Overproduction of prostaglandins has been considered in mediation of inflammation and carcinogenic process. On this line, the inhibitors of prostaglandin biosynthetic enzyme cyclooxygenase (COX) have played a role of anti-inflammatory and cancer chemopreventive agents. In our continuous efforts to

Curcuma aromatica is a plant belonging to genus Curcuma of family Zingiberaceae and is widely used as supplements in Japan. Rhizomes of C. aromatica have curcumin as a major yellow pigment and curdione as a main ingredient of essential oils. In this study, we investigated the affect of C. aromatica

High-speed counter-current chromatography (HSCCC) was applied to isolate and purify bioactive compounds in the essential oil of the rhizomes of Curcuma wenyujin. Two sesquiterpenes germacrone and curdione were successfully isolated and purified using two-phase solvent system composed of petroleum

BACKGROUND Curdione, one of the major sesquiterpene compounds from Rhizoma Curcumae, has been shown to exhibit multiple bioactive properties. In this study, we investigated the anti-platelet aggregation and antithrombotic activities of curdione with different methods both in vitro and in vivo. The

The genus Curcuma is part of the Zingiberaceae family, and many Curcuma species have been used as traditional medicine and cosmetics in Thailand. To find new cosmeceutical ingredients, the in vitro anti-inflammatory, anti-oxidant, and cytotoxic activities of four Curcuma species

The chemical compositions of the essential oil of Curcuma zedoaria (Berg.) Rosc. were analyzed by gas chromatography-mass spectrometry (GC-MS) and showed a high content of epicurzerenone and curdione representing 46.6% and 13.7% of the total oil, respectively. The essential oil was evaluated for

Rhizoma Curcumae, the dry rhizomes derived from Curcuma aromatica Salisb., are a classical Chinese medicinal herb used to activate blood circulation, remove blood stasis and alleviate pain. Our previous study proved that curdione, a sesquiterpene compound isolated from the essential oil of Curcuma

The sesquiterpenoid curdione is one of the main bioactive components in the essential oil of Rhizoma Curcumae (Curcuma wenyujin, Curcuma phaeocaulis, and Curcuma kwangsiensis), which has been clinically used for the treatment of cancer in mainland China. Recently it was reported that natural

Curdione (1), a sesquiterpene with a germacrane skeleton from rhizomes of Curcuma wenyujin, has attracted attention due to its important pharmacological properties. Herein, we investigated the chemo-biotransformation of curdione (1) systematically using Aspergillus niger AS 3.739. Regio- and

OBJECTIVE To study the effective ingredients of Curcuma aromatica. METHODS Solvent extraction was used. The constituents were isolated with resin D-101 silica gel column and thin-layer chromatography, and the structures were elucidated by physico-chemical properties and spectral

OBJECTIVE To analyze the essential oil from the rhizome of Curcuma aromatica of different growth periods, and to provide the scientific reference for reasonable cultivation and quality control of this plant. METHODS The essential oil was extracted by hydrodistillation and analyzed with GC-MS. The

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

The chemical compositions of the essential oils from rhizomes of Curcuma aromatica cultivated in Japan and India were analyzed by GC and GC/MS. These oils were extremely different. The major constituents in both oils from Japanese samples were curdione, germacrone, 1,8-cineole,

The aim of the study was to investigate the sesquiterpene constituents from the rhizomes of Curcuma wenyujin Y. H. Chen et C. Ling. The isolation and purification of the constituents from the 50% EtOH extracts of the rhizomes were performed with repeated column chromatography over sillica gel and
