In order to find the anti-virus constituents of Alternanthera philoxeroides (Mart.) Griseb, the investigation was carried out. The paper reported the five triterpenoid saponins isolated from n-BuOH fraction: 3-O-beta-D-glucopyranosyl (1-->3)-O-[beta-D-glucopyranosyl-oleanolic acid]-28-O-beta-D-glucuronopyranoside (1), oleanolic acid-3-O-beta-D-glucuronopyranoside (calenduloside E, 2), oleanolic acid-3-O-beta-D-glucopyranosyl-28-Obeta-D-glucopyranosyl ester (chikusetsusaponin-IVa, 3), 3-O-(6'-O-butyl-beta-D-glucuronopyranosyl)-oleanolic acid-28-O-beta-D-glucopyranosyl ester (4) and hederagenin-3-O-beta-D-glucuronopyranoside (HN-sapoins K, 5). 1 is a new compound, saponins 4 and 5 were isolated from the plant for the first time.
为了寻找空心莲子草的抗病毒成分，开展了此项研究。该论文报道了从正丁醇部位分离得到的5种三萜皂苷：3 - O - β - D - 吡喃葡萄糖基(1→3) - O - [β - D - 吡喃葡萄糖基 - 齐墩果酸] - 28 - O - β - D - 吡喃葡萄糖醛酸苷(1)、齐墩果酸 - 3 - O - β - D - 吡喃葡萄糖醛酸苷（金盏花苷E，2）、齐墩果酸 - 3 - O - β - D - 吡喃葡萄糖基 - 28 - O - β - D - 吡喃葡萄糖基酯（竹节参皂苷 - IVa，3）、3 - O - (6'-O - 丁基 - β - D - 吡喃葡萄糖醛酸基) - 齐墩果酸 - 28 - O - β - D - 吡喃葡萄糖基酯(4)和常春藤皂苷元 - 3 - O - β - D - 吡喃葡萄糖醛酸苷（HN - 皂苷K，5）。1是一个新化合物，皂苷4和5首次从该植物中分离得到。
