The leaves of Ilex paraguariensis have yielded three new saponins named matesaponins 2, 3, and 4 [1-3], which have been characterized by chemical and nmr methods as ursolic acid 3-O-[beta-D-glucopyranosyl-(1-->3)-[alpha-L-rhamnopyranosyl- (1-->2)]]-alpha-L-arabinopyranosyl]-(28-->1)-beta-D-glucopyranosyl ester, ursolic acid 3-O-[beta-D-glucopyranosyl-(1-->3)-alpha-L-arabinopyranosyl]-(28-- >1)- [beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl]ester, and ursolic acid 3-O-[beta-D-glucopyranosyl-(1-->3)-[alpha-L- rhamnopyranosyl-(1-->2)]]-alpha-L-arabinopyranosyl]-(28-->1)-[beta -D- glucopyranosyl-(1-->6)-beta-D-glucopyranosyl]ester, respectively.
巴拉圭冬青（Ilex paraguariensis）的叶子已产生了三种新的皂苷，分别命名为马黛皂苷2、3和4 [1 - 3]，通过化学和核磁共振方法鉴定，它们分别为乌索酸3 - O - [β - D - 吡喃葡萄糖基 - (1→3) - [α - L - 吡喃鼠李糖基 - (1→2)]] - α - L - 阿拉伯吡喃糖基] - (28→1) - β - D - 吡喃葡萄糖基酯、乌索酸3 - O - [β - D - 吡喃葡萄糖基 - (1→3) - α - L - 阿拉伯吡喃糖基] - (28→1) - [β - D - 吡喃葡萄糖基 - (1→6) - β - D - 吡喃葡萄糖基]酯以及乌索酸3 - O - [β - D - 吡喃葡萄糖基 - (1→3) - [α - L - 吡喃鼠李糖基 - (1→2)]] - α - L - 阿拉伯吡喃糖基] - (28→1) - [β - D - 吡喃葡萄糖基 - (1→6) - β - D - 吡喃葡萄糖基]酯。
