 Curcum longa L. - syn. Curcuma domestica Valeton - Zingiberaceae \\ turmeric, Curcuma domestica Valeton, **Kurkuma**, Gelbwurz
-Native to  Southeast Asia; leaves very large, up to 1.20m or more long, including the petiole which is about as long as the blade, oblong-lanceolate, tapering at the base; flowers in autumnal spikes, 10-15cm long; peduncle 15cm or more, concealed by the sheathing petiole; flowers pale green, tinged with pink; rootstock large, ovoid, with sessile cylindric tubers orange-colored inside.

The dried rhizome with its cumine-like-woody-fruity odor and slightly bitter earthy flavor is used as spice.
-"The most important chemical components of turmeric are a group of compounds called curcuminoids, which include curcumin (diferuloylmethane), demethoxycurcumin, and bisdemethoxycurcumin. The best studied compound is curcumin, which constitutes 3.14% (on average) of powdered turmeric. In addition there are other important volatile oils such as turmerone, atlantone, and zingiberene. Some general constituents are sugars, proteins, and resins." [[http://en.wikipedia.org/wiki/Curcuma_longa]] \\
+"When not used fresh, the rhizomes are boiled for about 30-45 minutes and then dried in hot ovens, after which they are ground into a deep-orange-yellow powder commonly used as a spice in Bangladeshi cuisine, Indian cuisine, Pakistani cuisine and curries, for dyeing, and to impart color to mustard condiments. ... The most important chemical components of turmeric are a group of compounds called curcuminoids, which include [[https://en.wikipedia.org/wiki/Curcumin|curcumin]] (diferuloylmethane), demethoxycurcumin, and bisdemethoxycurcumin."

 The rhizome oil of C. longa have been found to contain ar-turmerone (51.8%) and ar-turmerol (11.9%) as main constituents. \\

 "A methanol extract of the dried powdered turmeric rhizome and curcumin were tested against 19 strains of H. pylori, including 5 cagA+ strains. Both the methanol extract and curcumin inhibited the growth of all strains of H. pylori in vitro with a minimum inhibitory concentration range of 6.25-50 micrograms/ml. These data demonstrate that curcumin inhibits the growth of H. pylori cagA+ strains in vitro, and this may be one of the mechanisms by which curcumin exerts its chemopreventative effects." \\
