Two triterpenoid glycosides have been isolated along with 10 known saponins from Bacopa monnieri. Structures of the compounds have been elucidated as 3-O-[beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranosyl] jujubogenin (1) and 3-O-[beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranosyl] pseudojujubogenin (2) by high resolution NMR spectral data and chemical correlations. Further, the chemical compositions of bacosides A and B have been delineated.
从水蓑衣中分离出了两种三萜糖苷以及10种已知的皂苷。通过高分辨率核磁共振光谱数据和化学关联，已阐明这些化合物的结构为3 - O - [β - D - 吡喃葡萄糖基 - (1→3) - β - D - 吡喃葡萄糖基] 酸枣仁皂苷元（1）和3 - O - [β - D - 吡喃葡萄糖基 - (1→3) - β - D - 吡喃葡萄糖基] 假酸枣仁皂苷元（2）。此外，还明确了印度醋栗皂苷A和B的化学组成。
