Flavonoids of the aerial part of Scutellaria immaculata

Chrysin-7-O-glucuronide, scutellarein-7-O-glucoside, apigenin-7-O-glucoside, baicalein-7-O-glucoside, norwogonin-7-O-glucoside, oroxyloside, wogonoside, and the new glycoside immaculoside-5,8-dimethoxy-7-O-beta-D-glucopyranosylflavone were isolated for the first time from the aerial part of white skullcap (Scutellaria immaculata Nevski). The structure of the last was established using chemical transformations and spectral data.
