Chemical investigation of methanol extract of the fruits of Diploclisia glaucescens (Menispermaceae) furnished two new bidesmosidic saponins 3-O-[beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranosyl]phytolaccagenic acid 28-O-beta-D-glucopyranosyl ester, 3-O-[alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl]phytolaccagenic acid 28-O-beta-D-glucopyranosyl ester, together with known 3-O-beta-D-glucopyranosylphytolaccagenic acid 28-O-beta-D-glucopyranosyl ester and 3-O-[alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl]serjanic acid 28-O-beta-D-glucopyranosyl ester. The last saponin is reported for the first time from the family Menispermaceae.
对青牛胆(防己科)果实的甲醇提取物进行化学研究,得到了两种新的双糖链皂苷:3 - O - [β - D - 吡喃葡萄糖基 - (1→3) - β - D - 吡喃葡萄糖基]商陆酸28 - O - β - D - 吡喃葡萄糖基酯、3 - O - [α - L - 鼠李吡喃糖基 - (1→2) - β - D - 吡喃葡萄糖基 - (1→2) - β - D - 吡喃葡萄糖基]商陆酸28 - O - β - D - 吡喃葡萄糖基酯,以及已知的3 - O - β - D - 吡喃葡萄糖基商陆酸28 - O - β - D - 吡喃葡萄糖基酯和3 - O - [α - L - 鼠李吡喃糖基 - (1→2) - β - D - 吡喃葡萄糖基 - (1→2) - β - D - 吡喃葡萄糖基]瑟江酸28 - O - β - D - 吡喃葡萄糖基酯。最后一种皂苷是首次从防己科植物中报道。
