Two undescribed compounds, 37-dihydroxy-24-methylenelanosta-8-ene-11-one () and neolignane deightonin () were isolated from the aerial parts of Croizat together with six known compounds, namely, kansenone (), euphorbol-7-one (), dehydrodiconiferyl diacetate (), marylaurencinol D (), scoparon (), and 3,4,3'-tri--methylellagic acid (). The structures of the isolated compounds were determined by HRESIMS, 1D (H, C JMOD) and 2D NMR (HSQC, HMBC, H-H COSY, NOESY) spectroscopic analysis, and by comparison of the assignments with literature data. The anti-herpes simplex virus type-2 activity of the isolated compounds were investigated by qRT-PCR assay on Vero cells after determining cytotoxic concentration 50% (CC). Compounds , , , and exhibited inhibitory effects with respective IC values of 7.05, 2.42, 11.73, and 0.032 µM. Scoparon () showed the strongest anti-HSV activity with a selectivity index of 10.93.
从克罗伊扎草的地上部分分离出两种未描述的化合物，3,7 - 二羟基 - 24 - 亚甲基羊毛甾 - 8 - 烯 - 11 - 酮（）和新木脂素代托宁（），以及六种已知化合物，即，蚕茧酮（）、大戟醇 - 7 - 酮（）、脱氢二松柏醇二乙酸酯（）、玛丽劳伦西诺醇D（）、滨蒿内酯（）和3,4,3'- 三 - O - 甲基鞣花酸（）。通过高分辨电喷雾电离质谱（HRESIMS）、一维（氢谱、碳谱、J 调制谱）和二维核磁共振（HSQC、HMBC、氢 - 氢相关谱、核Overhauser效应谱）光谱分析，并将化学位移数据与文献数据进行比较，确定了分离出的化合物的结构。在测定50%细胞毒性浓度（CC）后，通过对非洲绿猴肾细胞（Vero细胞）进行实时定量聚合酶链反应（qRT - PCR）测定，研究了分离出的化合物对2型单纯疱疹病毒的活性。化合物、、、表现出抑制作用，其各自的半数抑制浓度（IC）值分别为7.05、2.42、11.73和0.032 μM。滨蒿内酯（）显示出最强的抗单纯疱疹病毒活性，选择性指数为10.93。
