  • Title: Antitumor agents, 82. Cytotoxic sapogenols from Aesculus hippocastanum.
    Author: Konoshima T, Lee KH.
    Journal: J Nat Prod; 1986; 49(4):650-6. PubMed ID: 3783160.
    Abstract:
    Two cytotoxic sapogenols, the new hippocaesculin (1) and the known barringtogenol-C 21-angelate (2), were isolated from the acid hydrolysis product of a crude saponin fraction that was obtained from the fruits of Aesculus hippocastanum. The structures of 1 and 2 were determined from their chemical transformations and spectral data. Compound 1 is either 21-O-angeloyl, 22-O-tigloyl R1-barrigenol, or 21-O-tigloyl, 22-O-angeloyl R1-barrigenol.
