Abstract:In order to understand the chemical comstituents of Siraitia grosvenorii (Swingle) C. Jeffrey, nine compounds were isolated from the leaves of S. grosvenorii by using solvent fractionation and chromatographic technology. On the basis of spectral data, they were identified as: kaempferol-3,7-di-O-α-L-rahmnoside (1), kaempferol-3-O-α-L-rahmnoside (2), ferulic acid (3), 4'-O-methyldihydroquercetin (4), emodin (5), aloe-emodin (6), quercetin (7), kaempferol (8), kaempferol-7-O-α-L-rahmnoside (9). Among them, compounds 3 - 6 were isolated from the leaves of S. grosvenorii for the first time.
