Abstract
The extract of celery leaves is studied and the results show the extract of celery leaves extracted by the ultrasonic method has activity on scavenging free radicals.By the orthogonal experiment,the optimum extracting condition is 85% ethanol;solid-liquid radio is 1:18;ultrasonic extracted time is 50 min and 3 times.
A significance statement is not available in the OpenAlex record.
