[Method]The effects of Tartary Buckwheat ethanol extract on pentobarbital sodium and mice spontaneous action times were recorded. [Result]Ethanol extract of Tartary Buckwheat could prolong mice sleep duration caused by pentobarbital sodium (suprathreshold dosage),increase mice sleep number caused by pentobarbital sodium (subthreshold dosage),and obviously inhibit mice spontaneous action times. [Conclusion]Ethanol extract of Tartary Buckwheat has a function of sedation.展开更多
In this study, the extraction process of aflatoxin B~ from tartary buckwheat bran was optimized with ELISA detection method to determine the optimal conditions for extracting aflatoxin B1 from tartary buckwheat bran. ...In this study, the extraction process of aflatoxin B~ from tartary buckwheat bran was optimized with ELISA detection method to determine the optimal conditions for extracting aflatoxin B1 from tartary buckwheat bran. The results of standard recovery test of blank solvent and sample confirmed the feasibility of ELISA detection method. Orthogonal experiment was performed to optimize the solid-liquid ratio, ultrasonic extraction time and ultrasonic amplitude. The results show that it is feasible to detect aflatoxin B1 content with ELISA method. The optimal ultrasonic extraction conditions were : methanol-water ratio 6: 4, solld-liquid ratio 1 g: 5 ml, ultrasonic extraction time 15 min, ultrasonic amplitude 15 ~. Under the optimized conditions, 1 065.1 ng/L aflatoxin B1 was extracted from tartary buckwheat bran.展开更多
