Antitumor Constituents from Bulbs ofCrocosmia crocosmiiflora

Abstract
The water extract from the bulbs of Crocosmia crocosmiiflora (Nicholson) N. E. Br. (Iridaceae) and its pass-through fraction obtained by gel-filtration chromtography showed strong antitumor activity against Ehrlich carcinoma ascites and solid in Jcl-ICR mice when administered intraperitoneally. Some chemical studies revealed that the active principles in this plant were saponins consisting of medicagenic acid and polygalacic acid as the major sapogenins, and glucose, xylose, arabinose, rhamnose, and fucose as the sugar moieties.
