“…A paper chromatographic method using photometric quantitation was reported for red and white squill glycosides (Wichtl and Fuchs, 1962). Thin-layer chromatographic systems have been reported by several groups (Gorlich, 1960(Gorlich, ,1965Elkiey et al, 1965Elkiey et al, ,1967Kraus et al 1969;Steinegger and Van der Walt, 1961). TLC and reversed-phase HPLC assays for red squill extracts, but not plant materials, have been reported (Binkert, 1979).…”

Scilliroside and other bufadienolide glycosides in red squill, Urginea marítima (L.) Baker, were identified by isolation, high-performance liquid chromatography and thin-layer chromatography. Scilliroside, the major toxic glycoside, occurs in all plant parts including leaves, flower stalk, scales, and especially the roots and core of this bulbous plant. Other scilla compounds detected include desacetylscilliroside, scillarén A, and the aglycon scillirosidin. A new glucosylscilliroside and a phenolic nonscilla glycoside were also isolated and partially characterized. Scilliroside content of bulbs is highest in late summer after a dormancy period and does not appear to change with age. The scilliroside content of seed-derived varieties differs substantially, indicating a genetic factor affecting toxicant levels in the individual seedling plants. Toxicity of the bulbs is due principally to their content of scilliroside. The 6-acetoxy group of scilliroside contributes substantially to this toxicity.

“…184 The bufadienolides scillaren A 224, scilliroside 430, proscillaridin A 223 and scillaren F 431 have also been isolated from C. maritima (reported as Scilla maritima and/or Urginia maritima). [185][186][187][188][189][190] Using HPLC, with proscillaridin A 223 as a reference, Tittel and Wagner showed the possible presence of bufadienolides in a plant identied as Scilla rubra L. (here considered synonymous with C. maritima). 191 Petrol extracts of bulbs of this species (as Scilla maritima and Urginia maritima) were found to contain fatty acids (lauric acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid and linolenic acid) and sterols (sitosterol, stigmasterol, campesterol and cholesterol).…”

The chemistry and biological activity of the Hyacinthaceae

2013

View full text Add to dashboard Cite

The Hyacinthaceae (sensu APGII), with approximately 900 species in about 70 genera, can be divided into three main subfamilies, the Hyacinthoideae, the Urgineoideae and the Ornithogaloideae, with a small fourth subfamily the Oziroëoideae, restricted to South America. The plants included in this family have long been used in traditional medicine for a wide range of medicinal applications. This, together with some significant toxicity to livestock has led to the chemical composition of many of the species being investigated. The compounds found are, for the most part, subfamily-restricted, with homoisoflavanones and spirocyclic nortriterpenoids characterising the Hyacinthoideae, bufadienolides characterising the Urgineoideae, and cardenolides and steroidal glycosides characterising the Ornithogaloideae. The phytochemical profiles of 38 genera of the Hyacinthaceae will be discussed as well as any biological activity associated with both crude extracts and compounds isolated. The Hyacinthaceae of southern Africa were last reviewed in 2000 (T. S. Pohl, N. R. Crouch and D. A. Mulholland, Curr. Org. Chem., 2000, 4, 1287-1324; ref. 1); the current contribution considers the family at a global level.

“…Thin-layer chromatographic patterns of extraneural gangliosides are complex and only serve as a guide to distinguish them from brain gangliosides (852). Scilla glycosides, separated by TLC, have been determined quantitatively by direct densitometry, fluorimetry, and UV transmission using Kieselgel G with fluorescein for TLC (243).…”
