黄芩作为一种重要的草本植物，地理分布广泛，在世界各地广泛使用。在中药市场上，黄芩主要分为“苦芩”（WXR）和“调芩”（TST）两个主要类型。而且，TST还根据根的直径分为不同的等级。为探讨5种生物活性成分(FBAI)含量的分布规律，以六年生黄芩为原料，分析其生长特性以及不同类型和根部直径的品质差异。在整个根中，我们发现从根的顶部到底部，FBAI 的含量都是先增加然后减少。 WXR的黄芩苷含量低于TST。相反，WXR中黄芩素、汉黄芩素和木木素A的含量比TST高出约两倍。我们还发现，黄芩根0~40cm部分拥有约87%的根生物量和约92%的活性成分含量。
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.
