The Zingiber genus, which includes the herbs known as gingers, commonly used in cooking, is well known for its medicinal properties, as described in the Indian pharmacopoeia. Different members of this genus, although somewhat similar in morphology, differ widely in their pharmacological and therapeutic properties. The most important species of this genus, with maximal therapeutic properties, is...

Chaeridiona mayuri n. sp. infesting ginger (Zingiber officinale Roscoe) and turmeric (Curcuma longa L.) in southern India is described and illustrated. Cheilocostus speciosus ( J. Koenig) C. D. Specht, Globba sessiliflora Sims and Zingiber zerumbet (L.) Smith are reported as additional host plants. Chaeridiona pseudometallica Basu is redescribed and illustrated. A key to the species of Indian C...

Zingiber zerumbet Sm., locally known to the Malay as "Lempoyang," is a perennial herb found in many tropical countries, including Malaysia. The rhizomes of Z. zerumbet, particularly, have been regularly used as food flavouring and appetizer in various Malays' cuisines while the rhizomes extracts have been used in Malay traditional medicine to treat various types of ailments (e.g., inflammatory-...

OBJECTIVE To investigate antimicrobial effects of ethanolic extract of Zingiber zerumbet (Z. zerumbet) (L.) Smith and its chloroform and petroleum ether soluble fractions against pathogenic bacteria and fungi. METHODS The fresh rhizomes of Zingiber zerumbet were extracted in cold with ethanol (4.0 L) after concentration. The crude ethanol extract was fractionated by petroleum ether and chloro...

An improved micropropagation protocol was developed for Zingiber moran and Z. zerumbet, two wild species of the genus Zingiber, found in Northeast India. The effects of growth regulators, sugar concentrations, and nutrients were tested on the rate of shoot initiation and multiplication. An increase in proliferation and multiplication occurred in modified Murashige and Skoog (MS) medium suppleme...

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...

Subcritical water extraction (SWE) is an alternative technique that implement water as a solvent. The objective of this work was to compare the efficiency of SWE in temperature range from 100ºC to 180ºC at extraction times ranging from 5 to 25 minutes with an ethanolic soxhlet extraction in terms of total phenolic content (TPC), total flavonoid content (TFC) and radical scavenging activity (RSA...

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...
