AI Article Synopsis
- Scutellaria baicalensis Georgi, commonly known as Chinese skullcap, is a widely used herb in traditional Chinese medicine, categorized into two types: "Ku Qin" and "Tiao Qin," with the latter further graded by root diameter.
- A study analyzed six-year-old cultivated S. baicalensis to examine the distribution of five biologically active ingredients (FBAI) across different root types and sizes, revealing specific trends in ingredient content.
- Findings showed that root contents of FBAI increased and then decreased from the top to the bottom, with TST generally having higher baicalin levels, while WXR contained significantly more baicalein, wogonin, and oroxylin A;
Article Abstract
As an important herbaceous plant, Scutellaria baicalensis Georgi (Chinese skullcap) is geographically widespread and commonly used throughout the world. In the Chinese medicine market, S. baicalensis has been divided into two primary types, "Ku Qin" (WXR) and "Tiao Qin" (TST). Moreover, TST is also divided into different grades according to the diameter of roots. To explore the distribution patterns of the contents of five biologically activate ingredients (FBAI), we used six-year-old cultivated S. baicalensis and analyzed its growth characteristics as well as the quality difference among different types and diameters in roots. Throughout the entire root, we discovered that contents of the FBAI all initially increased and subsequently decreased from the top to the bottom of the roots. The baicalin content of WXR was less than that of TST. On the contrary, the contents of baicalein, wogonin, and oroxylin A in WXR were up to about two times higher than that in TST. We also found that the 0 to 40 cm part of the S. baicalensis root possessed about 87% of the root biomass and about 92% of the contents of the active ingredients.
