The phytochemical study of Euphrasia genargentea, a rare species only present in Sardinia, led to the identification of iridoid glucosides, i.e. aucubin, catalpol, mussaenosidic acid and melampyroside, which allowed chemotaxonomic considerations on the genus. On the basis of iridoid distribution in the genus, E. genargentea does not show any particular analogy with other Italian Euphrasia spp. This study is also important considering the severe risk of extinction of E. genargentea.
对仅存在于撒丁岛的稀有物种银灰小米草（Euphrasia genargentea）进行的植物化学研究，鉴定出了环烯醚萜苷，即桃叶珊瑚苷、梓醇、异去甲蟛蜞菊苷酸和黑麦草苷，这使得能够对该属进行化学分类学考量。基于该属中环烯醚萜的分布情况，银灰小米草与其他意大利小米草属物种没有任何特别的相似之处。鉴于银灰小米草面临的严重灭绝风险，这项研究也很重要。
