Curcumin-free turmeric exhibits anti-inflammatory and anticancer activities: Identification of novel components of turmeric.
Turmeric, a dried powder derived from the rhizome of Curcuma longa, has been used for centuries in certain parts of the world and has been linked to numerous biological activities including antioxidant, anti-inflammatory, anticancer, antigrowth, anti-arthritic, anti-atherosclerotic, antidepressant, anti-aging, antidiabetic, antimicrobial, wound healing, and memory-enhancing activities. One component of turmeric is curcumin, which has been extensively studied, as indicated by more than 5600 citations, most of which have appeared within the past decade. Recent research has identified numerous chemical entities from turmeric other than curcumin. It is unclear whether all of the activities ascribed to turmeric are due to curcumin or whether other compounds in turmeric can manifest these activities uniquely, additively, or synergistically with curcumin. However, studies have indicated that turmeric oil, present in turmeric, can enhance the bioavailability of curcumin. Studies over the past decade have indicated that curcumin-free turmeric (CFT) components possess numerous biological activities including anti-inflammatory, anticancer, and antidiabetic activities. Elemene derived from turmeric is approved in China for the treatment of cancer. The current review focuses on the anticancer and anti-inflammatory activities exhibited by CFT and by some individual components of turmeric, including turmerin, turmerone, elemene, furanodiene, curdione, bisacurone, cyclocurcumin, calebin A, and germacrone.

Anti-H1N1 viral activity of three main active ingredients from zedoary oil.
Influenza virus is one of the most widespread infectious diseases in the world. It poses a serious public health threat to humans. With the emergence of drug-resistant virus strains, antiviral drugs are urgently needed to control virus transmission and disease progression. In this study, three main active substances-curcumol, curdione and germacrone-were isolated from the traditional Chinese medicine zedoary. They inhibited the replication of influenza A (H1N1) virus in a dose-dependent manner. After treatment with these compounds, the expression of viral protein and RNA synthesis were inhibited. In vivo, these compounds also reduced H1N1-induced lung damage and the load of virus in serum as well as whole blood cells. In a proteomic analysis, after treatment with germacrone, the expression of antiviral protein and the amount of intracellular virus were significantly reduced, further proving that germacrone can inhibit viral replication. Our experiments have shown that curcumol, curdione and germacrone can inhibit the replication of H1N1 virus; in particular, germacrone shows potential both in vitro and in vivo as a therapeutic drug.

Simultaneous quantification of curdione, furanodiene and germacrone in rabbit plasma using liquid chromatography-tandem mass spectrometry and its application to a pharmacokinetic study.
A simple, rapid and sensitive method was developed for the simultaneous quantification of curdione, furanodiene and germacrone in rabbit plasma using a LC-MS/MS analysis. The plasma sample preparation was a simple deproteinization by the addition of 3 vols of acetonitrile followed by centrifugation. The analytes and internal standard (IS) costunolide were separated on a Zorbax SB-C18 column (3.5 µm, 2.1 × 100 mm) with mobile phase of methanol-water (90:10, v/v) containing 0.1% formic acid at a flow rate of 0.3 mL/min with an operating temperature of 25°C. Detection was carried out by atmospheric pressure chemical ionization in positive ion selected reaction monitoring mode. Linear detection responses were obtained for the three test compounds ranging from 5 to 5000 ng/mL and the lower limits of quantitation were 5-10 ng/mL. The intra- and inter-day precisions (relative standard deviations) were within 9.4% for all analytes, while the deviation of assay accuracies was within ±10.0%. The average recoveries of analytes were >80.0%. All analytes were proved to be stable during all sample storage, preparation and analytical procedures. The method was successfully applied to the pharmacokinetic study of the three compounds after vaginal drug delivery of Baofukang suppository to rabbit.

Determination of five sesquiterpenoids in Xingnaojing injection by quantitative analysis of multiple components with a single marker.
A quantitative analysis of multiple components with a single-marker method was established for the simultaneous determination of five sesqutiterpenoids in Xingnaojing injection. This method was established with Xingnaojing injection determined by high-performance liquid chromatography coupled with diode array detection. The durability and system suitability of the established method were evaluated, and the reliable relative correction factors were obtained with curdione selected as an internal reference. The contents of the five components in all Xingnaojing injections were determined by external standard method and the contents of curcumenone, curcumenol, curzerenone, and germacrone were also calculated with the obtained relative correction factors. Then, relative error was investigated to estimate the difference of the two methods. As a result, the established new method possesses good adaptability, and there is no significant difference between the two methods, except for the content of curzerenone in eight samples. To put the established method into practice, the limits of quantitation of the established method of the five components were proposed and defined. Thus, the developed methodology can also be utilized to the quality evaluation of Xingnaojing injection, in spite of the difference found in the content of curzerenone between the external standard method and the newly established method.

[The fingerprint of Ezhu by GC-MS].
To study the fingerprint of Ezhu by GC-MS.. GC-MS analysis was performed for 18 samples of three species of Curcuma used as Ezhu. TIC profiles were evaluated by "Computer Aided Similarity Evaluation System" (MATLAB5.3 based, Ver. 1.240, developed by Research Center for Modernization of Chinese Medicine, Central South University). The characteristic peaks in chromatograms were identified by comparing mass data with literatures. Hierarchical clustering analysis was performed by SPSS based on the relative peak area (RPA) of identified peak to germacrone in 18 samples.. Resemblance values of 18 samples of Ezhu were pretty low. The mutual mode fingerprint plots of Ezhu were failed to develop. However, 18 samples were divided into two main clusters based on hierarchical clustering analysis, Curcuma wenyujin cluster and Curcuma phaeocaulis cluster, but the samples of Curcuma kwangsiensis were dispersive. Therefore, based on hierarchical clustering analysis, two mutual mode fingerprint plots of Curcuma wenyujin and Curcuma phaeocaulis were developed. But that of Curcuma kwangsiensis was failed because of low resemblance among samples.. The mutual mode fingerprint is the basis for quality control of Chinese materia medica from multi-origins. Development of GC-MS fingerprint of Ezhu was failed, which indicates that the chemical components in different species of herbs used as one Chinese materia medica may be significantly different. The relationship of chemical components and pharmacological activities should be further studied so as to elucidate the rationality of Chinese materia medica from multi-origins.
