title: Studies on the constituents of roots of Scutellaria planipes.
abstract: From the roots of Scutellaria planipes (L.), three new flavonoids, 5,7,3',6'-tetrahydroxy-6,8,2'-trimethoxyflavone, (2 R,3 R)-3,5,7,2',5'-pentahydroxyflavanone and 7,2'-dihydroxy-5-methoxyflavone were isolated, together with ten known flavonoids, skullcapflavone I, wogonin, baicalein, norwogonin, viscidulin III, 5,7,2',6'-tetrahydroxy-flavone, 3,5,7,2',6'-pentahydroxyflavone, wogonin 7- O-beta- D-glucuronide, baicalin, baicalein 7- O-beta- D-glucopyranoside, and three phenethyl alcohol glycosides, acteoside, martynoside, and jionoside D. The structures were elucidated by spectroscopic methods.
