The phytochemical study of the roots of Phlomis umbrosa Turcz afforded a new phenylethanoid glycoside, 3-hydroxy-4-methoxy-β-phenylethoxy-O-[2,3-diacetyl-α-l-rhamnopyranosyl-(1 → 3)]-4-O-cis-feruloyl-[β-d-apiofuranosyl-(1 → 6)]-β-d-glucopyranoside (1), and two new 28-noroleanane-derived spirocyclic triterpenoids, phlomishexaol C (2) and phlomishexaol D (3). Their structures were elucidated on the basis of 1D and 2D NMR analyses, in combination with high-resolution MS experiment.
糙苏（Phlomis umbrosa Turcz）根的植物化学研究得到了一种新的苯乙醇苷，3-羟基-4-甲氧基-β-苯乙氧基-O-[2,3-二乙酰基-α-L-鼠李吡喃糖基-(1→3)]-4-O-顺式阿魏酰基-[β-D-芹菜呋喃糖基-(1→6)]-β-D-葡萄糖吡喃糖苷（1），以及两种新的28-降羽扇豆烷型螺环三萜类化合物，糙苏六醇C（2）和糙苏六醇D（3）。通过一维和二维核磁共振分析，并结合高分辨率质谱实验确定了它们的结构。
