To extract a qualitative analysis that is contained in saffron Flavonoids. Of our predecessors by improving extraction technology, used solid-phase extraction way to extract a separation, that is, the AB-8 macroporous resin for solid phase, ethanol - water eluate, through multiple-eluting And constantly improve the preparation of conditions, from the extract of red flowers in the isolated flavonoids components. Methanol as mobile phase, with high-performance liquid chromatography to extract flavonoids component in the test, have two peak. Note AB-8 macroporous resin is a good performance of flavonoids Adsorbent, and the use of solid-phase extraction method largely avoid the use of toxic and harmful organic Chemistry, for brevity, and high yield.
Abstract: The key to the satisfaction of hydrogen sulfate catalyst of butyl acrylate. Discussed in detail the amount of catalyst, for alcohol acid ratio, reaction time, with water and inhibitor Esterification of the impact of the results showed that: acid ratio of 1:1.5 alcohol, the amount of catalyst for the reaction of the total XX % Inhibitor for hydroquinone, with water as toluene, temperature control in the 113 ~ 125 \u2103 within the scope of the reaction time is 2 h, the yield up xx%.
Key words: butyl acrylate, catalytic synthesis; bisulfate satisfied; inhibitor
[abstract]
the electrochemistry analytic method is obtains the development instrumental analysis technology, the measuring signal is most early electrical signals and so on electric conductance, electric potential, electric current, electric quantity, does not need the analytical signal the transformation, can the direct recording, the easy automation and on-stream analysis. But the heavy metal examination with concentrates into now the environmental protection subject, the chromium is one kind, it association president the time agglomeration concentrates in the human body, threaten seriously human health. Therefore to chromium examination into now an environmental protection popular work. In ultra molecular chemistry nova--The melon link (Cucurbi[n] turil [n = 5-12]) in the molecular recognition, compound trapping and separate the domain to have broad and the huge application prospect and the development potential. this article uses the polarograph (Q[5]) the link to distinguish three price chromium ion to five Yuan melons the experimental condition to carry on the determination, including the cushion bottom fluid choice, tests instrument's parameter, the experimental technique, to test the electrode, the reaction time choice. Finally carries on the result to discuss, summarizes group of Q[5] to distinguish Cr3+ the best experimental condition. key word: Electrochemistry analytic method, five Yuan melon links, three price chromium ion, recognition, experimental condition
