Four novel triterpenoid saponins named asterbatanoside F, G, H and I were isolated from the roots of Aster batangensis and their structures elucidated as 3-O-beta-D-glucopyranosyl-23-O-acetyl-bayogenin-28-O-beta-D-glu cop yranosyl- (1-->6)-[alpha-L-rhamnopyranosyl-(1-->2)]-beta-D-glucopyranoside, 3-O-beta-D-glucopyranosyl-bayogenin-28-O-beta-D-glucopyranosyl-(1- ->6)-[alpha-f1p4amnopyranosyl-(1-->2)]-beta-D-glucopyranoside, 3-O-beta-D-glucopyranosyl- (1-->3)-beta-D-glucopyranosyl-bayogenin-28-O-beta-D-glucopyranosyl -(1-->6)-beta-D-glucopyranoside, and 3-O-beta-D-glucopyranosyl-(1-->3)-beta-D- glucopyranosyl-23-O-acetyl-bayogenin-28-O-beta-D-glucopyranosyl-(1 -->6)-beta-D- glucopyranoside by means of spectral data, especially NMR including COSY, HETCOR, COLOC, HOHAHA, ROESY and selective INEPT techniques, and chemical evidence.
从巴塘紫菀根部分离得到四种新的三萜皂苷，分别命名为紫菀皂苷F、G、H和I。通过光谱数据，特别是包括COSY、HETCOR、COLOC、HOHAHA、ROESY和选择性INEPT技术在内的核磁共振谱以及化学证据，确定它们的结构分别为3 - O - β - D - 吡喃葡萄糖基 - 23 - O - 乙酰基 - 波热吉宁 - 28 - O - β - D - 吡喃葡萄糖基 - (1→6)-[α - L - 吡喃鼠李糖基 - (1→2)] - β - D - 吡喃葡萄糖苷、3 - O - β - D - 吡喃葡萄糖基 - 波热吉宁 - 28 - O - β - D - 吡喃葡萄糖基 - (1→6)-[α - L - 吡喃鼠李糖基 - (1→2)] - β - D - 吡喃葡萄糖苷、3 - O - β - D - 吡喃葡萄糖基 - (1→3)-β - D - 吡喃葡萄糖基 - 波热吉宁 - 28 - O - β - D - 吡喃葡萄糖基 - (1→6)-β - D - 吡喃葡萄糖苷以及3 - O - β - D - 吡喃葡萄糖基 - (1→3)-β - D - 吡喃葡萄糖基 - 23 - O - 乙酰基 - 波热吉宁 - 28 - O - β - D - 吡喃葡萄糖基 - (1→6)-β - D - 吡喃葡萄糖苷。
