Abstract A variety of wheat flours and ground oilseeds was subjected to continuous extraction for 6 h with each of 4 solvents (anhydrous diethyl ether, hexane, pentane, and petroleum ether). Hexane and diethyl ether were equally superior (P < 0.05) to the other 2 solvents In extracting crude oil from all-purpose flour and from ground peanuts, soybeans, cottonseeds, and canola seeds. Hexane yielded higher crude oil values (P < 0.05) than the other solvents in the case of ground safflower and sunflower seeds. Diethyl ether produced higher values (P < 0.05) from ground corn germ and bread flour. No differences (P < 0.05) were found among solvents when extracting whole wheat flour.

Abstract This rapid method for repurifying radiolabeled steroids from degraded products is based upon differential partitioning of intact and degraded molecules between aqueous-phase solution and anhydrous diethyl ether. Results compare favorably with those by liquid-chromatographic methods.

The essential oil was extracted by Soxhlet method with anhydrous diethyl ether from Ailanthus altissima Swingle (Sapindales: Simaroubaceae) bark, a traditional Chinese herbal plant, and its repellent and its fumigant activity was investigated against Lasioderma serricorne (Fabricius)(Coleoptera: Anobiidae) adults. A. altissima bark oil had extremely strong repellent activity against L. serricorne adults with the percentage repellency 93.7, 87.8 and 76.1% after 24, 48, and 72 h exposure, respectively. A. altissima bark oil also possessed high fumigant activity against L. serricorne adults with the corrected percentage mortality 100% at 8 µL/L air within 48 h exposure.

Platelet adhesion initiates platelet aggregation and is an important component of the hemostatic process. Since the development of a new form of collagen as a topical hemostatic agent is of both basic and clinical interest, an ultrastructural and hematologic study of the interaction of platelets with the microcrystalline collagen preparation was undertaken.In this study, whole blood anticoagulated with EDTA was used in order to inhibit aggregation and permit study of platelet adhesion to collagen as an isolated event. The microcrystalline collagen was prepared from bovine dermal corium; milling was with sharp blades. The preparation consists of partial hydrochloric acid amine collagen salts and retains much of the fibrillar morphology of native collagen.

ABSTRACT A radioimmunoassay was developed to measure the levels of oestrone and oestradiol in 0.5–1.0 ml of domestic fowl peripheral plasma. The oestrogens were extracted with diethyl ether, chromatographed on columns of Sephadex LH-20 and assayed with an antiserum prepared against oestradiol-17β-succinyl-bovine serum albumin using a 17 h incubation at 4°C. The specificity, sensitivity, precision and accuracy of the assays were satisfactory. Oestrogen concentrations were determined in the plasma of birds in various reproductive states. In laying hens the ranges of oestrone and oestradiol were 12–190 pg/ml and 29–327 pg/ml respectively. Levels in immature birds, in adult cockerels and in an ovariectomized hen were barely detectable. The mean concentrations of oestrone and oestradiol in the plasma of four non-laying hens (55 pg/ml and 72 pg/ml respectively) and one partially ovariectomized hen (71 pg/ml and 134 pg/ml respectively) were well within the range for laying hens. It is evident that the large, yolk-filled follicles are not the only source of oestrogens in the chicken ovary.
