A new benzofuran derivative from Flemingia philippinensis Merr. et Rolfe.
A new prenylated benzofuran derivative, named flemiphilippinone A, was isolated together with ten known flavonoids from the roots of Flemingia philippinensis. Flemiphilippinone A was identified as (2S,3aS)-5-(1-hydroxy-3-(4-methoxyphenyl)-propylidene)-2-(2-hydroxypropan-2-yl)-3a,7-bis(3-methylbut-2-en-1-yl)tetrahydrobenzofuran-4,6(2H,5H)-dione, and its structure was established by a combination...
متن کاملOxidized multi walled carbon nanotubes for improving the electrocatalytic activity of a benzofuran derivative modified electrode
In the present paper, the use of a novel carbon paste electrode modified by 7,8-dihydroxy-3,3,6-trimethyl-3,4-dihydrodibenzo[b,d]furan-1(2H)-one (DTD) and oxidized multi-walled carbon nanotubes (OCNTs) is described for determination of levodopa (LD), acetaminophen (AC) and tryptophan (Trp) by a simple and rapid method. At first, the electrochemical behavior of DTD is studied, then, the mediated...

متن کاملThe Structure of a New Metabolic Derivative of Quinine*
The isolation and crystallization of a product obtained by the in vitro action of rabbit liver on quinine (I) have recently been described by Kelsey, Geiling, Oldham, and Dearborn (1). The work reported here was undertaken with the object of obtaining information, as rapidly as possible, as to the possible structure of this product, which might prove useful in other malarial investigations. Thu...
متن کاملsolution of security constrained unit commitment problem by a new multi-objective optimization method
چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...
