“…The anomeric proton signal at d = 5.17 (d, J = 7.4 Hz) in the 1 H-NMR spectrum confirmed that the sugar residues were linked b-glycosidically, which agrees with the presence of an IR band at 890 cm ±1 [7], [8]. The b-configuration of the D-glucosyl groups was clearly evidenced by the presence of two anomeric peaks in the 13 C-NMR spectrum [9], [10]. The results suggested the basic structure 1 for the D-glucans of Cordyceps sinensis.…”

“…Date pits, a low-cost agricultural by-product, is a good precursor for production of activated carbon, which is the most popular adsorbent (Girgis and El-Hendawy 2002;Banat et al 2003). Some minor components, such as a water soluble galactomannan and an alkali soluble heteroxylan, were extracted from date seeds and then characterized (Ishrud et al 2001(Ishrud et al , 2003.…”

“…Phoenix dactylifera, belongs to tree palm family Arecaceae, consumed throughout the world and is an important part of the diet in the Middle East (Barh and Mazumdar, 2008). Phytochemical screening has revealed dried date pol--lens to contain sterols and other supplements such as vitamins and co---factors (Ishurd et al, 2003) and lack volatile substances (Hussein et al, 1998). Phytochemi--cal analyses of fruit flesh and seed of date revealed the presence of flavonoids (luteolin, methyl luteolin, quer--cetin, and methyl quercetin), flavanols (catechin, epi--catechin) (Al---shahib and Marshall, 2003;Bennett et al, 1966;Heftmann et al, 1965), free phenolic acids (pro--tocatechuic acid, vanillic acid, syringic acid, and feru--lic acid) (Mahran et al, 1976;Tabeta et al, 2002), tan--nins, glycosides, cardiac glycosides and steroids (cho--lesterol, stigmasterol, campesterol and α---sitosterol), essential amino acids (Biglari et al, 2008;Hong et al, 2006;Ziouti et al, 1996); and nine bound phenolic ac--ids (gallic acid, protocatechuic acid, p---hydroxybenzoic acid, vanillic acid, caffeic acid, syringic acid, p--coumaric acid, ferulic acid, and o---coumaric acid) (Hong et al, 2006;Hussein et al, 1998) respectively.…”
