Schizocapsa plantaginea Hance

Taccalonolide B is microtubule stabilizer isolated from Tacca plantaginea, with antitumor activity. Taccalonolide B is effective in vitro against cell lines that overexpress P-glycoprotein (Pgp) and multidrug-resistance protein (MRP7). Taccalonolide B inhibits growth of SK-OV-3 cells with an IC₅₀ of 208 nM.

Plantagiolide C is a withanolide found in Tacca plantaginea. Tacca plantaginea has analgesic, antipyretic and anti-inflammatory effects.

(3R,5R)-3,5-Dihydroxy-1,7-bis(3,4-dihydroxyphenyl)heptane 3-O-β-D-glucopyranoside is a diarylheptanol glycoside compound isolated from Tacca plantaginea. (3R,5R)-3,5-Dihydroxy-1,7-bis(3,4-dihydroxyphenyl)heptane 3-O-β-D-glucopyranoside significantly inhibit TNF-α-induced NF-κB transcriptional activity (IC₅₀ = 9.4 μM). (3R,5R)-3,5-Dihydroxy-1,7-bis(3,4-dihydroxyphenyl)heptane 3-O-β-D-glucopyranoside significantly activates PPAR transcriptional activity (EC₅₀ = 9.9 μM) and has a specific activating effect on PPAR β(δ) (EC₅₀ = 23.1 μM). (3R,5R)-3,5-Dihydroxy-1,7-bis(3,4-dihydroxyphenyl)heptane 3-O-β-D-glucopyranoside is non-toxic to cells at the tested concentration. (3R,5R)-3,5-Dihydroxy-1,7-bis(3,4-dihydroxyphenyl)heptane 3-O-β-D-glucopyranoside can be used for research on inflammatory conditions.

Chantriolide A is a withanolide glucoside that can be isolated from the whole plant of Tacca plantaginea.
