curzerenone/curcuma

Two new sesquiterpenoids-13-hydroxycurzerenone (1) and 1-oxocurzerenone (2)-have been isolated from the rhizomes of Curcuma zedoaria, together with 13 known compounds (3-15). The structures of two new compounds were determined through spectroscopic and MS analyses. Among the isolated compounds,

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

Rhizomes of Curcuma phaeocaulis Valeton (Zingiberaceae) have traditionally been used for controlling inflammatory conditions. Numerous studies have aimed to isolate and characterize the bioactive constituents of C. phaeocaulis. It has been reported that its anti-inflammatory properties are a result

The essential oil extracted from rhizome and leaf of Curcuma angustifolia Roxb. (Zingiberaceae) was characterised by gas chromatography-mass spectrometry (GC-MS). The GC-MS analysis revealed the presence of 32 and 35 identified constituents, comprising 92.6% and 92% of total leaf and rhizome oil,

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 this research was to determine the chemical composition and insecticidal activity of the essential oil of Curcuma wenyujin Y.H. Chen et C. Ling rhizomes against the booklouse Liposcelis bostrychophila Badonnel and to isolate any insecticidal constituents from the essential oil. The

BACKGROUND Curcuma zedoaria Roscoe (Zingiberaceae), also known as white turmeric or zedoaria, has been used in Ayurveda and traditional Chinese medicine to treat various cancers, and it possesses several sesquiterpenoid compounds. OBJECTIVE This study aimed to evaluate the therapeutic effects of a

Volatile components of Curcuma sichuanensis X. X. Chen growing in Sichuan, China, were extracted by steam distillation and analyzed by using gas chromatography and gas chromatography-mass spectrometry. A total of 44 volatile essential oil components were identified in the extract of C. sichuanensis

Three new sesquiterpenoids (compounds 4, 5, and 26), along with 23 known sesquiterpenoids (compounds 1-3 and 6-25) and two diterpenoids (compounds 27 and 28), were obtained from Curcuma phaeocaulis, and their chemical structures were determined through nuclear magnetic resonance (NMR), circular

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

Bioassay-guided isolation of the active hexane fractions of Curcuma zedoaria led to the identification of five pure compounds, namely, curzerenone (1), neocurdione (2), curdione (3), alismol (4), and zederone (5) and a mixture of sterols, namely, campesterol (6), stigmasterol (7), and β -sitosterol

BACKGROUND Metabonomic analysis is an important molecular phenotyping method for characterising plant ecotypic variations; hence, it may become a powerful tool for quality control and discrimination of traditional Chinese medicine (TCM). OBJECTIVE To discriminate and assess the quality of Curcuma

The fresh rhizomes of Curcuma xanthorrhiza Roxb. were investigated for terpenoids and curcuminoids. Nine sesquiterpenoids, alpha-curcumene (1), arturmerone (2), xanthorrhizol (3), germacrone (4), beta-curcumene (6), beta-sesquiphellandrene (9), curzerenone (10), alpha-turmerone (11) and

Bioassay-guided fractionation of a hexane extract of the rhizomes of Curcuma xanthorrhiza Roxb. (Zingiberaceae) led to the isolation of three non-phenolic diarylheptanoids, identified mainly by high-field 1H-NMR as trans-trans-1,7-diphenyl-1,3-heptadien-4-one (alnustone),
