Determination of three kinds of flavonoid aglycones in the leaves of Acer truncatum bunge by RP-HPLC;

OBJECTIVE:To determine the content of Flavonoid aglycones in Trachelospermum Jasminoides(Lindl.

Methods The determination of three kinds of flavonoid aglycones was performed with Diamonsil TM -C_ 18 column (4.

The flavonoid aglycones:quercetin,kaempferol and isorhamnetin in sea buckthorn leaves were chosen as the assessment index for researching the static adsorption and desorption capacities of the flavonoid aglycones on five macroporous resins——HPD600,YWD01G3,YWD01F,07C and AB-8.

Flavone aglycone as core material was dissolved with anhydrous ethanol and the amount of core material was the core/wall ratio1 ∶ 9(W ∶ W).

Isolation of soy isoflavone aglycones and inhibition on oxidation of plasma lipoproteins;

Effect of food colloids on thermal stability of isoflavone aglycones in soybean milk

High purity soybean isoflavone aglycones was separated and purified by the following technology: soluble protein was deposited by adjusting pH to 4.

In order to improve the physiological activity of soybean isoflavone, the transformation of glucosides isoflavone to aglycone isoflavone was performed efficiently with the help of the immobilized β-glucosidase.

The study worked a new method that experiment adopted Aspergillus niger as experimnetal stecies, which secrete β-glucosidase, to produce the soybean isoflavone glycoside by solid fermentation.

The article worked a new method that we adopted Aspergillus niger as our stecies, which secrete β-glucosidase,to produce the soybean isoflavone glycoside by solid fermentation.
