Certain abortifacients have drastic purgative effects or are gastrointestinal irritants that can produce reflex uterine contraction. Many volatile oils, such as oil of tansy Tanacetum vulgare), and saponin glycosides, such as those found in bethroot Trillium erectum), act in this manner. 

The structures of the hepta-O-acetylsucroses produced by deacetylation of octa-O-acetylsucrose on aluminium oxide impregnated with potassium carbonate have been determined. Four principal hepta-O-acetyl components were obtained in 34% total yield, all having a hydroxy group free in the fructose moiety (ratios of free hydroxy groups, 4 (43%) 1 (23%), 3 (19%) and 6 (15%)) Likewise two hexacetates (3 4 and 1, 3 -dihydroxy compounds) were isolated in 42% yield, others only being present in trace amounts. The tetra-acetyl disaccharide 2,3>4-tri-0-acetyl-ik-L-rhamnopyranosyl-(l-2)-4-0-acetyl- <-L-arabino-pyranose has been isolated as a steroidal glycoside from the plant Trillium 10 -----------------------------------------------------...
