Steroidal sapogenins of sixteen liliaceae plants.

New Steroidal Glycosides from Rhizomes ofClintonia udensis

“…2) A literature survey concerning the secondary metabolites of C. udensis shows that it has been suggested to contain a such steroidal sapogenins as diosgenin and heloniogenin, 3,4) although no systematic chemical work has been carried out on the plant. The present investigation on the steroidal glycoside constituents of the rhizomes of C. udensis resulted in the isolation of a total of 10 steroidal glycosides (1-10), including three new spirostanol glycosides (6)(7)(8), a new furostanol glycoside (9), and a new cholestane glycoside (10).…”

The chemistry and biological activity of the Hyacinthaceae

“…Albuca setosa has also been used by traditional healers in the Nkonkobe municipality in South Africa for the treatment of diabetes. 327 As part of a study on the steroidal saponins of various monocot families, Okanishi et al 328 found Albuca nelsonii N.E.Br. to contain ruscogenin 565.…”

Liliaceae Juss.

“…Some recognize a broadly circumscribed taxon of approximately 280 genera and 4200 species (Utech 2002a), whereas others prefer a narrow circumscription (16 genera and about 640 species) and divide the family into as many as 28 small families on the basis of morphological and molecular phylogenetic analyses Culham 2007;Seberg 2007h;Bremer et al 2009; see Reveal and Pires [ 2002] for an overview Brazos rain lily lycorine, γ-lycorine Z. drummondii b evening-star rain lily, prairie lily Z. simpsonii stagger grass, windfl ower, zephyr fl ower galanthine Sources: Cook and Loudon (1952); Wildman (1960aWildman ( , 1968 ; Fuganti (1975); Martin (1987 In addition to its horticultural importance, the Liliaceae is also of considerable toxicologic importance. At least a dozen different sapogenins are represented in the family (Okanishi et al 1975). The toxicants present are likewise dissimilar.…”
