CODEN: GWXXBX. CLASS: IC: A61K031-705. PRIORITY: JP 75-62263 24 May 1975. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) Amorphous steryl glucoside monopalmitates which are easily absorbable by the intestinal tract have increased hemostatic activity, and can be processed easily into pharmaceuticals were prepd. by mixing powd. cryst. steryl glucoside monopalmitate with .gtoreq.0.5 parts of fine particles of an org. or inorg. material and then either heating the mixt. at >110.degree. or dissolving it in a solvent and then distg. off the solvent. For example, cryst. steryl .beta.-D-glucoside monopalmitate extd. from soybeans was heated at 130.degree. for 15 min to give a semitransparent, glassy, amorphous product whose hemostatic activity was twice as great as that of the cryst. form. The cryst. drug (1g) was also mixed with 1g magnesium aluminum silicate particles and then heated at 135.degree. for 10 min to give a homogeneous disersion of the amorphous product in the silicate particles. The hemostatic activity of the dispersion was 4 times that of the cryst. form. .

On glycolipids in corn seeds

On glycolipids in corn seeds. Tanaka, Hiroyuki; Ohnishi, Masao; Fujino, Yasuhiko (Dep. Agric. Chem., Obihiro Univ. Agric. Vet. Med., Obihiro 080, Japan). Nippon Nogei Kagaku Kaishi, 58(1), 17-24 (Japanese) 1984. CODEN: NNKKAA. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Glycolipids of sweet corn were fractionated and analyzed. Corn contained 9.6% lipid, which consisted of neutral lipid 95, glycolipids 2, and phospholipid 3%. The main glycolipids were monoglycosylsterol, monoglycosylceramide, monoglycosyldiacylglycerol and diglycosyldiacylglycerol in decreasing order. Glycosylsterols consisted of acylmono-, mono-, di-, tri-, and tetraglycosylsterols. The principal classes of glycosylsterols were the 1st 2, the representative mol. species of which were 6'-palmitoyl-3-O-glucosylsitosterol [18749-71-8] and 3-O-glucosylsitosterol [474-58-8]. 87385-00-0 and 18749-71-8 are also in the experiment. The monoglycosylceramides were sepd. as sphingoglycolipids, the main mol. species being 1-O-glucosyl-N-2'-hydroxyarachidoyl-4,8-sphingadienine [89705-27-1] and 1-O-glucosyl-N-2'-hydroxylignoceroyl-4-hydroxy-8-sphingenine [87385-00-0]. Glycosylglycerides obtained were mono- and diglycosyldiacylglycerols. The principal mol. species were assumed to be 1-oleoyl-2-linoleoyl-o-O-galactosyl-sn-glycerol and 1-linoleoyl-2-linolenoyl-3-O-digalactosyl-sn-glycerol. The compn. of glycosylsterols and glycosylceramide in corn was similar to those of rice rather than those of wheat. .
