objective(s):astrodaucus persicus, apiaceae, is used as vegetable or food additive in some parts of iran. the essential oils of different parts of astrodaucus persicus from kordestan province were analyzed for the first time and compared with other regions. in this study, antioxidant activities and total phenols determination of aerial parts essential oils and root fractions of a. persicus were...

In the last article on square-root palindromes [1], we investigated constant square-root palindromes (those in which all terms are the same) using a combination of programs, guesses, and deduction. In this article, we’ll take a different approach: solving continued fractions to get data from which to derive more information about square-root palindromes. In a previous article [2], we showed a m...

Pharmacological studies were done on the root bark of mulberry tree and pharmacological effects were compared with the clinical effects of "Sohakuhi" in Chinese medicine. n-Butanol- and water-soluble fractions of mulberry root had similar effects except for those on the cadiovascular system. Both fractions showed cathartic, analgesic, diuretic, antitussive, antiedema, sedative, anticonvulsant, ...

The repellence of Aristolochia aff. orbicularis root, a native of Xochipala, Guerrero, Mexico, to the corn borer Sitophilus zeamais (Coleoptera) was investigated. The essential oil was isolated from the aromatic root and its repellent effect was assessed. About 40 components of the oil were identified using gas chromatography-mass spectrometry and other spectroscopic methods. The repellence of ...

The root extract and fractions of Croton zambesicus were investigated for anticancer activity against HeLa cells, DNA interaction, immunomodulatory and antileishmanial activities. The GCMS analysis of the most active fraction against HeLa cell was carried. The root extract was found to exert significant anticancer activity with the hexane fraction exhibiting the most pronounced effect. The crud...

The polypeptide complement of enriched soybean (Glycine max [L.] Merr. cult. wells) root plasma membrane fractions was studied by two-dimensional gel electrophoresis. Good resolution was obtained when polypeptides were solubilized in sodium dodecyl sulfate and when butylated hydroxytoluene was included in the vesicle isolation and solubilization media. The pattern obtained on the two-dimensiona...

Algorithms for polynomial real root isolation are ubiquitous in computational real algebraic geometry but few lower bounds are known for their maximum computing time functions. One exception is the continued fractions method due to Vincent (1836) and recommended by Uspensky (1948). Collins and Akritas (1976) proved that the maximum computing time of the method is at least exponential in the len...

The root bark, stem bark and leaves of Terminalia macroptera were sequentially extracted with ethanol, 50% ethanol-water, and 50 °C and 100 °C water using an accelerated solvent extractor. Ten bioactive purified polysaccharide fractions were obtained from those crude extracts after anion exchange chromatography and gel filtration. The polysaccharides and their native extracts were characterized...
