摘要：
The kaempferol derivative 3,7-di-O-methyl-4'-O-beta-[alpha rhamnosyl (1-->6)]-glucopyranoside (siparunoside) was isolated from the leaves of Sparurna apiosyce. Its structure was established by extensive NMR studies. The alkaloids reticuline and liriodenine were also isolated from the leaves along with the kaempferol derivative tiliroside. Benzylisoquinoline alkaloids were isolated from the wood (liriodenine) and wood bark (liriodenine, laurotetanine, N-methyl-laurotetanine, reticuline), together with a mixture of cis and tians-N-feruloyltyramines. 3,7,4'-tri-0-methylkaempferol was isolated from all organs.
