Abstract

Most saponins obtained from monocotyledonous plants are steroidal saponins and triterpenoid saponins are rarely found. The class of Iridaceae belongs to the monocotyledon. Family Gladioleae plants (Iridaceae) are widely cultivated as garden plants. In the course of studies on saponins in the Gladioleae, nineteen novel triterpenoid saponins were isolated from the corms of Crocosmia crocosmiiflora and C. masoniorum. Montbretia (C. crocosmiiflora N.E.Br.) belonging to the Gladioleae is cultivated on the garden. Several phytochemical investigations of C. crocosmiiflora have been undertaken. An antimicrobial naphthazarin derivative has been isolated by Masuda et al.1 Furthermore, it has been reported that the hot water extract of its corms shows antitumor activity and the antitumor active principle is a mixture of saponins.2
