Ardisiacrenoside I (1), a new triterpenoid pentasaccharide with an unusual glycosyl glycerol side chain, was isolated from Ardisia crenata together with five closely related triterpenoid saponins. Their structures were elucidated by a combination of mass spectrometry, IR, 1D, and 2D NMR spectroscopy. Their cytotoxic activities were evaluated against several different human tumor cell lines by the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) method.
从朱砂根中分离得到了一种新的具有不寻常糖基甘油侧链的三萜五糖——紫金牛苷I（1），以及五种密切相关的三萜皂苷。通过质谱、红外光谱、一维和二维核磁共振光谱相结合的方法阐明了它们的结构。采用3-[4,5-二甲基噻唑-2-基]-2,5-二苯基四氮唑溴盐（MTT）法对几种不同的人类肿瘤细胞系评估了它们的细胞毒性活性。
