Using various chromatographic methods, five new steroidal saponins named taccavietnamosides A-E (1-5) and three known, (24S,25R)-spirost-5-en-3β,24-diol 3-O-α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→3)]-β-d-glucopyranoside (6), (24S,25R)-spirost-5-en-3β,24-diol
A novel withanolide glucoside, plantagiolide I (1), a new withanolide glucoside, plantagiolide J (2), and six known compounds (3-8) were isolated from the whole plant of Tacca plantaginea. Their structures were determined by spectroscopic and chemical methods. Compound 3 significantly inhibited
In the screening search for NF-κB inhibitory and PPAR transactivational agents from medicinal plants, a methanol extract of the whole plant of Tacca plantaginea and its aqueous fraction showed the significant activities. Bioassay-guided fractionation combined with repeated chromatographic separation
