| titleOfInvention | A kind of fat-soluble loguat leaf extraction process |
| abstract | A kind of fat-soluble loguat leaf extraction process, loguat leaf is crushed, and spent glycol butyl ether extracts 2~4 times, obtains concentrate I；Concentrate I adds purified water to dilute, and filters to obtain medical fluid II, and filter residue uses the repeated multiple times washing of purified water again, and supernatant liquid filtering obtains medical fluid III and medical fluid II and merges, is diluted with water, and filters to obtain clarification medical fluid IV；Medical fluid IV is adsorbed by macroporous absorbent resin, is eluted with purified water or butyl glycol ether prewashing, then with butyl glycol ether, obtains medical fluid V；Medical fluid V is concentrated to give no alcohol thick paste VI；Take thick paste VI that butyl glycol ether is added to extract 2~4 times, filtrate is further concentrated to thick paste VII after filtering；It can also be made to recycle butyl glycol ether after completely dissolution to thick paste with butyl glycol ether ordinary least squares leaf extract, then plus proper amount of glycol butyl ether, filtered after extracting 2~4 times, filtrate is concentrated into thick paste VII；By thick paste VII with purified water extraction 2~4 times, extracting solution cold filtration is concentrated, is drying to obtain fat-soluble loquat-leaf extract.It is this production technology simplicity, stable product quality, good in economic efficiency. |
