Disease of the kidney and of the urinary tract in De Medicina Methodica (Padua, 1611) of Prospero Alpini (1563-1616).

Aim: The study was devised to understand the contribution to nephrology ofDe Medicina Methodicaof Prospero Alpini published in 1511, at a time when the fame of the professor reached the azimuth.

Method: We have analyzed the contents of chapters devoted to nephrology in that book of Prospero Alpini and the novelties of his message.

Results: Prospero Alpini (1563-1616) taught at the University of Padua (1594-1616), at the same time of Galileo Galilei, Santorio Santorio, and Girolamo Fabrizi dAcquapendente, when measurements (pulse, temperature, perspiration) were introduced into medicine.

Diuretic plants in the Bible: ethnobotanical aspects.

Besides its religious importance, the Bible, because of its ancient origin represents a relevant witness of the way of life of the people mentioned in it. The Holy Scripture is also the first text revealing the utility of plants for man, as natural sources of food, wood, fibers, oils and medicinal herbs. In the last 60 years, several distinguished botanists have attempted to identify the scientific names of the plants cited in the Bible.

The diuretic use of Scilla from Dioscorides to the end of the 18th century.

Ancient texts contain an extremely large and readily accessible body of information on traditional medicine describing a range of plants and other substances that have been recently investigated systematically. However, prospecting for drugs from herbals raises problems with philology and plant identification. We combined our expertise to re-examine Squill an ancient medicinal plant which deserves modern scientific investigation.

Phytotoxins from the leaves of Ruta graveolens.

Bioassay-guided fractionation of the ethyl acetate extract of Ruta graveolens (common rue) leaves led to the isolation of the furanocoumarins 5-methoxypsoralen (5-MOP), 8-methoxypsoralen (8-MOP), and the quinolone alkaloid graveoline as phytotoxic constituents. Graveoline and 8-MOP substantially inhibited growth of Lactuca sativa (lettuce) seedlings and reduced chlorophyll content at 100 microM; this effect was not due to a direct effect on chlorophyll synthesis. Radical growth of L.

Natural fungicides from Ruta graveolens L. leaves, including a new quinolone alkaloid.

Bioassay-directed isolation of antifungal compounds from an ethyl acetate extract of Ruta graveolens leaves yielded two furanocoumarins, one quinoline alkaloid, and four quinolone alkaloids, including a novel compound, 1-methyl-2-[6'-(3' ',4' '-methylenedioxyphenyl)hexyl]-4-quinolone. The (1)H and (13)C NMR assignments of the new compound are reported. Antifungal activities of the isolated compounds, together with 7-hydroxycoumarin, 4-hydroxycoumarin, and 7-methoxycoumarin, which are known to occur in Rutaceae species, were evaluated by bioautography and microbioassay.

Josephus Andreas Jacobus Plenck - a forerunner of modern diuretic therapy.
