From roots of Taraxacum udum, two new and four known sesquiterpene lactones were isolated, together with five known phenolic compounds. The new compounds were characterized as 11beta, 13-dihydrotaraxinic acid and taraxinic acid 6-O-acetyl-beta-glucopyranosyl ester by spectroscopic methods, especially 1D and 2D NMR, and by comparison with structurally related compounds. The plant material was shown to be a good source of taraxinic acid derivatives.
从蒲公英属植物 udum 的根部，分离得到了两种新的和四种已知的倍半萜内酯，以及五种已知的酚类化合物。新化合物通过光谱方法，特别是 1D 和 2D NMR，并通过与结构相关的化合物进行比较，被鉴定为 11beta，13-二氢蒲公英酸和蒲公英酸 6-O-乙酰基-β-吡喃葡萄糖苷酯。该植物材料被证明是蒲公英酸衍生物的良好来源。
