Pheonolic compounds of convolvulus arvensis l.and their related pharmacological activity

Abstract EN

The three organs of Convolvulus arvensis L.

(flower, green parts and root) were phytochemically studied for their phenolic compounds content.

Four coumarin compounds were isolated and identified as umbeliferone, scopolamine, asculetin and scopoline for the first time from the plant.

Eleven flavonoidal compounds were isolated for the first time from different plant organs and identified by using 1H NMR, 13C NMR HMQC and UV shift reagent, these compounds were kaempferol, kaempferol-3-rutinoside, kaempferol-7-rutinoside, kaempferol-7-glucoside, kaempferol-3-glucoside, kaempferol- 3-rhamnoside-7-glucoside, kaempferol-3-galactorhamnoside, quercetin, quercetin-3-rhamnoside, quercetin-3-rutinoside and kaempferol-3-rhamnoside.

A quantitative estimation of the total flavonoids in methanolic extracts of the three organs of the plant were carried out by spectrophotometic method.

Pharmacological screening in addition to the side effects on both liver and kidney functions were carried out for different plant organ extracts.
