摘要：

A new biflavanone has been isolated from the stem bark of Garcinia mannii (Guttiferae) and identified as I-3′-II-3,3′-I-4′-II-4′-I-5-II-5-I-7-II-7-nonahydroxy-I-3-II-8-biflavanone. Structural assignments for this compound, which has been named manniflavanone, were made on the basis of spectral studies and simple degradation. The complex xanthone derivative xanthochymol has also been isolated. © 1979.
