Ten triterpene saponins have been isolated from a MeOH extract of the leaves of Ilex oblonga. In their structures, six new triterpenoid saponins were named as oblonganosides H-M (2, 4, 5, and 8-10). All structures were elucidated on the basis of spectroscopic analysis. Among the triterpenoid
As a preliminary step in the phosphoproteome analysis of germinating seeds (0 and 24 h after seed imbibition) and early grown seedlings (216 h after seed imbibition) from a non-orthodox sp. Quercus ilex, a multiplex (SYPRO-Ruby and Pro-Q DPS) staining of high-resolution 2-DE gels was used. By using
A case-control study of oral and pharyngeal cancer involving interviews with 108 cases and 286 controls was carried out in the University Hospital of Montevideo, Uruguay. The study was restricted to males and cases afflicted with lip, salivary gland and nasopharyngeal cancer were excluded. Point
A case-control study of bladder cancer involving interviews with 111 incident cases and 222 controls was carried out in Montevideo, Uruguay. The analysis was conducted separately for each sex. Point estimates of relative risk associated with smoking variables, ingestion of infusions of the herb Ilex
The white flowers of N. suaveolens emit a complex bouquet of fragrance volatiles. The dominant compounds are benzenoids (e.g. methyl benzoate, methyl salicylate, benzyl benzoate and benzyl salicylate), monoterpenes (1,8-cineole, limonene, sabinene, E-beta-ocimene, beta-beta-myrcene, alpha- and
Details of the recently elucidated biosynthetic pathways of caffeine and related purine alkaloids are reviewed. The main caffeine biosynthetic pathway is a sequence consisting of xanthosine-->7-methylxanthosine-->7-methylxanthine-->theobromine-->caffeine. Genes encoding N-methyltransferases involved
Esophageal cancer has constituted a major public health problem in Uruguay, with age-adjusted death rates of 14.5 X 10(5) for males and of 3.8 X 10(5) for females. A case-control study was undertaken to ascertain the possible association of the local custom of drinking infusions of Ilex
BACKGROUND
Maté is a tealike beverage consumed habitually in South America and among South Americans throughout the world. It is brewed from the dried leaves and stemlets of the perennial tree Ilex paraguariensis (yerba maté), a species that belongs to the Aquifoliaceae family. Maté consumption has
Maté is a tea-like beverage consumed mainly in Argentina, Uruguay, Paraguay, southern Brazil and to a lesser degree in other areas of the world such as Germany, Syria, Lebanon and Northern Israel.

Part one of the paper discusses ethnobotanical, chemical and general pharmacological aspects of intoxicating snuff rituals in the western hemisphere. Four categories of ritual snuff ingredients arise from this multidisciplinary approach: It is well established that the plant contains one or more
To estimate the effects of consuming hot beverages, including mate (an infusion of the herb Ilex paraguayensis), tea, coffee and coffee with milk, and other food items on esophageal cancer risk, we analyzed data from 830 cases and 1,779 controls participating in a series of 5 hospital-based
