alpha cyperone/cyperus

α-Cyperone, a sesquiterpene compound represents 25.23% of the total oil and is the most abundant compound in Cyperus rotundus oil. Endothelial cell protein C receptor (EPCR) is a main member in protein C (PC) anti-coagulation system. EPCR could be shed from cell surface, and is mediated by tumor

Ethnopharmacological relevance: Cyperus rotundus L. (Cyperaceae) is a widespread herbal in China and widely used in Traditional Chinese Medicine for multiple effects such as anti-arthritic, anti-genotoxic, anti-mutagenic, anti-bacterial

BACKGROUND Cyperus rotundus L. (Cyperaceae), commonly known as purple nutsedge or nut grass is one of the most invasive and endemic weeds in tropical, subtropical and temperate regions. This plant has been extensively used in traditional medicine for anti-arthritic, antidiarrheal and antiplatelet

α-Cyperone is the volatile oil component in Cyperus rotundus L. The previous reports had shown the inhibition of α-Cyperone on NF-κB signaling in LPS-stimulated RAW264.7 cells. However, it is still unclear whether α-Cyperone could suppress inflammatory response in acute lung injury (ALI) induced by

Cervical cancer is the fourth leading killer of female cancer patients worldwide. Each year more than half a million women are diagnosed with cervical cancer and the disease results in over 300, 000 deaths. α-Cyperone is known as the principal active ingredient in the Cyperus rotundus (Family:

Accumulating evidence has shown that activated microglia cause inflammatory immune response, which could lead to neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease. α-Cyperone, one of the main ingredients of Cyperus rotundus oil, has been reported to possess

BACKGROUND The rhizomes of Cyperus rotundus (Cyperaceae) have been used in Asian traditional medicine for the treatment of several inflammatory diseases. However, the anti-inflammatory effects of α-cyperone, a major active compound of Cyperus rotundus, are poorly understood. METHODS PGE2 and

α-Cyperone, extracted from Cyperus rotundus, has been reported to inhibit microglia-mediated neuroinflammation. Oxidative stress and apoptosis play crucial roles in the course of Parkinson's disease (PD). PD is a common neurodegenerative disease characterized by selective death of

OBJECTIVE To observe the analgesic effect and analysis the chemical components of essential oil (EOC) from fresh rhizome of Cyperus rotundus. METHODS Hydrodistillation method was used to extract EOC; Acetic acid induced mice stretching model was applied to evaluate the analgesic effect of EOC. Gas

The essential oil of Cyperus rotundus has multiple pharmacological activities. Therefore, the extraction with high yield and quality is very important for preparation of essential oil of C. rotundus. In this paper, three methods, namely hydrodistillation (HD), pressurized liquid extraction (PLE) and

Xiang-Qi-Tang (XQT) is a Chinese herbal formula containing Cyperus rotundus, Astragalus membranaceus and Andrographis paniculata. Alpha-Cyperone (CYP), astragaloside IV (AS-IV) and andrographolide (AND) are the three major active components in this formula. XQT may modulate the inflammatory or

Cyperus brevifolius andC. kyllingia are two common weeds in Hawaii. The underground parts, including the rhizomes and roots, contain allelopathic essential oils, which may contribute to the aggressive spread of these weeds in grasslands and lawns. Although morphologically similar,C. kyllingia

The essential oil compositions of the rhizomes of Cyperus conglomeratus (Cyperaceae) collected from Oman and the leaves of two Annonaceae plants, Desmos chinensis var. lawii and Cyathocalyx zeylanicus collected from India were studied by GC, GC-MS and 13C NMR spectroscopy. Twenty-six compounds,

Gas chromatography coupled with mass spectrometry (GC/MS), using both electron impact (EI) and chemical ionization (CI) detection modes on apolar and polar stationary phases, led to the determination of the volatile composition of the essential oil obtained from tubers of Cyperus rotundus
