From the aerial parts of Lonicera japonica THUNB.(Caprifoliaceae), twelve triterpenoidalsaponins having oleanolic acid and hederagenin as aglycones, were isolated. The stnuctures of fournew saponins, 6, 9, 11 and 12, were established to be 3-O-α-L- arabinopyranosyl-28-O-[β-Dglucopyramosyl (1→ 6)-β-D-glucopyranosyl] oleanolic acid, 3-O- [α-L-rahmnopyranosyl (1→ 2)-α-L-arabinopyranosyl]-28-O-β-D-glucopyramosyl ...
