TL;DR: Bioassay guided systematic fractionation of the methanol extract led to the isolation of four flavonoids which were identified as acacetin (I), apigenin (II), luteolin (III) and linarin (IV).
Abstract: The methanol extract from the whole parts of the flowers ofChrysanthemum boreale was found to exhibit a significant inhibition of rat lens aldose reductase (RLAR) activityin vitro. Bioassay guided systematic fractionation of the methanol extract led to the isolation of four flavonoids which were identified as acacetin (I), apigenin (II), luteolin (III) and linarin (IV). Compounds I–III were demonstrated to exhibit a significant inhibition of RLAR. Luteolin (III) was found to be the most potent AR inhibitor with IC50 value of 5×10−7M.

TL;DR: From the ethanolic extract of the aerial parts of Lycopus virginicus (L.) Michx.
Abstract: From the ethanolic extract of the aerial parts of Lycopus virginicus (L.) Michx. (Lamiaceae) the 7- O-beta- D-glucuronides of apigenin, acacetin, and luteolin as well as the methyl ester of apigenin 7- O-beta- D-glucuron-ide could be isolated. Quantification of luteolin 7- O-beta- D-glucuronide by HPLC in crude methanolic extracts from L. virginicus, L. europaeus, and L. exaltatus showed contents of 0.017-0.22%.
