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 ...

The TLR/IL-1R pathway is a critical signaling module that is misregulated in pathologies like inflammation and cancer. Extracts from turmeric (Curcuma longa L.) enriched in curcumin and carbonyls like turmerones have been shown to exert potent anti-inflammatory effects. The present study evaluated the anti-inflammatory activity, cytotoxic effect and the underlying mechanism of a novel chemicall...

Epidemiological evidence indicates that plant antioxidants activity can treat or help to prevent the development of various diseases. One species with great potential as an antioxidant is Curcuma longa. However, different extraction techniques influence isolated chemical compounds. This study investigated composition and two rhizome extracts C. longa: hydroethanolic, obtained by exhaustion (HEC...

The worldwide increase of multidrug resistance in both community- and health-care associated bacterial infections has impaired the current antimicrobial therapy, warranting the search for other alternatives. We aimed to find the in vitro antibacterial activity of ethanolic extracts of 16 different traditionally used medicinal plants of Nepal against 13 clinical and 2 reference bacterial species...

Cepedea longa Bezzenberger, 1904, collected from Fejervarya limnocharis (Amphibia, Anura, Ranidae) from Honghu Lake, Hubei Province, China in May-July 2016, is described at both light and transmission electron microscope levels. This is the first electron microscopic study of this species. Cepedea longa possesses a developed fibrillar skeletal system, composed of longitudinal fibrillar bands an...

Herbal remedies are increasingly being recognised in recent years as alternative medicine for a number of diseases including cancer. Curcuma longa L., commonly known as turmeric is used as a culinary spice in India and in many Asian countries has been attributed to lower incidences of gastrointestinal cancers. Curcumin, a secondary metabolite isolated from the rhizomes of this plant has been sh...

Pterygium is a relatively common eye disease that can display an aggressive clinical behaviour. To evaluate the in vitro effects of Curcuma longa on human pterygium-derived keratinocytes, specimens of pterygium from 20 patients undergoing pterygium surgical excision were collected. Pterygium explants were put into culture and derived keratinocytes were treated with an alcoholic extract of 1.3% ...

Choleretic drugs are used in some conditions e.g., fat maldigestion. Verapamil is a calcium channel blocker, which inhibits p-glycoprotein (P-gp) and may affect bile accumulation. Curcuma longa is traditionally used for treatment of maldigestion and as food additive. In this study, the effect of verapamil and Curcuma longa was compared on bile accumulation in gall bladder of mice. This simple a...

Snu-Yao Tsai et al., (2011) isolated the essential oils from the dried rhizomes of Curcuma aromatica salisb, Curcuma longa and Curcuma sichuanensis using simultaneous steam distillation and solvent extraction apparatus. Antioxidant studies were also carried out for these essential oils. Effectiveness for scavenging 1,1diphenyl-2-picrylhydrazyl radicals was found to be less in Curcuma aromatica ...

OBJECTIVES The aim of this study was to evaluate the effects of an oral supplementation with a Curcuma longa ethanol and aqueous extract on the susceptibility to oxidation of cellular and subcellular membranes affected in the atherosclerotic process, such as erythrocyte membranes and liver microsomes, in rabbits fed with a high-fat diet. METHODS Twenty-four male rabbits were randomly assigned...
