Cyperus rotundus L. has been widely distributed in China. In the exploration of Cyperi Rhizoma to pat attention on its geoherbalism is very necessary. The current index of quality control for Cyperi Rhizoma and Cyperus rotundus-volatile oil is the αCyperone contained in the Cyperus rotundus-volatile oil, different processing methods influence the content of their αCyperone. On the basis of the ...

In the present study antioxidant activity of the plant was assessed. For this purpose Cyperus rotundus was extracted by using different extraction solvents and evaluated for their antioxidant activity using different in vitro antioxidant assays. Total flavonoids contents in methanol extracts of Cyperus rotundus (8.15-18.25 mg CE/g of dry matter) were higher as compared to ethanol extracts (6.44...

Cataract is a clouding that developes in the crystalline lens of the eye or in its envelope, varying in degree from slight to complete opacity and obstructing the passage of light. Cataract was induced by incubating the chick lenses in 55mM glucose for 72 hours at 370C. Impact of hydroalcoholic extract of various concentrations was studied on the levels of trace elements, electrolytes, total pr...

Weed control efficacy of three herbicides recently registered for use in the South African Sugar Industry is discussed and the phytotoxic effects on sugarcane are presented. Destun, with or without atrazine, is a safe pre-emergence treatment which is useful for the control of Cyperus esculentus, grasses and broadleaf weeds, while some activity on Cyperus rotundus has also been recorded. Dual + ...

Two novel compounds, 1α-methoxy-3β-hydroxy-4α-(3′,4′-dihydroxyphenyl)-1, 2,3,4-tetrahydronaphthalin (1) and 1α,3β-dihydroxy-4α-(3′,4′-dihydroxyphenyl)-1,2,3,4-tetrahydronaphthalin (2), were isolated along with six known compounds 3-8 from the rhizomes of Cyperus rotundus. This paper reports the isolation and full spectroscopic characterization of these new compounds by NMR, UV, IR and MS data.

The study was designed to scientifically evaluate the effect of alchoholic extract of Cyperus rotundus rhizomes, a traditional medicinal herb, on isoproterenol-induce myocardial necrosis in rats model. The albino wistar rats were divided into five different groups with six animal in each group. Group I serves as a control group, group II were given isoproterenol (85 mg/kg s.c) for 2 days while ...

Outcome: Phytochemical investigation of Cyperus rotundus tubers resulted in isolation of four phytoconstituents characterized as n-tritriacontan-16-one (1), Lup-12, 20 (29)-dien-3β-ol-3-α-L-arabinofuranosyl-2'-octadec-9"-eonate (2), npentadecanyl-9-octadecenoate (3) and n-tetradecanyl-n-octadec-9, 12-dienoate (4). Only compound 2 showed antimicrobial activity. Lup-12, 20 (29)-dien-3β-ol3-α-L-ar...

Three Egyptian Cyperus species viz. Cyperus esculentus, C. rotundus, and C. papyrus that belong to Cyperaceae were used as food and medicines since ancient times. This study aimed to investigate the direct and indirect antioxidant properties of the selected species in two chemical assays (FRAP and DPPH) and a cell-based bioassay in hepa1c1c7 cells using t-butyl hydroperoxide (TBHP) as the induc...
