Abstract
| - A new triterpenoid saponin, boussingoside E (1),3-O-[β-d-glucuronopyranosyl]-20(29)-ene-30-norhederagenin 28-O-(β-d-glucopyranosyl) ester,along with quinoasaponin-9 (2) were isolatedas sodium/choline salts from the methanolic extracts of the tubers ofBoussingaultia baselloidesH. B. K. (syn.: Anredera baselloides Baill.). Theirstructures were established on the basis of1D and 2D NMR (DQFCOSY, HOHAHA, HSQC, HMBC, and ROESY spectra),FABMSexperiments, and hydrolysis.
