1,8-Cineole is a predominant terpene found in cranberries. The concentration of 1,8-cineole in cranberries was determined using gas chromatography. A 5.00 g sample of freeze-dried cranberry powder was added to 10.0 mL water to form a cranberry extract. The extract was filtered. A 1.00 ml aliquot was added to a 25 ml volumetric along with a known amount of internal standard (d-14 cymene) and diluted to volume with water. Standards were spiked with a fixed amount of d-14 cymene as internal standard. The following data was obtained: 1,8-Cineole (ug/mL); 1,8-Cineole (peak area); d-14 cymene (peak area) 10.0; 1260; 1880 15.0; 1865; 1850 20.0; 2520; 1855 50.0; 6280; 1865 Sample; 1976; 1840 What is the concentration of 1,8-cineole in ug per gram of cranberry?

Which statement is true? Statement 1: In a paper chromatography that uses a cellulose-based filter paper as stationary phase and hexane as the mobile phase, polar compounds are expected to have higher Rf values than that of non-polar compounds.Statement 2: In paper chromatography, polar compounds tend to outdistance the non-polar substances.
purification of egg yolk vitelline 1) Measure the volumes of 3 egg yolks and mix by adding an equal volume of NaCl solution. 2) Extract the mixture with 3 solid volumes of ether and separate the aqueous phase. 3) Do the same procedure 3 times. 4) Mix the sample with water and rinse. 5) It is expected for the protein to collapse. 6) Some more water is added in order to check whether the collapse has occurred completely. 7) The sample is centrifuged and the precipitate is dried.For each step, explain why that action was taken. for example why is NaCl added? Why is the procedure repeated 3 times?
Why is distillation of cyclohexanol using acid catalyst phosphoric acid a better technique to purofy rather than extraction, recrystallization, chromatography, IR spectroscopy?
Your HRP sample had a concentration of 2.0 mg/mL and you added 10 uL to a tube containing 10 uL of 2X Sample Buffer. You mixed this well and then heated at 75C for 5 min. Then you added 10 uL of this solution to a well of a gel. How much protein did you add to that well?
Upon screening with TLC (made of silica gel) chromatography using hexane/chloroform (3:1) as eluting solution, 3 spotswere detected corresponding to a (A) polyphenol, a (B) tannin and an (C) alkaloid. Write the letters of the answer onthe spots in the chromatogram shown at the picture.
Which statement is true? Statement 1: In chromatography, the compound mixture moves along with the mobile phase through the stationary phase and the components get separated depending on the degree of interaction and adhesion Statement 2: Compound A is more soluble in the mobile phase compared to compound B. Thus, compound A would most probably have a higher Rf value.
Please propose a chromatography-based strategy to purify human insulin proteins that have been expressed in bacterial cells.
We used tab water to extract caffeine from tea instead of using distilled water. How does it affect your result? Explain it scientifically. If you forgot to add anhydrous sodium sulfate, how does it affect your result? Explain it scientifically If you forgot to cap the TLC chamber, how does it affect your result? Explain it scientifically.

If you have 6.61 g of caffeine dissolved in 72.3 mL of water and the extraction coefficient between H2O and CH2Cl2 is 21.51. How many grams of caffeine will extract into the CH2Cl2 layer if you add 87.6 mL?
