beta turmerone/ウコン属

Prostaglandins and nitric oxide produced by inducible cyclooygenase (COX-2) and nitric oxide synthase (iNOS), respectively, have been implicated as important mediators in the processes of inflammation and carcinogenesis. These potential COX-2 and iNOS inhibitors have been considered as

In the course of searching for biologically active sesquiterpenoids from Curcuma genus, two sesquiterpenoids were isolated from the rhizome of Curcuma zedoaria (Zingiberaceae). Their structures were identified as ar-turmerone (1) and beta-turmerone (2). The structure elucidation of compounds 1 and 2

Beta-turmerone and ar-turmerone, sesquiterpenoids isolated from the rhizome of Curcuma zedoaria, inhibited lipopolysaccharide (LPS)-induced prostaglandin E 2 production in cultured mouse macrophage cell RAW 264.7 in a dose-dependent manner (IC 50 = 7.3 microM for beta-turmerone; IC 50 = 24.0 microM

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

The sesquiterpenoids are one of major groups of antioxidants in Curcuma besides curcuminoids. However, the real substances contributing to the antioxidant activity are still unknown. In this paper, the antioxidant activity of sesquiterpenoids in four species and two essential oils from Curcuma genus

Extensive research on the mechanism of action and medicinal importance of curcumin obtained from turmeric (Curcuma longa) has unfolded its potential therapeutic value against many chronic ailments. Curcuma oil (C.oil), the highly lipophilic component from Curcuma longa has been documented for its

Ginger and turmeric are two food ingredients that are in high demand due to their flavor and positive effects on health. The biological properties of these spices are closely related to the aromatic compounds they contain. The chemical compositions of their essential oils and their in vitro

The need for a preventive agent against dementia led us to screen natural plant resources. Among the herbs and spices tested, turmeric, from rhizomes of Curcuma longa, showed high potency against β-secretase. The active principles were determined as α-turmerone, β-turmerone and ar-turmerone, with

Curcuma longa (Zingiberaceae) is a native plant of southern Asia and is cultivated extensively throughout the warmer parts of the world. Jianghuang and Yujin are rhizome and tuberous root of C. longa, respectively, which were traditionally used as two Chinese medicines. In this paper, pressurized

Curcuma longa (turmeric) has been used in Chinese traditional medicine and Ayurvedic medicine for many years. METHODS The leaf essential oil of C. longa from southern Nigeria was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). The essential oil was

Curcuma longa [Linn] (turmeric), of the Zingiberaceae family, has a great importance in the food, textile, and pharmaceutical industries. The aim of this work was to identify the best processing conditions to maximize the yields of essential oil and pigments, as well as their content of

The phytoconstituents of essential oil and ethanol oleoresin of fresh and dry rhizomes of turmeric (Curcuma longa Linn.) were analyzed by GC-MS. The major constituents were aromatic-turmerone (24.4%), alpha-turmerone (20.5%) and beta-turmerone (11.1%) in fresh rhizome and aromatic-turmerone (21.4%),

An expeditious strategy to resolve turmerone, the lipophilic anti-inflammatory principle of turmeric (Curcuma longa), into its individual bisabolane constituents (ar-, α-, and β-turmerones, 2-4, respectively) was developed. The comparative evaluation of these compounds against a series of

Fourteen novel terpene-conjugated curcuminoids, terpecurcumins J-W (1-14), have been isolated from the rhizomes of Curcuma longa L. Among them, terpecurcumins J-Q and V represent four unprecedented skeletons featuring an unusual core of hydrobenzannulated[6,6]-spiroketal (1 and 2),

The essential oil from Curcuma longa L. was analysed by GC/MS. The major components of the oil were ar-turmerone (33.2%), α -turmerone (23.5%) and β -turmerone (22.7%). The antifungal activities of the oil were studied with regard to Aspergillus flavus growth inhibition and altered morphology, as
