Three new triterpenoid saponins, named isoescins VIIa (1), VIa (2), and VIIIa (3), were isolated from the seeds of Aesculus turbinata and identified by spectroscopic analysis and chemical hydrolysis. Their structures were established as 21β-O-tigloyl-28-O-acetylprotoaescigenin 3β-O-[β-d-galactopyranosyl(1 → 2)][β-d-glucopyranosyl(1 → 4)]-β-d-glucopyranosiduronic acid (Isoescin VIIa, 1), 21β-O-(2-methylbutyryl)-28-O-acetylprotoaescigenin 3β-O-[β-d-glucopyranosyl(1 → 2)] [β-d-glucopyranosyl(1 → 4)]-β-d-glucopyranosiduronic acid (Isoescin VIa, 2), and 21β-O-angeloyl-28-O-acetylbarringtogenol C 3β-O-[β-d-glucopyranosyl(1 → 2)] [β-d-glucopyranosyl(1 → 4)]-β-d-glucopyranosiduronic acid (Isoescin VIIIa, 3).
