A sample of the flower-petals of Thespasia populnea is found to contain populnin (0·33%), populnetin (0·07%) and herbacetin (mostly as its glucoside, 0·03%). The proportions vary with different samples depending on seasonal and other factors. Besides these three yellow pigments, a colourless phenolic compound called populneol is also present (0·16%). Populnetin seems to be a new tetrahydroxy flavone and populnin is its monoglucoside.
