The ethereal extract of AJUGA IVA (L.) S CHREB. roots, yielded 4 ecdysones. Three were proved to be cyasterone, makisterone A and ecdysterone, by using UV, IR, MS spectral methods and comparison with standard samples. Spectral data indicate that the fourth ecdysone is similar to cyasterone but having an additional hydroxy group in the side-chain. The chromatographic pattern of ecdysone content in roots, stems and leaves is presented as well as a rapid and simple Semiquantitative method for their estimation. The roots had the highest total content (0.381%).
獐牙菜属 AJUGA IVA (L.) S CHREB. 的乙醚提取物中分离出 4 种蜕皮激素。利用 UV、IR、MS 光谱法并与标准样品比较，证明其中 3 种为 20-羟基蜕皮酮、 马卡甾酮 A 和蜕皮甾酮。光谱数据表明，第 4 种蜕皮激素类似于 20-羟基蜕皮酮，但在侧链上有一个额外的羟基。文中还给出了根、茎和叶中蜕皮激素含量的色谱图，以及一种快速、简单的半定量估计方法。结果表明根中的总含量最高（0.381%）。
