Continued chromatographic investigation of flowers led to the isolation of two sesquiterpenes, including one new, viridiflorol-10--β-quinovopyranoside-2--(3``-methyl-2``-pentenoate) (), along with a previously reported compound viridiflorol-10--β-fucopyranoside-2--(3-methyl-2-pentenoate) (). The new compound was tested for antiprotozoal activity against Amastigote/THP1 and and it showed IC values of 3.57 and 7.84 µg/mL, respectively, while compound exhibited no activity at the highest concentration tested 10 µg/mL.
对花朵进行持续的色谱研究，分离出了两种倍半萜，其中包括一种新的化合物，即绿花白千层醇-10-β-奎诺吡喃糖苷-2-(3``-甲基-2``-戊烯酸酯)，以及一种先前已报道的化合物绿花白千层醇-10-β-岩藻吡喃糖苷-2-(3-甲基-2-戊烯酸酯)。对新化合物进行了针对无鞭毛体/THP1和（此处原文似乎不完整）的抗原生动物活性测试，结果显示其IC值分别为3.57和7.84μg/mL，而化合物在测试的最高浓度10μg/mL时未表现出活性。
