Herba Hederae terrestris

Hederae terrestris herba (ground ivy) (2) shows different and less concentrated triterpenoid zones in the R, range 0,15-0,2 and two additional weak grey-blue zones in the R, range 0.25-0.35 (ursolic and oleanolic acid derivatives). 

A prominent orange zone in the R, range of rutin found in Hederae terrestris herba (2) i,s probably due to luteolin-7-bioside, which is not extractable with 15% alcohol (see sample 4). Traces of yellow fluorescent hyjjeroside, isoquercetin and luteolin-7-0-glucoside are found in the R, range 0.6-0.7. The pattern of the blue fluorescent zones in the R range 0.6 up to the solvent front differs from that of Hedera helix (1,3,5). 

The Hederae folium trade sample 3 and commercial extrart 5 show low concentrations of saponin zones at Rf 0.2-0.3 and p-hederin at R, 0.75. The commercial extract 4 is prepared from Ptederae terrestris herba.
