This study was conducted to investigate the effects of Curcuma zedoaria and Zingiber zerumbet on non-specific immune responses of grouper (Epinephelus coioides). Fish were fed an experimental diet containing 0, 0.5, 1.0, 2.5 g/kg of C. zedoaria and Z. zerumbet mixed diets twice daily for two weeks. Non-specific immune parameters such as respiratory burst activity, reactive oxygen species, phago...

Zingiber zerumbet Smith is an important herb that contains bioactive phytomedicinal compound, zerumbone. To enhance cell growth and production of this useful compound, we investigated the growth conditions of cell suspension culture. Embryogenic callus generated from shoot bud was used to initiate cell suspension culture. The highest specific growth rate of cells was recorded when it was cultur...

Mode of reproduction is generally considered to have long-range evolutionary implications on population survival. Because sexual reproduction produces genetically diverse genotypes, this mode of reproduction is predicted to positively influence the success potential of offspring in evolutionary arms race with parasites (Red queen) whereas, without segregation and recombination, the obligate ase...

Zingiber zerumbet (L.) Smith, popularly known as shampoo ginger, is one of the most commonly used ingredients in Indo-Malaysian traditional medicines. The antioxidant and cytotoxic activities of the ethanolic extract of Z. zerumbet rhizome (ZZ) was investigated. 2,2-di(4-tert-octylphenyl)-1picryl-hydrazyl (DPPH) and hydroxyl radical scavenging assays showed significant radical scavenging activi...

Zingiber zerumbet (Z. zerumbet) is recognized for decades its usability as spice and condiment in food flavoring well having high medicinal properties. Up to date, there are limited literature on evaluation of the effects multiple variables details especially pilot-scale subcritical water extraction (SWE) Z. zerumbet. The aim this study implement fractional factorial design with five which temp...

BACKGROUND Zingiber zerumbet (L.) Smith belongs to the Zingiberaceae family that is widely distributed throughout the tropics, particularly in Southeast Asia. It is locally known as 'Lempoyang' and traditionally used to treat fever, constipation and to relieve pain. It is also known to possess antioxidant and anti-inflammatory activities. Based on these antioxidant and anti-inflammatory activit...

Nonsteroidal anti-inflammatory drugs (NSAIDs) have been widely used for the treatment of inflammation. However, despite their effectiveness, most NSAIDs cause various side effects that negatively affect the management of inflammation and, in part, pain. Thus, there is a need to search for new anti-inflammatory agents with few, or no, side effects. Natural products of plant, animal, or microorga...

Zingiber zerumbet (Zingiberaceae) is a wild, tropical medicinal herb that shows a high degree of resistance to diseases affecting cultivated ginger. Barley stripe mosaic virus (BSMV) silencing vectors containing an endogenous phytoene desaturase (PDS) gene fragment were agroinfiltrated into young leaves of Z. zerumbet under controlled growth conditions to effect virus-induced gene silencing (VI...
