title: Two new flavonol glycosides from the leaves of Cleome chelidonii L.f.
abstract: From the leaves of Cleome chelidonii L.f., two new flavonol glycosides, named cleomesides A (1) and B (2), and four known compounds, quercetin 3-O-β-glucopyranosyl(1 → 2)-α-rhamnoside-7-O-α-rhamnoside (3), ethyl α-galactopyranoside (4), adenine (5) and glycerol monostearate (6), were isolated. The structures of all isolated compounds (1-6) were determined by NMR spectroscopy and mass spectrometry. The data of known compounds (3-6) were further compared with the reported data for these compounds.
