Detemination of epicatechin,rutin and quercetin in buckwheat by capillary electrophoresis with electrochemical detection;

The prescription design of the soybean isoflavones rutins functional production and the study of preparation technics;

Determination of rutin in buckwheat leaves by HPLC;

Study on the optiunm acidity under technological process of extracting rutinum from flower bud of sophora japonica L.;

The solid surface room temperature delayed fluorimetry (RTDF) of rutinum and paeonol, effective compoents in Chinese herbal medicine was established with filter paper as a solid substrate.

The present paper aims at studing the extraction of natural rutinum fromfagopyrum.

The effects of different extraction solvents,extraction pressures,solvent to material ratios,extraction time and sample particle size on the extraction of mulberry leaf rutin using UHPE were investigated.

Effects of processing methods on rutin content and functional characteristics of traditional buckwheat products;

The high-performance liquid chromatographic (HPLC) and heat-induced oxidation of an aqueous emulsion of β-carotene and linoleic acid methods were used to estimate the changes of rutin content and antioxidant activity of 50% ethanolic extracts from buckwheat ( Fagopyrum Tataricum Gaert )flour before and after heat treatment.

The rutin content of leaf with different growing stage at the Eucalyptus youmanii branch and the bark is determined by spectrophotometric method, also compared with eucalyptus Citrodora and local Eucalyptus robusta.
