Zingiberaceae family

Turmeric and Turmeric Oleoresin. Turmeric (Cl Natural Yellow 3, Cl No. 75300, EEC No. E 100) is the dried and ground rhizome or bulbous root of Curcuma longa, a perennial herb of the Zingiberaceae family native to southern Asia and cultivated in China, India, South America, and the East Indies. It is a yellow powder with a characteristic odor and a sharp taste. 

Turmeric is an aromatic spice obtained from the dried ground rhizomes of Curcuma longa L., a perennial shrub that belongs to genus Curcuma of the Zingiberaceae family. More than 100 species of curcuma were described but Curcuma longa L. is... 

In order to identify novel lead compounds with antiviral effects, methanol and aqueous extracts of some medicinal plants in the Zingiberaceae family were screened for inhibition of proteases from human immunodeficiency virus type 1 (HIV-1), hepatitis C virus (HCV) and human cytomegalovirus (HCMV). By bioassay-guided fractionation, eight fiavones were isolated from the black rhizomes of Kaempferia parviflora Wall, ex Baker. The most effective inhibitors, 5-hydroxy-7-methoxyfiavone and 5,7-dimethoxyflavone, inhibited HIV-1 protease, with an inhibitory concentration 50 (IC50) values of 19 0,M. Moreover, 5-hydroxy-3,7-dimethoxyflavone inhibited HCV protease and HCMV protease, with IC50 values of 190 and 250 pM, respectively. 

Turmeric is the rhizosomes of a plant which is a member of the Zingiberaceae family and native to southern and southeast Asia. The traditional name of this spice is Curcuma longa. 

The major pigment in Curcuma species (Zingiberaceae family) is the yellow phenolic diarylheptanoid curcumin (Jl). Curcumin and its analogs have potent antioxidant and antiinflammatory effects, cytotoxicity against tumor cells, and antitumor-promoting activity (96). The biologic effects and targets of curcumin, as well as its possible roles in cancer prevention and therapy, have been reviewed recently (97, 98). 

From plants belonging to the Zingiberaceae family several ptmgent compoimds (gingerones, shogaols, aparadols) were isolated (104, 105). The first pungent... 

In addition to curcumin, many other constituents in the Zingiberaceae family possess anti-inflammatory activity [15]. Some of these constituents, such as yakuchinones A and B isolated from Alpinia oxyphylla Miquel [16], Fig. (6), are diarylheptanoids and structurally similar to curcumin. 

Curcumin is the colourant principle of turmeric (Colour Index 75300, E 100) and tumeric oleoresin. The dried and ground powder from the rhizome or root of Curcuma longa of the Zingiberaceae family...
