Abstract
<p>This paper describes the influence of post-harvest processing and the cultivation year on the components of the root of Scutellaria baicalensis Georgi. The major flavonoid glycosides of Scutellariae Radix extract, baicalin and wogonoside were reduced by drying at high temperatures. The glycosides were also enzymatically hydrolyzed and C-glycoside was stable under any drying condition. Flavonoid glycosides were stored in the thin part of two-year-old roots and the bold part of one- and three-year-old roots, whereas aglycones were preserved in the bold part of two-year-old roots. However, in the freeze-dried samples unaffected by temperature and enzymatic activity, the glycosides were found in the bold roots and aglycones were found in the thin roots as expected. Furthermore, analysis of eight isolated compounds showed that wogonoside, wogonin and baicalein had potent inhibitory effects on NO production.</p>
