| titleOfInvention | The method of luteolin and isoliquiritigenin is extracted from STEVIA REBAUDIANA |
| abstract | The present invention provides a kind of method that luteolin and isoliquiritigenin are extracted from stevioside leaf, specific steps include the following: to be extracted to stevioside leaf using alcohol reflux, filtering, filtrate concentration, add diethyl ether extraction, and upper silica gel column purification, crystallization is concentrated in extract liquor, add alcohol to dissolve rear decoloring, recrystallizes to obtain isoliquiritigenin sterling；Lower liquid adds alcohol to dissolve, filtering, silicagel column on filtrate, and alcohol eluen concentration crystallizes to obtain luteolin sterling.It is extracted simultaneously using stevioside leaf and obtains the luteolin and isoliquiritigenin of high-purity, substantially increased the utilization rate of stevioside leaf, improve added value；The production cost for reducing luteolin and isoliquiritigenin simultaneously, saves stevioside leaf resource；It is handled by Saccharomyces cerevisiae microbe conversion and self-dissolving, favorably improves the yield of luteolin and isoliquiritigenin and stevioside. |
