17-Isovalerate esters of ferrediol and sideritriol (compounds and ) and 17-(2-methylbutyrate) ferrediol (compound ), which have not been earlier described, were isolated along with five known -15-kaurene diterpenes (siderol, sideridiol, sideroxol, eubotriol, and -candicandiol), one -beyerene (flavovirol), and one phytosterol (β-sitosterol) from the aerial parts of subsp. (Boiss. & Heldr.) Baden that is a mountain tea species endemic to Northern Peloponnese in Greece. Compounds - exhibited weak antiproliferative activity against triple-negative MDA-MB-231 and Hs578T breast cancer cells. In MCF-7 breast cancer cells, compounds , , siderol, and sideridiol were equipotent to 5-fluorouracil (moderate antiproliferative activity).
从希腊伯罗奔尼撒半岛北部特有的山茶物种 亚种（Boiss. & Heldr.）Baden的地上部分分离出了此前未被描述过的铁二醇和三羟基铁三醇的17 - 异戊酸酯（化合物 和 ）以及17 -（2 - 甲基丁酸酯）铁二醇（化合物 ），同时还分离出了五种已知的 - 15 - 贝壳杉烯二萜（铁醇、铁二醇、铁氧醇、真三醇和 - 坎迪二醇）、一种 - 贝叶烯（黄维罗醇）和一种植物甾醇（β - 谷甾醇）。化合物 - 对三阴性MDA - MB - 231和Hs578T乳腺癌细胞表现出微弱的抗增殖活性。在MCF - 7乳腺癌细胞中，化合物 、 、铁醇和铁二醇的活性与5 - 氟尿嘧啶相当（中等抗增殖活性）。
