Shizuoka Univ., Fac. Eng., Dep. Appl. Chem.: Hamamatsu, Japan. (English) 1981. CODEN: 50NWAS. DOCUMENT TYPE: Conference CA Section: 54 (Extractive Metallurgy) Cu was extd. from aq. NaClO4 by benzoylacetone [93-91-4] in benzene [71-43-2], and the extn. rate was controlled by the interfacial reaction. Surfactants, Na lauryl sulfate [151-21-3], octyltrimethyl ammonium bromide [2083-68-3], and Tween 80 [9005-65-6], strongly affected the Cu extn. rate.Except for chemicals metioned above, 151-21-3 and 2083-68-3 are also used. .

Intestinal absorption of dl-a-tocopherol from bile salts and polysorbate 80 micellar solutions in rat

Intestinal absorption of dl-a-tocopherol from bile salts and polysorbate 80 micellar solutions in rat.Some chemicals with cas registry numbers like 9005-65-6 and 1180-95-6 are also used.

DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) The intestinal absorption of dl-a-tocopherol (VE) [10191-41-0] from various micellar solns. was studied by in situ recirculating perfusion in rat small intestine. The perfused micellar solns. of VE were formed by Na taurocholate (STC) [145-42-6], Na taurodeoxycholate (STDC) [1180-95-6], or polysorbate 80 (PS-80) [9005-65-6]. The absorption ratio of VE was STC>STDC>PS-80 micellar solns. The addn. of egg lecithin (PC) to all micellar solns. caused a decrease of the absorption. The absorption ratio did not necessarily have a simple correlation with the VE solubilization in these micellar solns. The absorption ratio also correlated with the micellar size and with net water flux in the intestinal lumen. .
