Various extracts of Sarcostemma viminale were screened for central analgesic activity by hot plate test, peripheral analgesic activity by acetic acid-induced writhings, CNS depressant activity by pentobarbitone-induced sleep and locomotor activity testing methods and anthelmintic activity on the earthworms Pheretima posthuma . Results showed that petroleum ether and ethyl acetate extracts h...

Abstract Stachys lavandulifolia is from mint family and Labiatae species and grows in different parts of our country sporadically. The purpose of this study is to investigate the chemical properties of Stachys lavandulifolia Ethyl acetate extract. In this study, the Ethyl acetate extract was provided using maceration method. The extract then was defatted and solvent removal performed in a...

DGBA 1 Diethylene Glycol n-Butyl Ether Acetate (CAS# 124-17-4) (Synonyms: Butyl carbitol acetate; Butyl diglycol acetate; 2-(2-Butoxyethoxy)ethanol acetate; 2(2-Butoxyethoxy)ethyl acetate; Acetic acid 2-(2-butoxyethoxy)ethyl ester; Butoxyethoxyethyl acetate; Butyl carbitol acetate; Butyl diethylene glycol acetate; Diethyleneglycol monobutyl ether acetate; Diglycol monobutyl ether acetate; Ektas...

Stability and interface properties of cellulose acetate propionate (CAP) and cellulose acetate butyrate (CAB) films adsorbed from acetone or ethyl acetate onto Si wafers have been investigated by means of contact angle measurements and atomic force microscopy (AFM). Surface energy (gamma(S)(total)) values determined for CAP adsorbed from acetone are larger than those from ethyl acetate. In the ...

lactide was synthesized by reverse polymerization of low molecular weight poly(lactic acid) with two different molecular weights:1500 and 2500. two different lactide purification processes such as: recrystallization in ethyl acetate and washing the crude lactide with ether before recrystallization in ethyl acetate were evaluated. it has been demonstrated that increasing the molecular weight of ...

An experimental approach for the production of catalyst-free hyperpolarised ethanol solution in water via heterogeneous hydrogenation of vinyl acetate with parahydrogen and the subsequent hydrolysis of ethyl acetate was demonstrated. For an efficient hydrogenation, liquid vinyl acetate was transferred to the gas phase by parahydrogen bubbling and almost completely converted to ethyl acetate wit...

Chamaemelum nobile (Asteraceae) commonly known as 'Roman chamomile' is a medicinal plant used for numerous diseases in traditional medicine, although its anticancer activity is unknown. The present study was carried out to investigate the anticancer as well as apoptotic activity of ethyl acetate fraction of C. nobile on different cancerous cell lines. The cells were treated with varying concent...

Throat infections are common cause for visit to health care centres. This study is aimed at investigating the antibacterial efficacy of G. kola seeds against bacteria involved in throat infections. Twenty clinical and 4 typed bacterial isolates associated with throat infections were obtained. Extraction from G. kola seeds using ethanol, methanol, ethyl acetate, acetone, hot and cold water as ex...

Crystals of the title compound, C(22)H(29)NO(5)·C(4)H(8)O(2), {[systematic name: (2R,3R,5R,5aS,6R,8aR,9S)-(5Z)-5-[3-butyl-tetra-hydro-6-methyl-2,5-methano-4,3,8a-[1]propan-yl[3]yl-idene-furo[3,2-f][1,4]oxazepin-7(5H)-yl-idene]-4-meth-oxy-3-methyl-furan-2(5H)-one ethyl acetate solvate} were isolated from the root extracts of Stemona aphylla (Stemonaceae). The structure closely resembles those of...
