By following the antihemorrhagic activity according to Tajima's method, two antihemorrhagic principles, a new flavonol glucoside (1) and an unknown compound (2), were isolated from the dried pollen of Typha lactifolia L., which is one of the most important herbs for treatment of stagnant blood and bloody stools in traditional Chinese medicine.The structure of 1 was established as isorhamnetin 3-rutinoside-7-rhamnoside (3-[6-O-(6-deoxy-α-L-mannopyranosyl)-β-D-glucopyranosyl] Oxy-5-hydroxy-7-[β-L-mannopyranosyl] oxy -2-(4-hydroxy-3 -methoxyphenyl)-4H-1-benzopyran-4-one), based on chemical transformations and spectral data.
