从东紫苏中提取木犀草素-7-O-β-D-葡萄糖苷的方法
摘要：
本发明涉及一种从植物提取药物的方法，尤其涉及一种从东紫苏中提取木犀草素-7-O-β-D-葡萄糖苷的方法，对东紫苏利用溶剂提取，将提取后的浓缩液或浸膏溶于水，用弱极性或中等极性的有机萃取剂萃取脱脂，脱脂后的水相再用与水不互溶的低碳醇类萃取剂萃取，萃取相浓缩干燥，重结晶后得木犀草素-7-O-β-D-葡萄糖苷；或者脱脂后的水相过大孔吸附树脂，洗脱剂洗脱，洗脱液浓缩干燥，重结晶后得木犀草素-7-O-β-D-葡萄糖苷；本发明提取工艺简单，制备方便，能耗小，无环境污染，溶剂可循环使用，提取率高，可用于研发治疗心脑血管疾病、支气管炎、哮喘、肺癌等疾病的药物。
摘要（英）：

The present invention relates to extraction of medicine from plant material, and is especially process of extracting luteolin-7-O-beta-D-glucoside from Elsholtzia bodinieri. The process includes the following steps: extracting Elsholtzia bodinieri with solvent, dissolving the extracted concentrated solution or extractum in water, extracting and defatting with weak polar or medium polar organic extractant, extracting the defatted water phase with water immiscible low carbon alcohol extractant, concentrating and drying the extracted phase, and re-crystallizing to obtain luteolin-7-O-beta-D-glucoside. Or, the defatted water phase is adsorbed with macroporous resin and eluted with eluent, and the eluted liquid is concentrated, dried and re-crystallized to obtain luteolin-7-O-beta-D-glucoside.The extracting process is simple, low in power consumption, environment friendly and high in extracting rate, and the product is used in developing medicine for various diseases.
