大叶冬青甙 I和苦丁冬青甙 K系分别从Ilex latifolia Thunb.和Ilex kudincha C. J. Tseng的叶子中分离得到的三萜皂甙.用化学和波谱方法，特别是2D NMR波谱技术，推定它们的结构分别为3-O-β-D-吡喃葡萄糖-(1→3)-α-L-吡喃阿拉伯糖-30(S)-3β,19α,23-trihydroxy- urs-12-en 28-oic acid 28-O-β-D-吡喃葡萄糖甙和3-O-［α-L-吡喃鼠李糖-(1→2)］-［β-D-吡喃葡萄糖-(1→2)-β-D-吡喃葡萄糖-(1→3)］-α-L-吡喃阿拉伯糖-3β,19α,20β-trihydroxyurs-12-en-28-oic acid 28-O-［α-L-吡喃鼠李糖-(1→2)］-β-D-吡喃葡萄糖甙，并对其NMR信号进行了全归属.

This paper discussed the structure elucidation of two saponins, Latifoloside I isolated from Ilex latifolia Thunb and Kudinoside K isolated from Ilex kudincha C. J. Tseng. On the basis of chemical and spectroscopic evidences, mainly modern 2D NMR technique, their structures were determined to be 3-O-β-D-glucopyranosyl-(1→3)-α-L-arabinopyranosyl-30(S)-3,19,23-trihydro-xyurs-12-en-28-oic acid 28-O-β-D-glucopyranoside and 3-O-［α-L-rhamnopyranosyl-(1→2)］-［β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl-(1→3)］-α-L-arabinopyranoyl-3β,19α,20β-trihydr-oxyurs-12-en-28-oic acid 28-O-［α-L-rhamnopyranosyl-(1→2)］-β-D-glucopyranoside，respectively.
