Four new triterpenoid saponins, ardisimamilloside C (1), 3-O-[alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->4)-[beta -D-glucopyranosyl-(1-->2)]-alpha-L-arabinopyranosyl]-3beta,16al pha,28,30-tetrahydroxy-olean-12-en, ardisimamilloside D (2), 3-O-¿alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->4)-[beta -D-glucopyranosyl-(1-->2)]-alpha-L-arabinopyranosyl]-3beta,15al pha,28,30-tetrahydroxy-olean-12-en, ardisimamilloside E (3), 3-O-[alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->4)-[beta -D-glucopyranosyl-(1-->2)]-alpha-L-arabinopyranosl]-13beta,2 8-epoxy-3beta,16alpha,29-oleananetriol, and ardisimamilloside F (4), 3-O-[alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->4)-[beta -D-glucopyranosyl-(1-->2)]-alpha-L-arabinopyranosyl]-3beta,16al pha-dihydroxy-13beta,28-epoxy-oleanan-30-oic acid were isolated from the roots of Ardisia mamillata Hance. Structure assignments were established on the basis of highresolution (HR)-FAB-MS, 1H-, 13C-, and two-dimensional (2D)-NMR spectra, and on the chemical evidence.
从走马胎（Ardisia mamillata Hance）的根中分离得到4个新的三萜皂苷，分别为矮地茶米罗皂苷C（1），即3 - O - [α - L - 鼠李吡喃糖基 - (1→2) - β - D - 葡萄糖吡喃糖基 - (1→4) - [β - D - 葡萄糖吡喃糖基 - (1→2)] - α - L - 阿拉伯吡喃糖基] - 3β,16α,28,30 - 四羟基 - 齐墩果 - 12 - 烯；矮地茶米罗皂苷D（2），即3 - O - [α - L - 鼠李吡喃糖基 - (1→2) - β - D - 葡萄糖吡喃糖基 - (1→4) - [β - D - 葡萄糖吡喃糖基 - (1→2)] - α - L - 阿拉伯吡喃糖基] - 3β,15α,28,30 - 四羟基 - 齐墩果 - 12 - 烯；矮地茶米罗皂苷E（3），即3 - O - [α - L - 鼠李吡喃糖基 - (1→2) - β - D - 葡萄糖吡喃糖基 - (1→4) - [β - D - 葡萄糖吡喃糖基 - (1→2)] - α - L - 阿拉伯吡喃糖基] - 13β,28 - 环氧 - 3β,16α,29 - 齐墩果烷三醇；以及矮地茶米罗皂苷F（4），即3 - O - [α - L - 鼠李吡喃糖基 - (1→2) - β - D - 葡萄糖吡喃糖基 - (1→4) - [β - D - 葡萄糖吡喃糖基 - (1→2)] - α - L - 阿拉伯吡喃糖基] - 3β,16α - 二羟基 - 13β,28 - 环氧 - 齐墩果烷 - 30 - 酸。通过高分辨（HR） - FAB - MS、1H - 、13C - 和二维（2D） - NMR光谱以及化学证据确定了其结构归属。
