超临界CO2萃取花椒果皮总黄酮的工艺
Supercritical fluid extraction of total flavonoids from Zanthoxylum bungeagum maxim pericarp
摘要
Abstract
The total flavonoids from Zanthoxylum bungeagum maxim pericarp was extracted by supercritical fluid extraction(SFE) ,and the total flavonoid content in the extract was investigated by the sodium nitrite-aluminum nitrate method with Rutin as a standard product.The effects of pressure, temperature, dosage of chemical preparation and time on extract abilities of flavone were investigated.The optimum technology parameter was investigated by the orthogonal design:the factors influencing the yield were as follows:temperature > pressure > time > dosage of chemical preparation, as a result,the best craft conditions were extraction temperature 50℃, extraction pressure 35MPa,extraction time 150min,dosage of chemical preparation 4mL/g,and the extraction rate was 19.574%.关键词
