Chemical constituents of the leaves of Triumfetta semitriloba.

The new flavone glycoside 6-O-(6"-O-E-p-coumaroyl)-beta-D-galactoscutellarein (triumfettalarein, 1), along with indol-3-carboxylic acid (2), beta-sitosterol glycoside, and squalene were isolated from the methanol extract of leaves of Triumfetta semitriloba. The structure of the new isolate was established by spectral methods.
