TL;DR: Es war wahrscheinl ich, dass die in der Milch der stillenden Mii t te r v o r k o m m e n d e n Ant ik6rper auch im Blut se rum nachweisbar sind.
Abstract: nehmen, dass die Ergebnisse der in der Tabel le zusammengeste l l ten Milchproben je nach der Zei t der E n t n a h m e anders ausgefaUen w~ren. Es war wahrscheinl ich, dass die in der Milch der stillenden Mii t te r v o r k o m m e n d e n Ant ik6rper auch im Blut se rum nachweisbar sind.

TL;DR: The results of antioxidant activity estimation by electron spin resonance (ESR) method showed that psoralidin was the most active antioxidant with an IC50 value of 44.7microM, which is the first report on simultaneous of eight compounds from P. corylifolia by HSCCC.

TL;DR: In this article, eleven cupric compounds were screened to determine whether a different cupric anion might give greater and more uniform charring responses with lipid classes on TLC plates than cupric acetate.
Abstract: Eleven cupric compounds were screened to determine whether a different cupric anion might give greater and more uniform charring responses with lipid classes on TLC plates than cupric acetate. A procedure was developed which used 10% CuSO4 in 8% H3PO4 as a charring reagent. Improved reproducibility of charring was obtained by temperature-programmed heating of the thin layer plates from 30 to 180°C at 10 degrees per minute in the oven of a commercial gas-liquid chromatograph.

TL;DR: The isolation and identification of cholesterol α-oxide, coprostanol, β-sitosterol, cholest-4-en-3-one and cholesta-4, 6-dien- 3-one from human serum are reported.
Abstract: The isolation and identification of cholesterol α-oxide, coprostanol, β-sitosterol, cholest-4-en-3-one and cholesta-4, 6-dien-3-one from human serum are reported. Compounds were isolated by thin layer chromatography and were identified by gas liquid chromatography and gas chromatography-mass spectrometry (GC-MS). Data for standard sterols are also reported. The possible origins of these minor components and the significance of their presence are discussed.
