一种新的黄酮 C-糖苷，芹菜素 6-C-α-L-阿拉伯吡喃糖基-8-C-β-L-阿拉伯吡喃糖苷，与已知化合物芹菜素 6,8-二-C-α-L-阿拉伯吡喃糖苷、芹菜素一起从紫花地丁中分离出来。 6-C-α-L-阿拉伯吡喃糖基-8-C-β-D-吡喃葡萄糖苷（isoschaftoside）、芹菜素 6-C-β-D-吡喃葡萄糖基-8-C-α-L-吡喃葡萄糖苷（schaftoside）、芹菜素 6-C-β-D-吡喃葡萄糖基-8-C-β-L-阿拉伯吡喃糖苷(neoschaftoside)、芹菜素 6,8-二-C-β-D-吡喃葡萄糖苷 (vicenin-2)、芹菜素 6-C-α-L-阿拉伯吡喃糖基-8-C-β-D-吡喃木糖苷、芹菜素 6-C-β-D-吡喃木糖苷-8-C-α-L-阿拉伯吡喃糖苷、木犀草素6-C-β-D-吡喃葡萄糖苷（异荭草素）和木犀草素 6-C-α-L-阿拉伯吡喃糖基-8-C-β-D-吡喃葡萄糖苷（异卡利诺苷）。通过光谱方法确定结构，并为某些化合物提出了新的或修订的 H-1- 和 C-13-NMR 光谱分配。
A new flavone C-glycoside, apigenin 6-C-alpha-L-arabinopyranosyl-8-C-beta-L-arabinopyranoside, has been isolated from Viola yedoensis together with the known compounds, apigenin 6,8-di-C-alpha-L-arabinopyranoside, apigenin 6-C-alpha-L-arabinopyranosyl-8-C-beta-D-glucopyranoside (isoschaftoside), apigenin 6-C-beta-D-glucopyranosyl-8-C-alpha-L-arabinopyranoside (schaftoside), apigenin 6-C-beta-D-glucopyranosyl-8-C-beta-L-arabinopyranoside (neoschaftoside), apigenin 6,8-di-C-beta-D-glucopyranoside (vicenin-2), apigenin 6-C-alpha-L-arabinopyranosyl-8-C-beta-D-xylopyranoside, apigenin 6-C-beta-D-xylopyranosyl-8-C-alpha-L-arabinopyranoside, luteolin 6-C-beta-D-glucopyranoside (isoorientin) and luteolin 6-C-alpha-L-arabinopyranosyl-8-C-beta-D-glucopyranoside (isocarlinoside). The structures were determined by spectroscopic methods and new or revised H-1- and C-13-NMR spectral assignments are proposed for some compounds.
