Two flavonoids from Artemisia herba-alba Asso with in vitro GABAA-benzodiazepine receptor activity.
An ethyl acetate extract of Artemisia herba-alba was partitioned by HPLC in 10 fractions that were tested in the [(3)H]-flumazenil radioligand assay, for affinity to the GABA(A)-benzodiazepine receptor. Two fractions showed activity from which hispidulin and cirsilineol were isolated. The structures were confirmed by (1)H NMR. The IC(50) values were 8 microM for hispidulin and 100 microM for cirsilineol.

Analysis of vervain flavonoids by HPLC/Diode array detector method. Its application to quality control.
A reversed-phase HPLC procedure is proposed for the determination of seven flavonoids (luteolin, nepetin, hispidulin, jaceosidin, cirsimaritin, cirsilineol, and eupatorin) in vervain samples. A simple extractive technique was developed, involving only extraction with ethyl ether, which allowed the elimination of phenolic acids, yielding a sufficiently purified flavonoid fraction. All of the analyzed vervain samples showed a common flavonoid pattern, in which hispidulin and jaceosidin were the major compounds and nepetin was the minor compound.
