Two new steroidal bitter principles, taccolanolide O, P have been isolated from Tacca subflaellata and their structures were established by spectroscopic methods.
Two pentacyclic steroidal bitter principles, taccalonolide E and F, have been isolated from Tacca Plantaginea. Their structures were elucidated by spectroscopic methods.
