The Pharmacological actions of Plants of the Genera Cotyledon and Crassula, N.O. Crassulaceae, with other Papers

The disease known as "Krimpsiekte" (Nenta, Kraamsiekte, cerebrospinal meningitis, Cotyledonosis) has been recognised in South Africa for ma.ny years. It appears in arid parts of the Cape Province, and affects animals which have ingested certain members of the genus Cotyledon (N.O. Crassulaceae)

Caffeine Content of Tea and Coffee

The caffeine content of teas and coffees blended and marketed in South Africa was estimated. Samples of tea contain caffeine varying from 2,723% to 4,1%. Coffee 'mixtures' contain 1,23 - 1,66%, freshly ground roast coffee beans 0,8 - 1,8% and one 'instant coffee' 'made from 100% coffee', 4,38%'S. Afr. Med. J., 48, 510 (1974

The chemistry and biological activity of the Hyacinthaceae

Covering: 1914 to 2012The 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; ); the current contribution considers the family at a global level
