Abstract

Total saponins from Hetian-jade jujube were extracted by an orthogonal array design and determined by color development reaction with vanillin and perchloric acid.The results showed that the optimal extraction conditions were as follows:70%of ethanol concentration,1:12 of ratio of raw material to liquid,and 30 min of extraction time.The content of total saponins in the crude extract obtained under the above conditions was 9.358 mg/g.A convenient and quick process has been presented for the extraction of total saponins from Hetian-jade jujube.
