The genome of Ralstonia solanacearum CaRs_Mep, a race 4/biovar 3/phylotype I bacterium causing wilt in small cardamom and other Zingiberaceae plants, was sequenced. Analysis of the 5.7-Mb genome sequence will aid in better understanding of the genetic determinants of host range, host jump, survival, pathogenicity, and virulence of race 4 of R. solanacearum.

Curcuma longa L. (Zingiberaceae family) and its polyphenolic compound curcumin have been subjected to a variety of antimicrobial investigations due to extensive traditional uses and low side effects. Antimicrobial activities for curcumin and rhizome extract of C. longa against different bacteria, viruses, fungi, and parasites have been reported. The promising results for antimicrobial activity ...

Zerumbone 1 is an 11-membered cyclic sesquiterpene obtained from the rhizomes of Zingiber zerumbet SMITH (Zingiberaceae). In this study, we investigated the structure-activity relationship of 1, α-humulene (2), tetrahydrozerumbone stereoisomers (3-5), and tetrahydrozerumbone derivatives (6-9). The oxygen-containing functional groups and the configurations at C1 and C2 contributed to the spontan...

Four new Curcuma species ( Zingiberaceae ) from Thailand are described here. fimbriata , C. micrantha and spathulata belong to subg. Hitcheniopsis while globulifera belongs the nominal . Each is compared morphologically closest detailed descriptions, colour plates information on their distribution, ecology, phenology uses provided. A preliminary IUCN conservation assessment of each these propos...

Ethanolic extract of rhizomes of Curcuma aromatica (Zingiberaceae) was investigated for its antitussive effect on Sulfur dioxide induced cough model in mice. The extract exhibited significant antitussive activity in a dose dependant manner. The activity was compared with the prototype antitussive agent codeine phosphate. The ethanolic extract at the dose of lOOmg. 200mg and 400mg/kg body weight...
