TERNIFLORIN, A NEW FLAVONOID COMPOUND IN FLOWERS OF CLEMATIS TERNIFLORA A.P. DE CANDOLLE VAR. ROBUSTA TAMURA.

The presence of a new flavonoid glycoside, terniflorin, C30H26O12·H2O, m. p. 266∼267°(decomp.), is demonstrated in flowers of Clematis terniflora A. P. de CANDOLLE var. robusta TAMURA (Ranunculaceae). On basis of composition, hydrolysis, and ultraviolet and infrared spectra, terniflorin is identified as apigenin-7-(p-coumaroyl)-β-D-glucoside.
