It has 40 genera of herbs, shrubs, and trees.Glycosides: Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed. (From Dorland, 28th ed; From Miall's Dictionary of Chemistry, 5th ed)Dioscoreaceae: The yam plant family, of the order Liliales, has thick roots or tubers and net-veined, heart-shaped leaves that sometimes are lobed.Nelumbo: A plant genus of the family NELUMBONACEAE.

Members contain benzoquinones, steroidal saponin, and ribosome-inactivating proteins.Liliaceae: A monocot family within the order Liliales. This family is divided by some botanists into other families such as Convallariaceae, Hyacinthaceae and Amaryllidaceae. Amaryllidaceae, which have inferior ovaries, includes CRINUM; GALANTHUS; LYCORIS; and NARCISSUS and are known for AMARYLLIDACEAE ALKALOIDS.Picrorhiza: A plant genus of the family Plantaginaceae. Members contain scrosides (CINNAMATES) and phenylethanoid glycoside.

The flowers have 3 green sepals, 3 yellow and white petals, 6 stamens, and several pistils. Members contain TRITERPENES and SESQUITERPENES. Alisma is a component of tokishakuyakusan. Some species in this genus are called water plantain which is also a common name for other ALISMATACEAE plants.Saponins: A type of glycoside widely distributed in plants. Each consists of a sapogenin as the aglycone moiety, and a sugar. The sapogenin may be a steroid or a triterpene and the sugar may be glucose, galactose, a pentose, or a methylpentose.Ligusticum: A plant genus of the family APIACEAE.Convallaria: A plant genus of the family LILIACEAE that contains CARDIAC GLYCOSIDES.
