The Curcuma zedoaria rhizome has been used traditionally to treat gastrointestinal diseases as an aromatic stomachic drug, and this is currently used to treat alcohol-induced loss of appetite and nausea in Japan. We examined the effects of various fractions and isolated compounds on alcohol-induced
Curcuma zedoaria also known as Temu putih is traditionally used in food preparations and treatment of various ailments including cancer. The cytotoxic activity of hexane, dichloromethane, ethyl acetate, methanol, and the methanol-soxhlet extracts of Curcuma zedoaria rhizomes was tested on two human
From the methanolic extract of the rhizome of Curcuma zedoaria, we isolated anti-inflammatory sesquiterpene furanodiene (1) and furanodienone (2) along with new sesquiterpene compound 3 and known eight sesquiterpenes, zederone (4), curzerenone (5), curzeone (6), germacrone (7), 13-hydroxygermacrone
OBJECTIVE
To study the chemical constituents of the stem and leaves from Curcuma wenyujin.
METHODS
The compounds were isolated by silica gel column chromatography in associating with Sephadex LH -20 chromatography. While their structures were identified on the basis of spectroscopic
Some Curcuma species are widely used as herbal medicines. Sesquiterpenes are their important bioactive compounds and their quantitative analysis is generally accomplished by gas chromatography (GC) or high performance liquid chromatography (HPLC), but the instability and high cost of some
Simple gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC) methods were developed for quantifying eight volatile compounds and 10 sesquiterpenoids, respectively. GC-MS analysis was performed on an HP-5MS capillary column (30 m×0.25 mm i.d.) coated with 0.25
From the dried rhizomes of Curcuma comosa cultivating in Thailand, 26 known sesquiterpenes were isolated: zederone, zederone epoxide, furanodienone, isofuranodienone, 1(10)Z,4Z-furanodiene-6-one, glechomanolide, dehydrocurdione, neocurdione, curdione, 7 alpha-hydroxyneocurdione, 7
Hepatoprotective sesquiterpenes were isolated from the aqueous acetone extract of Zedoariae Rhizoma, the rhizome of Curcuma zedoaria ROSCOE (Zingiberaceae). Principal sesquiterpenes, furanodiene, germacrone, curdione, neocurdione, curcumenol, isocurcumenol, aerugidiol, zedoarondiol, and curcumenone
A preparative gas chromatography (pGC) method was developed for the separation of volatile components from the methanol extract of Curcuma rhizome. The compounds were separated on a stainless steel column packed with 10% OV-101 (3 m × 6 mm, i.d.), and then, the effluent was split into two gas flows.
A high-performance liquid chromatography coupled with diode array detection (HPLC-DAD) and pressurized liquid extraction was developed for simultaneous quantitative determination of 11 characteristic compounds, including curcumenone, curcumenol, neocurdione, curdione, isocurcumenol, furanodienone,
We wished to search for the compounds contributing to the anti-inflammatory effects of the water extract of Curcuma longa (WEC). WEC was fractioned and the fractions were evaluated with regard to their inhibitory effect on the production of nitric oxide (NO) from the macrophage cell line stimulated
GC-MS is a powerful tool for analysis of volatile oil, and resolutions of analytes were exclusively used as marker for optimization of the conditions. However, volatile oil usually contains heat labile components which may degrade and result in wrong results during GC analysis. In present study,
Rhizomes of Curcuma caesia are traditionally used to treat cancer in India. The aim is to isolate chemical constituents from C. caesia rhizomes through bioassay-guided fractionation. The extract, hexanes and chloroform fractions showed effect on MCF-7 and MDA-MB-231cells in cell
