The paper aims to isolate and identity flavonoids and saponins in old toonasinensis leaves to provide a the-oretical basis for further development of old toonasinensisleaves. Column chromatography and high performance liquid chromatography (HPLC) were used to separate and purify the substances in old toonasinensisleaves.Nuclear magnetic resonance (NMR) and infrared spectroscopy (IR) wereused for todeterminethe isolated substances. The old toonasinensisleaves of containrutin, epicatechin, quercetin, isoquercetin, guava glucoside, etc. The steroidal saponins and triterpenoidsaponins in toonasinensissaponins were identified by chromogenic reaction.Oldtoonasinensis leaves are rich in flavonoids and saponins, which have broad development prospects.
