cytellin and 7-hydroxycoumarin

To study the chemical constituents of Pileostegia viburnoides var. glabrescens.. The compounds were isolated and purified by various techniques. Their structures were determined by physicochemical properties and spectral analysis.. Five compounds were isolated and identified as friedelin (1), beta-sitosterol (2), umbelliferone (3), daucosterol (4) and skimmin (5).. All the compounds were isolated from this genus for the first time.
