum growing in Nigeria, four known methoxylated flavonols and flavanones were isolated and identified as isosakuranetin, kaempferide, sakuranetin and tamarixetin. A discussion of the flavonoid pattern in the hitherto studied Eupatorium species is also presented.
